Kemper System’s Kemperol cold liquid applied waterproofing membranes have played a vital role in protecting the iconic towers of the Grade I listed Clifton Suspension Bridge in Bristol as part of a refurbishment project.
Specialist contractor, Rateavon Ltd, was appointed to waterproof the towers’ platforms and refurbish the gutters for each tower, selecting Kemperol 2K-PUR and V210 to carry out the work. Rateavon began by removing the existing bitumen coating from the towers’ cast iron gutters, using Kemper System’s solvent-free Kemperol 2K-PUR to replace it. There are limited falls to the gutters and are prone to standing water so the Kemperol system was chosen for its durability in these conditions and the longevity it offers with a BBA-accredited 25 year service life.
The contractor also selected Kemperol 2K-PUR for its compatibility with the zinc primer used to prepare the cast iron substrate and ease of application to the vertical surfaces. Tom Smidek from Rateavon said "This project combined the challenges of a listed structure, an exposed installation and working at height; and Kemper System was able to provide a solution to meet all these requirements. “The new Kemperol surfaces will provide a long-term waterproofing solution with no risk of uplift and a visual appearance that matches the structures’ original design.”
