Advantage:
• Using seat belt and geogrid+Mesh net produces Geocontanier
• The Geocontanier has junction strength , not easy cause rupture.
• Using seat belt as hook , it can support high load (2.5ton)
• Each Geocontainer has four belt hook , it is easy to apply to construction.

ComparisonItem Conventional Geogrid YEN SIGN GEOGRID
Junction The junction strength is
low and prone to break
during construction.
Our product is manufacturing
by knitting technique.
It can process higher tensile
strength than woven junction.
Aperture Difficult to satisfy the
design criterion of
aperture opening and also
decrease the strength .
Any kind of aperture opening
size can be made with keeping
tensile strength.
Coating material With poison PEV Non poison PE
Aperture shape Rectangular and square Hexagon can be made.
Color Black Any kind of color can be
produced for suitable
environment
Friction angle Low friction angle , will
cause displacement.
High friction angle .
