A Denso™ Bitumen Tape Wrap System, comprising a bitumen-based primer (Denso Primer D™), a heavy-duty PVC-backed bitumen tape (Densoclad 70™), and a protective outerwrap (Denso™ Glass Outerwrap) was recently specified for the repair of a damaged epoxy polyurethane factory coating at the new HS2 terminus being constructed at London Euston train station.
Following the damage to the current coating, the harmful effects of the corrosion process had already begun to inflict damage upon the pipe and had propagated underneath the coating itself, causing it to delaminate. To eliminate any further damage, the Denso Bitumen Tape Wrap System was applied to provide not only protection from further corrosion damage, but a large degree of mechanical protection too.
Denso Glass Outerwrap (GOW) is a fiberglass cloth impregnated with a water activated resin that offers exceptional mechanical and impact strength for buried pipes exposed to aggressive backfill conditions. Once fully cured (after compression underneath a double layer of Denso™ Clear Outerwrap) the Denso GOW fully encapsulates the whole system with a long-term protective coating that is ready for immediate service.
