 (HDPE, LDPE, EVA, ECB) Geomembranes |
Product Description
Products Description
This product is extruded PE membrane formed by adding anti-oxidant, absorbent of ultraviolet and dyestuff into HDPE or LDPE or EVA and will provide an effective barrier to of liquid water and water vapor.
HDPE performs well in mechanical properties, ageing-resistance, chemical-resistance, climate-resistance and resistance to puncture.
LDPE & EVA feathers great elongation, good flexibility at low temperature, softness and easy installation.
ECB, high-class waterproofing rolls, is formed by combining ethylene polymer with oil-resin.
Application Range
Geomembranes are mainly applied in dam, reservoir, subway, artificial, lake, waste treatment and some industrial waterproofing projects.
