Geomembrane elongation: 380% -700%
LDPE geomembrane elongation is greater than 400%, which depends on different composite materials. composite geo-membrane elongation of general composite nonwoven material is between 40% ~ 100%; HDPE geomembrane elongation is greater than 700%; composite geomembrane depends PVC geomembrane elongation is greater than 200%
American standard is above 700% while LDPE geomembrane is over 400%; national standard 1 is more than 450%; urban construction department standard is also above 700%; national standard 2 is more than 550%
