Concrete Leveling FAQ

No. PolyLevel is a proprietary product developed by Supportworks and is available exclusively from LRE Foundation Repair and other concrete repair contractors in the Supportworks network.

PolyLevel® is designed to provide long-lasting, even permanent stability, as long as the soil beneath the concrete remains stable. Once injected, it expands to fill voids and support the slab, locking it in place.  As long as external factors—like erosion or poor drainage—don’t impact the underlying soil, your concrete should stay level for years to come.

LRE offers a 3-year warranty on all concrete leveling projects completed using PolyLevel®, ensuring your repair is backed by durable materials and expert workmanship.

If you choose our complete concrete protection system, which includes lifting and leveling with PolyLevel®, crack and joint sealing with NexusPro®, you’ll receive an extended 5-year warranty for added peace of mind and longer-lasting results.

PolyLevel® cures very quickly. In fact, you can drive your car over a driveway slab just 15 minutes after it's been lifted with PolyLevel.

We use a great product called PolyLevel® to lift and level sinking concrete. PolyLevel® comes with many advantages over the traditional mudjacking and concrete replacement options.

Yes—PolyLevel® is engineered to be a permanent solution for sinking and uneven concrete. This high-density polyurethane foam expands beneath the surface to lift and level slabs, fill voids, and strengthen weak soil. Once cured, it forms a solid, stable base that won’t wash away, break down, or be affected by moisture or UV rays.

Because PolyLevel® bonds with the soil and supports the concrete from below, it delivers long-term results you can count on. And for added peace of mind, LRE backs every PolyLevel® project with a 3-year warranty, so you’re covered if the unexpected happens.

Yes. PolyLevel is made from an environmentally friendly material that is waterproof and won't degrade over time. This means it won't leach harmful chemicals into the surrounding soil.

PolyLevel® is cost-effective because it offers a long-lasting solution, unlike mudjacking and slab replacement. And your concrete will never cost less to repair than it does right now.

Concrete problems are common, and all concrete can fail at some point. Concrete slabs are heavy! When concrete is poured on top of soil, it runs the risk of sinking.

When the soils underneath a concrete slab are unable to support its weight, the slab will sink.

There are several reasons why concrete sinks:

• Lack of Slab Support: If part of the concrete slab is supported by soils and other sections of the slab are not, the unsupported pieces may slip away from the other sections of the slab and result in unlevel concrete, cracking, and crumbling.
• Soil Shrinkage & Compaction: Soil shrinkage, compaction, and settling all have an impact on sinking concrete. If the soil beneath the slab is not compact, the concrete can easily begin to sink as the soil beneath it solidifies and hardens. If the soil is too wet or too dry, this can also cause concrete to sink.
• Types of Soil: Different types of soil have different load-bearing capabilities. When a soil's load-bearing capacity is exceeded by the weight of the heavy concrete on top of it, the soil will compact and settle, causing the concrete to sink, crack, crumble, and become uneven.
• Soil Washout: As water moves underneath your concrete slabs, it can wash away the soil that's supporting the weight of the concrete, creating a void or empty space below. Over time, the slab can begin to sink.

At LRE, we back our concrete repair work with industry-leading warranties—a 3-year warranty with PolyLevel® alone, or a 5-year warranty when combined with our full concrete protection system, including crack and joint sealing with NexusPro®.

If your concrete settles again during your warranty period, we’ll inspect the area and address the issue at no cost to you. Ongoing settlement may indicate deeper soil movement or drainage problems, and if that’s the case, we’ll recommend the best long-term fix to keep your concrete safe and stable. Our goal is to give you lasting peace of mind and a repair that holds up over time.

PolyLevel® is a high-density polyurethane foam that is lightweight and durable, developed by our provider Supportworks, and available solely through a select network of foundation and concrete repair contractors. This modern technology surpasses traditional mudjacking by using polyurethane foam instead of a mud-cement mixture to lift and level uneven concrete driveways. Unlike mudjacking, which involves a messy and disruptive installation process requiring larger ports, PolyLevel® offers a cleaner solution. Furthermore, mudjacking often fails to address the core issue of soil stability. As concrete driveways sink and crack due to soil movement, such as expansion, contraction, and erosion, mudjacking can make matters worse by adding additional weight to unstable ground, which can lead to further voids. 

In comparison, PolyLevel® is waterproof, ensuring it will not wash away or deteriorate over time. During the installation process, the expanding foam not only elevates the concrete slabs but also compresses the surrounding soil, increasing stability and reducing the chances of future settling and sinking.
