Foundation Design

As the lowest and supporting layer of the structure, the foundation is a critical part of any building and must be carefully designed.

Foundation types

Foundations can be divided into two types, deep and shallow foundations

Piles – are a deep foundation. The primary purpose of a pile is to transfer the whole structure’s load onto a deeper layer of soil, which is generally harder than the top most layers. Piles can be further divided into two types, displacement piles and non displacement piles.

Displacement piles - Displacement piles are piles that are required to be driven into the ground. Most displacement piles are propriety products – so, each manufacturer has different specifications from the next.

Non displacement piles - are piles that are made in situ. Usually, a hole is drilled in the ground casing and reinforcements are placed, before the concrete is poured. However, faster methods such as Continuous Flight Auger are used.

Footings and bearings – Lighter structures such as residential housing may utilise spread footings as their foundation choice. The spread footings are popular on softer grounds as they spread the load over a larger area. Footings can be considered as shallow foundations.

There are many types of foundations to suit the different type of structure.
