Combatting Subterranean Hydroustatic Pressure: A Technical Guide

Lead Author

Eng. Morris Njau

Deep dive into the mechanics of hydrostatic pressure and the specified engineering protocols for permanent subterranean protection.

Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. In construction, this often refers to the pressure groundwater exerts on a building basement wall or floor.

The Engineering Challenge

Without proper drainage or waterproofing, hydrostatic pressure can force water through cracks in the foundation, causing significant structural damage over time.

The Solution: Bituminous Membrane Systems

Our lead engineers specify multi-layered bituminous membrane systems that provide a robust barrier against even the most aggressive groundwater conditions.
