Photo Album: Basement Waterproofing in University Place, WA

Album Description

It's common for homeowners to turn their basement into a bedroom, but in the Pacific Northwest, it's important to make sure that your basement is waterproof and free from water damage if you plan on having someone living in the room.

The homeowners of this lovely house in University Place, WA knew that living in the northwest means the possibility of water intrusion in their basement. Before they moved someone into the basement, they called TerraFirma to see what would need to be done to properly waterproof the home.

After carefully evaluating the basement, our System Design Specialist sat down with the homeowners and recommended that we install our TripleSafe Sump Pump, a VaporLoc Elite Wall Barrier, and a Waterguard drainage system. All three of these products work together to ensure that the basement won't suffer from moisture damage or have any seasonal flooding.

With a plan in place, our crew went to work and waterproofed the entire basement within a day.
