Geotextile-membrane composite liner 


1.Introduction

Shandong Dageng Group are the manufacturer of geotextile,geomembrane and their composite. For geotextile,we have different raw material,such as polyester and polypropylene,short fiber needle-punched and continuous filament spunbonded geotextile. For membrane,we have HDPE,LDPE,PVC membrane,black and white,with different thickness available. Our nonwoven geotextile can be thermally bonded together with membrane for composite membrane.Composite membrane has the function of filtration,isolation,drainage,protection,and geotechnical reinforcement.Normally for composite membrane have two forms,one is membrane composited with one layer of geotextile,another is membrane composited with two layers of geotextile. As the protection layer of membrane,geotextile can protect membrane from physical and chemical harmness. The composited membrane should be extended from the bottom to the high position, and do not be pulled too tightly.Taking into account the actual situation of the project,the laying sequence of the slope should taken from the top to the bottom.
