Woven Geogrids are used for soft and hard rock mining, environmental engineering, roads and pavements, and earthworks and foundations where extremely high tensile strength with low elongation is required.
High tensile woven geogrids are manufactured from high-modulus and high strength long polyester fibres which are warp-knitted, bundled together and coated with PVC, Bitumen, SBR or acrylic acid. Polyester geogrids are preferred for a range of soil reinforcement applications, including slopes and retaining walls.
High strength woven geogrids have tensile strengths ranging from 40kN to 1000kN/m at strains of less than 10%. Woven geogrids can also be manufactured in a range of aperture sizes to suit specific applications. They are a good substitute for traditional metal mesh, plastic mesh, steel-plastic mesh and other materials.
Features of Woven Geogrids:
- High tensile strength and low elongation
- Excellent creep resistance
- High junction node strength
- UV resistant
- Corrosion resistant, chemically and biologically inert
- Flexible and durable
- Safe and easy to install
- Resist installation damage
- Cost effective
Mine grids are coated with a flame retardant and/or anti-static treatment.
Woven Geogrid Applications:
- Soft and hard rock mining – long wall shield recovery screens, mine roof and rib control, reinforced highwalls, temporary and permanent tunnel support, heap leach and tailings
- Soil stabilisation
- Subgrade improvement
- Piled foundations
- Bridging voids and sinkholes in landfills
- Reinforced earth structures on poor foundations
- Road stabilisation, railways and pavement construction
Note: These geogrids are not recommended for use as a road base, or other applications that require fill greater than 40mm deep.
