Den inkorporerer polyethylen som det centrale vandt\u00e6tte lag, kombineret med h\u00f8jstyrke polypropylen- eller polyesterfiber-non-woven stof p\u00e5 overfladen, sammen med tils\u00e6tningsstoffer s\u00e5som ultraviolette lysbarrierer og anti-aging midler. Denne membran produceres gennem en engangs-ekstruderingsproces ved hj\u00e6lp af specialudstyr, hvilket resulterer i en flerlagsstruktur, der integrerer den non-woven stofoverflade med polyethylen-polypropylen-undersiden. Standardspecifikationer inkluderer tykkelser fra 0,7 mm til 1,2 mm, l\u00e6ngder p\u00e5 50 m eller 100 m pr. rulle og en bredde p\u00e5 1,2 m. Almindelige egenskaber rapporteret for lignende polyethylen-polypropylen-membraner inkluderer modstandsdygtighed over for \u00e6ldning, vejrp\u00e5virkning og korrosion, samt tr\u00e6kstyrke egnet til byggeri. Disse materialer anvendes typisk i tagd\u00e6kning, k\u00e6ldre, badev\u00e6relser, tunneler, d\u00e6mninger og andre civile eller industrielle projekter, der kr\u00e6ver fugtbeskyttelse og uigennemtr\u00e6ngelighed. Installation involverer ofte direkte binding med cement eller andre underlag under konstruktionen.<\/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;\">Tykkelse (mm)<\/td>\n<td>0,7\uff5e1,2<\/td>\n<td style=\"background-color: #eef2f7;\">L\u00e6ngde (m)<\/td>\n<td>50 \/ 100<\/td>\n<td style=\"background-color: #eef2f7;\">Bredde (m)<\/td>\n<td>1.2<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eef2f7;\">Overflade<\/td>\n<td>Ikke-v\u00e6vet stof<\/td>\n<td style=\"background-color: #eef2f7;\">Underflade<\/td>\n<td colspan=\"3\">Polyethylenpolypropylen<\/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=\"JY-GBL Polymer Vandt\u00e6t Membran Polyethylen Polypropylen Vandt\u00e6tningsmembran\" 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\">Produktfunktioner<\/h3>\n<ul dir=\"auto\">\n<li><strong>Fysiske egenskaber<\/strong>Udviser anti-aging, antioxidation og korrosionsbestandighed.

Brug en fugtig svamp eller kost til reng\u00f8ring. Overfladen skal v\u00e6re fri for olier, fedt eller forurenende stoffer. P\u00e5 gipsv\u00e6gge eller por\u00f8se underlag skal du p\u00e5f\u00f8re en kompatibel primer og lade den t\u00f8rre helt.

Fastg\u00f8r midlertidigt overlapninger med kl\u00e6beb\u00e5nd eller pletter af limmateriale. P\u00e5f\u00f8r derefter en specialkl\u00e6bemiddel til overlapningsfuger langs samlingerne, efterfulgt af en fugemasse for endelig lukning. Rul over samlingerne for at sikre, at de er flade og vandt\u00e6tte. V\u00e6r opm\u00e6rksom p\u00e5 overlapninger og gennemf\u00f8ringer i enden for fuldst\u00e6ndig forsegling.<\/li>\n<li><b>F\u00e6rdigg\u00f8relse og inspektion:<\/b> Efter installationen skal du kontrollere for bobler, rynker eller ut\u00e6tsede omr\u00e5der. Reparer eventuelle defekter med det samme med yderligere membranlapper og fugemasse. Lad systemet h\u00e6rde i henhold til kl\u00e6bemiddelinstruktionerne, f\u00f8r du p\u00e5f\u00f8rer overfladebehandlinger som fliser eller bagfyldning.

Den kl\u00e6bede godt til den fugtige beton uden megen forberedelse, og efter et \u00e5r var der ingen tegn p\u00e5 udsivning p\u00e5 trods af kraftig regn. Rullerne var nemme at h\u00e5ndtere, selvom jeg havde brug for ekstra kl\u00e6bemiddel til overlapningerne. Et solidt valg til underjordisk arbejde, men planl\u00e6g at trimme omkring r\u00f8r. <b>Elena S., Tyskland (Ingeni\u00f8r, Tunnelforing)<\/b> Anvendte dette i et lille tunnelprojekt, hvor korrosionsbestandighed var afg\u00f8rende. Materialet holdt stand under installation p\u00e5 uj\u00e6vne overflader, og dets punkteringsmodstand hjalp med den stenede bund. Vi har overv\u00e5get det i seks m\u00e5neder \u2013 ingen problemer med vandindtr\u00e6ngning. Det er ikke den billigste l\u00f8sning, men det fungerer som forventet i industrielle omgivelser. <b>Michael T., Australien (husejer, tagmontering)<\/b> Installerede dette p\u00e5 min tilbygning til flade tage. Det var fleksibelt nok til at tilpasse sig konturerne, og UV-barrieren ser ud til at g\u00f8re sit job i solen. Ingen l\u00e6kager efter de seneste storme, men jeg m\u00e5tte dobbelttjekke samlingerne for at sikre, at de var ordentligt forseglet. God til udend\u00f8rs brug, selvom jeg vil anbefale professionel hj\u00e6lp til st\u00f8rre omr\u00e5der. <b>Aiko H., Japan (Bygger, Vandtank)<\/b> Vi brugte den til at fore en kommunal vandtank. De giftfri egenskaber var vigtige for overholdelsen af \u200b\u200breglerne, og den kl\u00e6bede j\u00e6vnt til polymercementen. Efter testning indeholdt den vand uden nogen deformation. H\u00e5ndteringen var nem, men bredden begr\u00e6nsede d\u00e6kningen i trange rum \u2013 vi m\u00e5tte bestille ekstra ruller. <b>Carlos M., Mexico (Landskabsarkitekt, Gr\u00f8nne Tagsystemer)<\/b> Placer dette under en taghave for at blokere rodindtr\u00e6ngning. Det virkede fint mod planternes v\u00e6kst i otte m\u00e5neder, og anti-aging-tils\u00e6tningsstofferne ser ud til at bevare dets integritet i varmt vejr. Installationen gik problemfrit p\u00e5 den forberedte overflade, selvom overlapninger kr\u00e6vede omhyggelig opm\u00e6rksomhed for at undg\u00e5 huller.

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.
