GeosFilter
is a polyester
needle-punched nonwoven
geotextile made of continuous
filament fiber for drainage,
filtration, separation
and reinforcement in public
works such as river or
tide bank protection,
blind ditch and tunnel
works
Through special
designing and production
process, Geos
Filter is produced
so that it can provide
optimum physical and hydraulic
properties suitable for
public works. Geos
Filter has higher
tensile and tearing strength
than other products, and
also has uniform openings
in filament fibers. The
uniform openings are consistant
through out the filter.
Uniform openings(AOS)
provide excellent hydraulic
performances.
GeosFilter
made of 100% polyester
has a good resistance
to UV light, aggressive
bacteria in soil, acid
and akali agents.
GeosFilter
is a geotextile filter
which doesn’t make environmental
contaminants and it is
stable at temperatures
of -40℃ ~ 100℃.
As Geos Filter
has flexable and strong
structure, it can be easily
seamed and installed.
Geos Filter
is produced in various
widths from 2.1m to 4.2m
and well adapted for field
works. It significantly
reduces construction costs.
The specific gravity of
Geos Filter
is 1.36 which allows an
excellent underwater installation.
