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.

Garage is bulging in the middle and concrete on the walkway and driveway have justing edges which are tripping people. I want to hopefully level the garage at least. The rest is negotiable. I'm also curious about the crawlspace encapsulation. We have a sump pump down there but if I could avoid the moisture altogether that'd be awesome.

Have some garden concrete paths that have sections that have cracked and fallen, also some that have tilted, and some that voids have appeared under them. You can see subsidence in the garden. You can see the paths on Google maps, satellite view.

My home had a working foundation drainage system, which drains to the street, but after some city work and a walkway project the system was damaged. I am looking to have an additional section added under the sidewalk to the street and fix any other damage. Thank you.

When we bought the house a couple of months ago it was recommended we replace the vapor barrier. After the heavy rains of the past few days it seems a decent amount of moisture found it's way under the house and now we've got a fairly persistent "odor" in the house now. We've also determined that the lack of insulation down there is making the process of heating the home much harder. Additional information: Main Area of Concern: Crawl Space
NE Hood Street in Hillsboro
I need a quote for bat insulation repair in the crawl space of a 70s ranch home. Some of the insulation has fallen and needs stapled back up between joists, and I would also like an inspection for moisture. The vapor barrier was in excellent condition at a home inspection 3 yrs ago. The house is 30x40.
