Composite Packs provide an economic solution to stop and gully support requirements.
Advantages
- Composite Packs are easy to construct due to the interlocking characteristics.
- Composite Packs prevent fines entrapment in the body of the pack.
- Composite Packs have a high ignition resistance, no noxious fume emissions, with self-extinguishing characteristics, once the heat source is removed.
- Composite Packs improve shaft utilisation due to their compact transport volumes.
- Composite Packs can be designed to meet any support or rock condition requirements.
- Composite Packs are available in different configurations to meet all the yield and safety requirements of different mines.
- Composite Packs have had a long track record.

Performance

 |
Pre-stressing Composite Packs
- Active pre-load can be applied to the Composite Pack using Lokpak non-weeping grout, and Novax or Blokpak weeping grout, pre-stressing systems.
- Pre-stressing will prevent the blasting out of Composite Packs within minutes of pre-stressing.
Fire Resistance
Composite Packs have been subjected to the CSIR Fire Tests, and have been proven to resist propagation of fire.
Storage
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.
Safety
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.
