WHAT ARE GEOGRIDS?
They are composed of a single or multiple layers, usually made by extrusion and stretching of high-density polyethylene or polypropylene, or by weaving and coating high-tenacity polyester threads. The resulting grid structure has large openings that enhance interaction with soil or aggregate.
The high tensile strength and stiffness of geogrids make them especially effective as soil and aggregate reinforcement.
EXTRUDED UNIAXIAL GEOGRIDS
Manufactured from High-Density Polyethylene (HDPE), these are those that are pre-stressed in one direction and are typically used vertically in geotechnical engineering projects such as reinforced soil and retaining walls.
Physical Characteristics
Longitudinal rectangular openings
EXTRUDED BIAXIAL GEOGRIDS
Manufactured from Polypropylene (PP), these are those that are pre-stressed in two directions and are typically used horizontally in applications where the direction of primary stress is uncertain.
Physical Characteristics
Square openings
ADVANTAGES OF GEOGRIDS
- Increase the project's lifespan.
- Enhance the soil's mechanical and hydraulic properties.
