Waterproof and Impermeable Geomembrane
In modern civil engineering and environmental protection, absolute seepage control is critical. Our high-performance geomembranes are engineered as impermeable barriers, providing reliable waterproofing and containment solutions for a wide range of heavy-duty projects.


Manufactured from high-grade polyethylene (HDPE or LDPE), these liners offer exceptional chemical resistance and mechanical strength. They effectively prevent the leakage of hazardous liquids, wastewater, and toxic gases into the surrounding soil and groundwater. The material is highly resistant to punctures and tears, ensuring structural integrity even under extreme earth pressure. Furthermore, our geomembranes are treated with carbon black and UV stabilizers, guaranteeing long-term durability and resistance to harsh weather and prolonged sun exposure.


Our geomembranes are highly versatile and widely applied in critical infrastructure. They are extensively used as landfill liners for waste management, impermeable layers for artificial lakes, reservoirs, and aquaculture ponds, as well as seepage control in mining tailings and agricultural irrigation. Available in various thicknesses and roll sizes, they can be easily welded on-site to create a continuous, leak-proof barrier. By choosing our geomembranes, engineers ensure long-lasting environmental protection and resource conservation.

FREQUENTLY ASKED QUESTIONS

What is the thickness of HDPE geomembrane?

Usually 0.3-3mm, customization is acceptable.

Can the geomembrane be covered with soil?

The geotextile usually needs to be backfilled with a soil layer for protection, such as lotus ponds and fish ponds, which require backfilling with a 20 cm soil layer.

What are the application areas of HDPE geomembrane?

HDPE geomembrane can fully meet the application requirements of industries such as sanitation, water conservancy, construction, municipal engineering, gardening, petrochemicals, mining, salt industry, agriculture, and aquaculture.

What is the general service life of geomembranes?material is PVC drainage pipe made of?

The service life of geomembranes is a range, and the specific years depend on many factors. The service life when exposed to the outside can reach more than 5 years; when used underground, it can reach more than 50 years.

What are the types of geomembranes?

There are many types of geomembranes, mainly including HDPE, LDPE, PVC, composite geomembranes, etc. Dingrun specializes in the production of geomembranes, welcome to consult.
