Cracked and sinking concrete steps are more than a cosmetic issue or tripping hazard. The real issue is the soil underneath your steps, which can settle, erode, or shrink over time and threaten your home’s structural stability.

We recommend our SettleStop™ PolyRenewal™ polyurethane injections, which compress soil and lift and level your steps. Learn more about this concrete lifting technique below.

What Is Concrete Crack Repair?

Groundworks tech repairing cracked concrete on driveway

Your concrete slabs might crack and sink when the soil underneath settles, erodes, or shrinks due to poor compaction, inadequate drainage, or over-drying. The right concrete crack repair solutions, like PolyRenewal™, address this damage and restore your slabs to their original condition.

PolyRenewal™ consists of a commercial-grade expanding polyurethane foam, which is more effective for concrete repair than filling cracks with caulk. It potentially lifts settled sections of concrete and seals and removes visible cracks. As a result, you can ensure the appearance and safety of your slabs for years to come.

Signs Your Home Needs Concrete Crack Repair

Various concrete surfaces can develop cracks, including:

We recommend a concrete crack repair solution if you notice any of the following problem signs:

  • Visible and expanding crackswider than ¼”
  • Uneven or sinking concrete slabs
  • Tripping hazards
  • Cracked walls or damaged siding above sunken concrete
  • Crumbling edges
  • Pitting, flaking, and staining
  • Pooling water after rain
  • Weed growth between sections of concrete

Is Concrete Crack Repair Necessary?

Early repair of cracked concrete can avoid additional damage and expensive repairs. However, so-called DIY “solutions” only provide a temporary fix and won’t solve the soil problem that caused cracking and sinking in the first place.

PolyRenewal™, on the other hand, tackles the underlying cause of cracked concrete by stabilizing soil and stopping washout. 

Advantages of Concrete Crack Repair

Repairing cracked concrete provides the following benefits:

  • Improve Safety: Levelling uneven, sunken concrete and sealing up cracks prevents trips and falls.
  • Stop Further Deterioration: Injecting expanding foam under unstable concrete slabs stabilizes the ground, halting settlement and other damage.
  • Increase Property Aesthetics and Value: Cracked concrete detracts from your property’s appearance and worth. PolyRenewal™ makes your slabs look as good as new.
  • Extend Your Concrete’s Longevity: Slight cracks can soon turn into major repairs. Concrete lifting and stabilization solutions enhance the strength and integrity of your slabs, meaning you don’t need to replace them.

  • Waiting for the foam to swell, which raises the concrete slabs
  • Allowing around 15 minutes for the foam to solidify
  • Removing the injection ports before closing and refining the drilled openings

Concrete Crack Repair FAQs

We’ll drill a small hole through your concrete slabs into the soil underneath before injecting our high-density polyurethane foam. This fills cracks, compresses the soil, and potentially stabilizes and lifts your slabs. We then fill the holes with cement.

Cracks wider than ¼” require immediate attention, so contact the professionals at Groundworks for a free inspection of your concrete slabs. PolyRenewal™ can lift, stabilize, and seal cracked concrete, preventing further damage.

It depends on the extent of the concrete damage and the number of slabs. When we inspect your property, we’ll provide a free price estimate.

The work done promptly by Ryan and his team (Eryica, Ny) was excellent with the driveway lift that was extremely necessary. The team did a great job being on time and within the time allotted to complete the work. Would recommend to others if they need a professional job done while being efficient. Thank you again!

We got 3 quotes for driveway lifting. These guys were competitively priced and had good reviews on google so we hired them. I’m glad we did! They were very friendly, professional, and efficient. They did a great job and cleaned up afterwards. When James and his partner came back to seal the joints, the service was just as good as the first team. Thanks again!

They showed up, gave me quote on the spot, I approved it they showed up next day and got it all done in 4 hrs. Evan zack and trevor were great to deal with during the install and gave me a walk thru when it was all done letting me know all the details of the job. Would recommend 👌

He was very easy to deal with and most importantly, we never felt pressure during the whole quoting process.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.
