Job Stories From Corvallis, 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.

Vicinity of NW SILKTASSEL CT in Corvallis
A single wet spot in the basement that comes 1-3 times in winter when raining heavy/day long.
Vicinity of NE Owl Pl in Corvallis
Our home is mostly crawl space foundation, the garage is attached and is on a slab. the back corner of the garage has dropped about 2 inches. You can see it in the roof line, and I got out my laser and measured, the slab is cracked and drops 2 inches or so and the ceiling line also drops 2 inches. Looks like piers will be the best way to jack that corner back up level with the rest.

Vicinity of NE Newcastle Place in Corvallis
Our home was built in 1975 so I'm sure doesn't have the tie-downs to the foundation. Want to know what it would cost to have that done. And whatever else we should consider to be earthquake ready.
Vicinity of NW Oak Ave in Corvallis
We built an addition last year and we've had water in the crawl space ever since it was completed. The water is there ~November-May and then dries up during the summer. I run a sump pump on an extension cord to keep the water from getting too high but this is not a permanent solution. Need a better solution.

I currently have no known issues with moisture and am most interested in any energy benefit from your system
Vicinity of SW Willamette Ave in Corvallis
After a heavy rain plus a bank on south side of basement the water came through in laundry room and bathroom. Found bedroom with dampness near baseboards. Had carpet man come in and check and he put fans on and dried a lot of it. He checked all rooms and dampness showed up in all 3 bedrooms and family room. I think I need someone like you to help me find the source. I do have my lawn man working on trying to correct the bank. My home was built in 1964
