Say Goodbye to Mudjacking and Hello to PolyRenewal®

In the past, Atlanta concrete leveling and repair contractors relied upon mudjacking (also known as slab jacking, grout pumping, and slab leveling) to level concrete that had settled over time. This entailed pumping grout or heavy concrete slurry under the settled slab to raise it and hope the settlement wouldn’t continue in future years or even months.

At AquaGuard, we use PolylRenewal, a polyurethane foam that is a simple, quick, and highly effective way to fix sunken, cracked, or uneven concrete surfaces.

How PolyRenewal® Works for Concrete Repair

Developed by Groundworks, PolyRenewal polyurethane foam is a custom formulation created exclusively for a network of concrete contractors across the United States. PolyRenewal is a strong, yet incredibly lightweight polyurethane solution that will not add weight to the existing soil. 

PolyRenewal moves like water as it fills even the smallest cracks and crevices in the soil. As it quickly expands and hardens, PolyRenewal lifts the concrete slab above and compresses the soil around it, all at the same time.

What is Causing My Concrete to Settle?

There are many factors that can cause concrete settlement; however, there are three main reasons why concrete slab begins to settle:

Soil Washout

Water caused by plumbing leaks, heavy rainfalls, and erosion can find its way underneath your concrete slab. As the water moves, it can wash away the soil that is supporting the heavy weight of your concrete. The foundation can begin to sink and settle due to the soil being too moist.

Badly Compacted Fill Soil

When new homes or commercial buildings are being constructed, builders add layers of soil to the foundation to ensure the desired grade level. If a new slab is being poured on top of this loosely compacted soil, the chances of your concrete settling are more likely to occur.

Changes in Soil Moisture

Your soil can either become too wet or too dry. If your home was constructed with soils that are higher in clay content, they will most likely shrink as they become too dry. When shrinking occurs, it causes the creation of empty space underneath your concrete slab, resulting in uneven and cracked concrete. However, if your soil is too moist, it won’t be able to hold the weight of your structure, causing your foundation to sink and settle.

Sinking concrete can be especially troublesome if you are:

  • Preparing your home for sale 
  • Concerned about the liability of visitors tripping on your property
  • Simply want to enjoy your home with family and friends
