Stitchbond Membrane

Description

Stitchbond Membrane is a non-woven polyester fabric commonly used as a reinforcing membrane in waterproofing systems, particularly with bituminous coatings, acrylic waterproofing compounds, or liquid-applied membranes.

🧵 What Is Stitchbond Membrane?

• Made from: 100% polyester fibers that are mechanically bonded using a “stitch bonding” process (not chemically glued).

• Appearance: Soft, white fabric—lightweight yet strong.

• Purpose: Acts as a reinforcing layer that improves flexibility, crack-bridging ability, and overall strength of waterproofing systems.

✅ Key Features:

• High tensile strength and durability.

• Excellent elongation and flexibility.

• Chemically inert – compatible with most waterproofing products.

• Rot-proof and resistant to biological attack.

• Easy to handle and cut on-site.

🔧 Common Applications:

1. Roof waterproofing: Used with bitumen, rubberised or acrylic waterproofing products.

2. Flashing and joints: Reinforcement in high-movement areas like corners, pipes, and wall/roof junctions.

3. Wet areas: Bathrooms, balconies, and other moisture-prone zones.

4. Dams, canals, and ponds (when combined with liquid waterproofers).

🛠️ How It’s Used:

1. Apply a coat of waterproofing compound.

2. Embed the stitchbond membrane while the compound is still wet.

3. Apply a second coat to fully saturate the membrane and seal it in.

📐 Sizes:

• Commonly available in 100mm, 150mm, 300mm, and 1m widths.

• Roll lengths: typically 10m – 50m, depending on brand.
