Warp Knitting Fiberglass Geogrid
Warp knitting fiberglass geogrid is a mesh reinforcement material, it's made from fiberglass by warp-knitting directional weaving process. It has extremely low elongation and high elastic modulus.
Fiberglass warp-knitted geogrid is a geosynthetic material made primarily of alkali-free glass fiber, using a warp-knitting directional weaving process to create a mesh-like substrate, which is then surface-coated (with modified bitumen or PVC). It possesses extremely high tensile strength, low elongation, and high modulus of elasticity (up to 67 GPa).
The core value of fiberglass warp-knitted geogrid lies in its extremely high rigidity—acting as a "rigid interlayer" in asphalt pavement overlays, it effectively suppresses stress and releases strain, making it an irreplaceable material for addressing reflective cracking in asphalt pavements. It is widely used in engineering fields such as asphalt pavement reinforcement, cement pavement reconstruction, airport runway reinforcement, and soft soil foundation treatment.
Our products can be manufactured according to GB/T, ASTM, ISO, and other standards, and all raw materials are pure new fiberglass.
Production Process: knitting directional weaving + coating treatment. The warp knitting process allows it to function even with minute deformations. The geogrid is coated with modified bitumen or PVC to improve its UV resistance and acid and alkali resistance.
Quality Control: The entire production process is monitored by automation. Strict factory inspections are conducted, to ensure that key quality control points fully comply with the standards.
After-sales Service: We have over one million square meters of construction experience, and our team can provide on-site construction services. We also offer remote technical guidance to assist with welding and construction.
Advantages
- Extremely low elongation: elongation at break ≤ 5%.
- High elastic modulus: up to 67 GPa.
- No long-term creep: Glass fiber is an inorganic material and will not undergo creep deformation.
- Good compatibility with asphalt
- Easy to install: Lightweight, easy to cut and connect on site.

- Prevention of Reflective Cracks in Asphalt Pavements
- This is the core application of fiberglass warp-knitted geogrids, which have become an irreplaceable material in treating reflective cracks in asphalt pavements.
- Reconstruction of Cement Concrete Pavements into Composite Pavements
- When overlaying asphalt on old cement pavements, laying fiberglass geogrids effectively inhibits reflective cracks caused by slab shrinkage.
- Road Widening and Reconstruction Projects
- Prevents cracks caused by the interface between old and new pavements and uneven settlement.
- Soft Soil Subgrade Reinforcement Treatment
- Facilitates water drainage and consolidation of soft soil, effectively inhibits settlement, evens stress distribution, and enhances the overall strength of the subgrade.
- Semi-rigid Base Course for New Roads
- Prevents pavement cracks caused by reflection of shrinkage cracks in semi-rigid base courses.
- Airport Runway Reinforcement
- Used for airport runway pavement reinforcement, improving load-bearing capacity and extending service life.
- Railway Subgrade and Embankment Slope Protection
- Used for railway subgrade reinforcement and embankment slope protection.
