CASE STUDY: Carroll County Public Schools - Sidewalk Trip Hazards


Sidewalks on the perimeter of the county schools’ parking lots had

E&F Contracting, Inc injected polyurethane foam beneath the existing

sidewalk slabs. E&F was able to raise, level, and stabilize the sidewalks

without the need for demolition and replacement at four county

schools so far this season. E&F provided a cost-effective solution that

completed in 1-2 days at each school and foam injection was able to

system being on a strict budget, E&F’s method of raising and leveling

their concrete sidewalks saved them approximately 70% of the cost of
