The most common product in the
family of Geosynthetics is non woven geotextile fabrics. This
product is a random assembly of synthetic fibers, put together,
which are mechanically & thermally bonded to make into a single
layer, commonly made of non woven polypropylene geotextiles and
polyester types. Geo textile fabrics are manufactured that based on
typical application required.
The weight range of this product in civil engineering applications
are typically ranging from 100gsm to 2000gsm. Its main function is
1) Filtration 2) Separation 3) Reinforcement and 4) Drainage.
Its applications includes:
- Road construction, highways and highway embankments.
- Airport runways.
- Shore protection in reclamation works.
- Asphalt repaving of roads.
- Coastal and riverbank revetment systems.
As a Separator used between unsuitable material and good bag
filled material, this usage will reduce the excavation depth of
unsuitable sub-grade. It reduces the aggregate thickness to
stabilize the sub-grade. The non-woven geotextile fabric maintains a
uniform settlement of the sub-grade and hence improve the sub grade
strength and prolong the life of the system.
As a Filtration polypropylene geotextiles have different range of
pore openings to reduce the potential of clogging. The range of pore
openings shall be compared to the grain size of the material to be
filtered to obtain the optimum filtration.
JP non-woven geotextiles not only acts as a filter and a separator
but also reduces the maintenance of erosion control systems and
costs.
Besides providing high puncture resistance, it also provides
lateral in-plane drainage for the system. It effectively filters
fine slit soils that are subjected to turbulent flow. Hence
maintaining and enhancing the stability of erosion protection
structures.
As reinforcement non-woven geotextiles' function involves
stabilization of a soil mass by provision of tensile strength fabric
system.
Drainage is related to the role of filtration and is a function of
the permeability of a geotextile and its pore opening size or
photometry. Water is conveyed along the plane of the non-woven
Geotextile due to its construction and then to an outlet. Water may
be vertically or horizontally conveyed.
"JP" Nonwoven Geotextiles can be used for at least 80
specific applications.
