Cost-Effective Concrete Lifting Without Replacement

Slabjacking in Washington

Sunken concrete doesn’t always need replacing. Slabjacking restore slabs quickly and affordably by filling voids beneath the surface and lifting concrete back into place.

A Proven Method to Lift Sunken Concrete

What Is Slabjacking?

Slabjacking is a time-tested process of lifting sunken or uneven concrete by pumping a specialized material beneath the slab. This fills voids, stabilizes the soil, and raises the concrete back to its proper level. It’s a faster, less expensive alternative to tearing out and replacing concrete.

This method is ideal for sidewalks, driveways, porches, and other flatwork where soil settling has caused sinking or cracking.

Common Signs You Need Slabjacking:

Sunken concrete slabs around your home

Noticeable gaps between concrete and adjacent surfaces

Cracks forming due to uneven pressure

Water pooling on low spots of concrete

Tripping hazards caused by uneven slab edges

Common Questions About Lifting Sunken Concrete

Slabjacking FAQs

What’s the difference between mudjacking and polyurethane slabjacking?

Mudjacking uses a cement slurry, while polyurethane uses lightweight expanding foam. Both lift slabs, but polyurethane is less invasive and longer-lasting.

Will slabjacking fix all cracks in my concrete?

It corrects unevenness and prevents further cracking, but existing cracks may still need sealing.

How much does slabjacking cost compared to replacement?

It’s often less than half the cost of tearing out and replacing concrete.

How durable are slabjacking repairs?

When done correctly, slabjacking provides long-term stability and can extend the life of concrete by decades.

What causes concrete to sink in the first place?

Soil erosion, poor compaction, heavy rainfall, and plumbing leaks are the most common culprits in Western Washington.

Is slabjacking safe for driveways and garage floors?

Yes. Our methods are designed for high-load areas and can restore proper grading for safe vehicle traffic.

Will slabjacking affect my landscaping?

Update 4/12/26 The company reached out to us, came to our home and made a plan to properly lift our house. The work was done in a timely manner and we had a much better experience with them this time around. We are very happy with how things turned out. Awful company. We paid over $38,000 to raise our foundation 1.5”. It started cracking and they were unable to do what they said they could. They “stabilized “ it and left with our savings. It was the biggest waste of money and I suggest you go elsewhere. Garbage. Our house feels like it’s sinking more.

So I had some work done by r and r back in 2019. I had six piers put in and really enjoyed Corey the owner… fast forward to 2026 and the other part of my house started having weird sounds and a crack in my ceiling… I live on a hillside and tons of water comes my way and a user error with a downspout may have caused more issues… I made an appointment to have him come Out and do an inspection with a bid…. It’s pretty rare these days to not feel like you have gotten taken… Cory did all the measurements and well it appears the house is just settling. The house was built in 1980 by the original owners and was definitely not built straight. Anyway… Cory literally put me at ease and said. “Let’s just keep these measurements and check them out in a year or so. “He could have easily have just said… “yup. You need six piers….” He didn’t. I highly recommend r and r foundation… thanks for being honest… it goes a long way! Also… when I do need the work done… I, of course, will be using them!

House built in 1913 did not disappoint with challenges with a leaking foundation into the basement. But, R&R came through and I am able to feel confident that any further water issues are no longer. If the opportunity presented itself, I would hire them again.

I had them come out to my house to look at an issue of water seeping into my garage which is built into a hill. For reasons that have nothing to do with them, I didn't end up getting the work done. However of the four companies I had look at it, R&R's assessment was easily the most thorough. They are the only one that did any significant inspection outside of the building rather than just inside the garage and their prices were comparable to the other companies I checked out.

Had R and R do some work on our older home that needed an update to the crawl space foundation posts a few years back. Work was accomplished in a timely and professional manner. Now in 2025, we are selling our home in a slow market and want to upgrade. We need to show the new buyers the application to transfer the foundation warranty ahead of the inspection in a few days as a show of good will to close the home. R and R's marketing manager, Jordan, was able to accomplish this promptly within one day for us and really set us up well to help close our home. While the foundation repair was important, it was years later, being able to connect with R and R again, and show the new buyers the work they had done and that it was done by a reputable company, that helped seal the deal.
