1) UV resistant
2) High temperature resistance to up to 230℃ maintaining structure stability and original physical properties
3) High flat drainage and vertical permeability
4) High creep resistance
5) Resistance of erosion of chemicals in soil as well as the corrosion of gasoline and diesel etc
6) High elongation under certain stress, thus able to adapt to uneven and irregular bases
