Rotafix Underwater Mortar

Rotafix Under Water Mortar is a polymer modified cementitious mortar that is capable of curing under water.

Rotafix Underwater (applied) Mortar

Rotafix Under Water Mortar powder is a blend of special cement powders, high quality graded sand, and a unique combination of polymers and admixtures. The powder, when mixed with water, produces a mortar which is wash-out resistant and waterproof. 

The ready to use mortar powders are packaged in 25kg moisture proof durable bags and have a shelf life of 2 years.

By using pre-mixed bags you will get a consistent formulation just by adding a consistent amount of water. Alternative products where admixtures are supplied separately will give inconsistent and variable results.
