Virginia Beach, Virginia -- Concrete Jack's crews are on standby to use high density polyurethane injection and lightweight cellular concrete to pump these waterproof void-filling materials under undermined structures as a result of Hurricane Sandy.
The company points out that tidal inundations and storm surges frequently wash backfill material out from under interior floors of homes and businesses, boat ramps, pool decks and other structures that are flooded.
Injection of high-density polyurethane and cellular concrete fill in voids under undermined structures can resupport the structure, allowing it to return to use immediately, Concrete Jack said in a press release.
Both high density polyurethane and lightweight cellular concrete are typically used in industrial processes to resupport unsound concrete and other structures, such as bridge approaches, roadways, interior slab floors and concrete parking lots. However, they are excellent for void filling under residential structures too, since voids from tidal inundation are usually deep and extensive.
Concrete Jack is based in Williamsburg, Virginia, and serves Virginia, North Carolina, Maryland, Washington DC, West Virginia and Pennsylvania.
The company's crews install lightweight cellular concrete, high-density polyurethane and sand-based grout, typically referred to as slabjacking. Concrete Jack's experienced crews have installed high-density polyurethane (foam jacking), lightweight cellular concrete and sand-based grout (slabjacking) under numerous structures as a result of flooding washing away original backfill material.
