Slabjacking: Can It Fix Your Sunken Concrete Driveway?

Posted on

If portions of your concrete driveway appear sunken or broken, consider slabjacking it. Slabjacking not only repairs your driveway; the technique strengthens and supports it. Learn more about slabjacking and how it can lift, repair, and support your driveway below.

What's Slabjacking?

Concrete can potentially settle, crack, or sink into the ground over time. The damage causes voids to form between the slab and soil. Water can gradually fill in the voids and weaken the slab and soil supporting it. Slabjacking is one of the methods used to repair and lift damaged concrete slabs.

Slabjacking requires contractors to inject grout or another type of filler beneath sunken or damaged concrete. Grout contains materials that bond or blend naturally with concrete. Once grout dries, it forms a solid base between the slab and ground. The base keeps the slab from sinking further into the ground.

Slabjacking isn't something you want to do yourself. You want to hire a concrete contractor instead.

Who Can Lift Up Your Driveway?

Although slabjacking may seem simple, it isn't. The technique involves a number of important things you may or may not know about, including where and how to insert the grout in your driveway. A contractor can complete the job for you properly.

The first thing a contractor may do is check the condition of your driveway. If your driveway requires extensive work, a contractor may suggest you upgrade it. Fillers may not enough to support and repair your driveway. If slabjacking is the best option for you, a contractor will use it to lift your driveway.

A contractor will generally need to drill holes in your driveway before they apply the filler. The holes may be anywhere from 1 1/2 inches to 2 inches deep, depending on how thick your concrete driveway is at the time. A contractor will use the holes as access points for the filler.

A contractor may also consider a few other things during the repairs, including the following:

  • location of your driveway
  • size of your driveway
  • age of your driveway

If your driveway sits near water sprinklers, a contractor may need to use extra grout to keep the concrete safe from moisture. If your driveway is long or old, a contractor may reinforce the structure with beams and other types of lifts. The concrete may require extra support to keep it properly raised in the future.
