Excellent Properties of HDPE geomembrana
HDPE geomembrane is a flexible waterproof liner with a very low permeability coefficient (≤1×10⁻¹⁷ cm/s), making it ideal for pond liners, dams, and landfill lining.
Suitable for extreme conditions, HDPE geomembrane performs reliably from -70℃ to 110℃, ensuring stability in hot deserts and cold climates.
Resistant to acids, alkalis, oils, and industrial effluents, HDPE geomembrane is widely used in mining leach pads, wastewater treatment, and chemical containment.
With excellent tensile properties, HDPE geomembrane sheets and rolls meet demanding engineering standards for durability and safety.
Outstanding anti-aging performance allows long-term exposed use without losing mechanical strength, suitable for reservoirs, canals, and slope protection.
High tensile strength and elongation enable HDPE geomembrane liners to withstand differential settlement, seismic zones, and harsh geological environments.
Made from ≥97% virgin HDPE resin with carbon black, free of additives or harmful stabilizers. HDPE is approved in many countries as a safe packaging material.
Upoznati HDPE geomembrana
HDPE geomembrane is a waterproof liner made from high-density polyethylene, designed to prevent seepage in ponds, landfills, dams, and other containment projects.
It is produced from virgin HDPE resin with carbon black, UV stabilizers, and antioxidants, ensuring strength, flexibility, and long-term durability against weathering and chemicals.
Typical HDPE geomembrane thickness ranges from 0.3 mm to 3.0 mm. Lighter grades suit ponds and canals, while thicker liners serve landfills and mining sites.
Yes. HDPE geomembrane has an extremely low permeability coefficient, making it fully waterproof for ponds, reservoirs, and leachate control in landfills and mining facilities.
HDPE geomembrane liners are widely applied across multiple industries:
Ekološki & Sanitation – landfill liners, wastewater treatment, hazardous waste storage, chemical warehouses, industrial waste, and construction or demolition debris containment.
Water Conservancy – seepage control and reinforcement for rivers, lakes, reservoirs, dams, canals, cutoff walls, and slope protection.
Municipal Engineering – metro tunnels, underground structures, rooftop water tanks, green roof gardens, and sewer pipe lining.
Landscaping – artificial lakes, decorative ponds, golf course water features, and slope protection.
Petrochemical – chemical plants, refineries, fuel tank bases, reaction tanks, sedimentation ponds, and secondary containment.
Mining – heap leach pads, tailings dams, settling ponds, slurry storage, and mining waste containment.
Poljoprivreda – irrigation canals, reservoirs, drinking water tanks, and farm water storage ponds.
Akvakultura – fish ponds, shrimp farms, and coastal aquaculture slope protection.
Salt Industry – salt crystallization ponds, brine ponds, and salt pool covers.
HDPE geomembrane can last 20–30 years or more, depending on thickness, UV exposure, and site conditions, making it a cost-effective long-term containment solution.
Vrste površina i opcije boja of HDPE Geomembrane
Double-Smooth HDPE Geomembrane
Manufactured from high-quality virgin polyethylene with ~2.5% carbon black, antioxidants, and UV stabilizers through a co-extrusion process. It offers excellent aging resistance and impermeability. In underground applications such as aquaculture ponds, swimming pools, or leachate tanks, its service life can reach 20–50 years. When used as exposed capping layers, lifespan is typically shorter, about 5–10 godina depending on UV exposure.
Double-Textured HDPE Geomembrane
This type features rough surfaces on both sides, increasing friction with soil or geotextiles, which is critical for slope stability in landfills and mining pads. Its chemical resistance and UV performance are similar to double-smooth liners, with a service life of 50–70 years under normal conditions. In harsh climates (high UV, extreme heat, or chemical exposure),lifespan may be reduced.
Rough-Surfaced HDPE Geomembrane (Single or Double)
Rough geomembranes are designed to provide higher interface friction, making them ideal for steep slopes, landfill sidewalls, or projects requiring soil cover and secondary geotextile installation. With proper installation and protection, their expected lifespan also exceeds 50 years, though sharp objects, continuous exposure, or poor maintenance can shorten durability.
Crna HDPE geomembrana
The most widely used type, made by adding carbon black during production. It offers excellent UV resistance and durability. Commonly applied in landfills, aquaculture ponds, wastewater treatment, and dam lining projects.
Bijela HDPE geomembrana
Produced from pure virgin HDPE resin without color masterbatch or recycled material. The white surface reflects sunlight, reduces heat absorption, and extends service life in exposed environments.
Black-Green HDPE Geomembrane
Designed with one side black and the other green. Frequently used for landfill capping systems, where the green surface improves aesthetics and mimics vegetation when viewed from above, while maintaining impermeability. treatment, and dam lining projects.
Blue HDPE Geomembrane
Manufactured from high-density polyethylene with blue coloration. It is especially suitable for swimming pools, aquariums, and decorative water facilities, providing impermeability with a visually appealing finish.

Ugradnja HDPE geomembrane,Zavarivanje & CQA
Metode zavarivanja
Dual Hot-Wedge Welding: Used for production seams in HDPE geomembrane installation. Creates two parallel welds with an air channel for easy non-destructive testing.
Zavarivanje ekstruzijom: Applied for detail work, patches, and pipe penetrations. Uses filler rod to secure overlaps where wedge welding is not possible.
Širina preklapanja: Typically 100–150 mm to ensure seam integrity in both smooth and textured geomembranes.
Postupci kontrole kvalitete (CQA)
Probni zavari: Conducted daily to confirm correct temperature, pressure, and speed before full-scale seaming.
Mapiranje šava: Each seam is logged and marked on project drawings for traceability.
Zapisi: Welding logs include operator, machine ID, weather conditions, and parameter settings.
Metode ispitivanja
Non-Destructive Tests (NDT):
Test vakuumske kutije: Detects leaks in flat seams.
Air-Channel Pressure Test: Performed on dual hot-wedge seams to verify integrity.
Destructive Tests (DT):
Peel and Shear Tests: Samples are taken at defined intervals (e.g., every 150–300 m²) and tested per ASTM D6392.
Compared with LLDPE, PVC, or EVA liners, HDPE geomembrane welding requires higher precision and stricter QA. The advantage is stronger, longer-lasting seams suitable for landfills, reservoirs, and industrial containment.

Osnove od Wholesale HDPE Geomembrane
Uključite vrstu projekta (jezerce, odlagalište, rudarstvo, rezervoar), potrebnu debljinu, površinu (glatka / teksturirana), željenu veličinu role i uvjete isporuke (FOB/CIF + luka).
Yes, free HDPE geomembrane sheet samples are available for evaluation prior to bulk purchase.
Tipično vrijeme isporuke je 15-25 dana za proizvodnju, plus raspored otpreme ovisno o odredišnoj luci.
Standardna širina role za izvoz je 5,8 m, koji je optimiziran za utovar kontejnera. Veće širine kao npr 7–8 m također su dostupni, ovisno o stvarnim uvjetima utovara kontejnera. Duljina role obično se kreće od 50–150 m, prilagođen debljini. Po potrebi se mogu isporučiti gotove ploče po narudžbi.
Težina (g/m²) = Debljina (mm) × Gustoća (g/cm³) × 1000.
For HDPE geomembrane with density 0.94–0.96 g/cm³ (prema ASTM D792), košuljica od 1,0 mm teži oko 940–960 g/m².
Kapacitet se izračunava na temelju 40HQ ≈ 25 tona težina utovara. Točan broj role ovisi o debljini i širini role; izračunavamo prema težini obloge po m² i ograničenju težine kontejnera.
Preporučena minimalna narudžba je 5000 m². Budući da je geomembrana glomazna i teška, predlažemo barem jednu 20GP kontejner za učinkovitu otpremu. Također možemo pomoći u konsolidiranje s drugim teretom ako je potrebno.
