Tunnel Guard

Tunnel Guard is a thin cementitious spray on liner that provides robust structural secondary support and consolidates various problematic rock types.

Tunnel Guard penetrates deep into the rock mass along open fractures and joints, acting as a hard rough gouge that fills and increases the cohesion across the fractures.

This strengthens the rock mass and limits the ability of the rock fabric to move. (Key Block-Interlocking) Tunnel Guard also seals the rock; preventing oxidation and weathering, thus preserving your excavations for long term mining.

Tunnel Guard is non-toxic, non-flammable and environment friendly.
