I. Core Structure and Materials

Fiberglass Geogrid: Made of high-strength, alkali-free glass fiber, it is manufactured into a mesh substrate using advanced warp knitting technology, and then coated to form a semi-rigid product. It possesses high tensile strength in both longitudinal and transverse directions, low elongation, high elastic modulus, and excellent resistance to high and low temperatures.

Warp-knitted Polyester Geogrid: Made from high-strength polyester industrial filaments, it is warp-knitted into a directional mesh fabric, and then coated with PVC. The warp and weft yarns are bound together at their intersections by high-strength fiber filaments, resulting in a stable structure.

Plastic Geogrid: Made from high-molecular polymers such as polypropylene and polyethylene, it is stretched and molded, available in uniaxial and biaxial stretching types, and possesses excellent creep resistance and aging resistance.

III. Core Advantages (Compared to Traditional Reinforcement Solutions)

Extremely High Tensile Strength: High tensile strength in both warp and weft directions, large modulus, effectively dispersing load stress and significantly improving foundation bearing capacity.

Low Deformation and Creep: Extremely low elongation (≤10%), not easily deformed over long-term use, and good structural stability.

Strong Interlocking Effect: The grid structure allows soil, gravel, and other fillers to be embedded within, significantly increasing the coefficient of friction (up to 0.8~1.0) and providing strong pull-out resistance.

Convenient and Efficient Construction: Lightweight and flexible, easy to cut and connect on-site, allowing for overlapping and requiring no special construction machinery.

Excellent Weather Resistance and Durability: Resistant to high temperatures, low temperatures, aging, acids, alkalis, and corrosion, adaptable to various harsh environments.

Economical and Environmentally Friendly: Effectively reduces project costs, extends project lifespan, and reduces maintenance costs.

IV. Applicable Scenarios

Road Engineering: Asphalt pavement and cement concrete pavement reinforcement, old road repair, prevention of reflective cracking

Railway Engineering: Railway ballast protection, railway retaining wall reinforcement, bridge abutment foundation stabilization

Water Conservancy Engineering: Embankment slope protection, water conservancy project reinforcement

Foundation Treatment: Soft soil foundation reinforcement, roadbed reinforcement, reinforced soil retaining walls and slopes

Other Fields: Airport runways, desertification control, municipal roads, etc.

V. Construction Key Points

Substrate Preparation: Level and clean the existing road surface or foundation, removing debris and sharp objects.

Geogrid Installation: Lay the geogrid smoothly on the base layer, with an overlap width of ≥5cm laterally and ≥10cm longitudinally.

Fixing and Anchoring: Ordinary geogrids require fixing with steel nails; self-adhesive geogrids can be further constructed after compaction.

Covering and Compaction: Lay asphalt mixture or filler, and compact it moderately with a road roller.

VI. Selection Recommendations

By Material: Fiberglass geogrids are suitable for pavement reinforcement and preventing reflective cracking; polyester geogrids are suitable for soft soil reinforcement and retaining wall reinforcement; plastic geogrids are suitable for long-term projects requiring creep resistance.

By Strength: 20-40 KN/m specifications are generally suitable for roadbed reinforcement; for heavy-load roads, bridge abutments, and other projects, high-strength specifications of 50 KN/m or higher are recommended.

By Width: Select widths of 1-6m according to the construction area to reduce overlaps and improve construction efficiency.
