Bill concrete for the foundation on its own

First, make markings according to previously selected drawings. This is best done using segments of reinforcement and fishing fishing line, which can stretch and at the same time not sag. So, make markings and dig a pit on it. The most common depth for him is forty centimeters (for a regular private house). After installing formwork in the pit. You can start filling with concrete. Now there is a ready -made concrete dry mixture on sale, which is more profitable to buy than cook it yourself.

The necessary volume of concrete is calculated as follows: they multiply in meters, the length and width of the future foundation. Thus they receive the desired volume of concrete, which should always be taken with a margin. Brand of concrete should be 400-450. You can also order concrete m200.

When pouring, the concrete should be liquid enough to spill every corner of the formwork. If he is loose. then it is diluted with water to the desired state. For obstacles to the formation of air bubbles inside the foundation, freshly laid concrete tamped or vibrated. For these purposes, use a special vibrator or ordinary shovel or perch.

I also want to add that if it began to rain during the fill, then the concrete is covered to prevent dissolution of the upper layer. In the heat, on the contrary, concrete is advised to moisten with water.
