Project Details
Winn & Coales (Denso) Ltd was approached by the team at Jacobs to help solve a corrosion issue being experienced on a flood defence site in Greater London. The backing plates to the ground anchors had been suffering from the harmful effects of corrosion and Denso were tasked to provide a solution that would prevent any further damage, whilst still allowing access to the anchors for inspection and general maintenance. The threads of the anchors were already being protected with Denso™ Void Filler Type I (also known as the Steelcoat 50™ System) so Denso were keen to provide a full package of protection.
The Steelcoat™ System provided to Jacobs passed a successful trial by being flexible; surface tolerant; and possessing a long, proven history of success on other projects. The system features a waterproof seal around the outer edge and is UV-stable for when protected areas are exposed to sunlight. Both the contractor and client were very happy with the clean finish and the peace of mind that the backing plates will no longer suffer any more corrosion problems.
The work supported the Environment Agency’s 10-year TEAM2100 programme, a collaboration with Jacobs and Balfour Beatty, to enhance flood defences along the River Thames in London and its Estuary.
The area to be protected is taped and primer is applied (L) before Densyl Mastic is used to fill voids around the anchor cables (R).
Denso's surface tolerant, high tack petrolatum tape is applied (L), then the backing plate is placed into position on the anchor (R).
Denso Primer D is applied to the outer edges of the plate (L). Denso Ultraseal RT Tape is then added before an acrylic topcoat (R).
