So, how to lay timber on the foundation. First, you need to choose the right timber. It should be smooth, natural color without blueness, with a minimum number of knots. The lower crown of the house experiences constant loads, places with knots withstand it worse, this must be taken into account.
You should examine the purchased wood, paying attention to the density of the annual rings on the beams. The denser they lie, the stronger the timber itself.
You need to check the humidity of the wood material. If your moisture meter shows a humidity of 10-14%, that will be great. You can immediately lay such timber and the shrinkage of the log house will be minimal.
Timber is usually brought with a humidity of 18-20%, and you can also build a log house from it for shrinkage. Gradually, during the shrinkage process over 1-2 years, the timber will acquire an equilibrium moisture content of 10-14% and then it will be possible to start finishing the log house
If defects are detected, the timber is laid with it facing up. If the geometry of the timber is slightly distorted, then it is laid with the convex part on the side of the log house.
Before laying, the timber should be carefully treated with an antiseptic and fire retardant. The antiseptic will protect the timber from biopathogenic microflora. The fire retardant will create a layer on the products that is protected from combustion. Only after such treatment can the timber crown be laid on the foundation.
Before laying the timber on the foundation, you need to make sure that it is level. The foundation for a timber house should be as level as possible along the horizontal plane. So that you do not have to level the timber itself under it.
