Hydrostatic Pressure
Hydrostatic pressure is a basic concept in waterproofing that refers to the force of water pushing against surfaces like basement walls and foundations. Think of it like the pressure you feel when swimming deep in a pool - the deeper you go, the stronger the pressure. In construction and waterproofing jobs, professionals need to understand and deal with this pressure to prevent water from seeping into buildings. When you see this term in resumes, it usually means the person has experience in preventing water damage in buildings, especially in underground or below-grade structures like basements, foundations, and parking garages.
