Mining & Tunnelling
The Australian mining and tunnelling sectors operate in some of the world's most challenging geological conditions. MACT provides a suite of robust, reliable, and safety-focused chemical solutions designed to enhance ground stability, ensure operational efficiency, and protect critical infrastructure.
Ground Support & Strata Control
Effective ground support is paramount for safety and productivity. MACT offers high-performance products for immediate and long-term strata control:
- Thin Spray Liners (TSLs): Our MACT TSL range (including TSL-Flex and TSL-Std) provides rapid, flexible, and durable surface support, sealing fractured rock and preventing weathering, particularly crucial in improving safety and ventilation control.
- Shotcretes: The MACT Shotcrete-Series, including our innovative MACT Shotcrete-SF (Silica-Free), delivers high-strength primary and secondary support for tunnels, declines, and stopes. Options include high-performance mixes and fibre reinforcement for enhanced toughness.
- Anchor Grouts: Secure rock bolts and cable anchors effectively with our MACT Anchor Grouts (AG-TD and AG-BU). Formulated for thixotropic or high-flow applications, they ensure complete encapsulation and rapid strength gain for reliable anchoring.
Void Filling & Water Control
Managing voids and water ingress is critical for stability and safety. Our specialized grouts offer effective solutions:
- High Yield Grouts: The MACT HYG range (HYG-Fill and HYG-Foam) provides lightweight, high-yield solutions for filling large voids, cavities, and behind tunnel linings, improving ground consolidation and preventing subsidence. Foaming options are available for specific applications.
Infrastructure Maintenance & Repair
Maintaining site infrastructure is essential for continuous operations. MACT provides rapid solutions for critical repairs:
- Rapid Road Repair: MACT RapidRoad, a silica-free binder, enables extremely fast repairs to haul roads, hardstands, and access ways, minimizing downtime even in damp conditions.
Safety Focus
Worker safety is a priority. MACT is committed to developing safer alternatives, exemplified by our silica-free products like MACT Shotcrete-SF and MACT RapidRoad, which significantly reduce the risk associated with crystalline silica exposure in confined underground environments.
