Introduction
LY Biaxial Geogrid is manufactured from Polypropylene. It is produced through the process of extruding, punching, heating, longitudinal stretching and transverse stretching.
Performance
High tensile strength at both longitudinal and transverse direction
Applications
Soft foundation reinforcing for highway, railway
Slope protecting projects
Landfill sites
Benefits
Improving bearing capacity of foundation
Preventing cracking and subsiding
Convenient to construct, reducing cost and maintaining expense
Product introduction
BIAXIAL GEOGRID COMPOSITER is a composite made of bi-axial polypropylene (PP) geogrid, heat bonded to a long fiber non-woven polyester geotextile that acts as a filter and soil separator. This geogrid is manufactured using a punching and drawing process whereby the polypropylene sheet is stretched in two directions, machine (longitudinal) and cross-machine (transverse). The result is a monolithic and isotropic geogrid with thick and wide ribs, thick integral nodes, and uniform square apertures. Engineered to be mechanically and chemically stable in aggressive soil environments, THIS-GEOCOMPOSITE allows sub-base drainage to help maintain structural stability, and is very effective in keeping expensive imported material from being contaminated by migration of fines from the saturated base soils.

Benefits:
- Reduces amount of aggregate needed= construction cost savings.
- Reduces soil excavation and backfilling= construction cost savings.
- Minimizes differential settlement and prevents upward movement of the subgrade = higher structural performance.
- Improves overall structural life= maintenance cost savings.
Applications:
- Site subgrades
- Railway ballasts
- Oil platform access roads
- Temporary military roads
- Mine haul roads
- Forestry and logging roads
- Coastal roads
- Parking lots
- Under hydro-electric transmission line towers
- Foundation support
