{"product_id":"poly-lock","title":"Poly Lock","description":"\u003cp\u003eCreating a watertight seal between a concrete structure and an HDPE geomembrane in auditable hydraulic works such as oxidation ponds, sanitary landfills, industrial tanks, and treatment plants, where direct welding to concrete is impossible and mechanical systems with bolts can fail due to sealing leaks, requires an anchor profile embedded in virgin HDPE with an exposed face for extrusion welding. This Poly Lock—also known as \u003cstrong\u003eE-profile\u003c\/strong\u003e, HDPE anchor profile for concrete, or E-lock—is manufactured by MOLTEXO in virgin HDPE, dimensions 100×40 mm × 3 m long, in packs of 10 units, designed for lining tanks, ponds, canals, landfills, and hydraulic works with auditable sealing criteria.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMechanical anchoring to fresh concrete:\u003c\/strong\u003e the rear anchor \"fingers\" of the profile are embedded in the concrete mass during curing, creating immovable mechanical retention that withstands hydrostatic pressure and thrusts throughout the useful life of the structure.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVirgin HDPE for monolithic welding:\u003c\/strong\u003e the Poly Lock material is identical to that of common HDPE geomembranes, a critical condition for extrusion welding to create a complete molecular bond where the profile and geomembrane become a single watertight piece.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical resistance in hydraulic works:\u003c\/strong\u003e HDPE withstands contact with wastewater, landfill leachates, aggressive chemicals typical of treatment plants, mild alkalis and acids, conditions for decades of useful life in continuous hydraulic operation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmooth exposed face ready for welding:\u003c\/strong\u003e after demolding, the exposed face of the Poly Lock is perfectly accessible for extrusion welding with an HDPE filler rod, a condition for professional operation without additional surface preparation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUV resistance during pre-lining exposure:\u003c\/strong\u003e virgin HDPE withstands exposure to the Caribbean sun during the period between demolding and geomembrane welding without degradation or loss of welding properties.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications and Uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLining of tanks, irrigation canals, water reservoirs, and industrial reservoirs with HDPE geomembrane.\u003c\/li\u003e\n  \u003cli\u003eSealing of bottoms and slopes in oxidation ponds, sanitary landfills, and water treatment plants.\u003c\/li\u003e\n  \u003cli\u003eJoints between concrete and geomembrane in dikes, dams, tunnels, and hydraulic works with contractual auditing.\u003c\/li\u003e\n  \u003cli\u003eProtection of concrete structures exposed to corrosive agents in industrial plants and chemical works.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and Durability\u003c\/h3\u003e\n\u003cp\u003eAn inexpensive Poly Lock fails in two ways: the HDPE is not virgin but low-quality recycled (which produces weak welds with a risk of leakage under auditable hydrostatic pressure) and the rear anchors are short or ineffective (which causes the profile to loosen from the concrete under backfill thrust or water pressure, compromising watertightness). MOLTEXO works with virgin HDPE and a calibrated anchor design, which distinguishes an E-profile for auditable hydraulic works from a generic consumable that fails in the first watertightness tests.\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 Poly Lock, E-profile, HDPE anchor profile, embedded HDPE batten, geomembrane embed strip.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e Poly Lock, perfil E, regleta para geomembrana, perfil de anclaje.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e Poly Lock (USA), HDPE batten strip (USA), embed strip (USA), perfil de anclaje HDPE (LATAM), profilé d'ancrage (FR), regleta de fijación (LATAM, ES).\n\u003c\/div\u003e","brand":"MOLTEXO","offers":[{"title":"100 mm (4 in) wide and 40 mm (1.6 in) high \/ 3 m (9.84 ft) \/ Pack of 10 Poly Locks","offer_id":52249730875720,"sku":"765390","price":74700.0,"currency_code":"DOP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/perfil-poly-lock-hdpe-geomembranas-santo-domingo.png?v=1771869504","url":"https:\/\/dodom.com\/en\/products\/poly-lock-buckle","provider":"Dodom","version":"1.0","type":"link"}
