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.

Reinforced Application

• Reinforced embankment for railway and highway.

• Reinforced roadway sub-base

• Reinforced earth retaining wall, embankment and slop

• Reinforced stream channel and jetty

• Abutment erosion protection

• Soft foundation soil reinforcement

• Reinforced bridge abutment

• Reinforced asphalt pavement

• Ecological engineering for river regulation and restoration

• Reinforced retaining structure for waste landfill.

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 .
