Fill Voids Under Concrete

Do you have a concrete driveway, patio or foundation that is sinking due to voids in the soil underneath the slabs? Our team at Advance Concrete Lifting and Leveling can fill those voids and gaps under your concrete with a durable polyurethane foam that will provide support and protection for decades. Our method is quick and reliable for lifting and leveling most types of concrete slabs that are settling due to erosion.

Our method of slab jacking uses a special polyurethane foam that is injected underneath concrete slabs. This works great for concrete slabs that have lost support and have begun to sink or settle. We drill small holes into the concrete to pump polyurethane foam under the concrete slab. The foam expands and becomes harder, lifting the concrete slab as it fills voids in the ground where soil was lost. It cures in about 15-30 minutes and can last for decades. The layer of foam binds to the soil and helps prevent further erosion and gaps to protect the concrete from future settling or sinking.

What Causes Gaps Under Concrete?

Erosion is the most common reason soil is displaced under concrete slabs. The granules of soil can move, especially with water intrusion. Heavy rains or flooding are common causes of water soil erosion. A burst water or sewer line can also erode soil under a foundation, driveway, sidewalk or patio, creating voids under the concrete. Slab jacking using polymer injections is a quick and lasting solution to repair and fill these gaps, extending the life of your concrete surfaces and supports.
