Kemper System prescribed for multi-million- pound hospital building
K
emper System’s cold-applied liquid waterproofing
solution has is roller-applied, been specified for a multi-million-pound
extension at St John’s and St Elizabeth (HJE) Hospital in London. The £35m new build development has created six, hi-tech theatres and a day case suite which is one of the most modern in the UK. A total of 9,060 sqm of Kemper System’s Kemperol 2K-PUR solvent-free and odourless waterproofing membrane has been applied beneath the building’s green roof, onto a pedestrian trafficked walkway, the lower roof area and a plant roof area. The cold-applied solution was installed by London-based Ridgewell Flat Roofing Ltd. Because of the location of the new build extension, adjacent to an occupied hospital building at HJE,
the solvent-free and
odourless qualities of the Kemperol system meant minimum disruption at the hospital throughout the application process. No hot works were required as part of the project,

Ridgewell Flat Roofing, said: “We have used Kemper System for many years, and the cold-applied solution was perfect for this prestigious project because it is so versatile. We could apply the system to each of the different roof and walkway areas with ease without having to switch roofing materials. Kemper System once again delivered on such a complex project, which presented winter working challenges, specifically with high winds at times. Large expanses of sheeting material would have not have been practical or safe on site, so a roller-applied liquid waterproofing solution was the best for this project. We were extremely happy with the results, and so is the end client.”
