RB 5.03HF Pumping Grout HF

Rockbond Pumping Grout HF (RB 5.03HF) is a premixed blend of fine cement powders, specialist admixtures and a shrinkage compensating additive.

The powder, when mixed with water and pumped under pressure, is particularly flowing and penetrating.

RB 5.03HF is specially formulated for the filling and sealing of voids in concrete and rock, and can be pumped over large distances.

Rockbond Pumping Grout HF Accelerated contains chloride free accelerators, and is used during winter weather work, or when a rapid early strength gain is required at 20ºC.
