How Polyurethane Concrete Lifting Works

Lift Sunken Concrete Without Expensive Replacement

Polyurethane concrete lifting, also known as polyjacking, polyurethane foam injection or concrete slab leveling, is a proven method for restoring sunken concrete without the expense, mess, and downtime of complete concrete replacement. Whether you have a sunken patio, uneven sidewalk, settled driveway, garage floor, or basement floor, polyurethane concrete lifting provides a fast, precise, and long-lasting solution.

Every project begins with a thorough inspection of your concrete to determine why the slab has settled and identify the areas that require lifting. Over time, soil erosion, poor compaction, expanding and contracting soils, moisture, or natural settlement can create voids beneath concrete slabs. These empty spaces cause uneven concrete, sinking concrete, and dangerous trip hazards.

Once the affected areas have been identified, our technicians drill a series of small, strategically placed holes through the concrete. These holes are typically only about the size of a dime, making the repair minimally invasive and preserving the appearance of your existing concrete.

Next, a specialized high-density polyurethane foam is injected beneath the slab. As the two-part polyurethane material expands, it fills empty voids beneath the concrete, stabilizes weak soil, and gently lifts the slab back toward its original position. Throughout the lifting process, each adjustment is carefully monitored to ensure precise results and prevent over-lifting. This level of control allows us to accurately level driveways, sidewalks, patios, garage floors, basement floors, pool decks, walkways, and other concrete slabs.

Once the concrete has been properly lifted and stabilized, the injection holes are professionally patched with a cement-based material that blends with the surrounding concrete. The polyurethane foam cures quickly, allowing most repaired surfaces to be used shortly after the repair is completed. Unlike traditional mudjacking, polyurethane foam is lightweight, water-resistant, durable, and designed to provide long-lasting support beneath the concrete.

Polyurethane concrete lifting is an excellent solution for homeowners looking to repair uneven concrete, eliminate trip hazards, improve drainage, restore curb appeal, and extend the life of existing concrete. In many cases, concrete lifting and concrete leveling cost significantly less than replacing an entire slab while providing exceptional long-term performance.

Whether you need patio leveling, sidewalk leveling, driveway lifting, garage floor leveling, or basement slab leveling in Denver, Littleton, Lakewood, Highlands Ranch, Centennial, Parker, Castle Rock, or the surrounding Colorado communities, polyurethane concrete lifting is one of the most effective and cost-efficient methods available for restoring settled concrete.
