PolyLevel Concrete Lifting & Leveling in Grants Pass, OR

Is your sidewalk or driveway sinking and uneven? How about your patio or front porch steps? Uneven concrete not only looks bad, but it can also be a dangerous tripping hazard. Concrete leveling is faster, less disruptive and more cost-effective than tearing out and replacing the concrete.

TerraFirma uses a process called PolyLevel to permanently lift and stabilize sinking concrete slabs with a high-density polyurethane formula. PolyLevel concrete repair offers many advantages:

  • Lightweight - Won’t add weight to existing soil
  • Waterproof - Won’t wash out
  • High-capacity - Lifts heavy loads
  • Minimal disruption to your slab and property
  • Environmentally friendly

If you have a slab foundation or concrete outside your home that you need re-leveled, TerraFirma is your expert contractor. Call today to schedule your free, no-obligation inspection and estimate!

Our inspectors have a minimum of 10 years of industry experience and their focus is to understand the cause of your specific problem and recommend the best solution for your home. Contact us today to schedule a free inspection of your foundation, basement, crawl space or concrete in Grants Pass or the surrounding area.

Job Stories From Grants Pass, OR
Push Piers Save Sagging Grants Pass, OR Home

Soil settlement causes more pain than just an uneven floor. Cracks in the dry wall will begin to appear throughout the house, windows will be jammed shut, and doors won't fit right. This home is Grants Pass, Oregon was experiencing all these symptoms. The hallway door has been completely stuck shut and only opens with extreme force. Don't let this happen to you. There are ways to restore quality and piece of mind that your home is healthy and will continue to be for years to come. 

With this 6 push pier system proposed by Patrick Dunn, the foundation will be permanently stabilized and, in fact, lifted back to level. By using 6 piers spaced evenly apart around the corner of the suffering foundation, even distribution of force and lift will be applied consistently to the foundation walls. Enough force was exerted to lift the house, close up dry wall cracks and alleviate windows and door jams.

Basement Waterproofing in Grants Pass, OR

    Grants Pass, OR native Jason B was starting to see water leaking into his finished basement. Worried that the water would cause significant damage he went in search of a company that could take care of the issue. While looking on the internet he came across TerraFirma Foundation Systems and decided to contact them.

    That same week he met with their sales representative Ryan Thomas.  Ryan took a look around the basement to determine which products would best suit the problem. He recommended that they install a SuperSump sump pump system. This sump pump is top of the line on the market, with the ability to pump 2220 gallons out an hour, comes with an eight-foot discharge line, and will keep any home water free for years. Along with a WaterGuard system, which is a drainage channel installed along the perimeter of the basement to catch incoming water seepage and direct it towards the sump pump, that basement will be protected from water. Also Ryan suggested the CleanSpace Wall System. This is a vapor barrier attached top the walls that would prevent any moisture from coming through and it will direct any moisture into the WaterGuard drain.

    Now that TerraFirma Foundation Systems installed the waterproofing products on his basement, Jason no loner has to worry about his finished basement getting ruined.

Smart Jacks Put a Stop to Foundation Settling in Grants Pass, OR

    David M of Grants Pass, OR discovered that his foundation was starting to settle. He started to look for someone to help him. While watching television he saw an ad for TerraFirma Foundation Systems.

    David called the office and set up an appointment for Ryan Thomas to some out. Ryan came and did a thorough inspection of the property to determine what products would best help him. Ryan recommended that they install Smart Jacks in the crawlspace. These jacks would provide supplemental support for the failing structure and also will lift the failing floor joists or beams to restore them to their original position.

    With Smart Jacks now installed in his crawlspace, David can walk on his floors and no longer feels as if they are sloping and settling.

When it rains, have water in bsmt. Not sure where all the cracks are. Also had flooding because of a broken sewer line. The 9 inches of rain we got from the big storm a few weeks ago put a lot of water in bsmt.. I'm working on getting the sewer problem resolved, but still need to clean up the floor and fix any leaks.
