Footings on Reactive Soils: Site Classes, Slabs and Movement

You'll learn: Read a site classification correctly, understand what the footing design assumes about soil moisture, and manage the site practices — drainage, plumbing, trees, owner handover — that keep those assumptions true for the life of the building.
