Geogrid

Polyester Biaxial Geogrid

Polyester Biaxial Geogrids are high-strength woven geosynthetics for bidirectional soil reinforcement in civil engineering. Made from high-tenacity PET yarns with PVC coating, they offer high tensile performance, low creep, and excellent chemical/weathering resistance. With tensile strengths from 20 to 1000 kN/m and customizable mesh sizes, they ensure reliable load distribution for transportation, industrial, and soil improvement projects. Their durable construction provides a service life over 100 years.

PRODUCT DETAILS

High-Strength Material Structure

Premium PET Yarn & PVC Coating Technology

Manufactured from high-modulus polyester yarns with a uniform PVC soakage treatment, these geogrids achieve superior mechanical strength and durability. The woven construction provides consistent mesh geometry and balanced load distribution across both axes. The coating shields the core from installation abrasion, hydrolysis, and alkaline environments, significantly prolonging service life while preserving long-term performance in demanding field conditions.

Superior Reinforcement Performance

Enhancing Bearing Capacity and Structural Stability

The geogrids effectively confine aggregate particles and spread applied loads over a wider area, reducing differential settlement and raising subgrade bearing capacity. With elongation at maximum load held at approximately 10%, they deliver an immediate tensioning response under traffic or static loads. This translates into thinner granular layers, lower material costs, and extended pavement life for highways, airports, and industrial yards.

Effective Soil Interaction and Long-Term Durability

Optimized Aperture Design for Reliable Interlocking

The precisely sized mesh openings (12.7–50 mm) promote strong mechanical interlock with surrounding soils and fills, enabling efficient load transfer at the interface. The PVC coating provides robust protection against UV radiation, moisture, and chemical attack, while independent tests confirm high resistance to installation damage across gravel, sand, and weathered rock. This ensures the geogrid retains its integrity throughout construction and the full service period.

Engineering Cost Efficiency

Reduced Fill Volumes and Accelerated Construction

By delivering high tensile efficiency with low creep, these geogrids allow engineers to reduce granular fill requirements by 30–50% compared to unreinforced sections. The lightweight rolls are easy to handle and install, cutting labor time and equipment usage. The combination of material savings, faster schedules, and lower maintenance needs delivers measurable cost reductions while meeting or exceeding structural performance criteria for critical infrastructure projects.
