RB 4.04 Underwater Concrete

Rockbond Underwater Concrete (RB 4.04) is a premixed cementitious micro concrete specially formulated for underwater and tidal zone applications. Rockbond Underwater Concrete contains a blend of cement powders, high quality graded sands, an aggregate and a union of admixtures. The micro concrete, 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. This product has similar properties to Rockbond Underwater Grout (RB 4.03), but the material contains a rock aggregate and is applied to fill larger volume voids and horizontal/angled surfaces that require a layer that is 60mm or greater.

Supplied in 25kg tri-wall plastic lined paper bags.
