Drainage Geonet The High-Performance Geosynthetic Material For
Reinforcement
Product Introduction
Geotechnical composite drainage net is a new type of geosynthetic
material that combines the advantages of geotechnical fabric and
geotechnical mesh core, providing comprehensive performance of
"filtration - drainage - protection". The emergence of this
material aims to solve many problems in traditional drainage
methods, such as low drainage efficiency and easy clogging.
Product Application
♦ Infrastructure construction
♦ Landfill Drainage
♦ Road surface and subgrade drainage
♦ Tunnel and Retaining Wall Drainage
♦ Reinforcement of the reservoir floor
Product Property
1. Excellent drainage: Its drainage performance is equivalent to a one-meter thick layer
of gravel drainage, capable of quickly eliminating accumulated
water.
2. High Tensile Strength: Maintains stable drainage performance even under high loads.
3. Durability: The good corrosion resistance and acid-base resistance make the
drainage net have a long service life.
4. Easy Construction: With a width of up to 4.4 meters, it allows for quick and
efficient installation, helping to shorten the construction period
and reduce costs.
As a high-performance geosynthetic material, the geotechnical
composite drainage net has been widely used in infrastructure
construction, waste landfill site drainage, road and subgrade
drainage, tunnel and retaining wall drainage, and reinforcement of
the bottom of reservoirs. Its multifunctionality and durability
make it an indispensable material in these fields.
