Denso™ System Repairs Damaged

A bitumen tape wrap system from Winn & Coales (Denso™ System Repairs) Ltd was utilised for the repair of damaged pipework at the new HS2 terminus at London Euston train station.

Following damage to the existing factory coating, corrosion had already begun to inflict damage upon the pipe and had propagated underneath the coating itself, causing it to delaminate. To eliminate further damage, The Denso™ System Repairs Bitumen Tape Wrap was applied to not only protect the pipe from the effects of further corrosion, but to provide a large degree of mechanical protection too.

Densoclad 70™ Tape is applied over the bitumen-based primer (inset) before the whole system is encapsulated with Denso™ Glass Outerwrap.

Winn & Coales (Denso) Ltd are leading manufacturers and suppliers of corrosion prevention and sealing systems. The bitumen tape wrap system supplied for the project was comprised of a bitumen-based primer (Denso Primer D^™), a heavy-duty PVC-backed bitumen tape (Densoclad 70^™ Tape), and a protective outerwrap (Denso™System Repairs Glass Outerwrap). The protective outerwrap offers exceptional mechanical and impact strength for buried pipes exposed to aggressive backfill conditions. Once applied and fully cured, the whole system provides a long-term protective coating that is ready for immediate service.
