This privately owned building was constructed inside of the basement of a previous building, but with a smaller footprint. Structural slabs were poured spanning between 4′ and 20′ from the original basement walls to the new basement walls.
As the structural slabs over the unused basement deteriorated, there were concerns about stability. Uses included a public sidewalk and parking/driveway area. The wall isolating the occupied space of the new building and the unoccupied area of basement was constructed of hollow clay block, metal studs & drywall. The maximum lateral load of any backfill material could only be 50PSF.
CJGeo successfully filled the basement with 775CY of CJFill-UL7.5. The placements was done in 2′ lifts to meet the maximum 50PSF liquid head limit.
