Question:

What are the differences of seepage-proof geomembrane and polypropylene fiber impervious geotextile?

nan

Answer:

The seepage-proof geomembrane is made of high density polyethylene by flat extrusion or blow molding. The white seepage-proof geomembrane is heated and covered with polypropylene fiber geotextile top and bottom which finally becomes polypropylene fiber impervious geotextile. It has a good extensibility and environmental resistance as well as better anti-seepage effect. The seepage-proof geomembrane is usually black or white HDPE.
Watercourse. The excellent environmental stress cracking resistance of seepage-proof geomembrane enables it to be used in large seepage-proof projects such as landscape lake, impounding reservoir and other projects, the anti-seepage effects are basically same: Toilet waterproofness seepage-proof geomembrane is made of high density polyethylene (HDPE) Tunnels: Reservoir, polypropylene fiber impervious geotextile is made of polypropylene fiber (PP). Polypropylene fiber impervious geotextile has a high friction coefficient which are often used in small buildings. These impermeable materials are both acid- and alkali-resisting.
