2. What is Geotextile
1. Geotextile material: synthetic fiber.
2. Geotextile is a permeable geosynthetic material made of
synthetic fiber needles through punching or weaving. Geotextile is
one of the new materials and geosynthetics, and the finished
product is cloth-like. Geotextiles are divided into woven
geotextiles and non-woven filament geotextiles. Due to the plastic
fiber used, it can maintain sufficient strength and stretch even in
a dry state;
3. The reason why geotextiles can prevent corrosion for a long time
in soil or water with different pH levels is that there are gaps
between the fibers, so they have good water permeability. Because
the material of geotextiles is light, soft, and It is easy to
transport, which greatly improves the construction efficiency and
is very convenient to use.

4. The specific functions are as follows:
Geotextiles are widely used in geotechnical engineering such as
water conservancy, electric power, mines, roads and railways:
l. Filter material for soil layer separation;
2. Drainage materials for reservoirs and mines beneficiation, and
drainage materials for foundations of high-rise buildings;
3. Anti-scouring materials for river dams and slope protection.
5. Application
(1) Used as reinforcement in backfilling of retaining walls, or
used for anchoring panels of retaining walls. Build a wrapped
retaining wall or abutment.
(2) Reinforce flexible pavement, repair cracks on the road, and
prevent reflection cracks on the pavement.
(3) Increase the stability of gravel slopes and reinforced soil to
prevent soil erosion and frost damage at low temperatures.
(4) The isolation layer between the road ballast and the roadbed,
or the isolation layer between the roadbed and the soft foundation.
(5) The isolation layer between artificial fill, rockfill or
material yard and foundation, and isolation between different
frozen soil layers. Anti-filtration and reinforcement function.
(6) The filter layer of the initial upstream dam surface of the ash
storage dam or tailings dam, and the filter layer of the drainage
system in the backfill of the retaining wall.
(7) The filter layer around the drainage concealed pipe or the
gravel drainage ditch.
(8) The filter layer of water wells, relief wells or inclined
pressure pipes in water conservancy projects.
(9) Geotextile isolation layer between roads, airports, railway
roads, artificial rockfills, etc. and the foundation.
(10) Vertical or horizontal drainage inside the earth dam, buried
in the soil to dissipate the pore water pressure.
(11) Drainage behind the anti-seepage geomembrane in the earth dam
or embankment or under the concrete protective surface.
(12) Eliminate the water seepage around the tunnel, reduce the
external water pressure on the lining and the water seepage around
the buildings.
(13) Drainage of artificially filled soil foundation sports ground
foundation.
(14) Highways (including temporary roads), railways, embankments,
earth-rock dams, airports, sports fields and other projects are
used to strengthen weak foundations.
6. Quality Control
We have established a national-standard laboratory for in-house quality control and built a strict quality control system in all aspects from raw materials testing and production processes to final product quality testing.
Not only is stringent internal quality control carried out at OBOR, but regular testing and analyzing of our product performance is implemented by authoritative testing organizations in Europe and the United States.
