Tri-Dimension Compound Geonet Durable And Corrosion-Resistant For
Various Applications
Product Introduction
Thi-dimension compound geonet for drainage is made of a unique
thi-dimension geonet and adhesive with geotextiles on both sides.
It has the property of geotextile(filtration) and geonet(drainage
and protection), it provide a complete function system"
filtration-drainage-protection". The core of net with its unique
tri-dimension structure can bear higher compressing load in
construction and remanin the certain thickness, provide a good
water conductivity.
Product Application
Darinage for the landfill, roadbed and road surface, railway,
tunnel, underground structure, back of retaining wall, garden and
playground, etc.
Product Property
1. Excellent drainage
The three-dimensional composite drainage network has the drainage
performance equivalent to a meter thick of gravel drainage, capable
of quickly draining moisture from the soil.
2. High tensile strength
This material has high tensile strength, reducing the chances of
geotechnical fabric embedding into the mesh core, ensuring
long-term stable drainage performance.
3. High Load-bearing Capacity
Three-dimensional composite drainage network can withstand about
3000 kPa of compressive load, and can maintain good drainage
performance even under high load.
4. Durability
The material is corrosion-resistant, acid and alkali resistant, and
has a long service life.
5. Easy Construction
Due to its lightweight and easy-to-lay features, the
three-dimensional composite drainage net can shorten the
construction period and reduce engineering costs.
In summary, three-dimensional composite drainage networks are an
efficient and durable drainage material suitable for a variety of
engineering scenarios.
