Basic foundation types: deep basement, submerged crawl space, flush crawl space, and slab-on-grade

Image

The goal of foundation moisture management is to construct the basement, crawlspace, or slab in a way that keeps moisture from getting in in the first place

Innovation in Frost Protected Shallow Foundations

Reference

Video describing how a frost-protected shallow foundation (FPSF) is constructed and including use of a stay-in-place EPS (expanded polystyrene) footing form that provides insulation and simplifies the installation of frost-protected monolithic concrete slab foundations.
