Geogrids
POLYPROPYLENE BIAXIAL GEOGRID
Our biaxial and uniaxial geogrids are made from high strength polypropylene and HDPE resin. These low creep geogrids are suitable for applications including retaining walls and bridge abutments, pavements, highways, airports, earth walls, earth dams, landfills, landslide repairs, railway track reinforcement and land fill sites. Geogrids are also available made from polyester fibres and we can supply geogrids with high quality geotextiles bonded to them.
Biaxial and uniaxial geogrids are UV stabilised with 2% Carbon Black. They are chemical and biologically resistant and resist installation damage.

HIGH MODULUS POLYESTER GEOGRIDS
Our polyester geogrids are characterized by high tensile strength and low creep. The geogrids are manufactured using high quality yards coated with a protective polymer. They offer an economical solution where non-cohesive, coarse grained soils must be reinforced because they adapt better to irregularities of the fill or subgrade than rigid geogrids. These grids have high junction strength, superior long term design strength and durability.
Applications include reinforcement of road sub-base, retaining walls and segmented block walls.

composite geogrids
Yuan Da’s composite geogrids are designed to stabilize soils where a both reinforcing and separation between a granular base and very fine soil is required. The geocomposite binds closely to the soil being reinforced, separates different soil types and provides an effective filter action.
These composite geogrids are made by bonding a nonwoven geotextile to a polypropylene geogrid. They have both a high tensile strength and modulus of elasticity, resist damage during installation, and weathering by the atmosphere.
