Composite Drainage Net product

Drainage Net / Composite Geonet

Drainage Net, also called Composite Geonet, is a two or three-layer three-dimensional drainage geosynthetic product which are often made with polypropylene PP or regenerated HDPE (geonet) and covered with double-sided thermally heat-bonded nonwoven geotextile on both sides or one side. It has excellent performance than traditional draining gravel. So it becomes a good alternative for gravel in drainage application. Huisen composite drainage net is widely used for landfill, railway system drainage, road drainage, tunnel and retaining wall.

3D Composite Drainage Net

Composite Drainage Net is a new type of dewatering geotechnical material, which the raw material is HDPE and manufactured via particular extrusion forming technique. It has three levels, the inner fillet has strong rigidity, arrange longitudinal to form dewatering channel, the upper and bottom fillet form support to avoid geotextile inserting into dewatering channel, that means even if under high load it can also keep good dewatering property. It is the best dewatering material currently who has below function:" filter -- dewatering -- ventilate -- protect".

Composite Drainage Net Manufacturer FAQ

Composite drainage net is widely used in drainage projects for railroads, highways, tunnels, municipal projects, reservoirs, slope protection, etc. We, Huisen, are a professional composite drainage net manufacturer, and are often asked various questions about composite drainage net. Now, we have listed the frequently asked questions from our customers below for your reference when purchasing. If you have any questions, you can also contact us directly, and we will be happy to receive your inquiries.


It is an engineered drainage product that consists of a molded polymer core and a fully encapsulated laminated geotextile. It is an effective alternative to drainage pipes and stone systems that
Enables the collection and conveyance of groundwater. It is often used in modern drainage systems for golf courses, sports fields and residential yards.

With decade of years of development, Huisen has been an international composite drainage net manufacturer and solution provider. Huisen composite drainage net has been installed on many projects around the world for over a decade with a proven track record. Extruded HDPE net drainage cores are designed to withstand extremely high compressive loads with minimal settlement and elastic recovery rates approaching 100%. Drainage composites with monofilament cores compress significantly at relatively low pressures, which can lead to significant reductions in surface settlement and flow rates.

All of Huisen composite drainage net have been tested with compressive loads between 20 and 200kPa to determine the flow rate capacity in accordance with EN ISO 12958. Flow rates at higher compressive loads are available on request.

When designed, installed and maintained in accordance with the published literature most Huisen Geotextiles and Geocomposites are sufficiently durable to achieve a design life of at least 100 years in most typical soil conditions.

  • High drainage (equivalent to one meter thick gravel drainage).
    Tensile strength should be high.
  • Reduce the chance of geotextile mesh core embedment and maintain long-term stable drainage.
  • Withstand great pressure and load for a long time (can withstand compression load of about 3000Ka).
  • Resistant to corrosion, acid and alkali, and long service life.
  • Easy construction, shortening the construction period and reducing the cost.
  • Excellent drainage function, can withstand high pressure pavement for a long time
  • High tensile and shear strength
  • Can withstand compression load of over 2000KPa
  • Compression resistance is much greater than that of ordinary drainage geonets
