These raise the home one and a half to four feet from the ground. Cinder or concrete blocks extend from the footings and close the space off except at ventilation areas.

## How do I know my foundation depth?

The depth of foundation is determined by inputting:Plasticity index of soil.Water demand of the tree.Mature height of the tree.Distance of relevant tree to nearest part of foundations and distances elsewhere if stepping foundations.Allowance for climatic conditions.

## How deep is the foundation of a 3 story building?

Foundation walls for two (2) story buildings under 25′ 0″ in height shall be a minimum of ten inches (10″) in thickness, measured horizontally, through a cross-section of the foundation. Foundation walls for three (3) story buildings over 25′ 0″ in height shall be a minimum of twelve inches (12″) in thickness.

## How deep do wall foundations need to be?

A concrete footing should be 100mm deep by 300mm wide if the footing is for a free standing wall. The footing should be increased to 150mm deep and 450mm wide if the wall being built is a retaining wall. For larger retaining walls an engineer may need to be approached for advice.
