Job Stories From Gresham, OR
Qualified Crawl Space Installer Gresham, OR

    Not all solutions are created equal, and some installers are more qualified than others. TerraFirma Foundation System Employees are Professional Installers. Tom D. of Gresham, OR has an existing sump pump and vapor barrier that continue to fail year after year. He was fed up with it and began searching the internet for a professional installer. He found called TerraFirma for a free inspection to solve his crawl space crisis.

    Upon inspection, it was impossible to step foot in the crawl space due to four inches of standing water. How could this be with a vapor barrier and sump pump already installed? It makes you think about who installed it. One thing was for sure, a new drainage system was needed and a more powerful sump pump. After pumping out the four inches of standing water, drain tile was installed around the perimeter of the basement to aid in collecting water and draining to a sump pump. The sump pump installed is called Triple Safe. With three separate pumps all-in-one, at it's highest level, Triplesafe will pump 11,500 gallons of water of a fully charged battery.

    A moisture free crawl space or basement means NO MOLD. Mold is every home owners biggest fear. Just because you have a system in place doesn't mean it will work when you need it to most. Make sure you find a qualified installer for all crawl space and basement projects. 

Efficient Drainage Line For Waterproofing Gresham, OR

    Waterproofing any space is boiled down to two main tasks: Collect and remove the water. In some conditions we have seen throughout the years, water collection is performing just fine. Water removal is another story. If moisture is not properly relocated, it tends to collect around the foundation seeping back into your home. Gresham, OR home owner Mary C. noticed water building up around her foundation during heavy rain and was concerned about what negative effects it might have on her foundation. After hearing a waterproofing ad on the radio for TerraFirma, she called to schedule her free inspection.

    By installing drain tile and a sump pump in her crawl space we were sure that all excess water was being collected and removed. The question now was where to relocate the water. By hooking up the discharge line from the sump pump and gutter downspouts to a lawn drainage line 40 feet away from the foundation, water had no chance to recollect near the foundation and re-enter the home.

    Pooling water can have many negative effects. increased humidity in the crawl space, mold development, and in extreme cases, aid in foundation failure. With a simple waterproofing system and drain line from TerraFirma, all these problems can be avoided.

Low spot in floor, sinking footing?
Vicinity of NE Linden Ave in Gresham
My wife and I recently purchased an older home (1923). At some point, it seems an addition was built but unfortunately instead of building a proper foundation for it, it was built on top of the deck. Naturally, its seems to be sinking more and more every day, so I am interested in getting a quote to jack the house up and have a proper foundation installed.
