Advantages of High-Density Polyurethane
High-density polyurethane concrete leveling has many advantages over other concrete leveling/lifting methods.
- More Economical
Provides a permanent solution that's 75% cheaper than the cost of removing and replacing existing concrete. No future repairs are needed.
Over 80% faster than alternative methods of repair. Material hardens in minutes allowing the project to be completed in hours versus the days or weeks that other methods require.
Polyurethane foam to creates its own hydraulic lift so we can control the lifting process precisely to within 10/1000th of an inch. Other methods must account for shrinkage of material by over-lifting the area, polyurethane will never shrink.
Due to the fast curing time of high-density polyurethane, traffic control can be removed and lanes reopened to traffic immediately after the injection process. Nighttime scheduling lessens delays and inconveniences.
Polyurethane’s compressive strength provides a solid and dense product yet its tensile strength and elongation allows for the material to be pliable allowing it to permanently support the roadway structure by being tough yet forgiving.
By expanding 20 times its liquid volume, polyurethane foam material moves laterally beneath the pavement filling all voids. Additionally, it perfectly contours to the size and shape of the voids to fully completely support the pavement with 100% coverage.
An additional benefit during the lifting process is the compaction of base soils through the resistance of lifting the concrete structure. The material bleeds into the sub base and binds soil particles together strengthening the base material.
Polyurethane only adds 3-5 pounds per cubic foot to the sub base compared to the 100 pounds plus that mudjacking grout adds.
Better Structural Integrity
To help maintain structural integrity of the concrete pavement injection holes are only 5/8" in diameter versus 3" or larger for other concrete lifting methods.
Our specially formulated polyurethane material is designed for wet conditions. It’s hydrophobic properties displace and repel water without being compromised and replaces any missing sub base with a solid/dense material unaffected by moisture.
Moisture Seal Barrier
Polyurethane seals the underside of concrete pavement joints and cracks to eliminate water penetration and erosion issues.
Puts counties, cities and municipalities in control of their aging infrastructure by saving them time and money.
High-density polyurethane can be used to level many applications, such as parking lots, streets, basement slabs, and apartment concrete floors. To view a full list of applications, click here.
