What Is Slabjacking?


Slabjacking is the process of injecting polyurethane (poly) beneath a sunken slab to "float" it back. Slabjack examples are an uneven sidewalk that needs repair or a driveway that needs leveling. We use a specialized Poly lift material that corrects settlement issues and sinking without the cost and hassle of replacing concrete slabs.

Why Choose Slabjack?


For decades, we've been the cement and concrete leveling company people trust in every neighborhood. We have a keen understanding of the Puget Sound climate and its effect on concrete and cement sinking and settling, helping people improve the safety and appearance of many areas of their homes.

Driveways

Re-leveling large concrete driveway 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.

Basement Floors

Slabjacking is ideal for leveling basement floors where access is often limited. It’s simple, clean, and usually completed in less than a day. Our equipment connects to injection ports through small drilled holes, which means no excavation, no heavy machinery inside the home, and no major demolition.

The Best Concrete Crack Repair

Fine crack repair and color matching complement our sunken slab and broken driveway lifting process. Once we correct the slab or the cracked area, we can fill the cracks using a tried-and-true expert repair process that matches the cement's color and texture.

Polyurethane Concrete Raising

This is a cost-effective alternative for leveling concrete surfaces, which avoids replacement and can usually be done for less than half the cost of pouring new concrete. It achieves the same results, and the surface can typically be used the same day.
