Rockbond Underwater Grout (RB UWG) and Concrete (RB UWC)
Product Information Sheet:
Description
ROCKBOND UNDERWATER GROUT (RB UWG) powder is a premixed cementitious grout powder specially formulated for underwater applications. The compound contains a blend of cement powders, high quality graded sands and a union of admixtures. The grout powder, when mixed with water, produces a material that is cohesive, mobile, self compacting and displays excellent resistance to washout when brought into contact with water. ROCKBOND UNDERWATER CONCRETE (RB UWC) has similar properties to the grout, but the material contains an aggregate and is applied to fill larger volume voids. The powders are packaged in 25kg moisture proof durable bags and have a shelf life of 2 years.
