Having basic knowledge about the different types of housing foundation is key, especially if you are buying an off plan, you can monitor your building from start to finish. A Foundation is a lower portion of building structure that transfers its gravity load to the earth.
foundations are divided into two MAIN categories:
shallow foundations and deep foundations. The words shallow and deep refer to the depth of soil in which the foundation is made. Shallow foundations can be made in depths of as little as 3ft (1m), while deep foundations can be made at depths of 60 - 200ft (20 - 65m). Shallow foundations are used for small, light buildings, while deep ones are for large, heavy buildings.
These 2 main categories of Foundation are divided into 3 which are
RAFT FOUNDATION: Raft Foundations, are most often used when basements are to be constructed. In a raft, the entire basement floor slab acts as the foundation; the weight of the building is spread evenly over the entire footprint of the building. It is called a raft because the building is like a vessel that 'floats' in a sea of soil.
Raft Foundations are used where the soil is week, and therefore building loads have to be spread over a large area, or where columns are closely spaced, which means that if individual footings were used, they would touch each other.
PILE FOUNDATION : A pile is basically a long cylinder of a strong material such as concrete that is pushed into the ground so that structures can be supported on top of it.
Pile foundations are used in the following situations:
When there is a layer of weak soil at the surface. This layer cannot support the weight of the building, so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock that is below the weak layer.
When a building has very heavy, concentrated loads, such as in a high rise structure.
Pile foundations are capable of taking higher loads than spread footing
PAD FOUNDATION : Are generally shallow foundations, but can be deep depending on the ground conditions. They are a form of spread foundation formed by rectangular, square, or sometimes circular concrete 'pads' that support localised single-point loads such as structural columns, groups of columns or framed structures.
Are you wondering what kind of foundation we use at Bridgeport? Ask us in the comment section and we will be glad to respond.
