Save your concrete; Save your money



Often, concrete slabs, surfaces or structures become unlevel and damaged due to failure of the substrate beneath. This means the dirt under the concrete has eroded and simply worn away, leaving a void. The concrete lacks support, so it sags into this void, causing cracks and other damage. Replacing the concrete would also necessitate filling in the void, adding to your repair costs.

Concrete void filling with polyurethane foam is a much better solution. Inline Concrete can inject our Foamjection liquid foam deep underneath your concrete to fill voids and provide the necessary stabilization. The foam expands before it becomes solid, adding erosion control measures as well as the vital support to lift and hold the concrete.

Filling the void underneath the concrete lifts and levels the structure, adding stabilization that will not deteriorate or erode. And there is no messy, destructive process. Your existing concrete is preserved, and we only need to drill a few small holes, which are filled after the job is complete. Concrete void filling is much faster and far cheaper than replacing your concrete and adding fill dirt.
