"We have a cabin on the Northern Oregon coast which rests at the edge of a steep hill. Over the years, we noticed some settling with sloping floors, sticking doors, and a foundation crack. We called Ram Jack West after the local foundation expert in Clatsop County failed to follow up on a promised bid. We are grateful for that lapse because the folks at Ram Jack West were exceptional in the service they provided us, start-to-finish. From the office staff and estimator to the engineer and the team who set the pilings and raised the house in its low spots, we were kept apprised of each step. Communication was excellent. The engineering that goes into a project like this boggles my mind, but everyone we worked with was so confident and knowledgeable, any anxiety I had disappeared fast. We are so thrilled with the top-notch service Ram Jack West provided us and recommend them enthusiastically."

"Greg and his team were wonderful to work with from the start. It's going to improve our house and our life to stop having water in the basement everytime it rains. We can finish our basement and actually use the space now! Thanks for being so easy to work with and delivering a quality drain system."

"They leveled our patio and we were extremely impressed with the professionalism of the crew. Unfortunately, the patio sank a couple of inches within a month and they returned again, at no cost, and re-leveled. We are hoping that it will stay but, whatever happens, it is not the fault of their expertise but rather the ground continuing to shift. That is our personal assessment."

"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

House Leveling FAQs, answered by experts

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Most projects take 1-3 hours, with immediate usability after completion.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

Generally speaking, push piers—or steel piers—are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers.
