Our Tekpak® S two-component grout is the ideal product where the long distance pumping of high volume grouts is required. Mixed as two separate components which are pumped to the application site and then mixed together, Tekpak® S reduces the impact of dust on operating areas of your mine.
Tekpak® S is a versatile product, able to be used for a variety of different applications including:
Pumpable at over 3000 m, Tekpak® S is able to complete an entire longwall block of Pumpable Cribs and goaf seals from the one location. Its fast set time and rapid strength gain ensure that Tekpak® S applications are reaching their required performance within your time frame.

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.
Minova's Tekpak® P 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® P and Tekbent® which when mixed together rapidly reacts to produce a load bearing crib. Tekcem® P is a blended cementitous powder which forms an easy to pump slurry when mixed with water, remaining pumpable for 24 hours. Tekbent® is a low viscosity non setting liquid with an indefinite pumping life.
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.
