JY-GBL Polymer Waterproof Membrane PE PP Polyethylene Polypropylene Waterproofing Membrane

Pasiuna sa Produkto

The JY-GBL Polymer Waterproof Membrane is a composite material consisting of polyethylene and polypropylene layers, developed as an extension of traditional waterproofing and anti-seepage products. 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.

This 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.

Common 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.

Mga Kinaiya sa Produkto

• Physical Properties: Exhibits anti-aging, anti-oxidation, and corrosion resistance. Offers flexibility for bending without breaking, along with tensile strength and resistance to perforation.
• Base Surface Compatibility: Requires minimal preparation; installation can proceed on damp surfaces without standing water. After rainfall, excess water can be removed to allow immediate construction, supporting faster project timelines.
• Puncture Resistance: Designed for use on green planting surfaces, providing resistance to punctures and the ability to prevent root penetration, which contributes to effective waterproofing.
• Composite Structure: Integrates with polymer cement bonding materials for use alongside coil materials, forming a system that supports environmental considerations.
• Environmental Attributes: Non-toxic, odorless, and free from pollution.

Additional properties based on similar polyethylene polypropylene membranes include UV stability for outdoor exposure, a multi-layer design with a waterproof core and protective layers, and a lifespan exceeding 50 years under typical conditions. These membranes maintain integrity across a temperature range, resisting cracking at low temperatures (down to -40°C) and deformation at high temperatures (up to +100°C), while providing strong adhesion to substrates.

Installation Guide

This guide outlines the standard installation process based on the product's characteristics and common practices for similar polyethylene polypropylene composite membranes. 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.

• Surface Preparation: 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.
• Primer or Adhesive Application: 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.
• Special Area Treatment: In vulnerable waterproofing zones like pipe penetrations, expansion joints, internal/external corners on grounds and walls, apply an additional layer of polyurethane coating 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.
• Membrane Laying: 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.
• Joint and Overlap Handling: 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.
• Finishing and Inspection: 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.
• Post-Installation Notes: 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.

Comparison: JY-GBL Polymer Waterproof Membrane (Polyethylene Polypropylene) vs. TPO Membranes

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. While both serve waterproofing needs in construction, they differ in composition, performance, and typical uses. Below is a side-by-side comparison based on standard properties.

In summary, the JY-GBL PE/PP membrane offers broader application versatility and potentially longer service life in varied environments, while TPO excels in cost-effective roofing with reflective properties for cooling. Choice depends on project specifics like exposure to chemicals or installation conditions.

Mga Review sa Kustomer

John R., USA (Contractor, Basement Waterproofing Project)
I 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.

Elena S., Germany (Engineer, Tunnel Lining)
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—no issues with water ingress. It's not the cheapest option, but it performs as expected in industrial settings.

Michael T., Australia (Homeowner, Roof Application)
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.

Aiko H., Japan (Builder, Water Storage Tank)
We 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—had to order extra rolls.

Carlos M., Mexico (Landscaper, Green Roof System)
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. Reliable for planting applications.
