Standard Drainage Net Geocomposites 1A1
Extruded HDPE net drainage core with PP geotextile filter/separator for use in drainage geocomposites.
Application
Typical applications include:
- Highways for vertical edge-of-carriageway drains to intercept lateral flow of ground water, reducing excavation and backfill quantities, and improving installation time.
- Used in retaining walls and bridge abutments to reduce pore water pressure and avoid backfill saturation.
- Suitable for engineered landfills requiring long-term chemical resistance and high compressive strength.
- Tunnels for ground-water-seepage interception between rock face and tunnel lining.
- Buried structures such as basements, culverts, car parks, and reservoirs.
Description
Extruded high density polyethylene (HDPE) net drainage core with a nonwoven polypropylene (PP) geotextile filter/separator bonded to one or both sides.
Features and benefits:
- Manufactured using Terram T1000LE, a 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 loading.
- Robust to survive installation and service life.
- Stable under load to resist deformation that could ultimately restrict flow.
- Good chemical resistance.
- High-volume flow paths for liquids and gases.
- Lightweight and easy to handle, making for easy installation, particularly against vertical faces such as bridge abutment.
