A geomembrane is an impermeable synthetic liner or barrier used to control fluid migration in various engineering and environmental applications. Typically made from durable polymers such as HDPE, LLDPE, PVC, or EPDM, geomembranes are designed for long-term performance under demanding conditions.
Smooth geomembranes manufactured from quality high densitypolyethylene resins(HDPE) that comply with the most rigorousrequirements established for their use. The 0.5mm hdpegeomembrane is popular thickness,its widely used in aquacultureproject,fish pond,shrimp pond and irrigation pond.smoothGeomembrane, is a geosynthetic material with a flat and smoothappearance.

Applications
Aquaculture Application： Geomembranes are widely used in fish/shrimp ponds, hatcheries, and aquaculture tanks to create a controlled, leak-proof environment. Key benefits include: Water Retention & Sealing Prevents water seepage into the soil, maintaining optimal water levels. Reduces water loss, saving costs on refilling and treatment. Contamination Prevention Blocks pollutants, heavy metals, and harmful bacteria from entering the pond. Separates cultured species from groundwater contaminants. Improved Water Quality & Hygiene Smooth surface prevents sludge buildup, simplifying cleaning. Non-toxic materials ensure safe contact with aquatic life.
Mining Applications: In mining, geomembranes serve asliners for heap leach pads, tailings storage, and acid drainage containment, ensuring environmental protection and operational efficiency. Heap Leach Pads Used in gold, copper, and uranium extraction. Prevents leaching solutions from contaminating groundwater. Tailings Storage Facilities (TSF) Lines ponds holding mining waste (tailings), preventing toxic seepage. Reduces risk of dam failures and environmental disasters. Acid Mine Drainage (AMD) Control Blocks sulfide minerals from reacting with water, reducing acidic runoff. Often paired with geotextiles for added protection.
Landscaping Applications: Geomembranes play a crucial role in modern landscaping projects, offering waterproofing, erosion control, and aesthetic enhancement. Artificial Lakes & Decorative Ponds Ornamental ponds in parks, resorts, and residential gardens. Reflecting pools in urban plazas or architectural designs. Koi ponds and water features requiring clean, algae-free water. Rooftop Gardens & Green Roofs Urban rooftop gardens (commercial/residential). Green roofs with vegetation for stormwater management. Balcony gardens and planter boxes. Erosion Control & Retaining Walls Hillside stabilization in parks and highways. Retaining wall backfill protection. Golf course water hazards and sand traps.
