Mining Applications and Product Solutions from AGRU


Application Overview

Modern technology depends on extracting valuable elements such as lithium, magnesium, and cobalt from mining. Precious metals such as gold, silver, and copper are equally important. Whether operating an evaporation pond or heap-leaching ore, AGRU America has you covered.

AGRU geosynthetics are utilized throughout many mining operations, serving as the base liner system in tailings storage facilities (TSF), heap leach pads (HLP), ponds, and channels and for HLP, TSF, and waste rock closures. AGRU pipes, fittings, concrete protective liners, and other products can also help support more efficient mining operations.

AGRU America offers exceptional protection quality and turnaround, competitive freight costs, and fast delivery times with production plants throughout the United States.

AGRU Smooth Liner®

Tough and flexible, HDPE and LLDPE AGRU Smooth Liner is the material of choice for containment applications. The chemically resistant material provides consistent thickness and delivers optimum weld speed and weld quality in the field. All AGRU Smooth Liner material is rolled on 23’ wide plastic cores to ensure ease of installation, eliminating the problem of collapsed cores.

MicroSpike® Liner

As the only HDPE and LLDPE geomembrane featuring consistent texture and friction angle values, MicroSpike is the material of choice in containment applications where slope stability is critical. AGRU’s patented manufacturing process, flat die-cast extrusion, allows the company to produce the most consistent smooth or textured geomembranes.

Black & White Liner

Black & White geomembranes offer the advantages of both a light reflective white surface and a black damage detection layer. The liner’s ultraviolet (UV) resistant white surface reflects light, which minimizes associated heat absorption by as much as 50%, while the black HDPE lining geomembranes can reach temperatures of 160°F (71°C) or more.

Super Gripnet® Liner

Comes in two resin types, HDPE and LLDPE, to support projects where drainage and high interface friction, as well as cost savings, are critical. Examples include landfill caps, landfill slopes, and mining reclamation projects. Super Gripnet is a structured geomembranes that is manufactured by a continuous horizontal flat die extrusion into profile rollers, which give the product the final structured surface with drainage studs and spikes that are an integral part of the liner.

AGRU Drain Liner®

A geomembrane available in two resin types: HDPE and LLDPE. AGRU Drain Liner is best suited for single- or double-lined projects such as landfills, waste ponds, lagoons, mining heap leach pads, and process ponds where containment and leak detection is crucial. AGRU Drain Liner eliminates the need for a separate geonet or geomembrane drainage layer, providing cost savings in material usage and installation.

ClosureTurf®, a Watershed Geo patented product, is a three-component system comprising a structured geomembrane, an engineered turf, and a specialized sand infill. The structured geomembrane comprises either AGRU’s SUPER GRIPNET® or MICROSPIKE® geomembrane. This final cover system is EPA Subtitle-D compliant and installs more than 50% faster than traditional closure systems. It also eliminates the need for large quantities of soil and related equipment usage, dramatically improving site safety and decreasing its carbon footprint by almost 80%. Reduced soil and equipment usage also leads to lower construction costs.

A 100% polypropylene nonwoven geotextile that lowers initial project costs by reducing the amount of base material needed. This needle-punched staple fiber geotextile membrane is ideal for environmental and civil engineering applications including cushioning, separation, stabilization, and filtration. Extends the life of a project by protecting other critical materials from puncture, migration, or degradation.

AGRU Geocomposite

AGRU Geocomposite Closure System is the traditional method for closures, which utilizes AGRU MicroSpike or AGRU Smooth Liner geomembrane, overlain by a geocomposite drainage layer, soil cover layer, and vegetative layer. This traditional closure system utilizes a cost-saving geocomposite drainage layer. It also offers the highest and most consistent asperity height available on the market, providing consistent and dependable shear strengths.

AGRU Geonet

A high-density polyethylene liner that is ideal for applications such as landfill cells, leak location in double-lined systems, landfill caps for drainage and methane gas collection, and landscape drainage systems. AGRU’s Geonet is bixial and biplanar, presenting a rib formation that allows for high flow in both machine and cross machine directions.

AGRU GeoClay®

A reinforced needle-punched geosynthetic clay liner that comprises a uniform layer of granular bentonite that is encapsulated between a woven and a nonwoven geotextile, or between two nonwoven geotextiles. These products are intended for moderate to steep slopes and moderate- to high-load applications, where increased internal shear strength is required.
