How foundations are built?
Although foundations have been made from a number of materials — stone, block and even treated wood — reinforced concrete is used in the vast majority of new homes. The contractor erects wooden forms, installs steel reinforcing bars (“rebar”) between the form faces, then fills the forms with poured concrete.

Installing rebar (and using safety caps) “Boom pumping” concrete. Polysteel stem wall forms, stems poured, rough-in plumbing.
What is foundation its types?
There are generally two main types of foundation ( i.e. shallow & deep foundation) for constructing the structures like houses, buildings, etc. A foundation is a lower part of a building structure that transfers its load to the soil (earth) and the structure must distribute the load equally within tolerable limits.
What is foundation and how it works?
Foundation is the part of structure below plinth level up to the soil. It is in direct contact of soil and transmits load of super structure to soil. Generally it is below the ground level. Whenever construction workers begin work on a new building, they must first assess where and how they will build the foundation.

Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.
How long can a foundation sit before building?
According to Concrete Network, concrete should be allowed to cure for at least seven days before it’s built on. However, waiting longer will greatly reduce the risk of the concrete cracking. Concrete continues to cure up to 28 days after it is poured, at which point it reaches maximum strength.
