There are several kinds of shallow footings: individual footings, strip footings and raft foundations. Note that the footings have been cast on top of beds of plain cement concrete PCCwhich has been done to create a level, firm base for the footing. In other words, the entire surface of the pile, which is cylindrical in shape, works to transfer the forces to the soil. Learn everything about building construction. Bathroom Fixtures. Shallow foundations can be made in depths of as little as 3ft 1mwhile deep foundations can be made at depths of 60 - ft 20 - 65m.

The load of the building is transferred through the pile onto the strong layer. The idea is that each footing takes the concentrated load of the column and spreads it out over a large area, so that the actual weight on the soil does not exceed the safe bearing capacity of the soil. The load therefore bypasses the weak layer and is safely transferred to the strong layer.

If they cannot be built below the frost line, they should be protected by insulation: normally a little heat from the building will permeate into the soil and prevent freezing.
There are two types of pile foundations, each of which works in its own way.
