Rappass offers high performance, abrasion resistance and rapid strength. Rappass C, a special concrete mix requires the addition of water to produce a flowing concrete consistency. Rappass GD is a specially blended cement that is applied by dry shotcrete processes. Uses include lining ore passes, outfalls, spill ways, draw points, crushers and chutes.

Supplied as a pre-packaged coarse dry powder in 20kg bags. Sprayed with the addition of water using dry shotcrete process. Sprayplast can also be used for scat control and ventilation control.
Cement based spray material designed with excellent flexibility, high tensile strength and excellent adhesion qualities. Tekflex powder is added to Tekflex liquid through a specially designed pump system for a continuous mixing and spraying operation.
Used to permanently stabilise the integrity of rock structures while accommodating the stresses associated with strata movement and providing a barrier to moisture degradation. Tekflex was developed for specific use as an alternative to the use of steel mesh for scat control in underground mining excavations.
