Design guide for frost-protected shallow foundations
Frost-protected shallow foundations (FPSFs) offer a proven technology designed to substantially lower construction costs in colder climates, enhancing housing affordability for families in many parts of the United States. This document provides step-by-step procedures to assist building professionals in designing and laying a slab- on-grade FPSF. FPSFs save money over conventional designs by requiring less excavation to construct a frost-proof foundation. It is specially insulated along its perimeter to raise the temperature of the surrounding ground and decrease frost penetration, thus allowing for the construction of a substantially shallower foundation. The FPSF is considered standard practice for homes in Scandinavia, where 40 years of field testing has proven it to be economical to construct, durable, and energy efficient. HUD strongly encourages wide spread adoption of FPSF technology in the United States and its incorporation into major model building codes.
