Job Summaries From Grand Island, NE
PolyLevel Makes a Safe Driveway For Grand Island Homeowner

Dean E., a policeman in Grand Island had a driveway made up of six concrete panels.  One of the panels closest to the garage had a large crack in it and was starting to settle causing a 2 inch ledge.  Being a policeman he knew of the legal actions that would be taken against him if someone fell and got injured due to the gap.  He knew something had to be done ASAP to fix it. After a quick search online he knew who to call, the professionals at Thrasher Basement Systems. 

Not too long after the call, specialist Brian Marron was out to Dean's home to inspect the driveway.  The solution he close was quick and simple.  This was to have foreman Collin Crouch come out and to lift the slab back up with the PolyLevel system.  This is done by drilling small (penny sized) holes in the slab using specially designed equipment to inject a structural grade polymer into the void. After the void is filled, the expanding properties of the polyurethane allows for an accurate lift and leveling of the slab.

Dean no longer has the worry of others or himself falling and getting hurt all thanks to this simple system by Thrasher Basement Systems!
