Tekpak® Pumpable Crib System has been specifically developed to provide enhanced standing and roof support in underground coal mining and offers substantial benefits in terms of roof control, speed and ease of installation. Tekpak P is a two part chemical system consisting of Tekcem and Tekbent which when mixed together rapidly reacts to produce a load bearing crib. Tekcem is a non-combustible brown blended cement powder which forms an easy to pump slurry with water. Tekbent is a non-combustible low viscosity non setting liquid. Tekbent has an indefinite pumping life and Tekcem is pumpable for at least 24 hours.
The system provides a more productive means to install roof support in longwall mining operations, providing increased safety for operational personnel and more cost effective mine production.

Two component grouting resin for cable bolt anchoring and self drilling bolts. An instantly thickening, fast curing, two component silicate resin for high strength bonding of solid bolts and cable anchors. The final mixture thickens very quickly to form a tough, interpenetrating non porous elastic silicate. This minimises leakage from the bolt hole, displacing drilling water helping ensure full encapsulation.
Carbothix has been designed especially for use with our range of UniPass dynamic and static rock bolts. Tested in Australian conditions, Carbothix allows for improved rock bolting productivity.
Fast setting, low viscosity grout used for fall recoveries. Supplied as a ready to use free flowing blended cementitious powder. It requires only the addition of water in a suitable placing machine.
Uses include backfilling behind steel sets, replacement for timber chocks in longwall tailgates and recovery of falls in headings and intersections.
Our FB200 low viscosity, high yield grout is used for many applications within underground mines. We have 20 years experience in using FB200 for stabilising rockfill to enhance stope extraction, constructing explosion rated ventilation seals, filling of large voids and constructing false pillars for pre-driven recovery roads.
We have developed variants for hostile conditions such as saline water, hot water and long distance pumping.
Typically pumped at a 2:1 water:powder ratio, FB200 can be used between 1:1 and 3:1 ratios depending on individual project requirements.
FB200 is supplied as a ready to use free flowing blended cementitious powder that only requires the addition of water in a suitable placing machine.
