Every containment project fails at its weakest layer. Hover or tap an industry to see the challenge we design for and the material system we recommend.
Need a layered liner design? Our engineers can review your cross-section drawings.
Primary liner
Mining & Heap Leach Pads
Heap leach pads, tailings ponds, ash yards and process tanks demand liners that withstand acidic or alkaline solutions and heavy ore loads without stress cracking.
Leachate barrier
Landfill & Waste Disposal Plants
Municipal and industrial landfills rely on composite liner systems that keep leachate out of groundwater, combined with drainage layers for leachate collection.
Lagoon lining
Environmental Protection Projects
Sewage ponds, wastewater lagoons, biogas digesters and power-plant regulating ponds need watertight, UV-stable lining that stays intact through water-level cycling.
Pond liner
Aquaculture & Agricultural Breeding
Fish, shrimp and lotus-root ponds, irrigation canals and farm reservoirs benefit from liners that cut water loss, simplify cleaning and protect stock quality.
Cellular confinement
Embankment & Riverbank Reinforcement
Shallow channels, riverbeds, banks and beaches are stabilized by confining infill in geocells, with geotextile filtration preventing soil migration.

Geosynthetics Questions Engineers Ask Us
Practical answers drawn from supplying liner, filtration and drainage materials to real projects. For project-specific values, always refer to your design specification.
Get the Technical CatalogWhat is the difference between HDPE and LDPE geomembrane?
HDPE geomembrane has higher density, stiffness, chemical resistance and UV durability, making it the standard choice for landfills, heap leach pads, tailings and wastewater lagoons.
LDPE and LLDPE are more flexible and elongate further before failure, so they conform better to uneven subgrades and settlement — common in tunnels, canals, aquaculture ponds and decorative water features.
How do I choose the right geomembrane thickness?
Thickness depends on the application, local regulation, subgrade condition, cover load and exposure. Lighter gauges around 0.5–1.0 mm are common for aquaculture and agricultural ponds, while many regulations specify 1.5 mm (60 mil) HDPE or thicker for municipal landfill and mining base liners. Confirm against your project specification and governing standard.
When should I use textured instead of smooth geomembrane?
Textured (coarse-surface) geomembrane increases interface friction with soil and geotextile, improving stability on side slopes such as landfill cell walls and heap leach pads. Smooth sheet is typically used on flat bases and where slope stability does not govern the design.
Why is a geotextile installed with a geomembrane?
A needle-punched non-woven geotextile acts as a protective cushion that reduces puncture risk from stones and aggregate, while also providing separation and filtration. Heavier geotextiles are chosen where cover material is coarse or overburden loads are high.
How is geomembrane seam and liner integrity tested?
Dual-track hot-wedge seams are usually checked by air-pressure testing of the channel between the two welds; extrusion welds are checked by vacuum-box or spark testing, and destructive peel and shear samples are taken at intervals. After installation, electrical leak location surveys can detect holes in the liner.
Can Changhong customize geosynthetic specifications?
Yes. Raw material, thickness, width, roll length, color, surface texture and packaging can be customized. Share your application, project area, target standard and destination port, and our team will recommend a suitable material and provide technical datasheets.
