Property of Biaxial Plastic Geogrid for Coal Mine road Railway highway:
L. Not easy to produce static after friction. In the coal mine, surface static resistance average is
Below lx109(LC
2. Good flame retardant performance, melt not burning under flam environment, even burning it
Will extinguish in lOs
3. Strong anti-corrosion property
4. High bearing capacity, low elongation

Application:
PP biaxial geogrids can be used to enhancement of permanent bearable soft including highway and railways embankment, slopes, tunnel, airport, parking lots, loaded pier and ground and their main usage are as follows:
1. enhance the bearing capacity fo road foundation and extend the duration of highway.
2. prevent highway surface from collapse, crack and being dirty.
3. be convenient for construction timesaving and cut down the cost of maintenance.
4. prevent tunel from crack occuring
5. further solidity slopes to proof water and soil from losses
6. reduce the surface thickness of the ground.
7. consolidate the net for growing grass on the slopes
so as to stabilizatio surrounding virescence.
8. be used for artificial top net of mines instead of metal ones.
It is of flame retardant and antistatics.
FAQ
What is geosynthetics ?
Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary.
What kinds of geosynthetics we have ?
Non-woven geotextile, geogrids, geocells, GCL, Geomembranes, Geonets, Geocomposites etc .
What is the geosynthetics used for ?
Hydraulic
Lagooning and Water Treatment, Ornamental Ponds, Golf Courses
Aquaculture and Desalination,Water Lagoons,Tanks, Reservoirs, Liquid Waste,Floating Cover Solutions, Drainage and Filtration
