Bidirectional High Strength: Balanced longitudinal and transverse tensile strength, good load distribution
Corrosion resistance and anti-aging resistance: acid, alkali and salt resistance, microorganism resistance, UV resistance
Low creep: small deformation under long-term stress, strong stability
Grid interlocking: interlocked with soil/sand and gravel to limit lateral displacement
Easy to lay: Roll packaging, convenient and efficient transportation and construction
Good permeability: The mesh structure is conducive to drainage and reduces damage caused by accumulated water
Economic durability: Long service life, reduces backfilling and later maintenance
Biaxial geogrid is a high molecular weight geosynthetic material made from polypropylene (PP)/high-density polyethylene (HDPE) as raw materials, which is extruded, punched, heated and stretched in both longitudinal and transverse directions. It has a regular grid shape and can provide high-strength tensile and soil reinforcement effects in two orthogonal directions. It is commonly used in roadbed, slope, foundation reinforcement and other engineering projects.
Performance
- High Tensile Strength: Balanced tensile strength in both longitudinal and transverse directions, effectively bearing loads and improving soil stability.
- Excellent Creep Resistance: Small deformation under long-term stress, maintaining structural stability and reducing later settlement.
- Strong Corrosion Resistance: Resistant to acid, alkali and aging, suitable for complex soil and environment with long service life.
- Great Interlocking Force: Grid structure closely interlocks with soil and sand, limiting displacement and enhancing reinforcement effect.
- Easy Construction: Lightweight, easy to cut and lay without complex equipment, greatly improving construction efficiency.
Application
- Road Subgrade Reinforcement: Used in highway and railway subgrades to prevent settlement and cracking and extend service life.
- Slope Protection Engineering: Reinforces mountain and embankment slopes to avoid landslide and collapse and improve stability.
- Soft Soil Foundation Treatment: Improves bearing capacity of soft soil, quickly strengthens foundation and reduces uneven settlement.
- Dam Reinforcement: Applied to reservoirs and river dams to enhance structural strength and resist water erosion.
- Parking Lot Reinforcement: Strengthens parking lots and yards to prevent ground settlement and deformation and improve load capacity.
