ClosureTurf Cross Section Illustration

As a response to numerous failures and poor performance of environmental closures at landfills, engineers have studied new approaches to establish a more physically stable and environmentally sound solution. Traditional landfills require large amounts of soil throughout their lifespan and are often lacking adequate soil to complete closure construction. Many of these landfills experience on-going erosion and sedimentation issues. Traditional covers are highly reliant on trucking soils, heavy civil construction, on-going maintenance and repairs in order to maintain their integrity.

Introducing ClosureTurf™, an EPA, Subtitle D Compliant landfill closure solution that is specifically designed to address and solve soil erosion, slope integrity, gas emission, installation and maintenance cost control, EPA regulation compliance, and longevity of structure and appearance.

ClosureTurfTM is a patented, three component system comprised of a structured geomembrane, an engineered turf, and a specialized sand infill. The foundation of the system is an impermeable, highly transmissive structured geomembrane. It provides for the highest interface friction values available in the market. The engineered turf component gives the system its natural look and feel of grass while protecting the geomembrane from extreme weather conditions for the long term. The specialized sand infill component is placed between the blades of the engineered turf and allows the system to be trafficked while also providing additional protection from weathering. When required, ClosureTurf’s patented surficial gas system is included with the system to vent landfill gas emissions. ClosureTurf is fast and easy to install for an aesthetically pleasing, cost-effective landfill closure solution.

ClosureTurf prevents these common failures:

Gas System Failure

gas system failure

Reduces and sometimes eliminates the need for traditional gas wells or piping

Erosion Failure

Eliminates 99.9% of sediment runoff versus traditional practices

Slope Failure

slope failure

Eliminating thick soil profiles over the geosynthetics provides greater stability on steeper grades and reduces slope rebuilding
