RCM Waterproofing Membrane

The RCM Waterproofing Membrane is a high-strength, non-woven 100% polyester stitch-bond fabric engineered to work hand-in-hand with liquid-applied waterproofing coatings. It reinforces the waterproofing barrier over joints, cracks and difficult surfaces, adding strength, flexibility and long-term durability to roofs, flashings and other high-stress areas.

Key Features

• Non-woven polyester stitch-bond fabric for strength and flexibility
• Coating reinforcement for extra durability and crack resistance
• Improved adhesion helping coatings bridge gaps and uneven surfaces
• Dimensional stability while remaining flexible with the surface
• Easy to cut and shape to any surface or architectural detail
• Tear and fray resistant for smooth application and clean finishes
• Multiple widths and lengths to suit both detailing and field work

Specifications

• Sizes available: 100mm, 200mm, 500mm and 1000mm widths in 10m and 20m lengths
• Material: Non-woven 100% polyester stitch-bond fabric
• SKU: 8746833641624-eco-rubber-waterproofing-membrane

Typical Uses & Applications

• Roofing and flat decks reinforced across the field with the wider rolls
• Parapets and flashings banded along high-stress edges
• Joint and crack sealing using the narrower detailing widths
• Corners and penetrations shaped with cut-to-fit pieces
• Gutters and valleys lined to hold movement over time
• Residential and industrial waterproofing across a range of surfaces

Usage Tip

Choose the width to match the job, a narrow strip for detailing and a wide roll for the open field, then embed the membrane into the wet RCM coating with full saturation for the best adhesion and performance.

A versatile reinforcement layer that helps any liquid-applied waterproofing system last longer.
