A general contractor working for a school district in Buffalo, New York was asked to lift and level around 550 feet of sidewalk slabs at a local high school. The general contractor called in slab lifting specialists Gernatt Spray Foam to get the job done. Since sunken slabs often result in trip hazards, getting the job done quickly and permanently was a top priority.

Powerful Polymer

The slab lifting crew showed up on the scene armed with AP Lift 435 high-strength polyurethane and several Jack Attack devices.

Painless Procedure

Gernatt Spray Foam leveled all 550 feet of sunken sidewalk slabs with total precision. They performed lifts ranging from 0.5 to 6 inches, depending on the slab. In some cases, they lifted with polyurethane only and in others, they raised the slab with the jacking devices before injecting the polyurethane underneath.

Rapid Result

The entire job was completed in only two days. The general contractor and school administrators were both amazed at the efficiency and surgical precision of the polyurethane slab lifting method.
