The depth of the foundation depends on several factors -
- the bearing capacity of the soil
- the nature and make up of the soil
- the seasonal depth of the water table
- the severity of the winter soil temperature
- whether there are point loads to be dispersed
- the design of the foundation - strip, pad or raft
It offers useful guidance for building within certain parameters.
A competent building professional - preferably an architect or engineer with PI cover - should be retained to design the foundations.
