Although expandable rock bolts are very effective in protecting tunnel shafts and underground mine galleries, they are also expensive to install, take up valuable space and are difficult to remove.

If you want to secure your tunnel or mine gallery and use space efficiently, expandable rock bolts are not the best option.

With our boltless rock bolt system, you get the same level of protection while saving precious budget and space. Our system eliminates the need for installing bolts — instead, all you need is a drill machine and a few bolts to make your tunnel or mine gallery secure.
