Concrete Slab Repair in West Jefferson, NC

Uneven concrete is dangerous for many reasons, and it allows water to pool in settling areas. An innovative concrete lifting and leveling solution is the best fix.



The patio entrance to a West Jefferson, NC, home had sunk over the last two years. The homeowners grew accustomed to the unlevel concrete and didn’t have a need to fix the problem. Unfortunately, water began pooling along the area affected the most by the settlement. This area was just outside the door, causing the homeowners to step in a puddle when entering or leaving the home after rainstorms.

After months of dealing with the problem, they researched a company that would provide them with an alternative solution to tearing out their entire patio. Tar Heel Basement Systems became their concrete repair contractor.

Certified Field Inspector Mike Jones recommended a solution that would meet the wants of the homeowners and the needs of the home. The patio would not need to be torn out and replaced. Fortunately, the PolyRenewal™ System would raise the sinking concrete slab, preventing the problem from recurring again with minimal disruption to the slab itself.

Because the patio was rather large, 29′ x 11′, penny-sized installation holes were strategically drilled every four feet in the slab. Unlike mudjacking which requires two-inch holes every two feet, PolyRenewal™ is much more discreet. Installation injection ports were placed in each hole, where the structural grade polymer was released. The expanding properties of the polyurethane allowed for the team to achieve stability and accurately lift the sinking slab back to the proper level using only 205 pounds of foam. The penny-sized holes were grouted over, making the system almost invisible. The waterproof foam will remain underneath the slab and intact for many years to come.

The PolyRenewal™ System was installed in a matter of hours, allowing the homeowners to walk along their patio just 15 minutes after the slab was raised. The homeowners are happy to have their patio restored efficiently and within their budget!
