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!

Job Stories From McMinnville, OR
Smart Jack Interior Settlement McMinnville, OR

    Home owners Rich and Jill of McMinnville, OR are experiencing some sagging on the first floor of their home. The reason was that after construction, the weight of the furniture was just too much for the flooring and load beams to handle. After an inspection by Adam Lounsbury, there was no sign of mold or rot in the load beams, just simply too much weight. To restore structural integrity, a 3 Smart Jack system was installed.

    Since there is a basement to this home, 6' Smart Jacks were needed and will be installed under the first floor pads that have sunk. Smart Jack Post Replacements were installed at 2 of the Smart Jack locations to provide optimal strength. This project took no longer than half a day and we were finished before Rich and Jill knew it.

    After completion of this quick fix'er up, Rich and Jill are no longer bouncing in their house while walking through, and they are confident it will be like this for time to come.
