Solvent-Free liquid waterproofing for Airport

Solvent-Free liquid waterproofing for Airport

Kemper Systems' Kemperol 2K-PUR liquid waterproofing system has been installed at Liverpool John Lennon Airport. Wear and tear demanded the installation of a new roof for the control tower without any disruption to its 24/7 operation.

This demanding environment meant that the roof refurbishment had to be carried out without any disturbance to air traffic controllers, who must be able to concentrate fully at all times. As a result, roofing contractor, W Swindells & Son Roofing selected Kemper System’s odourless Kemperol 2K-PUR cold applied liquid membrane for the project. The control tower’s existing roof surface was bitumen which had not been replaced since the building was first constructed. The refurbishment saw W Swindells & Son overlay the existing substrate with the Kemperol 2K-PUR liquid membrane in a single wet-on-wet process.

The Kemperol 2K-PUR resin was applied section-by-section to the roof using rollers. The flexible reinforcement fleece was cut to size and shape on site and laid onto the wet resin. The installation team then immediately applied more resin to fully saturate the fleece removing any air bubbles or creases with the rollers. The resin then cured to form a seamless, durable and U/V stable monolithic membrane.

John Swindells from W Swindells & Son said "The a cold-applied liquid system was ideally suited to meet these challenges: the use of hot works would not only have created noise and odours but would have involved carrying cumbersome equipment and gas bottles through the control room. Instead, we just needed to take manageable sized sealed containers of Kemperol 2K-PUR through the control room to the roof, along with the reinforcement fleece and rollers.”
