Basement Waterproofing Project in Portsmouth, NH

This Portsmouth, NH basement had water intrusion problems, as seen by the damp floors and efflorescence on the foundation walls. Efflorescence is the white powdery substance on the walls that happens when water comes in and evaporates, leaving behind a residue of minerals and salts. To waterproof the space, we poured a new slab floor with WaterGuard perimeter drainage system. BrightWall panels were installed on the walls to give a fresh, clean appearance and seal out moisture. Their new TripleSafe sump pump will pump water away from the home, keeping the basement dry.
