Waterproofing Basements

by DoItYourself Staff

Waterproofing basements can prevent water damage from HVAC systems, ventilation systems, pipe condensation, sump pumps, and leaks in walls, ceilings and foundations. Waterproofing basements will save homeowners from disaster if maintenance systems like electrical wires, water and sewage pipes, and garbage disposals are installed in the basement.

Steps for waterproofing basements

The primary method of waterproofing basements is applying a waterproofing coating. Prior to that application, a homeowner should inspect block walls to ensure that they are in proper condition. If not, they should brush away loose mortar and broken block, remove surface dirt, remove old paint with a sandblaster or wire brush, and use quick-drying cement to fill in cracks, holes and wall/floor joints.

Hydrostatic pressure can be the result of a variety of conditions, including rain runoff flowing toward a house, a high water table, faulty gutter systems, and wind-driven rain. Waterproofing coating systems are designed to prevent the passage of water that is under hydrostatic pressure. Film-forming waterproofing coatings for waterproofing basements are designed for above and/or below ground and interior and/or exterior applications.
