Usage 

The Stratajack is placed in situ and extended to the correct height with compressed air. The product is then filled with Cougar Stratajacks cellular grout using a high capacity pumping system that has specifically been designed for use with the Stratajack.

The unique design of our product enables it to maintain a minimum 2000kg positive force between the roof and floor after the Stratajack is filled with grout and pumping has ceased.

The Stratajack is able to be installed to suit the underground conditions. With the ability to adjust the MPa of the cellular grout used to fill the Stratajack to meet the peak load requirements for each installation site.
