Sunken Slabs Create Trip Hazards
One of the first reasons a sunken slab is often noticed is because it’s created a trip hazard. The Americans with Disabilities Act (ADA) defines a “trip hazard” as any vertical change over a ¼ inch or more at any joint or crack. Cities, school districts, hospitals, churches, shopping malls, universities, apartment complexes, homeowner associations, large buildings, and private residences should all be concerned with this liability.
Concrete Leveling with Polyurethane
Eliminating these hazards and avoiding litigation is as simple as hiring a contractor who is using the right concrete leveling technique and material. Ground Consolidation Services lifts and levels slabs using Alchemy-Spetec’s line of AP Lift products. These high-density polyurethane lifting foams are used in a wide array of applications from lifting walkways to lifting highway bridge approach slabs on DOT projects.
Slab Lifting vs Slab Replacement
In addition, GCS has specialized tools in our bag like the jack system we use to mechanically manipulate the smaller, harder-to-control slabs. The only other viable option to lifting the slabs, in most cases, is the removal and replacement of them. This option is generally much more expensive and certainly more time-consuming and intrusive. We often do jobs for customers who have gone that route in the past and every single time they say they wish they had known that GCS was an option. We are usually done within a few hours, with the treated areas being traffic ready immediately.
