Soft Foundation Soil Reinforcement Geogrid Ground Grid Polyethylene Bidirectional Tensile
PRODUCT DESCRIPTION
Road Mine Soft Foundation Reinforcement Bidirectional Tensile Plastic Geogrid
Product Introduction
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, their main usage are as follows:
1. Enhance the bearing capacity of 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 tunnel from crack occurring
5. Further solidity slopes to proof water and soil from losses
6. Reduce the surface thickness of the ground.
