Basics of Frost Protected Shallow Foundation Design

Andrew J. Bibb, P.E.

Course Outline

Shallow Frost Protected Foundations are a cost effective alternative to conventional spread footings constructed below the frost line of the locality.  This course will review the theory and the ASCE Standard (ASCE 32) adopted by reference into the IBC code for this type of foundation.  The Revised Builder's Guide to Frost Protected Shallow Foundations published by the U.S. Department of Housing and Urban Development includes much of ASCE 32 and will be used as a companion document to the course notes.  The course covers typical construction details and includes worked out examples showing how to put ASCE 32 into use.   

The course covers the following topics:

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will:


Intended Audience

This course is intended for structural engineers and architects.


Benefit to Attendees

At the end of this course the attendee will have the personal knowledge and data to design IBC code approved, cost effective, shallow frost protected foundations for their clients.


Course Introduction

Section 1805.2.1 of the International Building Code, both 2003 and 2006 editions, requires foundations for all but the most minor of structures to be constructed in such a manner that they will not be adversely affected by freezing of the surrounding and supporting soils.  This protection can be achieved by constructing the foundations on bedrock, constructing the foundations so the bottom of footing is below the frost depth of the locality, or by protecting the foundation per the requirements of ASCE 32.  This course will cover the basics of the last method.

Course Summary

Frost protected shallow foundations can be a cost effective alternative to constructing foundations below the frost line.  This course and the HUD builders guide will show how to design a code compliant shallow frost protected foundation.
