Basalt geogrid is a geomembrane material made primarily from alkali-resistant, acid-resistant, corrosion-resistant, and high-temperature-resistant basalt fibers, formed through a warp-knitted process to create a stable grid structure. It is then coated with a special layer to further encapsulate the basalt fibers, enhancing its stable structure and chemical corrosion resistance. Basalt fibers boast high tensile strength, resistance to high temperatures (260-650℃), compatibility with asphalt concrete in terms of thermal expansion coefficient, UV resistance, good chemical stability, and resistance to aging. As such, they are used as reinforcing substrates for asphalt or concrete pavements, effectively preventing the occurrence of road distress such as cracks and rutting, and addressing the issues of asphalt pavement's tendency to crack and deform.

Performance and Features

High tensile strength with low elongation, less than 3% elongation at break, reduces pavement settlement and deformation.

Excellent physical and chemical stability;

No long-term creep, maintaining long-term performance stability.

Excellent thermal stability, suitable and meets the high-temperature asphalt requirements during paving operations.

Low-temperature crack resistance, reducing or avoiding road cracking.

Compatibility with asphalt mixtures to prevent segregation.

Product Applications

For road reinforcement, old road repair, and strengthening of subgrade and soft soil foundations.

Enhancement for railway embankments, dam slopes, and airport runways.

For reinforcing and enhancing tunnel roofs

For coal mine tunnel reinforcement and false ceiling support.
