Blackwater Trading Estate United Kingdom Issue: 08 Date: 18.08.15 Page: 1 of 2 Extruded high density polyethylene (HDPE) net drainage core with a nonwoven polypropylene (PP) geotextile filter/ separator bonded to one side and an extruded (PE/EVA) geomembrane bonded to the other. Typical Applications include: — Highways: vertical edge-of-carriageway drains intercept the lateral flow of ground water. Modern fin drains reduce excavation, reduce backfill quantities and reduce installation time. In-slope drainage increases geotechnical stability. — Retaining walls and bridge abutments: to reduce pore water pressure and avoid backfill saturation. — Engineered landfills: with the additional requirement of long-term chemical resistance and high compressive strength. — Tunnels: ground-water-seepage interception between rock face and the tunnel lining. — Buried structures: vertical and horizontal drains for basements, culverts, car parks, reservoirs, etc. Terram Net drainage geocomposites are manufactured using Terram T1000LE, a unique geotextile filter developed specifically for use in drainage geocomposites for its high tensile modulus and ability to prevent soil ingress into the void space of the drainage core. Terram drainage cores are manufactured from HDPE nets which have been engineered to have good flow under high Mean Value (Applied tolerance Valu( Test Method Tensile Strength Tensile Elongation Geotextile Filter Pore Size - Mean AOS In plane water flow MD (hard platens)
