Houses made of wood have many advantages, and therefore do not lose their popularity, even though there are new materials and attractive construction technology.But as is known, all have disadvantages.And one of the most important for this type of buildings - the fragility of the tree itself.

If construction is carried out "in the mind", the operation of log term, without repair, is at least half a century.But is it always so in reality?In practice, the first element of the house, which is usually in need of restoration or replacement is lower crown framework.

This part of the structure more than others in contact with moisture.Because skilled craftsmen, and is recommended for use only its tab larch, and qualitatively selected and prepared.This variety of wood when wet as it may seem strange, it is only with the passage of time stronger.

How many wooden houses built in reality?Even if the construction is not a team of migrant workers, and specialized firm if all the subtleties of technology followed?Material is harvested "off-season" and also badly dried out, workers do not have the proper experience and expertise, waterproofing is made of poor quality, and even the cheapest brand of roofing material.

worth just to clarify that there are no illusions about the ease of self-repair of the part carcass - this process is rather complicated, and in some cases it is simply impossible with their own hands.The situations are different, as well as the extent of damage the wood.Therefore, we consider all the known variants of repair or replacement of the lower crown, and the reader will decide whether he will be able to perform any actions without the assistance of a professional, depending on local conditions and their own capabilities.

«Spot" repair

This technology is applicable, if the wood is damaged only on any one or more small areas of the lower zone.

Option №1 .In this case, cut out the rotten place, and instead set a new "details".

Option №2 .Instead of the wooden parts of the resulting opening is filled with brickwork.

Pros - ease of repair.No need for practical skills, special adaptations, attracting professionals and substantial financial investment.

Cons - the formation of new places of joints, which leads to increased heat loss.In addition, the strength of the assembly is reduced.

partial dismantling of the foundation

At the site where the rot is detected, understands the upper part of the foundation of the house.Naturally, this method is not always feasible, since the possibility of such repair is largely determined by the type of foundation.For example, if the tape is mounted from the w / w units, this option is not necessary.

free access to the log (the beam) of the lower crown, the owner will not be difficult to replace the rotten sample a new one.

Pros - relative availability of technology and low cost of operations.

Cons - reduction in the strength characteristics of the building base, which negatively affects its durability.

walls Dismantling

This restoration of the crown is considered the most effective.

Pros - an excellent result.Such repairs are significantly extends the operating life of the structure.In addition, it is possible (if necessary) the partial repair the wall.

Cons - complexity;high costs in time and money.Alone with such work does not handle, so you have to raise additional working hands.

Lifting jack log

This method - the most common in self-repair of the lower crown.

Pros - an optimal combination of performance and its cost.At the same time, you can at the site, if necessary, to update (or enhance) the waterproofing layer foundation.

Cons - requires experience, knowledge and strict observance of the technology works as well as the availability of special lifting equipment.Naturally, this technique requires time-consuming.You can not be discounted and the formation of new joints when using jacks.

In the private sector this technology (lifting log) is most common.And one of the reasons - many homeowners, or simply do not pay attention to some rotten portions of the lower crown, or wait "until recently", delaying the timing of repairs.Therefore it is necessary to draw the reader's attention to some moments.

Stages of

• The first is to assess the condition of the structure of angles - whether carcass fall apart in the process of recovery?If the connection method is selected unreliable, it is best to consult with a specialist.As an alternative - to use a support frame to displace up structure.
• With saws (convenient chain) on the rotten parts of doing openings sufficient for the production of jacks.As a minimum - 2 pieces, and then, with a small length of the wall.
• Lifting is carried out simultaneously by all the established mechanisms.Here the main focus - the uniformity and coherence of workers, to avoid distortions.
• Installing a new crown made parts.2 blank - from the corners to the jacks 1 - between them.They are aligned, and rods devices are omitted.
• After recess jacks of the landing "slots" are put in their place fitted the size of the log pruning.
• All joints are sealed with a flexible insulation material (mineral wool, hemp, jute, and the like).

The article considers only the general principles of production repair activities on updating the lower crown.Each structure is characterized by structural features, the degree of wear and a number of other parameters.Before making a final decision, you should thoroughly understand all the intricacies of the work.

What to consider

same time will have to update the waterproofing of the foundation.In the private sector the most common material for this purpose - roofing material.And yet it is not recommended to stack it.Even the quality of its kind serve no more than 3 - 4 years .And considering what the difficulty is repair procedure outlined above, it is better to buy, though expensive, but also more reliable material.For example, "evroruberoid".

Traditional processing workpieces using machine oil or liquid bitumen is unlikely to be the elements of the lower rim enough, especially if it's not a larch.On sale there are many chemical / drugs, impregnation which provides reliable protection of the wood from rotting.Given the importance of this structural element, the lower crown, spare money for the purchase of such funds is not necessary.

During "spot" repairs when it detects corrupt section should identify the true extent of damage, as visually make it virtually impossible.After the defective place in the balance beam (construction) will be cut, it is necessary with the help of improvised tools (ax, chisel) to try to expand it.All discovered "the flesh" should be deleted, and the bared ends of the blanks are processed by special means rot (read more about ognebiozaschitu).

Repair Cost

To understand the appropriateness of the repair work with their hands, familiar enough with approximate prices for the replacement of the lower crown.For the typical structure of 8 x 6 the cost of materials (with their pre-treatment) amount to about 10 000 .Plus - the dismantling of old and installation of new pieces.It still about 17 000 .Therefore, taking into account the unforeseen costs, less than 30 000 rubles not count.
