Located at the University’s Bloomsbury site in the heart of London, the campus is one of the university’s busiest. Taking its name from the eminent British chemist, the building is home to the chemistry department and remained fully occupied and operational throughout the refurbishment.

To ensure that disruption to staff, students and members of the public was kept to a minimum, Delomac worked closely with main contractor Russell Cawberry and the UCL Estates Department to manage the project appropriately.

At the client’s request, Delcomac installed a Sika Sarnafil S327-15EL membrane in Light Grey, favoured for its long life span, environmental credentials, lack of hot works and its adaptability to being able to be fit on an existing overlay, meaning the existing roof didn’t have to be stripped beforehand.

A number of challenges arose during installation, including the dismantling of the cleaning cradle system and tight restricted access and limited working heights under and around plant detailing. Working under Sarnafil consultation, the latter problem was resolved by prefabricating blankets on site to pull under the plant, making areas more accessible to affect the final weld.

The project was successfully completed to the client’s satisfaction, on time and budget.

"We’re really happy with the overall aesthetics of the project. What was once a messy area has turned into a properly water tight, detailed and sound structured roof. That we’ve got a further five phases of work with UCL in the pipeline show that it’s clear they’re as pleased with the final result too." Brendan McNulty, Director at Delomac
