"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."

House Leveling questions, answered by experts

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Costs range from $500 to $1,500, depending on the size and condition of the area.
