Pumped Lightweight Fill

CJGrout-20SDB is low speed, low exotherm polyurethane formulated for high mobility, mass void filling applications.  It was first developed for backgrouting the Pinkerton Tunnel, in Somerset, Pennsylvania. Since then, 20SDB has proven to be an incredibly versatile high mobility grout for use in applications from factory floor undersealing to lightweight mass pit fills at a chemical manufacturing facility in Wilmington, Delaware.
