Foundation installation: Basic rules and requirements
First of all, on the ground, a layer of crushed stone is poured on the future building of foundations, then it is compressed, then it will prevent the passage of water. At the same time, the formwork of foundations from boards or timber is adjusted. The following compulsory layer – asphalt or the so -called skinny concrete is applied to the already compacted crushed stone.
On a concrete base, waterproofing is laid in rolled form. Such rolls are rolled out in several layers with fit on each other and with the entrance to the formwork, fastening to it with the help of ordinary nails.
On the waterproofing surface, for its better protection, I lay out a screed with a thickness of 45-55 mm from a cement-sand solution. The device of additional waterproofing of the foundation can not be carried out if groundwater does not take place.
