ROCK BOND IS A TSL

THAT PREVENTS OXIDATION AND WEATHERING OF PROBLEMATIC ROCK AND ALSO KEY BLOCK INTERLOCKS YOUR EXCAVATIONS FOR LONG TERM MINING.
Rock Bond is an innovative, spray-applied Thin Support Liner (TSL) designed specifically for the mining industry. Its primary function is to create a protective coating that prevents oxidation and weathering, which can weaken and deteriorate exposed rock surfaces over time.

support Seriously!

Rock Bond is an effective solution for extending the lifespan and reliability

of mining excavations, ensuring a secure working environment by both preventing surface decay and fortifying the natural rock architecture.

In addition to shielding against environmental degradation, Rock Bond also plays a crucial role in stabilizing excavations by reinforcing key block interlocks. This interlocking mechanism enhances the stability of rock formations, providing long-term support to excavation sites and reducing the likelihood of collapses. This feature is essential for maintaining the structural safety of underground mining operations, as it supports the alignment and cohesion of rock masses in complex geological conditions.

BENEFITS OF ROCK BOND

Rapid application and less material per square.

Quick application with high areal coverage enables early reaction against ground movement. Key blocks are maintained in place from an early stage helping the rock support itself. One of the main advantages of Tunnel Guard SS is the speed of application, especially where limited face time is available in the case of multi-blast conditions. Less material is used with the advantage of reducing your shaft time and transport costs.
