Foundations for Log Houses
A foundation plan will be provided by the manufacturers so this can be adapted in thickness downward according to you local conditions and building regulation laws.
Concrete bases for the construction of residential log houses and cottages are mostly built to finish 300cm above the general level of the site, so as to help prevent excess moisture splashing onto the lower logs.
One of the first things to be investigated is the depth and makeup of the soil structure, this is done by the builder or architect with the aid of a drill to check the different layers and their thickness.
Problems can arise with a high-water drainage of excess moisture around the foundation, these sites may have to be piled.
It would be in your own interest to consult you local building inspector for types of foundation needed in he are you intend to build, as this could make or break the budget as some specialist bases are VERY costly.
