Terra-DRAIN™ EN-18 (Entangled Mesh) is a 0.75” (18 mm) thick prefabricated multi-functional drainage mat designed to either assist with root entanglement & soil reinforcement or act
as a moderate to high-flow drainage product in green roof or landscaping assemblies.
The geometric “zig-zag” patterned polypropylene core is produced from an extruded matrix of tangled monofilaments, which are heat-welded at the junctions to form a resilient structure. A non-woven polyester filter fabric is adhered to the surface of one side of the material to hold the soil or concrete away from the wall or deck and the core.
When used with the filament-side up, the product assists with root entanglement and soil reinforcement, allowing roots to grow into and become tangled with the 3-dimensional polymeric
core. This feature facilitates the easy transportation of vegetation from one place to another. Alternatively, when installed with the fabric side up, the mat creates a 0.75” thick air-space, enabling
incidental moisture to drain away and ventilate out effectively.
