Drainage Geonets

Advanced Drainage System

Drainage geonet is a new type of dewatering geotechnical material, which is designed to complement or replace sand, stone and gravel. It’s a primary solution for waste disposal and civil engineering where hydraulic flow capacity is requested.

PRODUCT SUBCATEGORIES

G-Net® CM Series

G-Net® Bi-planar Series G-Net® Tri-planar Series

Composite Drainage Geonets

Used as a drainage layer to provide drainage, filtration, separation and protection.

G-Net® CM series are composite drainage geonets consist of bi-planar or tri-planar geonets heat-bonded with nonwoven needle punched geotextile on one side or both sides. The integrated core and fabric system optimizes drainage channel consistency, minimizes soil particle intrusion for maximum flow capacity, allows water to freely enter the drainage channel. It has the property of geotextile (filtration function) and geonet (drainage) and remain the certain thickness.

Applications

Landfills
Roads
Retaining wall

Features

High tensile strength
Long time stable water conductivity

Bi-planar Drainage Geonets

Designed for in-plane flows over large surface areas.

G-Net® Bi-planar series are bi-planar drainage geonets made with two sets of diagonally crossed parallel HDPE ribs intersecting at different angles and spacing. This unique strand structure provides superior compressive creep resistance and ensures continuous drainage performance over a wide range of conditions and long durations.

Applications

Landfill leachate collection
Foundation wall drainage
Methane gas collection
Pavement and roadway drainage

Features

Excellent drainage performance
Resistant to chemical and biological agents

Tri-planar Drainage Geonets

Higher transmissivity and higher compressive than bi-planar products.

G-Net® Tri-planar series are tri-planar geonets are made with two sets of parallel HDPE ribs separated by a central rib layer. This structure allows for channelized flow and higher drainage performance. The central ribs are designed to offer higher compressive strengths in challenging applications.

Applications

Landfills
Roads
Tunnels
Steep Slope

Features

High transmissivity
High compressive strength

Used in

01 Earthwork Construction

Steep slope, retaining wall, embankment

02 Road Works

Road, railway, highway, pavement, airport runway, tunnel, bridge

03 Environmental Engineering

Landfill, tailing, waste water treatment

G-Net® drainage geonets are a perfect synthetic drainage materials made from the excellent high-density polyethylene (HDPE) resin, which are designed to transmit fluids and gasses uniformly under various field conditions. The heavier and thicker strands provide high compressive strength and excellent transmissivity.

G-Net® drainage geonets are high resistance to UV, chemically stable and appropriate for using in rigorous environmental conditions. In double-lined containment applications, G-Net® drainage geonets are commonly used to create an interstitial space between two geomembrane liners as part of a leak detection system.

GeoTrans Technology provides the bi-planar geonets, tri-planar geonets and the composite drainage geonets.
