Delta Corner Strip is a robust waterproof and vapour-proof sealing strip, made from premium-grade butyl adhesive and an ultra heavy-duty backing layer. It is designed to provide a durable, watertight seal at critical junctions and detailing points within Delta cavity drainage membrane systems.
Essential for use in Type C waterproofing, Delta Corner Strip ensures continuity between membrane components and around service penetrations—especially in basement and below-ground waterproofing applications.
