Improve Drainage With Drainage Geonet 7mm Three-Dimensional
Composite Drainage Mesh
Product Introduction
7mm three-dimensional composite drainage net is a new type of
drainage geotechnical material, which is mainly made of
high-density polyethylene (HDPE) as raw material and processed by a
special extrusion molding process. The material has a three-layer
special structure. The middle ribs are rigid and arranged
longitudinally to form a drainage channel. The ribs arranged
crosswise up and down form a support to prevent the geotextile from
embedding in the drainage channel. Even under very high loads, it
can maintain high drainage performance.
Product Application
7mm three-dimensional composite drainage mesh is a new type of
drainage geotechnical material. It is mainly composed of
high-density three-dimensional composite drainage mesh and is
mainly used in drainage projects such as railways, highways,
tunnels, municipal projects, reservoirs, and slope protection. Its
effect is remarkable.It can not only replace traditional sand and
gravel layers, but also has advantages that traditional materials
cannot match in terms of drainage in landfills, roadbeds and tunnel
inner walls.
Product Property
Strong drainage: The drainage performance of the three-dimensional
composite drainage net is equivalent to one-meter thick gravel
drainage, which can quickly drain the accumulated water.
High tensile strength: Even under very high pressure, it can
maintain stable drainage performance.
Corrosion resistance: The material is acid and alkali resistant,
has a long service life, and is suitable for drainage needs in
various harsh environments.
Reduce the probability of geotextiles embedded in the mesh core:
The special structural design reduces the possibility of
geotextiles embedded in the drainage channel, ensuring long-term
drainage efficiency
