PCC Joint & Crack Sealing

PCC Joint & Crack Sealing is most effective when performed before your concrete is deteriorated. When the existing sealant is no longer functional, Denco has over three decades of experience sawing, preparing and sealing joints and random cracks in PCC pavement.

Full-Depth Concrete Patching

Rehabilitate spalling, scaling, joint deterioration, and punchouts in your roads with full-depth patching from Denco Highway. PCC patching follows a process of locating and removing damaged areas, preparing the patch area by compacting or replacing the subbase and reinforcing with steel, and, finally, placing, finishing, and curing new PCC.

The Denco crew restores trouble areas that pose hazards and inconvenience to your county drivers. We take pride in the strength, finish, and ride of our full-depth patches.

Mudjacking & Pressure Grouting

Address the settled bridge approaches and concrete slabs in your county with pressure grouting and mudjacking from Denco. Pressure grouting lifts sunken PCC to level with the surrounding pavement by pumping grout into the soil below the existing structure to stabilize the earth beneath.This process diverts water flow from eroding concrete over time.

Denco’s unique process involves special attention to soil stabilization through an effective form of compaction grouting to maximize the effectiveness and durability of the job. Contact us to set up an on-site evaluation and discover the best solution for your location.
