LDPE Geomembrane
We are a manufacturer specializing in impermeable materials for diverse applications. Our LDPE Geomembrane represents a new generation of geotechnical seepage control solutions. Compared to HDPE geomembranes, which are based on plastic film, our LDPE product offers superior tensile strength and flexibility.
It is particularly well-suited for challenging scenarios such as:Artificial lakes, landscape water features, and aquaculture ponds,Anchor trenches and steep slopes in landfills and tailings ponds,Secondary liner systems within composite lining structures,we offer comprehensive technical support—from design consultation to installation guidance—tailored to your specific project requirements and geological conditions, ensuring a fail-safe impermeable engineering solution.
Product description
As a new generation of geotechnical seepage control materials, LDPE geomembrane is mainly polyethylene, ethylene, vinyl polymer and other materials polymerization, which absorbed the previous geomembrane on the basis of flexibility, but also increased its good extensibility, adaptability to deformation and other capabilities. Greatly increase its waterproof seepage control ability. The main purpose of the geomembrane is to provide waterproof and seepage control.
