1. Convenient construction, easy maintenance and economy.
2.Strong resistance to load and durability.
3.The water can be partially stored and the remaining water can be drained quickly.
4.It provides sufficient moisture and oxygen for plant production.
5.Light weight, the roof heat insulation function strong.
1. Greening project: the garage roof greening, roof garden, vertical greening, roof greening, football pitches, golf course, etc.
2. Municipal engineering: airport, road embankment, subway, tunnel, landfill, etc.
3. Construction: the upper or lower building foundation, inside and outside the basement wall, floor and roof, roof seepage control and heat insulation layer, etc.
4. Water conservancy project: the reservoir seepage water, reservoir, lake water seepage control, etc.
5. Traffic engineering: highway, railway basement, roadbed, dam and slope protection layer, etc.
