TerraFirma Foundation Systems Before & After
  • Basement waterproofing in Lakewood, WA
    Basement waterproofing in Lakewood, WA

    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!

    Concrete repair in Portland, OR

    Over the years, the void left under this Portland, OR home was so substantial, that the concrete on their driveway settled and took part of the home's decorative brick wall with it. After looking at this eyesore for months, the homeowners took action and called TerraFirma to see what could be done to fix their concrete. Our experienced System Design Specialist came out to their home and recommended that we use our concrete leveling foam technology to fill the void under the settled concrete. With a plan in place, TerraFirma went to work and repaired the concrete in one day! Now that the driveway is the level, the homeowner can repair their brick and know that their driveway won't ever settle that bad again!

    Crawl Space Encapsulation in Portland, OR

    With its nearly 7ft ceiling and its wide open spaces, this Portland crawl space was vulnerable to a wide variety of problems, including pest inhabitation and frequent flooding in the winter. After dealing with their crawl space problems for years, the homeowner finally decided to gain peace of mind by calling TerraFirma. Our System Design Specialist, Erik Keyes, quickly came to evaluate the situation. He concluded that the crawl space would need VaporLoc Elite, one SmartJack, A TripleSafe Sump Pump, and two MoistureLoc dehumidifiers to prevent future mold. With a plan set, Nick Maszy and his production team came to the home to start the project. By the end of the week-long job, TerraFirma installed nearly 4,000 sqft of VaporLoc, removed nearly 4,000 sqft of insulation, and replaced one wooden post that had weakened from constant water damage with a SmartJack.

    Everbrace Wall Stabilization in Portland, OR

    This family lived in their home for 35 years without any signs of settling. Over time, and due to a variety of factors - they eventually noticed small cracks and mold starting to grow along the floor of their basement.  They knew these were signs that their foundation may need repair.  Luckily, they called TerraFirma.  One of our System Design Specialists came out to their home for a free consultation and recommended we install an EverBrace™ Wall Restoration System. Many foundation repair options, including anchors and steel beams, have difficulty being used with some types of wall construction such as brick, clay block, fieldstone, or even highly deteriorated and broken poured concrete or concrete block. Such repair options provide points of support to specific areas of a foundation wall and, therefore, still rely on some strength from the existing wall to distribute the resisting force. The EverBrace™ system allows you to keep your existing foundation walls by permanently “bracing” them against the pressure exerted by the surrounding soil. This essentially gives you the safety and security of a new foundation without having to replace your existing foundation. Plus, each installation is customized for your home, meaning existing windows and doors won’t be covered up. This system is zinc-coated, so there is no need to worry about rust or corrosion. The homeowners were very pleased with the completion of their project and were happy they didn't have to worry about cracks and moisture.  They now have peace of mind moving forward knowing their basement is protected, and the value of their home restored.
