FREQUENTLY ASKED QUESTIONS

Concrete raising with polyurethane foam is a cost-effective alternative to replacing concrete. The total cost depends on factors such as the size of the voids, the extent of the slab’s settlement, and whether other sections need repairs. To ensure transparency, PURLIFT® offers a FREE on-site assessment. One of our expert estimators will evaluate your project and provide a detailed estimate—no surprises or hidden costs.

After assessing your project and providing an estimate, work typically begins within 2 to 4 weeks once the proposal is accepted. Most jobs are completed in just a few hours. You can drive over the repaired slabs immediately, but we recommend waiting 24 hours before parking heavy vehicles on them.

For polyurethane concrete raising, small 5/8" holes are strategically drilled approximately 5 feet apart in the affected area. Thanks to the efficiency of polyurethane foam, fewer holes are required compared to traditional mudjacking, minimizing disruption and leaving a cleaner finish.

We use PolyLEVEL®, a premium expansive polyurethane foam injected as a liquid, which expands and sets into a rigid, durable material. This foam is lightweight, resistant to shrinking, and maintains its density over time. It requires fewer and smaller holes than traditional methods, providing an effective and nearly invisible repair.

No. The foam is fed through a hose connected to our truck or trailer, eliminating the need to drive heavy equipment onto your lawn. We ensure the surrounding area is protected during the injection process.

Upon completion of the job, the small holes are patched with cement for a seamless finish. While the area is ready for use almost immediately, we recommend allowing a few hours for the patch material to fully set before use.

To maintain your repaired concrete and prevent future sinking, we recommend the following:

• Seal the cracks and joints with a self-leveling silicone caulk available at home improvement stores. Purlift® also offers this service.

• Ensure proper drainage by directing downspouts and runoff away from the repaired area.

• Backfill against the edge of the slab using garden soil to ensure that water does not seep underneath the slab.
  

These steps are essential to preserving your repair and are a condition of your PURLIFT® warranty.

We can lift and stabilize solid concrete slabs, but gravel areas, blacktop, or severely damaged concrete may require replacement .

Raising your concrete is often less than half the cost of replacing it, with less disruption to your landscaping and faster results.
