The Compak provides an economic solution to stope and gully support requirements.
- The Compak retains its structural integrity and provides energy absorption characteristics during seismic events.
- The Compak is easy to construct due to its interlocking design.
- The Compak prevents fines entrapment due to its “closed face” configuration.
- The Compak provides a high ignition resistance, emits no noxious fumes, and is self-extinguishing once heat source is removed.
- The Compak provides efficient shaft utilisation characteristics due to their compact transport volumes.
- The Compak can be designed to meet any support or rock condition parameters.
- The Compak may be erected in different configurations, to accommodate the yield and safety requirements of different mines.

Pre-stressing Composite Packs
- Active pre-load can be applied to the Compak units using Lokpak non-weeping grout, and Novax or Blokpak weeping grout, pre-stressing systems.
- Pre-stressing will prevent the blasting out of Compak units within minutes of pre-stressing.
Compaks have been subjected to the CSIR Fire Tests, and have been proven to resist propagation of fire.
Timber materials may deteriorate due to weathering, allowing the timber to dry out. Technicrete applies FIFO principles. Every effort is made to minimise storage periods.
The use of personal protective equipment is mandatory. The weight of individual Composite Pack units should not lead to any physical injuries, should the correct handling procedures be followed.
