HDPE LDPE LLDPE PVC EVA Geomembrane Liner Composite Geotextile Fabric for Civil Engineering
Geomembranes Composite Geotextiles Introduction:
Composite geomembrane based on non woven geotextile and PE membrane. There are:
One layer geotextile and one layer geomembrane;
Two layers geotextile and one layer geomembrane,
Two layers geomembrane and one layer geotextile and
Multi-layer geotextile and geomembrane.
Geomembranes Composite Geotextiles Properties:
1,It integrate permeation,inverse filter and drainage function, and has various functions such as isolation and reinforcement.
2,It has high synthetic strength, large removal strength and high puncture resistance.
3,It has strong drainage capacity, large factor and small expansion factor.
4,It has good aging resistance, wide environmental temperature range and stable quality.
Geomembranes Composite Geotextiles Application:
Widely used in dam, traffic tunnel, road, airport, drainage, housing, environmental protection and many other fields, main function is preventing leakage, protection, reinforcement etc.
