Title: System Design Specialist

Kevin Wiles from TerraFirma

After spending 15 years in the wine industry, Kevin Wiles is no stranger to the different types of soils the Pacific Northwest has to offer.

 

As a System Design Specialist, his extensive knowledge of how our region’s expansive soil shifts home foundations and damages basements and crawl spaces ensures that the solutions he offers homeowners are permanent and efficient.

    Basement waterproofing in McMinville, OR

    This McMinnville basement had dealt with so much water intrusion over the years that the walls were efflorescent and producing mold. After a few too many rainstorms, the homeowners had enough and reached out to TerraFirma.

    Our System Design Specialist, Kevin Wiles 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, Drake Wimberly and his crew were able to install all of our waterproofing solutions within one day!
