Tianhai composite geomembrane is earthwork composition material that is produced from more than two materials of earthwork fabric (long and short fiber needle embroidering earthwork cloth, weaving earthwork cloth, plastic weaving cloth, etc.) and macromolecule material (HDPE film, LDPE film, EVA film, etc.) by rolling and thermal melting.

Since composite earthwork cloth has good plane drainage, excellent seepage resistance and high mechanic strengths such as tension, tearing, breaking and puncture resistance.
