4.6/5
John S. John S. SW Sunset Drive

The Terra Firma crew from start to finish was amazing. Josh really did a great job explaining every step of the project and answering my questions as we went along. The Foreman Leo and his crew, it was like they were never there. You wouldn't have noticed my house has been touched nor lifted 3 inches. My overall experience with Terra Firma was excellent and I recommend them, especially these two and their crew for any home repair work applicable.

I was very impressed with the care taken by Jeremy L Schwab and his team of Kyle and Martin. They had unusual challenges removing the deck which was fastened from underneath the boards. Jeremy let me know what was going on and we made decisions together where compromise was necessary. Same with the actual lifting of the house - I was directly involved in reaching the right tradeoffs for how much to lift the foundation. The cleanup was thorough and extra care was taken to do the job right.

Job Stories From Benton County, OR

Oregon State Campus Waterproofing Corvallis, Or

The percentage of homes in Oregon and throughout the northwest that have a basement rather than a crawl space are low; However, as TerraFirma is helping more and more customers, we are seeing more half basement half crawlspace type homes. The waterproofing process, through, is similar with a few added parts for complete water protection.

Jim C. has one of these half and half type homes and was experiencing water coming through the wall cold cracks and in heavy rain conditions coming up from the floor slab. As we know concrete is porous which allows water to seep through at the path of least resistance. The proper waterproofing system called for Waterguard to collect water coming through these two problem areas, and a more powerful sump pump for removal. In this case Smart Pump was powerful enough. In heavier more severe cases, Triple Safe Sump Pump is the best options. To give the basement/crawlspace area extra protection, Cleanspace Wall Liner was installed around the perimeter to isolate the cold and damp cement walls from the space helping to condition the air.

With a new, efficient waterproofing system, Jim C. can be confident that his basement will be dry all the time, the air quality is improved and piece of mind is restored.
