BPI Membrane Fibre/Fleece Overtape – 100mm x 10m

Product Description

BPI Membrane Fibre/Fleece Overtape (100mm x 10m) is designed for professional cavity drain membrane installations, providing a reinforced surface over joints and fixing points to facilitate plastering, rendering or drylining finishes.

Manufactured with a high-strength fibre fleece, this overtape bridges membrane joints and covers fixing plugs, creating a stable, keyed surface for subsequent finishes. It helps distribute load across the membrane surface, reducing the risk of cracking or weak points in the final finish.

Used as part of a complete Type C waterproofing system, this overtape ensures a consistent, professional finish while maintaining the integrity of the underlying membrane installation.

Special Features

• Fibre/Fleece Reinforced – Provides a strong, stable surface for finishes
• 100mm Width – Ideal for covering joints, seams and fixing points
• Improves Finish Adhesion – Creates a keyed surface for plaster, render or adhesives
• Crack Reduction – Helps distribute stress across joints and fixings
• Flexible & Easy to Apply – Conforms to membrane profiles and surface irregularities
• Trade-Grade Quality – Designed for professional waterproofing systems
• Trade Tip: Apply over all joints and fixing points prior to finishing to ensure a uniform surface and reduce the risk of cracking—particularly important when using dot & dab or direct plaster finishes over membrane systems.

Typical Applications

• Covering cavity drain membrane joints and overlaps
• Reinforcing over membrane fixing plugs prior to finishing
• Preparing surfaces for plastering, rendering or drylining
• Internal basement waterproofing systems (Type C)
