Louisa County Landfill Artificial Turf Closure
When it came time for Louisa County to construct a final closure cap on their 14-acre, unlined sanitary landfill, they turned to LaBella’s Waste & Recycling team (Joyce Engineering, at the time) for options and analysis. Our evaluation considered many factors, including gas and leachate control, groundwater and drainage, erosion and resulting maintenance, and initial and long-term costs.

Louisa County Landfill Artificial Turf Closure
The County ultimately chose ClosureTurf ®, an artificial turf cap system. Though more expensive than a natural grass cover at the outset, ClosureTurf ® was calculated to provide a three-year payback in reduced maintenance (mowing and erosion repair). Because the artificial turf requires less soil, there was room for an additional 45,000 cubic yards of waste in the permitted airspace, prior to closure.
From bottom to top, the closure system consisted of an intermediate cover soil foundation, a 50-mil LLDPE structured geomembrane layer (which will offer savings on future piggyback expansion lining), an engineered artificial turf layer, a 0.5″ sand ballast layer, and cement-lined stormwater conveyance channels.
