Ia menggabungkan polietilena sebagai lapisan kalis air teras, digabungkan dengan fabrik bukan tenunan polipropilena atau gentian poliester berkekuatan tinggi pada permukaannya, berserta bahan tambahan seperti penghalang cahaya ultraungu dan agen anti-penuaan. Membran ini dihasilkan melalui proses penyemperitan sekali sahaja menggunakan peralatan khusus, menghasilkan struktur berbilang lapisan yang mengintegrasikan permukaan fabrik bukan tenunan dengan bahagian bawah polietilena-polipropilena. Spesifikasi standard termasuk ketebalan antara 0.7 mm hingga 1.2 mm, panjang 50 m atau 100 m setiap gulungan dan lebar 1.2 m. Ciri-ciri biasa yang dilaporkan untuk membran polietilena-polipropilena yang serupa termasuk ketahanan terhadap penuaan, luluhawa dan kakisan, serta kekuatan tegangan yang sesuai untuk aplikasi pembinaan. Bahan-bahan ini biasanya digunakan dalam bumbung, ruang bawah tanah, bilik mandi, terowong, empangan dan projek awam atau perindustrian lain yang memerlukan perlindungan kelembapan dan kebolehtelapan. Pemasangan selalunya melibatkan ikatan langsung dengan simen atau substrat lain semasa pembinaan.<\/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;\">Ketebalan (mm)<\/td>\n<td>0.7\uff5e1.2<\/td>\n<td style=\"background-color: #eef2f7;\">Panjang(m)<\/td>\n<td>50 \/ 100<\/td>\n<td style=\"background-color: #eef2f7;\">Lebar (m)<\/td>\n<td>1.2<\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #eef2f7;\">Permukaan<\/td>\n<td>Fabrik bukan tenunan<\/td>\n<td style=\"background-color: #eef2f7;\">Bahagian bawah muka<\/td>\n<td colspan=\"3\">Polietilena polipropilena<\/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=\"Membran Kalis Air Polimer JY-GBL Membran Kalis Air Polietilena Polipropilena\" 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\">Ciri-ciri Produk<\/h3>\n<ul dir=\"auto\">\n<li><strong>Sifat Fizikal<\/strong>: Mempamerkan rintangan anti-penuaan, anti-pengoksidaan dan kakisan.

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.<\/p>\n<ul>\n<li><b>Penyediaan Permukaan:<\/b> Bersihkan permukaan asas dengan teliti untuk menghilangkan kotoran, habuk, serpihan dan sebarang bahan yang longgar. Gunakan span atau penyapu lembap untuk membersihkan. Permukaan hendaklah bebas daripada minyak, gris atau bahan cemar. Untuk papan gipsum atau substrat berliang, sapukan primer yang serasi dan biarkan ia kering sepenuhnya. Langkah ini memastikan lekatan yang betul dan mencegah masalah semasa penggunaan.<\/li>\n<li><b>Penggunaan Primer atau Pelekat:<\/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>\n<li><b>Rawatan Kawasan Khas: <\/b>Dalam zon kalis air yang terdedah seperti penembusan paip, sambungan pengembangan, sudut dalaman\/luaran pada permukaan dan dinding, sapukan lapisan tambahan <a href=\"https:\/\/great-ocean-waterproof.com\/ms\/polyurethane-waterproof-coating\/\">salutan poliuretana<\/a> atau pengedap yang serasi sebagai tetulang. Untuk paip, gunakan kolar atau pengedap yang telah dipotong terlebih dahulu jika ada; tanamkannya ke dalam pelekat. Potong membran agar sesuai di sekeliling ciri-ciri ini, pastikan tiada jurang.<\/li>\n<li><b>Pemasangan Membran: <\/b>Buka gulungan membran bermula dari titik terendah atau tepi bawah, bergerak ke atas untuk mengelakkan udara terperangkap. Sejajarkannya dengan berhati-hati dan masukkan ke dalam pelekat menggunakan penggelek atau pelampung untuk mengeluarkan poket udara dan memastikan sentuhan penuh. Untuk dinding atau permukaan menegak, mulakan di pangkal dan tumpang tindih helaian berikutnya. Kekalkan ketebalan yang seragam semasa peletakan.<\/li>\n<li><b>Pengendalian Sambungan dan Pertindihan:<\/b> Bertindih gulungan bersebelahan sekurang-kurangnya 2-6 inci (50-150 mm) untuk mewujudkan lipit yang kukuh. Pasangkan lipit sementara dengan pita pelekat atau tompok bahan pengikat. Kemudian, sapukan pelekat sambungan riba khusus di sepanjang lipit, diikuti dengan pengedap untuk penutupan terakhir. Gulungkan sambungan untuk memastikan ia rata dan kedap air. Beri perhatian pada pusingan hujung dan penembusan untuk pengedapan yang lengkap.<\/li>\n<li><b>Kemasan dan Pemeriksaan:<\/b> Selepas pemasangan, periksa gelembung, kedutan atau kawasan yang tidak ditutup. Segera baiki sebarang kecacatan dengan tampalan membran dan pengedap tambahan. Biarkan sistem mengeras mengikut arahan pelekat sebelum menggunakan kemasan seperti jubin atau timbusan. Dalam keadaan lembap, pemasangan boleh diteruskan pada permukaan yang tidak berlumpur, tetapi pastikan tiada air bertakung.<\/li>\n<li><b>Nota Pasca Pemasangan:<\/b> Lindungi membran yang dipasang daripada kerosakan semasa pembinaan berikutnya. Untuk aplikasi jubin, gunakan mortar nipis yang tidak diubah suai atau diubah suai terus di atas membran. Uji kebocoran jika berkenaan, dan simpan gulungan yang tidak digunakan di tempat yang kering dan sejuk.<\/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=\"Membran Kalis Air Polimer JY-GBL PE PP Polietilena Polipropilena Membran Kalis Air\" 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\">Perbandingan: Membran Kalis Air Polimer JY-GBL (Polietilena Polipropilena) vs. Membran TPO<\/h3>\n<p dir=\"auto\">JY-GBL ialah membran kalis air komposit yang diperbuat daripada polietilena sebagai lapisan teras dengan fabrik bukan tenunan polipropilena atau poliester, bahan tambahan untuk rintangan UV dan penuaan, dan dihasilkan melalui penyemperitan.

Ia melekat dengan baik pada konkrit lembap tanpa banyak persediaan, dan selepas setahun, tiada tanda-tanda rembesan walaupun hujan lebat. Gulungan-gulungan itu mudah dikendalikan, walaupun saya memerlukan pelekat tambahan untuk pertindihannya. Pilihan yang kukuh untuk kerja bawah tanah, tetapi rancang untuk memangkas di sekeliling paip. <b>Elena S., Jerman (Jurutera, Lapisan Terowong)<\/b> Applied 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. <b>Michael T., Australia (Pemilik Rumah, Permohonan Bumbung)<\/b> Installed 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. <b>Aiko H., Jepun (Pembina, Tangki Simpanan Air)<\/b> Kami menggunakannya untuk melapisi tangki air perbandaran. Ciri-ciri tidak toksik adalah penting untuk pematuhan, dan ia terikat sama rata dengan simen polimer. Selepas ujian, ia mengandungi air tanpa sebarang ubah bentuk. Pengendalian adalah mudah, tetapi lebarnya terhad kepada liputan di ruang yang sempit\u2014terpaksa memesan gulungan tambahan. <b>Carlos M., Mexico (Pembina Landskap, Sistem Bumbung Hijau)<\/b> Put 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.

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.

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.
