Basement & Radon Solutions, BRS Pros used our Poly Fill to lift the sidewalk that had sunk. Here are some steps taken to help and some benefits:1.We started by drilling holes in strategic spots on the sidewalk. They were drilled in the affected areas of the concrete. Usually in a regular pattern and spacing to allow for even pumping of concrete raising material underneath.2. Polyurethane foam is pumped in – with the holes in the slab, polyurethane foam is pumped in with the use of a high-pressure injection gun. The material instantaneously expands and fills the voids underneath the slab and in the soil, raising the concrete to its original level. This material also helps stabilize the soil underneath by filling in the gaps and compressing loose areas.3. Cost Effective – Concrete raising is typically half the cost of replacing the same concrete. Ultimately, the cost of raising or stabilizing concrete is a direct reflection of how much leveling material the project will require.4. Quick-Cure Time – Polyurethane typically cures 15 minutes after injection allowing areas to be fully available in minutes instead of days.5. Clean Work Environment – No concrete or grout spatter and no wash-down needed.6. Small Holes – Polyurethane concrete raising creates nearly invisible 5/8 holes with minimal patchwork required.7. Lightweight – Weighing only 2-4lbs per cubic foot, high density polyurethane’s lightweight characteristics will not overburden the soil.8. Green! – The poly foams we use are environmentally friendly, consisting of 39-49% renewable and recycled materials that are made in the USA. Most poly raw materials are petroleum-based. Our green polyurethane Bio based materials are also good for the environment.It was a pleasure helping Donna make her sidewalk safe again! “
