Geogrid

Polyester warp knitted geogrid

Polyester warp knitted geogrid has a wide range of applications:

Road engineering: used to reinforce the road base to improve the load-bearing capacity and service life of the road.

Railway engineering: enhance the stability of railway subgrade and reduce uneven settlement of tracks.

Port engineering: In the construction of docks and yards, it can strengthen the foundation and improve the carrying capacity of the site.

For example, in a road reconstruction project in a certain city, polyester warp-knitted geogrids were used to reinforce the base layer, which significantly reduced the occurrence of road cracks and improved the overall quality of the road. In the expansion project of a coastal port, the laying of polyester warp-knitted geogrid effectively solved the problem of soft foundation and ensured the safety and stability of port facilities.

Ask questions

FREQUENTLY ASKED QUESTIONS



What types of geogrids are there?

Common ones include plastic geogrids (including unidirectional plastic geogrids and bidirectional plastic geogrids), steel-plastic geogrids, fiberglass geogrids, etc.



What is the service life of geogrids?

Under normal use and environmental conditions, it can generally be used for more than 20 years, but the actual life span will be affected by factors such as material quality, use environment, and construction quality.



What are the differences in the performance characteristics of different types of geogrids?

Plastic geogrids have the characteristics of light weight, high strength, and corrosion resistance; steel-plastic geogrids combine the high strength of steel and the corrosion resistance of plastics; fiberglass geogrids have high tensile strength and high temperature resistance.



What special environments can geogrids adapt to?

For example, it can be used in acidic and alkaline soil environments, high-cold areas, humid environments, etc., but products with corresponding materials and performance should be selected.



What is the impact of the aperture size of geogrids?

The aperture size will affect the interlocking effect and drainage performance with the soil. Moderate apertures can better play a reinforcing role.
