AGRU America offers industry-leading geosynthetics specially designed for the closure and containment of coal combustion residuals (CCR). AGRU is one of the largest producers of CCR solutions, with solutions designed to tackle sectors such as mining, solid waste disposal, and industrial manufacturing. AGRU’s array of solutions are designed to meet even the most stringent project parameters.
The EPA’s ruling on the disposal of coal combustion residuals has defined the standard for successful containment and closure of CCR facilities. Since then, AGRU has been committed to becoming the supplier of choice CCR closure solutions. AGRU provides some of the most innovative and versatile options in the industry. AGRU’s line of solutions include traditional geosynthetics, polymer-enhanced GCL’s, Integrated Drainage System (IDS) geomembranes, white geomembranes, and the ClosureTurf® Impoundment and Landfill Closure System.

CCR Closure Solutions
A patented final cover system comprising AGRU’s Super Gripnet® overlain by engineered synthetic turf infilled with sand. It is a proven “hybrid” composite system that outperforms traditional closure methodologies. ClosureTurf is an EPA Subtitle-D compliant final cover system that can be installed more than 50% faster than traditional closure systems. ClosureTurf 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.
Integrated Drainage System (IDS)
Integrated Drainage System features an AGRU structured geomembrane, Super Gripnet or MicroDrain® liner, overlain with an AGRUTex® geotextile. Simply place soil on top of the geotextile to complete the system. The greatest performing and most versatile of the traditional methods, the IDS system can feature an aggressive texturing on the underside of the Super Gripnet geomembrane providing unmatched shear strength and stability even on steepened slope applications.
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.
CCR Containment Options
Integrated Drainage System can feature structured geomembranes such as AGRU’s Super Gripnet or MicroDrain Liner overlain with an AGRUTex geotextile. Simply place soil on top of the geotextile to complete the system. The greatest performing, and most versatile of the traditional methods, the IDS system can feature an aggressive texturing on the underside of the Super Gripnet geomembrane providing unmatched shear strength and stability even on steepened slope applications.
AGRUTex is a 100% polypropylene (PP) 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. AGRUTex geotextile is resistant to ultraviolet degradation and to biological and chemical compounds normally found in soils. AGRUTex extends the life of a project by protecting other critical materials from puncture, migration, or degradation.
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.
