How to correctly lay and fasten the first crown of timber on the foundation, installation video. What to put between the foundation and the timber. A framed crown made of timber.

The laying of the very first crown of a house made of timber must be done very thoroughly and with a mathematical approach so that the walls of the house stand exactly at 90 degrees. Correctly lay the first crown of timber on the foundation not such a difficult task if you do everything thoroughly and prepare well for this event. And if you want one who will serve you long years, take this stage of construction very seriously.

Checking the foundation horizon

Even before laying the first crown, we lay two layers of waterproofing, a backing board, and then an additional layer of waterproofing. But before you begin installing waterproofing on the foundation, you need to check that it is horizontal. A simple level can give a large error and for this it is better to use its hydraulic version, which you can buy or use a transparent hose for this.

The difference in level should not exceed 1 cm throughout the entire foundation. The plane can be leveled with a solution using a backing board different thicknesses or different quantities waterproofing layers. If the difference in level is significant and there is no time to level with the solution, you can use bars of different thicknesses under the backing board or electric plane adjust the thickness of the backing board.

Selection and preparation of material for installation of the first crown

The next stage in the process of laying the first crown of timber is the selection and processing the right material. Under no circumstances should you just take the first timber you come across and start installing it. Indeed, in the future, your choice will determine the time it takes to replace the lower crown. Poorly processed timber, or timber mounted without taking into account the selection requirements, will lead to more early start work to replace the lower crown.

Choosing the best timber for the first crown is the key to a long “life” of the house

Selecting the right material for the first crown

We begin to prepare the timber for the first crown in advance. As soon as you deliver the lumber to the site, you need to choose the most best bars, without large quantity knots, without blue, straight without flaws. Based on the cut of the annual rings, you need to choose a beam whose density of rings is as high as possible, and the beam itself is the middle part of the tree. At the end you should see circles diverging from the center.

Processing timber for installation of the first crown

The wood must be completely coated with liquid several times. bitumen mastic, mixed with used machine oil, so that this composition penetrates deeply into the structure of the wood. You can also use special impregnating agents for deep processing wood

The ends do not require processing; they should remain clean. Excess moisture will be removed through the ends.

The service life of the lowest crown and the time it will stand before replacement will directly depend on the degree of processing of the wood structure. Therefore, take your time and thoroughly prepare all the material for the lower crown. And although there is still quite a long way to go, the first step has already been taken!

Attaching the lower crown and checking the geometry

Fastening the lower crown at corner joints

The first crown does not need to be attached to the foundation. The fact is that a house made of timber is itself a heavy structure and will stand perfectly without fastening with anchors. Corner joints are made without locks, joining the timber at the ends. This is done so that it is possible to replace any timber, without the need to disassemble in the corners. The timber in the corners and at the junction of partitions is rallied metal fastenings: fastening perforated plates or brackets.

Before final fastening of the timber in the corners, you need to check the aspect ratio of the house and the correct, one might say “ideal” geometry of the house, so that the corners are exactly 90 degrees. If the lengths of the opposite sides are equal to each other, and the diagonal distance of the house between the opposite corners coincides, we can conclude that the corners of the house are correct. To check the corners, you can use a factory sheet of plywood or OSB if you attach it from the inside of the beam to inner corner and place a beam on it.

The durability of the future construction depends. This is a fundamental, basic issue, and it must be taken with the utmost seriousness, because the cost of error is too high.

Selecting and preparing material

The timber for the first crown should be of the highest quality. The selection criteria are simple:

No knots or damage on the surface.
No blue on the ends. Darkening is a sign of fungal infection.
High density of annual rings. It is desirable that the rings diverge from the center of the cut - this means that the beam is made from the core of the tree.
The wood must be dry (you must use “winter” wood).
It is advisable to use timber made of oak or larch - they are much stronger than pine.

Before laying, the timber is impregnated with bitumen mastic. To make the impregnation absorb deeper, you can add a little used oil to it. The procedure is repeated 2-3 times.

An important nuance: the ends of the timber are not treated with mastic! This is done in order to ensure the release of moisture. The impregnated wood is allowed to dry completely, after which it proceeds to direct installation.

Preparing the foundation

The first thing to do after pouring the foundation is to check its geometry. A height difference of even 1 cm will subsequently lead to serious distortions in the structure of the building. The quality of the foundation is checked with a regular water level - if a difference is detected, the plane should be leveled with concrete mortar.

The next stage is providing waterproofing. Concrete has the property of raising moisture and transferring it to higher elements, so the durability of the entire house depends on the quality of waterproofing. The base is thoroughly impregnated with a bitumen mixture, filling all cracks and gaps. A layer of roofing material is laid on the bitumen (the tape should be 20-25 cm wider than the foundation) and heated gas burner. The joints of the tapes are overlapped and heated additionally. The surface of the roofing material is again impregnated with bitumen and covered with another layer.

An important nuance: during the construction of the foundation it is necessary to ensure adequate ventilation underground This is done using embedded pipes or boxes. Such holes will prevent moisture from accumulating under the floor and reduce the likelihood of fungus.

Laying the first crown

The first beam is laid not on concrete, but on wooden planks 15 mm high, located across the foundation strip every 30 cm. This is done in order to prevent contact of the first crown with the waterproofing. Some builders prefer to use a special backing board instead of slats, but the benefits of such technology raise reasonable objections. Opponents of the board claim that it rots faster than timber, and at the same time forms an additional inter-crown gap in the most vulnerable place of the wall.

After laying the beams on the slats and checking the horizontality, the resulting gap is filled with ordinary polyurethane foam. The corners of the first crown are connected with metal staples. It is not necessary to attach the timber to the foundation: the weight of the entire structure is enough to provide the house with the necessary stability. In some cases, it is possible to attach the first crown to anchors located at the corners of the foundation.

An important nuance: the joining angles must correspond exactly to 90 degrees. Otherwise, the diagonals of the intersection will be broken, which in turn will lead to unwanted deformations of the building.

How to decorate the facade of a frame house?

One of the features frame house– the ability to decorate it with almost any material. Lots of options: from vinyl siding to real brick. When choosing a material, you need to understand that it brings not only aesthetic, but also practical...

Before erecting the walls themselves, builders have a reasonable question: how to lay the first crown in the house? The first crown of the house must be installed thoroughly, using mathematical calculations, so that in the future the walls will be as smooth as possible, standing at a 90-degree angle. This work is not very difficult, the main thing is not to rush and prepare thoroughly for it.

Mounting diagram bottom trim and waterproofing for the first time.

To lay the first crown for a house made of timber, you should lay down at least two layers of waterproofing, then a backing board, and a waterproofing layer on top of it.

It is important to ensure effective system waterproofing for the foundation before laying the first crown of timber houses. For these purposes, roofing felt is laid twice, and then a one-time installation of Stekloizol is carried out. All layers should exceed the width of the base by approximately 25 cm along the entire length of the perimeter.

All the bars that are laid must be pressed closely against each other. It is unacceptable to form even small voids in the wall, and especially in its lowest area. Since in the future it is on the bottom that the floor will be hung and this is where the greatest loads will be placed.

The beams are fastened to each other using metal dowels, deepened into the wall by 3 cm, and finished off with a wooden mallet. If there is a slight bend on the beam, it is laid with its straight edge turned downwards. In some situations, it is necessary to additionally fasten the lower beams using nails or staples, which are placed through the two crowns of a bathhouse or sauna made of timber.

Before directly laying waterproofing on the surface of the foundation, you must check that its outer plane is clearly horizontal. Check the horizontal level of the foundation using a hydraulic level, since an ordinary level often shows some error. The dimples should not exceed 1 cm over the entire surface of the foundation. When the unevenness is more than 1 cm, the surface is leveled with a solution or another layer of waterproofing.

Which timber to choose for the lower crown of a log house?

Suitable quality material should be prepared in advance. The first crown for a bathhouse made of timber must be formed with a material distinguished by its high quality characteristics:

The bars should be selected even.
The knottyness on them should not be very pronounced.
It is better not to use material with a bluish tint; it will not be suitable for laying the lower crown.
You should take bars with the maximum density of rings: this raw material is made from the middle part of the wood.

Assembly diagram of the first crown of a log house for a house made of timber

Before you start laying the crown on the foundation of a timber house, you need to think through and ensure the durability of the entire structure as a whole. For these purposes, slats are laid out, pre-treated with an antiseptic, which are 10-15 mm thick. A gap of 25-30 cm is made between them.

The slats are needed to prevent the crown of the timber house from coming into contact with its foundation. This measure allows you to extend the service life in the future. log bathhouse by providing additional protection against rotting.

The sequence of assembling a crown for a bath made of timber

The first layer of beams is placed on the exposed slats. The voids between the timber and the base are foamed.
After this, use a level to measure the evenness of the surface, since if the lower crown is uneven, the wall will also be crooked.
After eliminating the defects, the voids are filled with polyurethane foam.

As already noted, the preparation of timber should be done in advance. Let us repeat that it should have a minimum of knots, no blue stains and be even with high density tree rings.

The first crown of timber should be processed at mandatory, and this needs to be done by coating all the wood several times with bitumen mastic, coupled with working off, so that the mixture is absorbed as deeply as possible into the beam for the bath. You just don’t need to process the ends, since they must be perfectly free so that excess moisture present in the wood can be removed through them. The service life of the lower crown and the period of time after which there will be a need to replace the old timber will depend on the quality of wood processing.

Often the first crown is not attached to the foundation - under the weight of the house it will not budge even without anchors. At the corners, the joints are made without locks, the beams are joined at the ends. The beams in the corners at the junction of the partitions are connected with metal plates or brackets.

Construction good home from timber is a difficult process in which each operation must be carried out with special care and reason. Much attention should be paid to laying the first crown, because this is what will affect the quality of the entire structure. If you do this step correctly, the walls of the house will stand straight, forming angles of 90 degrees.

The first crown should be laid slowly, in accordance with all requirements and technical standards. In addition, you need to prepare for work no less carefully. Even before you start laying the crown of a house made of timber, you need to take care of waterproofing the foundation.

Waterproofing before laying the first crown

So, before you start laying waterproofing, you need to check and inspect the top of the foundation. To perform this action, you will need to prepare a hydraulic level. If the difference is more than 1 cm on the surface of the foundation, then it is worth carrying out additional work related to its leveling. As a rule, this will require preparing a concrete solution.

Experts recommend initially laying two layers waterproofing material, then a laying board and then again a layer of waterproofing. The materials used for this process must be fastened so that they extend beyond the edges by 25 cm on either side.

Search for quality material for the first crown

The material for building a house made of timber for laying should be prepared in advance. The first crown should be made of high quality material. It should be:

With a minimum number of knots on the surface;
With a perfectly flat surface;
The material should not have a blue tint; this is not suitable for laying the first crown;
The density of the beam rings should be maximum - then it becomes clear that this material is made from the middle of the tree.

Before placing the first crown (larch), it must be treated with an antiseptic

After selecting the timber, you need to thoroughly lubricate it with bitumen mastic, previously mixed with the waste. A similar composition is needed so that the impregnation is well absorbed into the wood. It is not worth treating the ends of the timber, otherwise the moisture will not be able to “leave” the tree. The thoroughness of processing and impregnation will influence many factors, including the durability and reliability of the first crown, and, consequently, the entire house made of timber.

Laying the first crown

Laying the first crown looks like this:

It is necessary to lay slats on the layer of waterproofing material. They must first be treated with an antiseptic solution. The distance between the slats should be 30 cm. The width of each slat individually is 15 mm;
It is necessary to lay beams on top of the slats. They will form the first layer. Thanks to the use of slats in this process, it is possible to provide the beams reliable protection, and also prevent their direct contact with the fundamental surface. If this process is carried out correctly, the durability of a log house will be significantly increased;
A gap will be formed between the timber and the foundation. Under no circumstances should it be left, otherwise the building will quickly deform and become askew. This void can be filled using polyurethane foam. It will firmly and reliably fasten both sides, on for a long time, guaranteeing density;
Next, you should again determine the surface evenness using a hydraulic level. If the horizontality of the surface is disrupted after the installation of the first crown is completed, the walls will be assembled unevenly. This problem can be solved through additional surface leveling.

Fastening the first crown

Points of view regarding attaching the first crown to the foundation differ greatly. Some believe that it is imperative that the crown be firmly attached to the foundation surface, while other builders and experts argue that this is not necessary.

Building a house from laminated veneer lumber or any other type has a lot of weight, so they believe that it will stand well and firmly without the use of anchors and additional fastening. In such a situation, docking without a lock is used. When this is done in the future, you can replace any timber without dismantling the corners of the building. In the corners, simple staples or metal plates are used for connection. When building a house with your own hands, each person will independently choose whether he will attach the crown to the foundation or not.

Attaching the timber to the strip base

To attach the first crown of a timber house to a strip foundation, you must adhere to the following procedure:

Purchase elements for fastening to the foundation, preferably with a reserve;
Check the level of surface level using a hydraulic level. If the unevenness exceeds 1 cm, then it is worth eliminating it with a solution. If the unevenness is less than 1 cm, then you can put planks under the beam;
Select the docking method: into a bowl or into a paw. Both options are strong and reliable. On the Internet you can watch videos of how professionals assemble them;
In the beams prepared for laying to the foundation, you need to drill holes slightly smaller than the anchor studs that will be concreted into the upper part of the foundation;
The corners of the first crown must be connected with dowels or nails;
After this, you need to check each corner using a level. If any irregularities are found, you need to remove them with a plane.

Attaching and laying the first crown in this way is not an easy task. If done correctly, the house is guaranteed to last a long time.

Mounting on a pile-screw foundation

Harness is mandatory and necessary element laying if there is a screw foundation. It all has to do with what the piles represent. point support, so some places will be more stressed than others.

So, first you should make sure that all the piles are correctly installed on the foundation. If there are some deviations, then it is necessary to eliminate the irregularities by cutting out the timber in the required places. In the corners of the lower crown you need to place anchors filled with mortar. On the outside, the corners must be covered with aluminum corners. After this, in order for all sections of the timber to be joined, you need to make cuts on them. The first one needs to be done with bottom side, second from the top.

It is recommended to fill the joints with jute. This method is convenient in that it acts as a strapping lower crown. Thanks to this, additional strength is achieved. A video on this installation and connection method can be viewed on the Internet.

Laying angles

The first crown should be correctly placed on the foundation so that its angles are equal to 90 degrees. This strict rule All construction of a house made of profiled timber is observed and should not be disturbed. Thanks to this, it will be possible to ensure accurate and correct geometry of the house. If there is a discrepancy, the sides of the house opposite each other will differ in length, in addition, the diagonals of the intersection will also be violated. If the condition regarding the corners is met correctly, then the house will stand for a long time without deformation.

To others an important condition It is considered to carry out all activities at a calm pace without haste. Otherwise, this may result in serious problems, the solution of which will require large financial costs.

Completion of installation

After the lower crown and the beams in it are fastened with dowels or nails, the anchor need not be installed.

There should be 2 bolts on one piece of timber if the house has short walls;
Using building level you need to check all diagonals and angles. Eliminate unevenness with an electric plane;
After attaching the beams to the base, you need to install vertical racks.

Despite the fact that the issue of attaching timber to the foundation has both supporters and opponents, the choice remains with each builder.

Laying the lower crown on the foundation timber house- important technological process. It will depend on him big number factors, including the durability and strength of the house. It is not difficult to connect all the beams qualitatively, but you need to constantly monitor the evenness of the surface.

Scheme of fastening the lower trim and waterproofing under the first crown.

To lay the first crown for a house made of timber, you should lay at least two layers of waterproofing, then a backing board, and a waterproofing layer on top of it.

It is important to provide an effective waterproofing system for the foundation before laying the first crown of timber houses. For these purposes, roofing felt is laid twice, and then a one-time installation of Stekloizol is carried out. All layers should exceed the width of the base by approximately 25 cm along the entire length of the perimeter.

How to build a subfloor that provides a durable floor covering?

After laying the first crown and treating it with fire protection, they begin to arrange the subfloor for the timber bathhouse. The work is carried out in several stages:

All available corners must be laid out clearly at 90 degrees so that the geometric proportions of the house are considered correct.

A check is made to ensure that the lengths of the two opposite sides are the same, and the diagonals between the opposite sides of the timber house coincide. If everything is correct, this means that the angles are accurately drawn.

When laying the lower rows of the crown of timber baths, one should not rush, as the work will affect the evenness of the walls.

Before starting to build a house, everyone has a question: how to lay the first crown of timber? It is necessary to lay the first crown of a house made of timber as thoroughly as possible, with mathematical calculations - so that the walls of the future house stand perfectly exactly at an angle of 90 degrees. This is not too difficult to do - the main thing is to take your time and prepare very well for this work.

Before laying the first crown, it is necessary to lay at least two layers of waterproofing, then a backing board and then another layer of the same waterproofing.

Waterproofing between the log house and the foundation

Before laying the timber, ensure maximum waterproofing of the foundation. To do this, lay roofing felt twice, and then lay glass insulation once. All laid layers must exceed the width of your foundation by 25 centimeters along its entire perimeter.

The beams being laid must touch each other as tightly as possible; in no case should even the slightest voids be left in the wall, especially its lower part. After all, it is on this part that the floor is subsequently hung and all serious loads are placed on it.

The beams need to be fastened together on metal dowels to a depth of 3 centimeters, and they are finished off with a wooden mallet. If the beam has a slight bend, lay it down with its even edge. There are cases when the connection of the lower beams requires additional fastening using staples or nails (they need to be installed through 2 crowns).

Before laying waterproofing on a roofing felt foundation, check that its upper plane is strictly horizontal. You need to check the horizontal position with your own hands using a hydraulic level, since a simple level often gives a large error. The difference should not be more than 1 cm over the entire plane of the foundation. If the difference in level is greater, level the surface with mortar or an additional layer of waterproofing.

Laying the first crown of the log house - assembly diagram

Before laying timber on the foundation, we need to take care of the durability of our structure. To do this, we lay out slats pre-treated with an antiseptic, approximately 10-15mm thick. The distance between them is 25-30 cm (see picture).

Well, we put our first layer of beams on top of the exposed slats.

The slats are necessary to prevent the crown from coming into contact with the foundation. This trick will greatly increase the life of the log house, thanks to additional protection from rotting, and fill the gap between the timber and the foundation with polyurethane foam.
Next, we check with a level to make sure the surface is even - after all, an uneven first crown results in an uneven wall.
After eliminating the inaccuracies, fill the gap with polyurethane foam.

The timber must be prepared in advance, even when delivering materials to the site. Choose the best beams that have a minimum number of knots, are as smooth as possible, and without blue stains. The timber must be selected according to the cut of the annual rings - choose the one whose ring density is as high as possible (in this case, the timber should be the middle part of the tree). At the end of the cut you should see circles that diverge from the center.

The selected wood must be completely coated several times with bitumen mastic (liquid), in combination with working off, so that the composition is absorbed as deeply as possible into the future timber. The ends do not need to be processed; they must be clean, because through them the wood will be removed. excess moisture. The service life of the lower crown and the time before it becomes necessary to replace it directly depend on how you process the wood.

In some cases, there is no need to attach the first crown to the foundation - a house made of timber will be quite heavy and will stand very well on the foundation without anchors. Corner joints are made without the use of locks; the timber is joined at the ends. Such joints are made so that in the future it will be possible to replace any timber without dismantling the corners. In the corners, the timber at the junction of various partitions is connected by metal plates or brackets.

Although many builders tightly fasten the beams to each other and to the foundation.

All angles must be strictly 90 degrees, then the geometry of the house is considered ideal. You need to check that the lengths of the opposite sides are equal, and that the diagonals between the corners (opposite) of the house coincide - if everything is correct, then the corners are drawn accurately. When working on laying the lower rows, you should never rush, because this determines what kind of walls you will get during further construction.

If you want your house to be a solid, capital construction that will please not only you, but also your heirs for many years, then you need to approach its construction with special care, observing technologies and standards. It is important to understand that the strength and durability of the building depends on each action. That is why we will figure out how to lay the first crown of timber - after all, this is the key to a successful construction result.

How to place the first crown?

Norms

When laying the first crown of timber, it is important to study all technical standards and do the work efficiently at all stages.

Even before installation, pay special attention to the arrangement of waterproofing.

The foundation must be checked using a special building level; if there is a difference of more than one centimeter, then the surface will have to be leveled. This is usually done with concrete mortar.

Making the foundation

When the leveling material has completely dried, you can begin laying waterproofing, preferably in several layers. It must be secured so that the waterproofing material extends 25 cm beyond the perimeter of the surface on all sides.

What material to use

Laying the first crown of timber requires the highest quality, proven material. It must meet the following requirements:

have no nicks or knots;
have a smooth surface;
be made from the heartwood of a tree. This can be determined by the density of the rings;
do not give away blue.

If you have already chosen timber, then also stock up on bitumen mastic, which will be useful for processing. The end parts of the timber should not be touched with impregnation at this stage, as this may lead to loss of moisture from the wood. Scrupulousness in performing these operations will make the first crown of a house made of timber unusually stable, durable, and ensure the reliability of the entire structure.

Installation procedure

It is necessary to perform the following sequence of actions:

lay slats pre-treated with an antiseptic on top of a layer of waterproofing material, keeping a gap of 30 cm between them, as can be seen in the photo;
Place the beams on the slats, which will form the first layer. The slats act as a buffer between the timber and the surface of the foundation, preventing them from touching;
Fill the resulting space with high-quality mounting foam, leaving no gaps. The foam will securely hold the materials together, preventing the building from deforming or tilting;
measure the evenness of the surface using a building level. If unevenness is discovered, the first crowns of a timber house are laid crookedly, then they must be leveled so that the walls of the house are smooth.

Fastening

The question of how timber crowns should be laid causes a lot of disagreement among experts. Some believe that the crown should be attached to the foundation, others insist that such fastening is completely optional.

Since a building using laminated veneer lumber has a large mass, professionals claim that it will be stable even without anchors. In this case, it is important to use joining technology without a lock, so that any of the beams can be easily replaced without complicating the process of disassembling the corners. If you are building a house with your own hands, then after studying both opinions, you can decide how you will attach the lower crown of the house made of timber.

Strip foundation

How to attach beams to strip foundation? To connect the first crown of timber, follow the following instructions:

purchase fasteners, make sure that they are in abundance;
check the evenness of the surface with a building level;
eliminate any irregularities using a special mixture;
choose the methods of joining the beams: in a bowl or in a paw. In order to determine the optimal one, watch the training video;
drill holes in the beams of a smaller diameter than the anchor pins, which are then concreted into the base;
connect the corner parts of the first crown with nails;
check all corners again with a level, remove any unevenness using a plane.

Pile foundation

If your house has this type of foundation, then for installation it is necessary to tie it. This is because the piles do not provide uniform support and the pressure may be greater in some areas.

Make sure the piles are positioned correctly in the base. Eliminate deviations by sawing the timber in in the right places. Position anchors at the corners of the lower crown of the beams, fill them with solution. Using aluminum corners, strengthen outside corners Then carefully cut the beams to ensure their reliable joining. Fill the joints with jute. This method is preferred by most novice builders, as it is very convenient, and the building is given additional strength due to the first crown. In addition, there are a lot of master classes on the Internet in which experts share the secrets of this installation method.

Corner condition

It is important to ensure the connection of timber crowns at an angle of 90 degrees. This is a golden recommendation for construction from corrugated timber, violation of which can be fraught with consequences during further construction.

If you follow the rule exactly, the geometry of the house will not be disturbed, opposite walls the diagonals of the intersection will be the same in length. Such a house will last a very long time without being subject to deformation.

Final stage

If the lower crown of the beams is securely fastened with dowels, then there is no need to use additional anchors. Check if you followed the sequence of actions:

if the walls of the house are not very long, then there should be at least two bolts on one piece of timber;
check corners and diagonal connections with a building level;
firmly install the vertical posts into the base.

Remember that haste in this matter is completely inappropriate; the final result depends on your actions: the fundamental nature of the structure, its quality and further comfort during living.

-> Sections of the site -> Log house -> Do-it-yourself log house -> The first (framed) crown of the log house.

The lower crown works in the most difficult conditions - close to the ground, more wet than other crowns during rain and snowfall. Therefore, traditionally, special attention was paid to its production.

Before laying the first (lower) crown of the log house, do not forget about waterproofing, which is 2-3 layers of rolled bitumen waterproofing material laid between the foundation and the logs to prevent the walls from getting wet from the foundation.

The first (flashing) crown is made from the thickest logs.

If you have such an opportunity, then it is best to make the first crown from the types of wood that are most resistant to rotting. Larch or oak are best suited for this purpose.

It is obvious that sides 1, 3 and 2, 4 are at different horizontal levels, which differ in height by half the diameter of the log. Therefore, the first crown, from which the entire frame begins, can be realized in two ways.

Despite some inconveniences, such a crown will be more durable due to the fact that the logs are subject to minimal processing and remain almost solid.

To prevent rotting of the logs of the first crown, special attention must be paid to thoroughly antiseptic surfaces in contact with waterproofing (hewn surfaces). Before laying, coat the hewn surface with an antiseptic using a brush 3 - 5 times. By the way, this is the only place in the bathhouse where I used antiseptic.

Backing boards should not be coated with melted resin (bitumen) or wrapped in roofing felt. A tree clogged with resin or wrapped in roofing felt will rot very quickly.

An inter-crown sealant is laid between the foundation waterproofing and the backing board, between the backing board and the first crown.

The process of making a crown molding is shown in a series of videos frame (first) crown of the log house.

The framed (first) crown of the log house is video technology.
