TerraFirma Foundation Systems Before & After
  • Basement Waterproofing in Eugene, OR
    Before
    Basement Waterproofing in Eugene, OR
    After

    Basement Waterproofing in Eugene, OR

    This Eugene basement had suffered water damage, causing the walls to crack and creating an unhealthy environment for the homeowner. Wanting to resolve this problem, they called TerraFirma.  Our System Design Specialist evaluated the home and recommended installing the VaporLoc Elite, DryTrak, SuperSump Plus, and feedlines in the basement. All these products used together create a full perimeter drainage system that would divert the water away from the home!

    Crawl Space Encapsulation in Roseburg, OR

    This Roseburg crawl space had mold growing from unwanted moisture lurking inside it. To keep their crawl space dry to stop the mold from spreading, the homeowner reached out to TerraFirma.  Our System Design Specialist came out and recommended installing the VaporLoc Elite Bundle, MoistureLoc, Everlast Door, Drain Title, and TripleSafe Sump Pump in the crawl space to create a full perimeter drainage system. While these keep the crawl space dry, these products will also keep energy costs low and improve home air quality.

    This Roseburg crawl space had suffered from not one but two rodent infestations! Rodents can use crawl spaces as a breeding ground, deteriorating air quality and impact a homeowner’s health. Luckily, they called TerraFirma to help. Our System Design Specialist quickly came to evaluate the situation. He recommended installing the VaporLoc Elite Encapsulation System and SuperSump Plus. This solution would help remove the pests and keep water out of the crawl space for good!
