Job Stories From Hillsboro, OR
Sinking Front Slab Drains Water Under Home Hillsboro, OR

    Slabs around a home property are grated to aid in drainage of water away from the foundation. When voids form under these slabs settle and tilt back toward the foundation, now all of the water is draining right back under your home. Probably not something you want to happen. Hillsboro, OR home owner Howard E. noticed this re-slanting on his front porch. Realizing the potential hazard, he searched the internet for a company that could help re-level his font porch and protect his foundation. He found TerraFirma Foundation Systems.

    The solution was quick and easy, not to mention it the entire project only took a few hours to save potentially thousands of dollars and miles of head aches. PolyLEVEL was injected into the voided area under the front porch slab. This solution is similar to Mud Jacking minus the mess and the expense. Not to mention PolyLEVEL is a more durable and long lasting solution.

    Howard's front porch is as good as new, and he can be confident that his foundation is protected from unwanted water because of it.

Proper Crawl Space Systems Restore Health and Value to You and Your Home

During times in the northwest when it just doesn't seem to stop raining (which is somewhere between 8 and 9 months of the year), do you every worry that your crawl space or basement is improperly waterproofed and water is seeping into your home? A little water won't hurt, but a lot can be detrimental to you, your family and your home's overall health.

Chris A. from Hillsboro, Oregon was experiencing some leakage in the crawl space and is concerned about the long term affects it might have. As this trend continues, you get standing water in the crawl space, which can lead to high levels of humidity and temperature. This will not only rot away at the wooden beams under your home, but can also lead to mold development which become airborne and breathed in by you and your family. 

Chris did the right thing and didn't hesitate to call us for help. By installing an effective drainage system leading to a sump pump for removal and a new 10ml vapor barrier, Chris can now be worry free that he is keeping the family healthy and restoring the value and health to the home.

I have/had a musty smell coming up through the floor into my living room and there still seems to be something lingering that is impacting air quality in the room. I would like to get the crawlspace checked out to see if there's a problem down there with moisture and/or mold or mildew.

We live in the downtown Hillsboro area. We have water entering the basement from an unidentified source. The basement is partially finished, which is complicating our hunt for the source of this water. We would like a bid on 1) seeking the source and 2) once the source is identified, a further bid on repair. Thanks!

Jeffrey Bryant front patio leveling.
Vicinity of SW Imperial St in Hillsboro
Our front porch slab has sunk 2-3 inches next to the front door. There may be other concrete in need of stabilization. I would like to know if it is worth trying to improve the earthquake readiness of the foundation and single-story ranch house on it.

I would like receive information on basement encapsulation and foundation crack repair.
Vicinity of NE Jackson Street in Hillsboro
We bought the house in Nov. 2017. The previous owners said there wasn't a problem with water in the basement. We had minor problems in Jan 2018 that seemed to go away with diverting downspouts. But this year, with heavy rain, we have had water seep up through the concrete and create a pool in the middle of the floor. There isn't a drain and there's nowhere for the water to go. We want to look at waterproofing options as well as sump pump.
Vicinity of SE Pine St in Hillsboro
This house is built on pillars and there is some visible shifting that happens seasonally. Need to determine if this is a problem before starting on other house renovations.

Vicinity of Larch Street in Hillsboro
Crawlspace with extremely high levels of moisture, 3 beams are rotting from the stems, no vapor barrier. Need a bid for all work needed to be done on the foundation/crawlspace.
Vicinity of in Hillsboro
There is a window that has not closed since we purchased the house in 2015. I have noticed other things that may indicate an issue. I am a worrier and I would like the peace of mind knowing that our investment is being taken care of and part of that is following up on my concerns.
Vicinity of NE Morning Sun Dr. in Hillsboro
We are attempting to sell our home in Hillsboro Oregon. The home inspection noted several 'concerns' including cracks in foundation as seen from the crawlspace and cement slab in the back yard which is no longer exactly in its original position and is creating a trip hazard when walking around the house to the side yard. We have an offer, which is pending, but we need to get an estimate of what it would cost to address the cracks in the foundation and/or level the slab. So... it's important that we make a decision about whether or not to have these issues fixed ourselves.
