Incorpora polietileno como capa impermeable central, combinado con tecido non tecido de polipropileno ou fibra de poli\u00e9ster de alta resistencia na superficie, xunto con aditivos como barreiras de luz ultravioleta e axentes antienvellecemento. Esta membrana prod\u00facese mediante un proceso de extrusi\u00f3n \u00fanico utilizando equipos especializados, o que resulta nunha estrutura multicapa que integra a superficie do tecido non tecido coa cara inferior de polietileno-polipropileno. As especificaci\u00f3ns est\u00e1ndar incl\u00faen grosores que van dende 0,7 mm ata 1,2 mm, lonxitudes de 50 m ou 100 m por rolo e unha anchura de 1,2 m. As propiedades com\u00fans reportadas para membranas de polietileno-polipropileno similares incl\u00faen a resistencia ao envellecemento, \u00e1 intemperie e \u00e1 corrosi\u00f3n, as\u00ed como a resistencia \u00e1 tracci\u00f3n axeitada para aplicaci\u00f3ns de construci\u00f3n. Estes materiais \u00fasanse normalmente en tellados, sotos, ba\u00f1os, t\u00faneles, presas e outros proxectos civ\u00eds ou industriais que requiren protecci\u00f3n contra a humidade e impermeabilidade. A instalaci\u00f3n adoita implicar a uni\u00f3n directa con cemento ou outros substratos durante a construci\u00f3n.<\/p>\n<table style=\"width: 100%; text-align: center; border-radius: 8px; overflow: hidden; background-color: #f8fafc;\" border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\n<tbody>\n<tr>\n<td style=\"background-color: #eef2f7;\">Espesor (mm)<\/td>\n<td>0,7\uff5e1,2<\/td>\n<td style=\"background-color: #eef2f7;\">Lonxitude (m)<\/td>\n<td>50 \/ 100<\/td>\n<td style=\"background-color: #eef2f7;\">Largura (m)<\/td>\n<td>1.2<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eef2f7;\">Superficie<\/td>\n<td>tecido non tecido<\/td>\n<td style=\"background-color: #eef2f7;\">Cara inferior<\/td>\n<td colspan=\"3\">Polietileno polipropileno<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1401 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-scaled.webp\" alt=\"Membrana impermeable de pol\u00edmero JY-GBL Membrana impermeabilizante de polietileno e polipropileno\" width=\"2560\" height=\"1810\" srcset=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-scaled.webp 2560w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-1280x905.webp 1280w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-980x693.webp 980w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-480x339.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 2560px, 100vw\" \/><\/p>\n<h3 dir=\"auto\">Caracter\u00edsticas do produto<\/h3>\n<ul dir=\"auto\">\n<li><strong>Propiedades f\u00edsicas<\/strong>Presenta resistencia ao envellecemento, \u00e1 oxidaci\u00f3n e \u00e1 corrosi\u00f3n.

Siga sempre os c\u00f3digos de construci\u00f3n locais, as especificaci\u00f3ns do fabricante e os protocolos de seguridade. As ferramentas que se requiren normalmente incl\u00faen unha navalla, rolos, paletas e aplicadores de adhesivo. Aseg\u00farese de que o substrato sexa estruturalmente s\u00f3lido antes de comezar.<\/p>\n<ul>\n<li><b>Preparaci\u00f3n da superficie:<\/b> Limpa a fondo a superficie da base para eliminar a sucidade, o po, os residuos e calquera material solto. Usa unha esponxa ou vasoira h\u00famida para limpar. A superficie debe estar libre de aceites, graxa ou contaminantes. Para substratos de cart\u00f3n xeso ou porosos, aplica unha imprimaci\u00f3n compatible e deixa que seque completamente. Este paso garante unha adhesi\u00f3n axeitada e evita problemas durante a aplicaci\u00f3n.<\/li>\n<li><b>Aplicaci\u00f3n de imprimaci\u00f3n ou adhesivo:<\/b> Prepare un adhesivo a base de poliuretano ou un material de uni\u00f3n de cemento polim\u00e9rico segundo as proporci\u00f3ns especificadas (normalmente mest\u00farase in situ). Apl\u00edqueo uniformemente sobre a capa base cunha esp\u00e1tula, centr\u00e1ndose en zonas complexas como esquinas, ra\u00edces de tubaxes e bordos. Deixe que o adhesivo se pegue se \u00e9 necesario, pero contin\u00fae mentres a\u00ednda estea fresco para a uni\u00f3n.<\/li>\n<li><b>Tratamento de \u00e1rea especial: <\/b>En zonas de impermeabilizaci\u00f3n vulnerables como penetraci\u00f3ns de tubaxes, xuntas de expansi\u00f3n, esquinas internas\/externas en chans e paredes, aplique unha capa adicional de <a href=\"https:\/\/great-ocean-waterproof.com\/gl\/polyurethane-waterproof-coating\/\">revestimento de poliuretano<\/a> ou selante compatible como reforzo. Para tubaxes, use colares ou selantes precortados se os ten; incl\u00faaos no adhesivo. Corte a membrana para que se axuste a estas caracter\u00edsticas, asegur\u00e1ndose de que non haxa ocos.<\/li>\n<li><b>Colocaci\u00f3n de membranas: <\/b>Desenrola a membrana comezando polo punto m\u00e1is baixo ou bordo inferior, traballando cara arriba para evitar que quede aire atrapado. Ali\u00f1aa con coidado e incl\u00fadea no adhesivo usando un rodillo ou unha llana para eliminar as bolsas de aire e garantir un contacto completo. Para paredes ou superficies verticais, comeza pola base e solapa as l\u00e1minas seguintes. Mant\u00e9n un grosor uniforme durante a colocaci\u00f3n.<\/li>\n<li><b>Manexo de xuntas e solapamentos:<\/b> Superp\u00f3n os rolos adxacentes polo menos de 50 a 150 mm (2 a 6 polgadas) para crear xuntas seguras. Fixa temporalmente as superposici\u00f3ns con cinta adhesiva ou puntos de material de uni\u00f3n. Despois, aplica un adhesivo especializado para xuntas de solape ao longo das xuntas e, a continuaci\u00f3n, un selante para o peche final. Aplica o rolo sobre as xuntas para garantir que estean planas e estancas. Preste atenci\u00f3n \u00e1s superposici\u00f3ns e penetraci\u00f3ns dos extremos para un selado completo.<\/li>\n<li><b>Acabado e inspecci\u00f3n:<\/b> Despois da instalaci\u00f3n, inspeccione se hai burbullas, engurras ou zonas sen selar. Repare calquera defecto inmediatamente con parches de membrana e selante adicionais. Deixe que o sistema cure segundo as instruci\u00f3ns do adhesivo antes de aplicar acabados como azulexos ou recheos. En condici\u00f3ns de humidade, a instalaci\u00f3n pode continuar en superficies sen charcos, pero aseg\u00farese de que non haxa auga estancada.<\/li>\n<li><b>Notas posteriores \u00e1 instalaci\u00f3n:<\/b> Protexa a membrana instalada de danos durante a construci\u00f3n posterior. Para aplicaci\u00f3ns de tellas, use morteiros de capa fina sen modificar ou modificados directamente sobre a membrana. Comprobe se hai fugas se \u00e9 o caso e almacene os rolos non utilizados nun lugar seco e fresco.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1409 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-scaled.webp\" alt=\"Membrana impermeable de pol\u00edmero JY-GBL Membrana impermeabilizante de polietileno PE PP\" width=\"2560\" height=\"2560\" srcset=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-scaled.webp 2560w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-1280x1280.webp 1280w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-980x980.webp 980w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 2560px, 100vw\" \/><\/p>\n<h3 dir=\"auto\">Comparaci\u00f3n: Membrana impermeable de pol\u00edmero JY-GBL (polietileno polipropileno) fronte a membranas de TPO<\/h3>\n<p dir=\"auto\">A JY-GBL \u00e9 unha membrana impermeabilizante composta feita de polietileno como capa central con polipropileno ou tecido non tecido de poli\u00e9ster, aditivos para a resistencia aos raios UV e ao envellecemento, e producida por extrusi\u00f3n.

It incorporates polyethylene as the core waterproof layer, combined with high-strength polypropylene or polyester fiber non-woven fabric on the surface, along with additives such as ultraviolet light barriers and anti-aging agents.\r\n\r\nThis membrane is produced through a one-time extrusion process using specialized equipment, resulting in a multi-layer structure that integrates the non-woven fabric surface with the polyethylene-polypropylene underface. Standard specifications include thicknesses ranging from 0.7 mm to 1.2 mm, lengths of 50 m or 100 m per roll, and a width of 1.2 m.\r\n\r\nCommon properties reported for similar polyethylene-polypropylene membranes include resistance to aging, weathering, and corrosion, as well as tensile strength suitable for construction applications. These materials are typically used in roofing, basements, bathrooms, tunnels, dams, and other civil or industrial projects requiring moisture protection and impermeability. Installation often involves direct bonding with cement or other substrates during construction.\r\n<table style=\"width: 100%;text-align: center;border-radius: 8px;overflow: hidden;background-color: #f8fafc\" border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\r\n<tbody>\r\n<tr>\r\n<td style=\"background-color: #eef2f7\">Thickness(mm)<\/td>\r\n<td>0.7\uff5e1.2<\/td>\r\n<td style=\"background-color: #eef2f7\">Length(m)<\/td>\r\n<td>50 \/ 100<\/td>\r\n<td style=\"background-color: #eef2f7\">Width(m)<\/td>\r\n<td>1.2<\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"background-color: #eef2f7\">Surface<\/td>\r\n<td>Non-woven fabric<\/td>\r\n<td style=\"background-color: #eef2f7\">Underface<\/td>\r\n<td colspan=\"3\">Polyethylene polypropylene<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<img class=\"size-full wp-image-1401 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-Polyethylene-Polypropylene-Waterproofing-Membrane_1_1-scaled.webp\" alt=\"JY-GBL Polymer Waterproof Membrane Polyethylene Polypropylene Waterproofing Membrane\" width=\"2560\" height=\"1810\" \/>\r\n<h3 dir=\"auto\">Product Features<\/h3>\r\n<ul dir=\"auto\">\r\n \t<li><strong>Physical Properties<\/strong>: Exhibits anti-aging, anti-oxidation, and corrosion resistance.

Always follow local building codes, manufacturer specifications, and safety protocols. Tools typically required include a utility knife, rollers, trowels, and adhesive applicators. Ensure the substrate is structurally sound before beginning.\r\n<ul>\r\n \t<li><b>Surface Preparation:<\/b> Thoroughly clean the base surface to remove dirt, dust, debris, and any loose materials. Use a damp sponge or broom for cleaning. The surface should be free of oils, grease, or contaminants. For drywall or porous substrates, apply a compatible primer and allow it to dry fully. This step ensures proper adhesion and prevents issues during application.<\/li>\r\n \t<li><b>Primer or Adhesive Application:<\/b> Prepare a polyurethane-based adhesive or polymer cement bonding material according to proportions specified (typically mixed on-site). Apply it evenly across the base layer using a trowel, focusing on complex areas such as corners, pipe roots, and edges. Allow the adhesive to tack up if required, but proceed while it's still fresh for bonding.<\/li>\r\n \t<li><b>Special Area Treatment: <\/b>In vulnerable waterproofing zones like pipe penetrations, expansion joints, internal\/external corners on grounds and walls, apply an additional layer of <a href=\"https:\/\/great-ocean-waterproof.com\/polyurethane-waterproof-coating\/\">polyurethane coating<\/a> or compatible sealant as reinforcement. For pipes, use pre-cut collars or seals if available; embed them into the adhesive. Cut the membrane to fit around these features, ensuring no gaps.<\/li>\r\n \t<li><b>Membrane Laying: <\/b>Unroll the membrane starting from the lowest point or bottom edge, working upwards to avoid trapping air. Align it carefully and embed it into the adhesive using a roller or float to remove air pockets and ensure full contact. For walls or vertical surfaces, start at the base and overlap subsequent sheets. Maintain uniform thickness during placement.<\/li>\r\n \t<li><b>Joint and Overlap Handling:<\/b> Overlap adjacent rolls by at least 2-6 inches (50-150 mm) to create secure seams. Temporarily fix overlaps with adhesive tape or spots of bonding material. Then, apply a specialized lap joint adhesive along the seams, followed by a sealant for final closure. Roll over the joints to ensure they are flat and watertight. Pay attention to end laps and penetrations for complete sealing.<\/li>\r\n \t<li><b>Finishing and Inspection:<\/b> After installation, inspect for bubbles, wrinkles, or unsealed areas. Repair any defects immediately with additional membrane patches and sealant. Allow the system to cure as per adhesive instructions before applying finishes like tiles or backfill. In damp conditions, installation can proceed on non-puddled surfaces, but ensure no standing water.<\/li>\r\n \t<li><b>Post-Installation Notes:<\/b> Protect the installed membrane from damage during subsequent construction. For tile applications, use unmodified or modified thin-set mortars directly over the membrane. Test for leaks if applicable, and store unused rolls in a dry, cool place.<\/li>\r\n<\/ul>\r\n<img class=\"size-full wp-image-1409 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2026\/01\/JY-GBL-Polymer-Waterproof-Membrane-PE-PP-Polyethylene-Polypropylene-Waterproofing-Membrane-2_1-scaled.webp\" alt=\"JY-GBL Polymer Waterproof Membrane PE PP Polyethylene Polypropylene Waterproofing Membrane\" width=\"2560\" height=\"2560\" \/>\r\n<h3 dir=\"auto\">Comparison: JY-GBL Polymer Waterproof Membrane (Polyethylene Polypropylene) vs. TPO Membranes<\/h3>\r\n<p dir=\"auto\">The JY-GBL is a composite waterproofing membrane made from polyethylene as the core layer with polypropylene or polyester non-woven fabric, additives for UV and aging resistance, and produced via extrusion. In contrast, TPO (Thermoplastic Polyolefin) membranes are typically single-ply sheets blending polypropylene and ethylene-propylene rubber, often reinforced with polyester scrim.

Choice depends on project specifics like exposure to chemicals or installation conditions.<\/p>\r\n\r\n<h2 dir=\"auto\">Customer Reviews<\/h2>\r\n<b>John R., USA (Contractor, Basement Waterproofing Project)<\/b>\r\nI used this membrane for a basement retrofit in a humid area. It adhered well to the damp concrete without much prep, and after a year, no signs of seepage despite heavy rains. The rolls were straightforward to handle, though I needed extra adhesive for the overlaps. Solid choice for underground work, but plan for some trimming around pipes.\r\n\r\n<b>Elena S., Germany (Engineer, Tunnel Lining)<\/b>\r\nApplied this in a small tunnel project where corrosion resistance was key. The material held up during installation on uneven surfaces, and its puncture resistance helped with the rocky base. We've monitored it for six months\u2014no issues with water ingress. It's not the cheapest option, but it performs as expected in industrial settings.\r\n\r\n<b>Michael T., Australia (Homeowner, Roof Application)<\/b>\r\nInstalled this on my flat roof extension. It was flexible enough to conform to the contours, and the UV barrier seems to be doing its job under the sun. No leaks after recent storms, but I had to double-check the seams to ensure they were sealed properly. Good for outdoor exposure, though I'd recommend professional help for larger areas.\r\n\r\n<b>Aiko H., Japan (Builder, Water Storage Tank)<\/b>\r\nWe used it for lining a municipal water tank. The non-toxic properties were important for compliance, and it bonded evenly with the polymer cement. After testing, it contained water without any deformation. Handling was easy, but the width limited coverage in tight spaces\u2014had to order extra rolls.\r\n\r\n<b>Carlos M., Mexico (Landscaper, Green Roof System)<\/b>\r\nPut this under a rooftop garden to block root penetration. It worked fine against the plants' growth over eight months, and the anti-aging additives appear to maintain its integrity in hot weather. Installation went smoothly on the prepared surface, though overlaps required careful attention to avoid gaps. Reliable for planting applications.\r\n\r\n<img class=\"size-full wp-image-962 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/customer-feedback_1.webp\" alt=\"customer feedback\" width=\"2245\" height=\"1587\" \/>\r\n<h2>About Our Factory: Great Ocean Waterproof<\/h2>\r\n<b>Company Overview<\/b>\r\nGreat Ocean Waterproof Technology Co., Ltd.
