Considering the properties of LiteEarth material and its installation method, it is highly unlikely that it will uplift or flutter under wind exposure.

Due to its unique material properties and secured anchoring installation, the LiteEarth earth capping system has proven inherent resistance to waves and wind uplift.
Based on recent laboratory data and wind uplift calculations, LiteEarth can resist up to Level IV hurricane wind speeds. This is crucial for lasting stability and protection when capping potentially hazardous sites, such as Municipal Solid Waste (MSW) sites or Coal Combustion Residuals (CCR).
LiteEarth is an engineered composite for interim and long-term closure, consisting of 45 mil EPDM geomembrane, woven geotextile and synthetic grass. The system is installed using a patented seaming technology and earth anchors which provide a very stable defense against environmental factors. The spacing, size and depth of the earth anchors can be adjusted to meet wind uplift specifications, and to minimize wind-induced vibration or ripple of the material.
LiteEarth is a robust and thermally stable composite, with twice the mass of a standard 60 mil HDPE and half the linear thermal dimensional change of polyethylene. EPDM’s high frictional resistance against soil inhibits movement of LiteEarth across the ground. The unique combination of these factors makes LiteEarth inherently resistant to waves, wind uplift or flutter.
The properties of alternative capping materials such as HDPE or LLDPE have shown tendencies to wrinkles and waves, which could lead to cracking, puncture or shifting of the membrane. Any rupture in the closure surface can release gases, water and other hazardous materials between the landfill and the environment.
“Considering the properties of LiteEarth material and its installation method, it is highly unlikely that it will uplift or flutter under wind exposure,” said Chuck Fleishman, director of LiteEarth. “The system has been extensively tested for both material and performance qualities to prove its lasting durability and safety.”
The LiteEarth system is applicable for long-term closure of Municipal Solid Waste (MSW), Coal Combustion Residuals (CCR) and other Monofils and Mining, and meets or exceeds requirements for a Final Cover as specified in RCRA Subtitle D closure and post closure regulations.

LiteEarth is an advanced, engineered and fully-tested earth capping system which permanently combines synthetic turf and EPDM geomembrane into a long-lasting composite using an industrial grade adhesive. The result is an efficient, economical and environmentally-responsible closure solution with very low installation and life cycle costs. The system has been fully tested according to ASTM and regulatory standards. LiteEarth synthetic turf is manufactured by industry leader Act Global.
