{"product_id":"geocompuesto-drenante","title":"Drainage geocomposite","description":"\u003cp\u003eReplacing bulky traditional drainage gravel layers with a thin, high-flow solution in retaining walls, basements, and green roofs where space and weight are critical, without losing hydraulic efficiency or filtration against clogging, requires a geocomposite with a three-dimensional geonet core and lateral filtering geotextiles. This drainage geocomposite —also called \u003cstrong\u003egeodrain\u003c\/strong\u003e, drainage sheet with geotextile, or macdrain— is manufactured by MOLTEXO with a geonet core between two layers of non-woven geotextile, in a 5.8 m wide and 100 m long roll, designed for retaining walls, basements, foundations, green roofs, landfills, and any professional planar drainage application.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-flow planar drainage:\u003c\/strong\u003e the three-dimensional geonet core delivers a water flow capacity that efficiently replaces traditional drainage gravel, saving excavation volume, weight on structures, and the logistical cost of aggregate transport.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated filtration against clogging:\u003c\/strong\u003e the lateral geotextiles filter fine soil particles, preventing them from entering the drainage core and obstructing the flow channels — a critical condition for the system to last decades with no maintenance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated mechanical resistance:\u003c\/strong\u003e the geocomposite withstands the compression loads of fill or surface traffic without the core being crushed, maintaining drainage capacity even under meters of soil in a retaining wall or vehicle traffic on a drainage platform.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble-sided geotextile for versatile use:\u003c\/strong\u003e both faces have filtering geotextile, which allows direct contact with soil in any orientation, removing the need to orient the material during installation and simplifying on-site logistics.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFast deployment in manageable rolls:\u003c\/strong\u003e the material is lightweight and rolls out with basic equipment, a clear advantage over gravel + pipe + geotextile systems that require deep excavation, aggregate transport, and complex maneuvers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical applications and uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVertical drainage behind retaining walls and basement walls for relief of hydrostatic pressure.\u003c\/li\u003e\n  \u003cli\u003eHorizontal drainage under foundation slabs and floor slabs in zones with high subsoil moisture.\u003c\/li\u003e\n  \u003cli\u003eGreen roofs (landscaped roofs) to evacuate excess irrigation and rainwater, preventing substrate saturation.\u003c\/li\u003e\n  \u003cli\u003eSanitary landfills, tunnels, and underground works with professional perimeter drainage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eAn economical drainage geocomposite fails on two fronts: the geonet core is thin or collapses under load (which reduces the declared flow capacity and saturates the system within a few years) and the lateral geotextiles are sparse with no effective filtration (which causes migration of fines into the core and clogs the system within months). MOLTEXO works with a structural geonet core and calibrated filtering geotextiles, which separates a professional construction geodrain from a generic composite that saturates before the first year.\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 drainage geocomposite, geodrain, drainage sheet with geotextile, geonet with geotextile, composite drainage mat.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e geocompuesto drenante, geodrén, geored con tela, panel drenante.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e drainage geocomposite (USA), geocomposite drainage (USA), macdrain (BR\/LATAM), geocomposite drenant (FR), drainage layer (USA), geodrén (LATAM, ES).\n\u003c\/div\u003e","brand":"MOLTEXO","offers":[{"title":"Non-woven geotextile + Geonet + Non-woven geotextile \/ Roll 5.8 m (19 ft) wide and 100 m (328 ft) long","offer_id":52627840598344,"sku":"746941","price":345000.0,"currency_code":"DOP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/rollo-geocompuesto-drenante-geored.png?v=1773588730","url":"https:\/\/dodom.com\/en\/products\/drainage-geocomposite","provider":"Dodom","version":"1.0","type":"link"}
