An Introduction to Spread Footings and Mat Foundations

COURSE NO: G02-008
An Introduction to Spread Footings and Mat Foundations
Course Highlights

This online engineering PDH course provides an introduction to the design of spread footings and mat foundations for buildings and other structures such as towers on cohesive and cohesionless soils.


When required footings cover more than half the area beneath a structure, it is often desirable to enlarge and combine the footings to cover the entire area. This type of foundation is called a raft or mat foundation and may be cheaper than individual footings because of reduced forming costs and simpler excavation procedures. A mat foundation also may be used to resist hydrostatic pressures or to bridge over small, soft spots in the soil, provided the mat is adequately reinforced.


This 2 PDH online course is intended for civil engineers, structural engineers, geotechnical engineers, geologists and other design and construction professionals seeking an introduction to methods and techniques for designing footings and mat foundations for buildings and other structures such as towers.

Learning Objectives
