Smooth Geomembrane A high-performance HDPE or LLDPE liner with a flat, non-textured surface. Designed for applications where maximum tightness is required, it forms a continuous barrier against fluids and dangerous gases. Our liners are manufactured from 100% virgin resin using advanced co-extrusion technology, which guarantees longevity even in the harshest of environmental conditions.
Core Performance and Advantages
Our smooth geomembranes offer exceptional resistance to aggressive acids, alkalis and leachate. A uniform surface ensures better hydraulic flow and cleaning in industrial tanks. The high tensile strength and elongation of the material accommodates natural settlement at the subgrade as well as mechanical stress. Special-focused advances and developments in carbon black help to achieve a much better UV stability to withstand for outdoor applications.
Diverse Engineering Applications
Geosynthetics Environmental: Liner, Primary & Secondary liner for Municipal Landfills and Leachate Collection Ponds
Water Conservancy: Firm waterproofing for large reservoirs, irrigation canals and dam facings.
Mining and Energy: provide the sealed containment for heap leach pads, tailings dams and brine evaporation ponds
Use in Infrastructure: Moisture barriers for roadbed foundations, railway subgrades and bridge abutments.

When your project demands a high-performance barrier with a consistent, low-friction interface, Smooth HDPE Geomembrane is the go-to solution. Engineered for maximum impermeability, its completely flat surface on both sides ensures a uniform seal that stands the test of time.While textured liners focus on grip, Smooth Geomembranes are all about efficiency and flow.

1. Water Resource Management
In massive water putting away projects, soil spilling is the principal weakness as it brings about exceptionally generous water misfortune, which in-lined into asset exhaustion and subgrade shaky quality. CHANGFENG Smooth Geomembrane is used to form a high impermeable island at the pond bottom. Eliminating seepage ensures maximum water retention and dependable storage, which substantially reduces operational costs in agricultural and municipal water management.
2. Environmental Protection
Waste Disposal and Containment of Landfills Whenever landfill sites are created, they face the constant threat from toxic leachate – a harmful even hazardous waste product leaching into the soil and groundwater around them. We implement our smooth geomembranes as primary and secondary liners to provide a complete barrier with no gaps. The material is, however, highly resistant to the chemical degradation found in harsh leachate and can provide long-lasting protection against potential environmental non-compliance issues from costly ecological damage.
3. Hydraulic Infrastructure
Hydraulic Engineering and Irrigation CanalsOld unlined irrigation canals waste as much as 50% of their water volume in absorption by soil before reaching the destination. The use of our smooth geomembranes to line these conveyance systems will lessen the seepage losses along with reduce soil erosion in canal banks. This maximizes efficiency in delivering water, minimizes dredging and maintenance operations, as well as providing a more stable hydraulic infrastructure.
4. Heavy Industrial Security
Mining and Industrial Process PondsThe nature of mining (especially heap leach pads and tailings dams) is such that corrosive chemicals, extreme mechanical loads can penetrate the most common types of containment barriers. CHANGFENG heavy-duty smooth liners are designed to perform under severe chemical exposure and extreme high pressure. They serve as the first line of defence that stops dangerous runoff reaching the aquifer, allowing beneficial resource extraction to occur without threatening local habitats.
5. Sustainable Aquaculture
Commercial Aquaculture and Landscape Characteristics Commercial fish farms need barrier technologies that have 100% sealing performance to prevent pollication and are also considered non-toxics for aquatics. Traditional materials can leach chemicals that are toxic, or even just not last under UV conditions. We manufacture UV-stabilized geomembranes that are certified bio-safe and provide a healthy environment for both fish and plants. Providing exceptional puncture resistance and many years of durability ensures a low maintenance, leak-free ecosystem for years to come.

Q1 What are uses of smooth HDPE geomembranes?
A: It is used for leak containment in landfills, mining leach pads, water reservoirs and industrial wastewater hot-water ponds.
Q2: Do you provide tuning for geomembrane sizes?
A: Yes. We have much more item for supply, also much more OEM/ODM services offering for various thickness(0.5mm-3. 0mm) and roll widths of up to 8m in order to minimize on-site seams.
Q3. Is your material ASTM GM13 compliant?
A: Yes. Tested for international (ASTM GM13/GM17) standards required for global engineering projects, every batch is tested in-house.
Q4. Why we are using 100% virgin HDPE resin?
A: It has the highest UV resistance and chemical stability, 50 years+ service life of your project.
Q5: What is your B2B lead time?
A: Standard orders ship out of our Tai’an factory, and since we make these in-house, the turnaround time is quick (7-14 days) to meet urgent infrastructure requests.
Q6: What documents are issued for bidding in the project?
A: We offer TDS, MTR and engineering compliance installation guidelines
