It is produced by extruding polyvinyl chloride (PVC) resin combined with additives such as plasticizers, stabilizers, anti-aging agents, ultraviolet absorbers, lubricants, and fillers to form a single-layer roll.<\/p>\n<p dir=\"auto\">This membrane provides a barrier against water infiltration, suitable for use in roofing, basements, tunnels, and other structural elements where durability and flexibility are required. It resists UV exposure, chemicals, and environmental wear, with a typical service life exceeding 20 years under standard conditions.<\/p>\n<p dir=\"auto\">As a pvc sheet membrane for waterproofing, it comes in thicknesses of 1.2 mm, 1.5 mm, 1.8 mm, or 2.0 mm, with a standard length of 25 meters and widths of 1.0 meter or 2.0 meters. Installation involves methods like mechanical fastening or adhesion, depending on the substrate.<\/p>\n<p dir=\"auto\">Great Ocean Waterproof, as a pvc waterproofing membrane manufacturer, supplies this product in various specifications to meet project needs. For details on pvc waterproofing membrane price, options vary based on thickness, quantity, and regional factors; inquiries can be directed to our sales team for current quotes.<\/p>\n<table

What is the difference between H, L, P, G, and GL types of PVC membrane?<\/strong> H = homogeneous (non-reinforced); L = polyester fabric scrim; P = heavy polyester scrim; G = glass-fiber scrim; GL = glass + polyester composite. Reinforced grades (L\/P\/G\/GL) are used for mechanical fastening; H is for fully adhered or ballasted systems.<\/p>\n<p dir=\"auto\"><strong>2. How long does a PVC waterproofing membrane last?<\/strong> Roofs: 20\u201330 years exposed, 30+ years under ballast or green roof. Underground: 50+ years when protected from UV and mechanical damage.<\/p>\n<p dir=\"auto\"><strong>3. Can PVC membrane be used for green\/vegetated roofs?<\/strong> Yes. All grades pass root-penetration tests (EN 13948 \/ FLL) and are suitable under soil, drainage layers, and vegetation.<\/p>\n<p dir=\"auto\"><strong>4. What installation methods are available?<\/strong><\/p>\n<ul dir=\"auto\">\n<li>Mechanically fastened (screws + plates in overlap)<\/li>\n<li>Fully adhered (contact adhesive or PU glue)<\/li>\n<li>Loose-laid + ballasted (gravel or pavers) Seams are always hot-air welded.<\/li>\n<\/ul>\n<p dir=\"auto\"><strong>5. Is hot-air welding required, or can I use glue for seams?<\/strong> Seams must be hot-air welded (180\u2013220 \u00b0C) for water-tightness. Glue or tape is only for temporary fixing or small repairs.<\/p>\n<p dir=\"auto\"><strong>6. What thickness should I choose?<\/strong> 1.2 mm \u2013 light-duty roofs, internal use 1.5 mm \u2013 standard single-ply roof 1.8\u20132.0 mm \u2013 high-traffic roofs, tunnels, bridges, underground<\/p>\n<p dir=\"auto\"><strong>7. Does the membrane contain plasticizers that migrate over time?<\/strong> Yes. Modern formulations minimize migration, but long-term flexibility loss can occur after 15\u201320 years in exposed conditions. Use TPO if zero-migration is critical.<\/p>\n<p dir=\"auto\"><strong>8. What colors are available?<\/strong> Standard: light grey, white (high reflectivity). Custom colors on MOQ.<\/p>\n<p dir=\"auto\"><strong>9. Can PVC membrane be walked on after installation?<\/strong> Yes, once seams are welded and inspected. Use protection boards under heavy equipment.<\/p>\n<p dir=\"auto\"><strong>10. How do I repair a puncture?<\/strong> Cut a round patch (min. 10 cm beyond damage), clean both surfaces, hot-air weld in place, and probe seam.<\/p>\n<p dir=\"auto\"><strong>11. Is the membrane recyclable?<\/strong> Yes. Factory off-cuts and clean demolition material can be returned to PVC recycling streams.<\/p>\n<p dir=\"auto\"><strong>12. What is the standard roll size?<\/strong> Thickness: 1.2 \/ 1.5 \/ 1.8 \/ 2.0 mm Width: 1.0 m or 2.0 m Length: 25 m Weight: 1.5\u20132.5 kg\/m\u00b2 depending on grade.<\/p>\n<p dir=\"auto\"><strong>13. Do you supply fleece-backed rolls for direct adhesion to concrete?<\/strong> Yes. Fleece-backed (FB) versions are available for PU or epoxy bonding systems.<\/p>\n<p dir=\"auto\"><strong>14. What warranty do you offer?<\/strong> Material warranty: 10\u201315 years (thickness-dependent). System warranty up to 20 years with certified installers.<\/p>\n<p dir=\"auto\"><strong>15. Where can I see test reports?<\/strong> EN 13956 (CE), ASTM D4434, GB 12952-2011 reports are available on request.<\/p>\n<p dir=\"auto\">Contact Great Ocean Waterproof for project-specific advice or samples.<\/p>\n<p dir=\"auto\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-988 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/PVC-Membrane-Waterproofing-2_1.webp\" alt=\"PVC Membrane Waterproofing\" width=\"1141\" height=\"840\" srcset=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/PVC-Membrane-Waterproofing-2_1.webp 1141w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/PVC-Membrane-Waterproofing-2_1-980x721.webp 980w, https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/PVC-Membrane-Waterproofing-2_1-480x353.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1141px, 100vw\" \/><\/p>\n<h2 dir=\"auto\">About Our Factory<\/h2>\n<p dir=\"auto\">Great Ocean Waterproof Technology Co., Ltd.
