Tunnel Guard, a Thin Sprayed Liner (Super Skin),
was developed by South African Mining &
Engineering Supplies in 1994. It is used as a
support element to seal and consolidate various
problematic rock types and prevent oxidation of
the rock in standard and high-risk areas.
Primary benefits of the product are its
durability, ease and speed of application.
Sprayed Liners (Super Skins) are widely used because
they work often when no other means of support is
available. In large part this is because they can be
applied rapidly and safely, reinforcing the rock mass in
the early stages before it moves too far down the ground
