Background Of The Project

Allard Construction Ltd were appointed by Interserve Ltd/Paragon to carry out the waterproofing works at 30 Cleveland Street in London. The project consisted of both new build and refurbishment works to the 1930’s building.

Description Of Works Carried Out

Allard Construction Ltd installed a 20 year guaranteed waterproofing system. All terrace areas comprised of inverted roof schemes that we refurbished with Langley Paracoat Liquid System. To finish, decking was installed which sat on adjustable pedestals to create a level platform. On the level 6 roof terrace canopy extra works were granted to Allard Construction Ltd where we installed an IKO single ply system.

Challenges Faced

Allard Construction Ltd experienced several design issues regarding the details on the main roof due to the amount of plant that had to be installed in specific locations on the main roof area.


In order to resolve these design issues our team were able to provide alternative designs in line with the Langley specification.
