After all the necessary measures were carried out regarding the design and preparation of the site for construction, build the foundation. Given the soil features, use different types and forms of the foundation.
The aerated concrete blocks have low strength to breaks, so they are not used for the foundation, but, as a rule, a continuous foundation created from reinforced concrete plates is used. He is practical and reliable. First, a foundation pit is pulled out around the entire perimeter of the structure, the width of which is equal to the width of the concrete blocks. Its depth should be at least half a meter. A wooden formwork is installed in the pit and poured with a mixture of sand and concrete.
After the concrete hardens, the iron locking reinforcement is laid out, it is connected in the corners of the foundation with welding. Such a foundation can withstand the building, regardless of its height. How reliable and stable the structure, soil fluctuations should not affect.
A drainage device is erected around the perimeter and laid out by roofing ground, thus, protecting the foundation from water flows.
Sometimes a strip foundation is used to build cottages, but then they dig a pit, but a trench, a depth of half a meter around the entire perimeter of the building and fall asleep with sand.
