Penefil - Concrete Lifting

Over time, building foundations settle, house patios erode, roadways shift and sink which inevitably requires either costly replacement or structural repair beneath the concrete slab. Penefil Ò provides an easy solution by injecting high-density, polyurethane polymer into holes drilled through the slab into the subgrade. This quickly expanding hydrophobic foam fills voids, stabilizes soft soil and raises the concrete foundation. The Penefil material can be dispensed evenly and precisely by professionals across the entire slab to raise and to level the existing concrete, while mitigating erosion damage.

Concrete lifting may be used on all types of cement work, such as driveways and sidewalks, factory floors, patios, parking facilities, residential slabs and pool surrounds.
