TerraFirma Foundation Systems Before & After

Foundation Repair in University Place, WA
Like many homeowners, the couple who owned this home in University Place, WA had never ventured into their crawl space. They assumed everything under their house was excellent, and their floors had adequate support. When they reached out to TerraFirma to inspect their crawl space for water damage, our System Design Specialist volunteered to go into their crawl space to check their support posts. What he discovered was that one of their posts was 5 inches above the ground. You'll notice to the left of the post some wood that appears to be debris. For years, that debris was the stop gap between the support posts and the footing. Eventually, the debris shifted enough to fall away from the post. In a day, TerraFirma removed the old post and installed our SmartJack support post, which is made from galvanized steel and can support more than 60,000 pounds.

After dealing with this door for years, the homeowner took action and contacted TerraFirma to see what could be done to fix their foundation.

Basement waterproofing in Lakewood, WA
This Lakewood basement had seen it's fair share of bad water damage, and it got to the point where the walls were efflorescent and producing mold. Once the homeowners decided enough was enough, they reached out to TerraFirma. Our System Design Specialist quickly came to evaluate the situation. He concluded that for this basement to stay dry, it needed a proper drainage system and wall system that would allow water to exit out of the home and keep the walls free from moisture. After thoroughly inspecting the basement, Wiles and the homeowner agreed to have TerraFirma install our VaporLoc Elite Wall System and our Waterguard drainage system. With an established plan, the TerraFirma Team crew were able to install all of our waterproofing solutions for this home within one day!
