ProRise geotechnical polyurethane foams are ideal choices for making
repairs to sunken or misaligned concrete slab sections around
residences and structures. Sunken or misaligned sidewalk sections,
foundations, patios, concrete steps and driveways can be repaired in
most cases by injecting ProRise under the concrete to raise and level it to
its original position, possibly avoiding costly tear-out and concrete
replacement.
