Lays the Foundation below the soil freezing, but above the location of groundwater.
If your soil can not ensure the stability of the erected building it is necessary to make a tight cushion of sand and gravel. You can put a thick layer of gravel (35-40 cm) and ramming it tightly until it will not go into the ground.
On weak soil to lay pile Foundation. The distance between the poles shorten. When the tab strip Foundation, the lower part of the base make a wider top.
To avoid deformation of the Foundation on heaving soils (in areas with a high location of groundwater), you need to lay the bottom part of the Foundation below the frost, and inside to make a frame from rebar.
The most common tab - the construction of pier Foundation. The amount of cash investments, their construction is reduced.
For heavy buildings, lay strip foundations. And for greater reliability, make the sand – gravel cushion. Throughout the internal volume of the reinforcing frame. Then, you can be pretty sure that the Foundation will hold any load and will not fail in any type of soil.
Mark the location of the future Foundation. Dig a pit.
Install the formwork. Add a pillow.
Formwork install reinforcement cage.
Pour the Foundation. Pour a solution of their own making or buy ready-made in special machines (mixers).
If you decide to make the solution yourself, then namesevice it better in the mixer. If hand mixing, do not get reliable results.
For mortar - 1 part cement (grade 400), 3 parts river sand and 3 parts fine aggregate. Pour water gradually so as to normally poured from the concrete mixer, mortar.
Drambuie mortar hoe, to get all the frozen bubbles, which lead to the destruction of the Foundation.
The top of the base check laser level.
