A concrete surface, such as a patio or driveway, can sink if the slab was installed incorrectly or if soil erosion has occurred. In this case, slabjacking is an effective solution that will prevent the need for a total replacement. If you’re currently considering your concrete repair options, this guide goes over a few of the basics so you can make an informed decision. 

A Guide to Concrete Slabjacking

How does this process work?

First, contractors will drill holes into the concrete. One or two holes may suffice for smaller slabs, but large installations can require three or more. They will then pump materials—such as limestone, grout, or polyurethane foam—into the holes that will spread under the concrete to help raise it.

As the pumping material hardens, it creates a sturdy base under the surface to prevent future issues. After, the holes are cleaned and patched.

How are the holes patched?

When foam is used to raise concrete, patching is not necessary since the foam will fill in the holes on its own. When other materials are used, the holes can be filled in with mortar, which dries to become stiff and durable. The final step involves covering the holes with cement to create a uniform look across the concrete surface. 

Can all sagging concrete installations be repaired using this method?

Numerous fractures in the concrete slab typically can’t be addressed via slabjacking. The process is also not recommended for sinking slabs under immense structures. In that case, the fill material may not be strong enough to provide the necessary support. 

What are the benefits of slabjacking over concrete replacement?

Total concrete replacement is usually much more expensive than raising the slab. Slabjacking is also more aesthetically pleasing since it won't involve laying down new concrete, which will be a different color than the other sections.

People may also walk on the surface as soon as slabjacking is complete. Contractors recommend that people do not park their cars on a new concrete driveway for 10 days after installation.
