CJGrout 20SDB
CJGrout 20SDB is a very high mobility 2.0lb/cuft free rise density two-part polyurethane grout system formulated for lightweight fills, undersealing and bulk void filling below and adjacent to structures. CJGrout 20SDB’s high degree of flow and low exotherm facilitate work around delicate structures and mass placements.
It was first developed for backgrouting the Pinkerton Tunnel, in Somerset, Pennsylvania. Since then, this CJGrout system 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. Other projects include:
- filling 3′ deep voids under a floor in Manhattan, NYC
- backgrouting 14′ diameter CMP culverts in Asheville, NC
- mass lightweight fill under I-395 in Arlington, VA
Typical Uses
- Spray/pour in place mass lightweight fills
- Filling large voids under and adjacent to floors, drainage structures and buildings
- Bulk grouting of sinkholes
Physical Properties
With a bearing capacity of 4.4KSF, this grout is well-suited for use under light to moderate loads. The free rise density is 2.1lb/cuft.
