Concrete Leveling & Polyurethane Raising
Concrete leveling & polyurethane raising involves restoring sunken concrete, repairing cracks, and leveling sidewalks, providing a cost-effective solution to replacement.
Foundation Raising & Polyurethane Slabjacking for Damaged Concrete
Foundation raising and polyurethane raising — also known as slabjacking, poly lift, or poly lifting — are two techniques often used in tandem to restore the structural integrity of a home or building suffering from foundation settling or shifting. Foundation raising involves lifting the entire structure or specific sections, typically by installing hydraulic jacks beneath the foundation. These jacks slowly raise the foundation back to its original level, addressing common foundation settlement issues such as uneven floors, cracks in the wall, and misaligned doors and windows. This technique stabilizes the foundation and corrects the vertical displacement.
Polyurethane slabjacking complements foundation raising by targeting sunken or settled concrete slabs. This method involves injecting a polyurethane foam mixture beneath the foundation or concrete slabs. As the foam expands, it fills voids in the soil and lifts the slab back into place. The expanding foam creates a durable support layer that helps prevent further settling. After the polyurethane injection is completed, the injection hole(s) is patched with cement, resulting in a level surface.
When used together, foundation raising and polyurethane slabjacking can provide a comprehensive solution, addressing both the vertical lifting of the structure and the stabilization of concrete surfaces. In partnership with 1-866-SLABJACK, R&R Foundation Specialist provides both services to ensure your home or building is restored to its original level and protected from future movement.

Why Choose Polyurethane Slabjacking?
Polyurethane concrete raising achieves the same leveling results as traditional mudjacking with a lightweight material that requires smaller and fewer injection holes. One of the main advantages of slabjacking is that it is less invasive and more cost-effective compared to traditional concrete replacement methods. The process is quicker, requiring minimal disruption to the surrounding area. Since slabjacking doesn’t involve tearing out old concrete and pouring a new slab, it reduces labor costs and downtime significantly and can usually be done for less than half the cost of pouring new concrete, as the costs of demolition, removal, and landscaping are eliminated.
Additionally, the expanding foam used in the process offers excellent long-term stability, preventing future sinking and voids from forming. This makes slabjacking a practical and sustainable repair method, extending the life of concrete surfaces while restoring their functionality and appearance at a fraction of the cost of replacement.
Most polyurethane projects can be completed quickly and economically with minimal disruption, and are ready for use the same day. Ultimately, polyurethane leveling saves time, money, and disruption to businesses and homeowners.

Driveway Slab Leveling & Crack Repair
Driveways are an important part of your home or business – both in their function and how they act as a first impression to the rest of your property. Over time, moisture, elements, weight, and other factors cause your driveway to settle, crack, and become unlevel.
As your trusted and locally owned Seattle concrete repair specialist for multiple decades, we are the answer to repairs for your concrete driveway, including leveling, raising, and fixing cracks. Re-leveling large concrete slabs is much more cost-effective than replacement and doesn’t disrupt the surrounding landscape. Make the entrance to your home or business smoother and safer with slabjacking solutions and driveway leveling.
Concrete Leveling & Polyurethane Raising for Pool Decks
We specialize in repairs for unlevel, cracked, and sunken pool deck areas. Re-leveling large concrete slabs, such as those around a swimming pool, is a much more cost-effective foundation repair method than full concrete replacement and does not disrupt your pool. Making repairs like leveling out concrete and fixing cracks not only improves the look of your pool deck but also makes this area much safer for foot traffic – removing potential hazards for tripping and falling.
Concrete Leveling & Polyurethane Raising for Entries & Porches
In Seattle and Western Washington, settling of porches is common due to the effects of high rain totals and water. Settled and sunken porch slabs and steps are both dangerous and unsightly and invite nesting and burrowing from insects and small animals. R&R Foundation Repair and 1-866-SLABJACK provide concrete repair, leveling, and raising services for areas like porches and patios that may become sunken, cracked, and unlevel over time. Slabjacking brings your porch back to normal quickly and easily without expensive replacement. It is an effective, eco-friendly, and affordable alternative to replacing your entire porch area and can often be done in as little as a day.

Sidewalk Repair through Raising & Re-Leveling
Sunken cement sidewalks or roots pushing slabs up is our specialty to raise and repair through mudjacking or slabjacking. We repair and relevel city sidewalks often in Seattle, Tacoma, and many main street areas such as Bellingham, Kent, Bellevue, and Everett. Slabjacking corrects a wide range of sidewalk repairs, that involve pedestrian walkway hazards, quickly and neatly while removing safety and liability issues permanently.
We repair sidewalks that are older or brand new to raise them and level them through a process called mudjacking or poly level/polyurethane lifting. Both achieve the same results, but polyurethane material is lighter and resists water movement under the cement slab. If utilities are present under the sidewalks or the water table is causing the settling, lighter polyurethane is the best application to repair. Contact us and we are happy to provide a free assessment and recommend the very best material for your sidewalk repair project.
Frequently Asked Questions
What are the benefits of slabjacking?
The key benefits of slabjacking are:
- Cost – In most cases, the cost of raising a concrete slab using our service will be significantly cheaper than replacement. The average savings will typically be over 50% when compared to the expensive alternative.
- Minimal Disturbance – Our work is usually completed in one day or less, and the re-leveled concrete can be walked on immediately! Replacement requires demolition of the existing slab, formwork for the new slab, pouring, and time for curing. It is possible you may be without your driveway, walkway, porch, or garage for over two weeks if you choose replacement over re-leveling!
- The “Green” Choice – Our polyurethane material is made of recycled materials as well. Our process is simply replacing the soil which was either compacted or washed away. The alternative requires demolition of the existing slab, which will end up in a landfill or cost you more money to have it recycled.
- We can provide our service in nearly all weather conditions – We can perform slabjacking in the rain and in much colder temperatures than what is required for new concrete. Therefore, even in the fall and winter, we are able to handle all of your concrete leveling needs.
How do you raise concrete?
The process involves several steps and is simple in concept but very complex in equipment and technique. Our experts in the field will strategically drill holes through the existing concrete where voids have occurred beneath the slab, causing it to settle. Our polyurethane material is then pumped hydraulically beneath the slab. The injection of the material(s) will fill any remaining void and ultimately raise the concrete slab.
Approximately how much does this cost?
Unfortunately, the cost of our service is not easy to calculate due to the surrounding conditions, which cannot be determined prior to an on-site visit. This is why we provide a FREE on-site inspection. In most cases, the larger the concrete slab, the less expensive our service will be in comparison to the cost of replacement.
How do you address the cracks and condition of the existing concrete slab once it has been raised?
Our leveling service includes patching the holes drilled for the injection process. Once we have leveled the concrete, there are several options for repairing the existing cracks. We can repair just the cracks or provide different options for resurfacing the existing slabs. If you prefer, we can recommend different materials for you to install yourself as well.
We offer an additional service geared towards fine crack repair and color matching which compliments our sunken slab and broken driveway lifting process. Many times, cracks indicate settling, and once we correct the settled slab or cracked area, the additional service will fill the cracks through a tried-and-true expert repair process that matches exact stones for aggregate complexion and even the base cement color.
Our vendor will bring a kit with dozens of small aggregate rock colors and almost a dozen types of base cement sand that will match your existing concrete. This will ensure that after we correct any settling or broken driveway slabs, the repair is seamless! *Crack repair services are provided by our third-party vendor under a separate contract.
What kind of warranty do you offer for your service?
Warranties are provided on a case-by-case basis and are determined by conditions surrounding the concrete slabs. In most cases, our service is a permanent fix and never requires additional work. Please ask one of our estimators for more details while they’re on site to provide your free estimate.
What can you expect once our crew arrives at your home or business?
Our crew will bring their own equipment, contained in a truck or trailer with sufficient length of hose to accommodate your needs. The equipment remains parked while the polyurethane and poly lift crew pulls out enough hose to reach the area being repaired. Polyurethane foam, a high-density material, is injected under the slab filling voids and raising it to the correct level.
Customers can still access your main entrance, as our very courteous crew will ensure traffic flow is not interrupted.
Most jobs can be done in one day, though large jobs may take longer; your operations can continue while we work either way. Typically we can work around your stock or machinery, working with your schedule. Experienced crews have knowledge of the unique climate and soils throughout the Pacific Northwest region for polyurethane concrete raising in the PNW.
