5.04 Pumping Mortar

Rockbond 5.04 Pumping Mortar powder is a pre-mixed, ready to use mortar powder. The powder contains a blend of fine cement powders, graded quality sand and a union of admixtures.




5.04 Pumping Mortar, when mixed with water, produces a thixotropic, mortar which is specially formulated for the pumping, filling and sealing of voids in applications where a pumping grout of standard mortar isn’t an option.

It is ideally suited to ground anchoring applications where the ground is very weak or particularly dilated. The powder is packaged in 25kg durable bags, and has a shelf life of 2 years.
