What are the Solutions for an Uneven Driveway?

There are, broadly speaking, two main solutions for an uneven, sinking, or damaged driveway that focus on repairing the existing surface rather than replacing it entirely. They are mudjacking and polyurethane foam injection. 

Polyurethane Foam Injection 

If the soil under your driveway or sidewalk is already struggling to deal with the weight being placed on it, or it is prone to shifting and moving when weather is bad, PolyRenewal foam injection is one of the best possible solutions. PolyRenewal polyurethane foam will be the best solution for your property and situation for a number of reasons. You see, unlike concrete slurry, this foam is incredibly lightweight, water-resistant, and quick setting. 

Despite this, PolyRenewal foam is incredibly effective! The expansive force created by the two-part foam is remarkably strong and will lift the concrete slabs or surface back into place with relative ease. Once in place, the stable, water-proof, and inert foam will prevent the damage from recurring in future. This makes PolyRenewal far preferable to concrete replacement.

Installing PolyRenewal

Before PolyRenewal can be installed holes will be drilled into the damaged concrete surface to allow for foam insertion. These holes will then be fitted with injection ports to create a seal during installation. This will prevent foam from escaping and causing a mess. The polyurethane foam itself will then be mixed from two parts. This allows us to tailor the expansive force and the level of expansion to your needs. 

The foam is then injected into the cavity where it will quickly expand, lift the surface of the driveway or sidewalk, and set to 90% of its full hardness within an hour. This makes the process far less disruptive and far more accessible. The cost of this process is slightly higher, but we feel that it is well worth the investment.
