Landfill Closure Application | AGRU

Landfill Closure

Application Overview

Landfill containment is a complicated business. Regulations, leachate and gas production, elevated temperatures, chemical reactions, and liner degradation are considerations that engineers must make when designing a landfill containment system. Add to that the complexity of closure and post-closure care, and it becomes clear why new and better solutions are needed.

One of the most important steps when installing a new landfill or final cover system is selecting a manufacturer. The manufacturer must also adhere to best practices or industry norms, which exist after years of trial and error. These practices can ensure your project’s success and impact your bottom line.

AGRU offers a variety of innovative closure product solutions to solve some of the toughest waste containment problems. From traditional closure systems to AGRU’s Integrated Drainage System (IDS) and ClosureTurf®, AGRU solutions are compliant with the EPA’s Subtitle D-related requirements for Impoundment and Landfill Closure Systems. Additionally, AGRU offers state-of-the-art solutions to streamline installation, manage drainage, combat erosion, and more.

Closure Solutions


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.

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 Geocomposites

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.

AGRUTex Geotextiles

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.

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.
