TEKPAK® System

TWO PART SYSTEM. PUMPABLE CRIBS.

Tekpak® Pumpable Crib System has been specifically developed to provide enhanced standing and roof support in underground coal mining. Tekpak® is a two-part system consisting of Tekcem® and Tekbent®. Each component is a free flowing cementitious powder requiring only the addition of water in a suitable mixer to produce a consistent free flowing slurry. Each slurry has a 3 day pumping life. When mixed together the slurries react rapidly to provide a load bearing fill.

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.
