Geomembrane Cushion

A heavy weight nonwoven geotextile can be used as a geomembrane cushion in civil applications such as retention/detention ponds. Placing a nonwoven geotextile above or below the impermeable geomembrane helps protect it from punctures from the stone placed on top or objects embedded in the subgrade.

Permanent Erosion Control

Heavy weight nonwovens are also effective for permanent erosion control applications utilizing heavier rip-rap and/or requiring extreme drop heights. A nonwoven geotextile functions as a filter, allowing water to move through the system while preventing migration of underlying soils. Heavier weight geotextiles can withstand placement of larger rip-rap without ripping or tearing. However, a 6-inch-thick aggregate protection layer may still be needed before placement of the rip-rap.

Separation

Heavier weight nonwovens also have the strength required to effectively function as separators and light-weight stabilizers.
