Overview
Geosynthetic drainage layers – geocomposite or geonet materials have been used to replace the more expensive soil/aggregate drainage layers of earlier design methods. While these materials provide superior performance and cost savings compared with the natural soil/aggregate materials, they introduce challenges from an interface friction, specification conformance, and installation perspective. Agru has addressed these challenges by producing the Integrated Drainage System – IDS, a Subtitle D-compliant closure and containment system that incorporates an advanced drainage structure within the geomembrane component. By combining multiple layers—each with its unique benefits—into one product, AGRU provides a powerful closure and containment solution that also delivers significant cost savings.
With lower material, shipping, and installation costs, IDS can be a much more economical option for closure systems than conventional geomembrane/drainage composites. All AGRU geomembrane products are available in two high-quality resin types: high-density polyethylene – HDPE or linear low-density polyethylene – LLDPE. AGRU geomembranes meet and exceed all GRI GM 13 – HDPE and GRI GM 17 – LLDPE test values.
Technical Aspects
Applications
- Closure Solution
IDS is an ideal closure solution for landfills as it can be configured based on the project specifications. The configuration will depend largely on the steepness of the slope of the closure area. For example, base applications make use of MicroDrain liner, whereas the steepest slopes benefit from AGRU Super Gripnet Liner’s spike height. - Containment
IDS is an excellent performing and cost savings containment solution for double-lined ponds, reservoirs, pits, and containment cells because it can be configured based on the project specifications. The IDS configuration will depend largely on the steepness of the slope of the containment area and normal load above the system.
IDS benefits
- Incorporates drainage and environmental containment performance into a single layer
- Reduced need for separate drainage material layers, representing substantial cost savings and avoids material delay associated with geocomposites
- The HDPE portion of the liner has a thickness of 50 mil, which is 25% thicker than the 40 mil requirement for membrane closure systems.
- Requires a lower number of rolls to ship, unload, and store on-site.
- Installs 15% faster when compared to the traditional closure system
- High factor of safety for steep-slope stability.
IDS Component Specifications
IDS is a customizable system with several component options for each layer depending on the specific requirements of the project.
AGRUTex®
AGRUTex is a nonwoven geotextile product line is specifically designed for waste containment applications providing filtration, separation, and/or protection for other geosynthetics. Geotextiles help to ensure the long-term viability of waste storage units. Used in a wide variety of construction projects, AGRUTex is easy to install and has a track record of high performance.
AGRU Drain Liner®
Drain Liner comprises upward-facing drainage studs with consistent pattern and spacing, delivering high flow rates and reliable drain capacity. These built-in studs eliminate the need for a separate geonet or geocomposite drainage layer, providing cost savings in material reduction and installation.
AGRU Smooth Liner®
Smooth Liner is ideal for any application that requires a tough and flexible barrier, minimal interface friction performance, a broad range of chemical resistance and capable of delivering high performance over the project’s lifetime.
AGRU MicroDrain® Liner
MicroDrain geomembrane comprises upward-facing studs with consistent pattern and spacing, delivering high flow rates and reliable drain capacity. The bottom-facing portion of the liner is textured to improve slope stability, made with AGRU MicroSpike Liner.
AGRU MicroSpike® Liner
MicroSpike Liner features consistent texture and friction angle values, making it the material of choice in containment applications where slope stability is essential. To create MicroSpike, AGRU uses the patented manufacturing process called flat die-cast extrusion.
AGRU Super Gripnet® Liner
Super Gripnet Liner comprises upward-facing studs with consistent pattern and spacing, delivering high flow rates and reliable drain capacity. The bottom-facing portion of the liner has spikes for a high-friction surface that delivers superior slope performance.
