It supports and anchors the super-structure of a building from movement and transmits its loads directly to the ground. To prevent damage from sinking soil or unstable ground condition, a properly designed foundation does more than just supporting a house. The design can keep moisture or rising damp out, insulation can contribute to keeping out cold temperatures and resists movement of the earth around it.

In New Zealand, there are 3 typical types of foundations: Engineered Rib Raft slab, conventional foundation and slab and pile subfloor or block subfloor construction. However, it is best to evaluate which one to use for the type of house you are building and the location where you’re building.
