Rachelle L. In Johnston, Iowa noticed that her driveway, sidewalk and steps were sinking. The sinking slabs created trip hazards, and we a pain to shovel snow off from. Using polyurethane foam injection, we filled voids beneath the driveway concrete slabs to lift and level them. We also sealed any cracks and joints with NexusPro to protect the concrete from water intrusion and erosion that might cause sinking in the future.
Before - Sinking slabs and exposed joints
The walkway slabs between the driveway and the house entrance were uneven and had unsealed joints, allowing water to penetrate beneath the slab where it can erode the supporting soil.

After - Curb appeal
Unsealed concrete joints allow weeds to grow up between the slabs, spoiling the appearance of a home. Sealed joints not only help prevent concrete sinking, but also looks great!
