Job Stories From Multnomah County, OR
Concrete Leveling Prevents Patio from Sinking Further in Portland, OR Company

    Jim C owns a commercial building in Portland, OR. There was a patio attached to the building that was starting to sink. Jim realized that this could be a hazardous situation eventually so he took to the internet to look for an office. While searching around he came across an ad for TerraFirma Foundation Systems and decided to call them and set an appointment.

    Only days later, the office sent out Vince Mast to look at the situation. He recommended that they do a polyurethane foam injection on the patio to raise it back to its original position. This injection consists of two separate liquids that are combined in the injection nozzle to trigger a chemical reaction. The blended liquids would turn into expanding, high-density foam and will lift the settled concrete.

    Now that the patio is lifted back to its original position using our concrete leveling solution, Jim can have people in his facility and not have to worry about anyone getting hurt because it is unlevel.

Slab Leveling Saves House From Potential Water Damage Happy Valley, OR

    Voids under cement slabs can occur in two main ways. One is that the soil under the home settles. When this settlement occurs a voids results. The second main cause is when water flows under the slab, washing away the soil. Again, this will lead to voids. In the case of Mark P. of Happy Valley, OR sinking slabs have changed the angles, layout and geography around the perimeter of the house. When it rains, the water is now being directed TOWARDS the foundation rather than away. This is a problem.

    The solution is simple. TerraFirma Concrete Leveling! The way this installation works is as follows. A penny sized hole is drilled into the sinking slab. Our concrete leveling solution, a lightweight, quick curing polyurethane is injected into the void. The expansive properties of the polyurethane inflate to evenly fill the ENTIRE void. Due to the high capacity of our concrete leveling solution, the slab is pushed up, leveling the area, and in this case, saving the foundation.

Concrete Leveling Straightens Out Portland, OR Home Slab Work

    Driveways, walkways, sidewalks, and patios aren't installed with the intention to settle and become uneven. They become uneven due to soils settling or being washed out for underneath. The weight of the cement sinks into those voids and you're left with an uneven, unfinished look to your home. In Portland we see rainfall year-round, hence a lot of uneven cement work due to settlement. Bob D. of Portland, OR wanted to fix these issues around his home and wanted to do so without the invasive and expensive process of completely replacing the slabs. After searching online for solutions, he scheduled a free appointment off of TerraFirma's website OregonFoundationRepair.com

    The solution he found was TerraFirma Concrete Leveling. Our solution is a light weight polyurethane that is expansive, has a high capacity and is quick curing. A penny sized hole is drilled through the sinking slab and foam is injected through this hole to fill the void. It's that simple. Because of the properties of our polyurethane concrete leveling solution, you achieve even lifting, no additional weight to soils below, and you can walk or drive on the slab 15-30 minutes after application. Not to mention price and destruction to your property is much less than complete slab replacement.

    Bob now has a new, level driveway, walkways around the house and patio without the "new" price. Not to mention things look much nicer and his home has a cleaner, finished look.

Hot Tub Spa Slab Leveled with TerraFirma Concrete Leveling in Portland, OR

    How many abrupt edges, uneven surfaces, sinking slabs or cracked walk ways do you see around your house? What is holding you back from fixing these problems? There is now a cheap and effective solution to blemishes like these without the expense of replacing the enter cement piece. Mariel and David P. of Portland, OR had a similar problem with a cement slab under their spa. The soil under the slab, over time, had washed out, and the cement slab along with the spa, was sinking into it. After searching through Angie's List for a contractor to help, they called TerraFirma to come out for a free inspection and estimate. 

    As inspected by System Design Specialist Adam Lounsbury, voids had developed under the slab and needed to be remedied. Our concrete leveling solution is a lightweight, expansive and quick curing option to leveling uneven slabs. Our solution is injected into the void, it expands to fill the void, and cures within 15-30 minute after application. The results are the same as destroying and replacing the existing slab but the price is much more swallowable.

    Mariel and David couldn't be happier with the work and look forward to enjoying their spa, sink free, all summer long.

Leveling Slinking Slabs Preping for Home Resell Gresham, OR

    Home owners putting their house back on the market obviously want to get the most out of their investment, a lot of which has to deal with aesthetics and curb appeal. Obviously having a structurally sound foundation, or state of the art, efficient HVAC or waterproofing systems vastly increases the value, but looks go a long way. If you were able to level sinking slabs, eliminate unsightly walk way cracks or remove trip hazards at a price much cheaper than replacing the slab entirely, would you do it? Sharon R. of Gresham, OR said yes. A friend of hers who had this same service done to her house referred us to Sharon who called for a free estimate.

    We refer to the service as TerraFirma Concrete Leveling. Our concrete leveling solution is a lightweight polyurethane with a high capacity. Because of these properties, no extra load is added to the soils below, but is strong enough to support foot and vehicle traffic. A penny sized hole was drilled into the sinking slabs around Sharon's home and our machine injected polyurethane foam. After 15 minutes, the polyurethane had cured leveling sinking slabs, eliminating unsightly cracks and removing trip hazards. Sharon's home is not only safer, but has a new, finished look, perfect for resell. 

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. Our concrete leveling solution 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 our polyurethane foam 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.

Happy Valley, OR Settling Slab Leveled with TerraFirma Concrete Leveling

    Home owner Ken H. of Happy Valley, Oregon noticed that the stamped patio pad in his back yard had began to settle. As much as 1.5" in some places. Ken was done looking at unsightly cracks and the unfinished look to his back yard and wanted to do something about it. After seeing a commercial from TerraFirma, Ken called to set up his free estimate.

    Our quick curing, low density, high capacity polyurethane was injected into the void under his sinking slab. Our solution is then pumped through a penny sized hole and expands evenly to uniformly raise the sunk slab back to level. The solution cures in about 12-20 minutes and clean up is a since. This is a very efficient and cost effective solution to slab repair in comparison to the other option of demolish and replace.

    Ken now has a new back yard patio slab without the price of one just in time for Summer.

Haugen Finishing the Job with Concrete Leveling in Portland, OR

    We have been working with home owner Janet H. of Sherwood, OR since 2009. Her home rests on a property that has been subjected to foundation settlement and soil shifting since she called us years ago, and probably many years before that. Over the years we have permanently stabilized her foundation with a series of push piers and helical piles. This time, Janet had sinking slabs around her property and wanted them fixed without the cost of total replacement. Knowing that we have done great foundation work for her in the past, she called to see if we could help with this type of work. As you could imagine, we were more than happy.

    To solve her sinking slab issue, we first located the voids by drilling through the slab, a hole about the size of a penny, and probing to find the void. Once located our polyurethane concrete leveling solution was injected into the various voids around her property. Our concrete leveling solution has a high capacity to support and lift sinking slabs without adding extra load to the soils. The polyurethane foam also spreads evenly to achieve uniform lift.

    Over the years we have successfully stabilized, supported and lifted a good percentage or her house and property. With these permanent, durable solutions, Janet can be at ease that her foundation is as stable as can be.
