MACT TSL-Std (General Purpose TSL)
Target Audience: Mine Managers, Civil Contractors, Project Engineers seeking a cost-effective, reliable TSL for general surface sealing and weathering protection.
Cost-Effective, Single-Component Thin Sprayed Liner for Reliable Surface Sealing - Just Add Water
Overview
MACT TSL-Std is a pre-blended, single-component (add water only) cementitious Thin Sprayed Liner offering a practical and economical solution for general-purpose surface sealing and strata protection in mining and civil applications. It provides good adhesion (>0.8 MPa) and durability (>25 MPa at 28d), effectively preventing weathering and reducing air loss. Its simple, add-water-only formulation streamlines logistics and on-site mixing, making it ideal for projects requiring reliable performance without the need for specialized polymer components.
Key Technical Advantages
- Simplified Logistics: Single-component, pre-packaged powder – just add potable water on site.
- Reliable Performance: Provides effective adhesion (>0.8 MPa) and durable surface protection (>25 MPa compressive strength).
- Effective Sealing: Creates a competent barrier against air ingress/egress and prevents strata degradation due to weathering.
- Versatile Application: Suitable for both dry and wet spray application methods using standard equipment.
- Cost-Effective Solution: Delivers dependable TSL performance for budget-sensitive projects.
