Problem
Gamber & Community Fire Company’s outdoor carnival stage was sinking
in due to the settlement of the soils beneath. The concrete stage
had begun to crack and cave inward with 5” voids below. This resulted
in a hazard to the community, department, and band members. The
stage needed to be repaired before the carnival to allow for safe usage
of the main event stage. The department wanted to save time and
money in repairs by avoiding the need to demo three walls, the roof, and
the concrete stage.
Solution
Foam Solutions Inc. proposed concrete raising as a solution to raise
and level the stage. FSI injected polyurethane foam into the 30’ x 15’
stage using incremental injections of foam. FSI was able to fill the large
voids completely beneath the slab before raising, leveling, and stabilizing
the slab permanently.
Summary
Gamber & Community Fire Co. Chief reached out with concerns about
the structural integrity of the concrete stage. With the summer carnival
approaching, it was important to make the repairs in a timely matter.
Additionally, being a volunteer fire company, it was as important to
make a budget-friendly repair. FSI was able to raise, level, & stabilize
the stage utilizing polyurethane foam injection. This repair method eliminated
the need to demo the walls, roof, and stage. Work was completed
in one day before the carnival season approached.
