Frost-Protected Shallow Foundations: Phase II, Final Report

This historic report is the second and final phase of an investigation into frost-protected shallow foundation (FPSF) technology. A FPSF is a practical construction method in cold climates where more costly conventional foundation methods are typically used. The report found that houses and other structures may be built on shallow, slab-on-grade foundations in cold climates when properly insulated to protect against frost heave.
