How much does concrete raising cost?

Concrete slabjacking using polyurethane foam is more cost-effective than installing new concrete. Ultimately, the cost of raising or stabilizing concrete is a direct reflection of how much material the project will require. The cost of the repair depends on a few factors: the size of the void to be filled, how far the slab is settled, the amount of voids to be filled, or if other sections need to be involved in the repair. To avoid any unexpected costs, simply call a PURLIFT estimator who will assess your project on-site and provide a FREE estimate before the work begins.


How long will it take to get my work done?

At your request, our estimator will assess the project and provide an estimate of the work to be repaired. Provided the area is accessible, it is not necessary to be present at the time of the estimate. Once the proposal is accepted and signed, work can usually begin within 2 to 4 weeks. Jobs typically take only a few hours to complete. Slabs can be driven over once the job is completed, but we suggest that you wait 24 hours before parking on the slabs.


How many holes will there be?

On the day of your work, holes (5/8") are strategically drilled every 3 to 5 feet in the settled area. Fewer holes are typically drilled for polyurethane applications. Holes are necessary to lift slabs, drilling holes cannot be avoided.


What kind of material do you use?

PolyLeveling MaterialsPolyurethane material is injected as a liquid that sets as a rigid foam. The foam will NEVER lose density or shrink. This material is lighter than traditional mudjacking material and requires fewer holes to install. Even better, the holes are smaller, creating a virtually invisible repair!


Will there be heavy trucks on my lawn?

Heavy Truck Off DrivewayThe polyurethane used to repair your concrete is fed through a hose brought from the truck/trailer to the site. We will never drive equipment on your lawn.


How do you fill the holes?

Once the concrete is raised, holes are patched with cement. The concrete is ready for use immediately; however, we recommend that you allow the patch material to set for a few hours before using the area.


Is there any maintenance required?

Once the work is completed, it is the homeowner's responsibility to caulk the seams of the sections that were repaired, or backfill against any exposed areas to contain the material and prevent future sinking. Self-leveling cement caulk can be purchased at any home improvement store and works great for sealing joints. Using a silicone-based, pourable self-leveling caulk is recommended. If a crack is large, you can use less material by putting sand down before caulking the top. Preventing water from going under the slab is fundamental to preserving the repaired slab. Make sure that your downspouts are correctly placed to assure water runs away from your concrete slabs or foundation. Taking these suggested steps for preserving your raised concrete is a condition of your PURLIFT warranty.


What can be raised?

Solid slabs of concrete can be raised and stabilized. Gravel areas or blacktop cannot be repaired by way of polyurethane concrete raising and need to be replaced and reinstalled to remedy settling issues. Slabs of concrete that are too badly cracked may also be too far damaged to lift. If you are not sure whether your concrete can be raised, call PURLIFT for a FREE ESTIMATE. Raising settled concrete can be half the cost of replacing it, with less damage to your landscaping and less downtime for you.
