This HDPE geomembrane —also called a \u003cstrong\u003eliner\u003c\/strong\u003e or impermeable sheet— is manufactured by Moltexo with professional-grade virgin resins, in a range of gauges from 400 to 8000, and designed for serious, long-lasting work: never as a temporary solution.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal impermeability:\u003c\/strong\u003e Dense molecular structure that blocks the passage of water and contaminating fluids, ensuring watertightness in ponds, canals, and foundations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVerified UV resistance:\u003c\/strong\u003e Carbon black content of 2.0 to 3.0% (ASTM D1603) to withstand years under direct Caribbean sun without degradation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMechanical durability:\u003c\/strong\u003e Excellent tensile, tear, and puncture performance according to ASTM D6693 Type IV, D1004, and D4833, adapting to slight ground movements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCareful Moltexo manufacturing:\u003c\/strong\u003e Professional-grade virgin polymer, controlled production processes, and verified ASTM tests for each gauge.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInert material:\u003c\/strong\u003e Suitable for aquaculture, fish farming, and potable water storage, without toxic migration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications and Uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLining of \u003cstrong\u003eartificial lakes\u003c\/strong\u003e, agricultural reservoirs, fish ponds, and water storage tanks.\u003c\/li\u003e\n  \u003cli\u003eWaterproofing of cisterns, irrigation canals, and drainage trenches on farms and agro-industrial projects.\u003c\/li\u003e\n  \u003cli\u003eSecondary containment in industrial fuel or chemical tanks.\u003c\/li\u003e\n  \u003cli\u003eLandfill sealing and \u003cstrong\u003evapor barrier\u003c\/strong\u003e in foundations and concrete slabs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and Durability\u003c\/h3\u003e\n\u003cp\u003eEach variant has internationally referenced ASTM tests: 800% elongation at break (ASTM D6693 Type IV), ESCR stress cracking resistance of 300 h (ASTM D5397), and 50% OIT retention after 1600 h of UV aging (ASTM D3895 \/ D5885). This is the technical level that separates a long-life liner from a generic black plastic for temporary use. Moltexo also controls the minimum individual thickness with a -10% tolerance on each roll, a requirement that simply does not apply to low-cost materials.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #F3F6F3; padding: clamp(14px, 4vw, 18px); margin-top: 20px; font-size: 0.9em; color: #555555; border-radius: 8px;\"\u003e\n  \u003cstrong style=\"color: #006902;\"\u003eAlso known as:\u003c\/strong\u003e\n  \u003cstrong\u003eTechnical:\u003c\/strong\u003e HDPE geomembrane, impermeable sheet, HDPE liner, smooth geomembrane, containment membrane, high-density polyethylene, geomembrane for aquaculture, HDPE vapor barrier.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e black plastic for ponds, black plastic for covering, plastic for lakes, pond tarp, slab plastic, thick liner-type plastic, black polyethylene plastic for construction.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e HDPE geomembrane (MX, CO, AR), pond liner (USA), HDPE liner, impermeable membrane, smooth geomembrane (LATAM).\n\u003c\/div\u003e","brand":"MOLTEXO","offers":[{"title":"Smooth and black \/ 0.1 mm (Gauge 400) \/ Roll 2 m (6.6 ft) wide and 50 m (164 ft) long","offer_id":52651867472200,"sku":"738426","price":12420.0,"currency_code":"DOP","in_stock":true},{"title":"Smooth and black \/ 0.2 mm (Gauge 800) \/ Roll 2 m (6.6 ft) wide and 50 m (164 ft) long","offer_id":51803392475464,"sku":"341532","price":24840.0,"currency_code":"DOP","in_stock":true},{"title":"Smooth and black \/ 0.5 mm (Gauge 2000) \/ Roll 5.8 m (19 ft) wide and 100 m (328 ft) long","offer_id":52249427542344,"sku":"354643","price":180750.0,"currency_code":"DOP","in_stock":true},{"title":"Smooth and black \/ 1 mm (Gauge 4000) \/ Roll 5.8 m (19 ft) wide and 100 m (328 ft) long","offer_id":52249366692168,"sku":"754313","price":361263.0,"currency_code":"DOP","in_stock":true},{"title":"Smooth and black \/ 1.5 mm (Gauge 6000) \/ Roll 5.8 m (19 ft) wide and 100 m (328 ft) long","offer_id":52249427575112,"sku":"345346","price":536700.0,"currency_code":"DOP","in_stock":true},{"title":"Smooth and black \/ 2 mm (Gauge 8000) \/ Roll 5.8 m (19 ft) wide and 100 m (328 ft) long","offer_id":52651913871688,"sku":"723460","price":720000.0,"currency_code":"DOP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/rollo-geomembrana-hdpe-negro-construccion-rd.png?v=1778208692","url":"https:\/\/dodom.com\/en\/products\/high-density-polyethylene-hdpe-geomembrane","provider":"Dodom","version":"1.0","type":"link"}
