Pavement Stabilization

Thrasher Commercial offers affordable, permanent repairs for all sunken concrete problems. When a concrete surface is no longer providing safe, solid support due to settlement issues, prompt action is necessary before the problem gets worse. Before you demolish the concrete slab, consider the advantages of PolyLevel® or Low-Density Cellular Concrete (LDCC). These are lower cost alternatives to common concrete remediation methods like mudjacking, concrete grinding, or total concrete replacement. 

Advantages of PolyLevel®:

• Lightweight –Weighs approximately 4 pounds per cubic foot- almost no additional load to supporting soils.
• High Capacity – Lift action is a result of the expansion of the foam, allowing for much larger loads 
• Accurate Lift – Calculated reaction time of polyurethane foam allows for precise lifting
• Waterproof – It is hydrophobic and can be used to under-seal the slab and stop other infrastructure leaks
• Quick Cure Time – Allows for even heavy traffic just 15 minutes after completion of the injection of the material

Advantages of Low-Density Cellular Concrete:

• Low-density - By controlling the foaming action, it’s possible to create densities ranging from 15 to 120 lbs. per cubic foot
• Excellent pumping qualities - thanks to its high air content and low density, cellular concrete is easy to pump – even over long distances 
• Light and durable - Cellular concrete is typically stronger than compacted fills or soils, even at its lower densities.
• Permeable or non-permeable - Can be formulated to stop water penetration or allows it to drain through the material.  
• Self-leveling - Excellent flow characteristics. It performs well at filling voids and flowing to form a level surface.
• Insulating - Captured air bubbles give the material much better insulating qualities than other masonry materials.

One example of a dramatic pavement repair using PolyLevel and low-density cellular concrete was a Void Fill on Q Street.

In this case study, Thrasher Commercial was called in by Douglas County, NE engineers. They were scrambling to find a solution for four large voids, caused by flooding of the Elkhorn River in Western Douglas County. The flooding washed away chunks of the street and the sub-base that supported a 2-year-old bridge. Read the full Case Study here. The Thrasher crew used more than 200 yards of LDCC, taking just 2 days to complete the job. They delivered on time and under budget, so that evacuation and rescue transportation could continue.
