Geotex composite liners shortens the construction time for projects and can reduce costs as installations can be done onsite without professional installers. | GEOMEMBRANE PROPERTIES | UNITS | GCL050 | GCL075 | GCL100 | GCL150 | GCL200 | | --- | --- | --- | --- | --- | --- | --- | | THICKNESS | mm  | 0.50 | 0.75 | 1.00 | 1.50 | 2.00 | | WIDTH | m | 7 | 7 | 7 | 7 | 7 | | LENGTH | m | 420 | 280 | 210 | 140 | 105 | | YIELD STRENGTH | kN/m  | 7 | 11 | 15 | 22 | 29 | | BREAK STRENGTH | kN/m  | 13 | 20 | 27 | 40 | 53 | | YIELD ELONGATION | % | 12 | 12 | 12 | 12 | 12 | | BREAK ELONGATION | % | 700 | 700 | 700 | 700 | 700 | | TEAR RESISTANCE | N | 62 | 93 | 125 | 187 | 249 | | PUNCTURE RESISTANCE | N | 160 | 240 | 320 | 480 | 640 | | STRESS CRACK RESISTANCE | hrs | 500 | 500 | 500 | 500 | 500 | | U.V.
