The Cookiepak provides an economic solution to low stoping and gully support requirements.
Advantages
- The Cookiepak retains its structural integrity and provides energy absorption characteristics during seismic events.
- The Cookiepak is easy to construct due to its modular design.
- The Cookiepak prevents fines entrapment due to its ‘closed face’ configuration.
- The Cookiepak provides a high ignition resistance, emits no noxious fumes, and exhibits self-extinguishing characteristics, once the heat source is removed.
- The Cookiepak is designed to support low stoping widths and is available in a “L” configuration for interlocking in long axis gully packs.

Pre-stressing Composite Packs
- Active pre-load can be applied to the Cookiepak using Lokpak non-weeping grout, and Novax or Blokpak weeping grout, pre-stressing systems.
- Pre-stressing will prevent the blasting out of Cookiepaks within minutes of pre-stressing.
Fire Resistance
Cookiepaks 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.
