with the ground and which transmits the load to the ground (Tomlinson,2001) • Shallow foundation is a foundation constructed in depth of not exceeding 3.0m
from formation level. The depth to width ratio of the foundation is D/B ≤ 3

• Generally, there are two (2) types of foundation:

 Shallow Foundation
 Deep Foundation

D
