Incorpora polietil\u00e8 com a capa impermeable principal, combinat amb teixit no teixit de polipropil\u00e8 o fibra de poli\u00e8ster d'alta resist\u00e8ncia a la superf\u00edcie, juntament amb additius com barreres de llum ultraviolada i agents antienvelliment. Aquesta membrana es produeix mitjan\u00e7ant un proc\u00e9s d'extrusi\u00f3 \u00fanic utilitzant equips especialitzats, donant com a resultat una estructura multicapa que integra la superf\u00edcie del teixit no teixit amb la cara inferior de polietil\u00e8-polipropil\u00e8. Les especificacions est\u00e0ndard inclouen gruixos que van des de 0,7 mm fins a 1,2 mm, longituds de 50 m o 100 m per rotlle i una amplada d'1,2 m. Les propietats comunes reportades per a membranes de polietil\u00e8-polipropil\u00e8 similars inclouen la resist\u00e8ncia a l'envelliment, la intemp\u00e8rie i la corrosi\u00f3, aix\u00ed com la resist\u00e8ncia a la tracci\u00f3 adequada per a aplicacions de construcci\u00f3. Aquests materials s'utilitzen normalment en cobertes, soterranis, banys, t\u00fanels, preses i altres projectes civils o industrials que requereixen protecci\u00f3 contra la humitat i impermeabilitat. La instal\u00b7laci\u00f3 sovint implica la uni\u00f3 directa amb ciment o altres substrats durant la construcci\u00f3.<\/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;\">Gruix (mm)<\/td>\n<td>0,7\uff5e1,2<\/td>\n<td style=\"background-color: #eef2f7;\">Longitud (m)<\/td>\n<td>50 \/ 100<\/td>\n<td style=\"background-color: #eef2f7;\">Amplada (m)<\/td>\n<td>1.2<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eef2f7;\">Superf\u00edcie<\/td>\n<td>Teixit no teixit<\/td>\n<td style=\"background-color: #eef2f7;\">Cara inferior<\/td>\n<td colspan=\"3\">Polietil\u00e8 polipropil\u00e8<\/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\u00edmer JY-GBL Membrana impermeabilitzant de polietil\u00e8 i polipropil\u00e8\" 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\u00edstiques del producte<\/h3>\n<ul dir=\"auto\">\n<li><strong>Propietats f\u00edsiques<\/strong>Presenta resist\u00e8ncia a l'envelliment, a l'oxidaci\u00f3 i a la corrosi\u00f3.

Seguiu sempre els codis de construcci\u00f3 locals, les especificacions del fabricant i els protocols de seguretat. Les eines que normalment es necessiten inclouen un ganivet multiusos, corrons, paletes i aplicadors d'adhesiu. Assegureu-vos que el substrat sigui estructuralment s\u00f2lid abans de comen\u00e7ar.<\/p>\n<ul>\n<li><b>Preparaci\u00f3 de la superf\u00edcie:<\/b> Netegeu a fons la superf\u00edcie de la base per eliminar la brut\u00edcia, la pols, les restes i qualsevol material solt. Utilitzeu una esponja o una escombra humida per netejar. La superf\u00edcie ha d'estar lliure d'olis, greixos o contaminants. Per a substrats de guix o porosos, apliqueu una imprimaci\u00f3 compatible i deixeu-la assecar completament. Aquest pas garanteix una adher\u00e8ncia correcta i evita problemes durant l'aplicaci\u00f3.<\/li>\n<li><b>Aplicaci\u00f3 d'imprimaci\u00f3 o adhesiu:<\/b> Prepareu un adhesiu a base de poliuret\u00e0 o un material d'uni\u00f3 de ciment polim\u00e8ric segons les proporcions especificades (normalment es barreja in situ). Apliqueu-lo uniformement sobre la capa base amb una paleta, centrant-vos en zones complexes com ara cantonades, arrels de canonades i vores. Deixeu que l'adhesiu s'enganxi si cal, per\u00f2 continueu mentre encara est\u00e0 fresc per a l'uni\u00f3.<\/li>\n<li><b>Tractament d'\u00c0rea Especial: <\/b>En zones d'impermeabilitzaci\u00f3 vulnerables com ara penetracions de canonades, juntes de dilataci\u00f3, cantonades internes\/externes en terres i parets, apliqueu una capa addicional de <a href=\"https:\/\/great-ocean-waterproof.com\/ca\/polyurethane-waterproof-coating\/\">recobriment de poliuret\u00e0<\/a> o segellador compatible com a refor\u00e7. Per a les canonades, utilitzeu collars o segells pretallats si n'hi ha; incrusteu-los a l'adhesiu. Talleu la membrana perqu\u00e8 s'adapti a aquestes caracter\u00edstiques, assegurant-vos que no hi hagi buits.<\/li>\n<li><b>Col\u00b7locaci\u00f3 de membranes: <\/b>Desenrotlleu la membrana comen\u00e7ant des del punt m\u00e9s baix o la vora inferior, treballant cap amunt per evitar que quedi aire atrapat. Alineeu-la amb cura i incrusteu-la a l'adhesiu amb un corr\u00f3 o una llana per eliminar les bosses d'aire i assegurar un contacte complet. Per a parets o superf\u00edcies verticals, comenceu per la base i superposeu les l\u00e0mines posteriors. Manteniu un gruix uniforme durant la col\u00b7locaci\u00f3.<\/li>\n<li><b>Manipulaci\u00f3 de juntes i solapaments:<\/b> Superposeu els rotlles adjacents almenys de 50 a 150 mm (2-6 polzades) per crear juntes segures. Fixeu temporalment les superposicions amb cinta adhesiva o punts de material d'uni\u00f3. A continuaci\u00f3, apliqueu un adhesiu especialitzat per a juntes de solapament al llarg de les juntes, seguit d'un segellador per al tancament final. Apliqueu el corr\u00f3 sobre les juntes per assegurar-vos que siguin planes i estanques. Presteu atenci\u00f3 a les superposicions dels extrems i a les penetracions per a un segellat complet.<\/li>\n<li><b>Acabat i inspecci\u00f3:<\/b> Despr\u00e9s de la instal\u00b7laci\u00f3, inspeccioneu si hi ha bombolles, arrugues o zones sense segellar. Repareu qualsevol defecte immediatament amb pegats de membrana i segellador addicionals. Deixeu que el sistema s'assequi segons les instruccions de l'adhesiu abans d'aplicar acabats com ara rajoles o farciments. En condicions d'humitat, la instal\u00b7laci\u00f3 es pot continuar en superf\u00edcies sense tolls, per\u00f2 assegureu-vos que no hi hagi aigua estancada.<\/li>\n<li><b>Notes posteriors a la instal\u00b7laci\u00f3:<\/b> Protegiu la membrana instal\u00b7lada de danys durant la construcci\u00f3 posterior. Per a aplicacions de rajoles, utilitzeu morters de capa fina sense modificar o modificats directament sobre la membrana. Comproveu si hi ha fuites si escau i guardeu els rotlles no utilitzats en un lloc sec i fresc.<\/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\u00edmer JY-GBL PE PP Membrana impermeabilitzant de polietil\u00e8 i polipropil\u00e8\" 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\u00f3: Membrana impermeable de pol\u00edmer JY-GBL (polietil\u00e8 polipropil\u00e8) vs. membranes TPO<\/h3>\n<p dir=\"auto\">La JY-GBL \u00e9s una membrana impermeabilitzant composta feta de polietil\u00e8 com a capa central amb polipropil\u00e8 o teixit no teixit de poli\u00e8ster, additius per a la resist\u00e8ncia als raigs UV i a l'envelliment, i produ\u00efda per extrusi\u00f3.

Es va adherir b\u00e9 al formig\u00f3 humit sense gaire preparaci\u00f3 i, despr\u00e9s d'un any, no hi havia signes de filtracions malgrat les fortes pluges.

El material va aguantar durant la instal\u00b7laci\u00f3 en superf\u00edcies irregulars i la seva resist\u00e8ncia a la perforaci\u00f3 va ajudar amb la base rocosa. L'hem monitoritzat durant sis mesos: no hi ha hagut problemes d'entrada d'aigua.

Era prou flexible per adaptar-se als contorns i la barrera UV sembla que fa la seva feina sota el sol. No hi ha fuites despr\u00e9s de les tempestes recents, per\u00f2 vaig haver de comprovar dues vegades les juntes per assegurar-me que estaven ben segellades. \u00c9s bo per a l'exposici\u00f3 a l'aire lliure, tot i que recomanaria ajuda professional per a zones m\u00e9s grans. <b>Aiko H., Jap\u00f3 (Constructor, Dip\u00f2sit d'emmagatzematge d'aigua)<\/b> El vam fer servir per revestir un dip\u00f2sit d'aigua municipal.

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.
