They are essentially a hole dug into the ground filled back in with concrete to create a strong base for your deck. Pile doesn’t have a footing. Usually the vertical steel is run inside of horizontal hoops and the hoops should have a 3 inches of clear cover.
Caisson types
Generally, these caissons construct of r.c.c or steel. In effect, your footings act to spread the heavy load of the deck from the surface of a support post over a larger surface of the soil so the ground can adequately support it. Drilled caissons are constructed up to the deeper depth when compared to the masonry/concrete pier foundations. Use f’ c = 3000 psi and ƒy = 50 ksi.

In effect, your footings act to spread the heavy load of the deck from the surface of a support post over a larger surface of the soil so the ground can adequately support it. The more footings your deck has to distribute the total load, the less weight each footing will need to carry. Drilled caisson are cylindrical shape foundations.

The amount of steel required will be a function of the maximum moment, the concrete strength, and the diameter of the foundation. The word caisson is derived from latin capsa [1] which means box or case. Design a square reinforced concrete footing for the following conditions: Pneumatic caissons are open at the bottom & closed at the top. Drilled caissons.

To provide a leveled base for. Caisson foundations, also known as pier foundations, are prefabricated hollow substructures designed to be constructed on or near the surface of the ground, sunk to the desired depth and then filled with concrete, thus ultimately becoming an integral part of the permanent structure. This creates a problem when the building settles but the utilities.
