Different types of shallow foundations

This construction video briefly explains different types of shallow foundation.

A shallow foundation refers to a type of foundation that disperses loads of a building to the earth very adjacent to the surface, instead of transferring to a subsurface layer or a range of depths as performs a deep foundation. Shallow foundations consists of spread footing foundations, mat-slab foundations, slab-on-grade foundations, pad foundations, rubble trench foundations and earthbag foundations.

Shallow foundations are built up where layer of soil at shallow depth (upto 1.5m) can provide support to bear the structural loads. The depth of shallow foundations is usually below its width.
