BluSeal VLDPE Trumpet
Preformed VLDPE Conical Shaped Flanged Trumpet
Product Overview
BluSeal VLDPE Trumpet is a preformed, flanged penetration detailing component designed to provide a watertight termination for services passing through VLDPE tunnel waterproofing membranes. The conical trumpet profile accommodates a wide range of penetration diameters from 12 mm to 50 mm, allowing flexibility across multiple service types. Used in conjunction with the BluSeal VLDPE Tunnel Liner, the system maintains continuity of the waterproofing membrane while providing a secure seal around pipes, reinforcement, conduits, Z bars, and threaded rods. BluSeal VLDPE Trumpet can also function as an injection or back grouting point, supporting sealing and remediation works behind the membrane where required.
