CASE STUDY: Gamber & Community Fire Company - Sunken & Unstable Concrete Outdoor Stage



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

E&F Contracting, inc. proposed concrete raising as a solution to raise

and level the stage. E&F injected polyurethane foam into the 30’ x 15’

stage using incremental injections of foam. E&F was able to fill the large

voids completely beneath the slab before raising, leveling, and stabilizing

the slab permanently.
