Two-way stretch geogrid, made of high molecular polymer, is formed through extrusion into sheet, punching, and vertical and horizontal stretching. It has great tensile strength in both vertical and horizontal directions. As its structure can also provide an ideal chain system of more effective force bearing and spreading for the soil, it is applicable to the reinforcement of permanent load-carrying foundations of large areas.
1. Increase the bearing capacity of roadbeds/foundations, and extend the service life of roadbeds/foundations.
2. Prevent the subsidence or cracks of roadbeds/foundations, and keep the ground even and nice.
3. Facilitate the execution of works, save time and labor, shorten the construction period, and lower the maintenance costs.
4. Prevent culvert cracks.
5. Enhance soil slopes to guard against soil erosion.
6. Decrease the underlayer thickness and save the construction cost.
7. Support the stability of grass-planting geonets in the side slope, and help for environmental greening.
8. Function as the false roof of coal mine in place of metal gauze.
Application:
Two-way stretch plastic geogrid is applied for the enhancement of embankments and subgrades, side slope protection, wall reinforcement, as well as the reinforcement of permanent load-carrying foundation of airports, parking lots, and wharf freight yards.
