ClosureTurf®

Product Overview

ClosureTurf® is a patented final cover system comprising AGRU’s Super Gripnet® or MicroSpike® geomembrane overlain by an engineered synthetic turf and specified infill material. It is a proven “hybrid” composite closure system that outperforms earlier closure methodologies and is the only system that provides a predictable level of performance when subjected to severe weather conditions that occur in a post-closure timeframe. Based on several years of real-world experience on over 900 acres of installation, and extensive university and ASTM lab evaluations, the ClosureTurf system has shown to have a leakage rate over 40 times less than Subtitle D prescriptive and an erosion loss of over 100 times less than subtitle D prescriptive cover.

ClosureTurf is an EPA Subtitle-D and Federal CCR Rule-compliant final cover system that can be installed more than 50% faster than traditional closure systems, which utilize cover soil materials. ClosureTurf eliminates the need for large quantities of soil and related equipment usage, cost, borrow pit and hauling operations, thus dramatically improving site safety and decreasing its carbon footprint by almost 80%.

ClosureTurf reduces average maintenance costs by approximately 90% per acre per year. This final cover system also dramatically improves runoff water quality, making it an effective tool for best management practice in relation to Clean Water Act requirements.

Benefits of ClosureTurf®

  • Removes 2’ – 3’ of cover soil required for early industry closure methods
  • Delivers superior/predictable performance and aesthetics, even when exposed to severe weather events during post-closure
  • Removes additional geotechnical loading above the closure by eliminating cover soil materials
  • Improves stability, erosion protection, emissions control and leachate reduction – even on very steep slopes (2:1 or steeper)
  • Lowers annual operation and maintenance costs
  • Clean stormwater runoff
  • Rapid closure for odor control and gas management
  • Reduces construction carbon footprint by up to 80%
