Technical Mastery at Mining Scale
In mining, performance is measured by durability under load and precision over millions of square feet. SAI operates as an extension of your engineering team, specializing in the installation of the most demanding geosynthetic barriers. We execute projects involving steep slopes and extreme chemical environments.
Our commitment ensures:
Heap Leach Pads
The base of a modern Heap Leach Pad is the most critical civil element of any mine. SAI specializes in the certified installation of textured HDPE composite liner systems engineered to withstand massive ore loads and highly aggressive chemical solutions. Our focus on slope stability, high-quality seam welding, and integrated drainage layers ensures reliable fluid collection, maximizing mineral recovery and operational life.
Friction Angle and Stability
Proven field experience installing textured geomembranes on critical slopes to ensure the highest interface friction for ore heap stability.
Solutions Ponds
Safe and effective containment of leach solution (PLS), raffinate, and process water is essential for environmental compliance and operational safety. We install primary and secondary containment systems using chemically compatible materials (HDPE, LLDPE, or specialty liners) designed for extreme chemical resistance and long-term durability, minimizing evaporation and maximizing the integrity of your process fluids.
Chemical Resistance
Installation of chemically-compatible liners (HDPE or specialty material like XR-5) for leach solution ponds with typical pH ranges of 0.5 to 2.0 for copper leaching.
Dual Containment and Leak Detection
Expertise in installing both primary and secondary geomembrane liners, including integration with leak detection systems and sump designs.
Need an immediate geomembrane liner repair? Contact us, we'd be happy to help!
We give new life to a damaged liner and put it back into compliance. Let us worry about the repairs.
Tailing Dams
Tailing dams require the industry's most robust containment and water management plans. SAI provides certified installation of extensive, multi-layered geosynthetic barrier systems designed to prevent the migration of mining residuals. Our expertise in high-volume drainage, integrated GCLs, and final capping ensures compliance with stringent environmental regulations and provides long-term structural integrity for closure.
