Situated deep in the heart of the city, one of London’s most prestigious urban village developments provides a welcome slice of countryside. The New Providence Wharf and Ontario Tower apartments/hotel complex at Blackwell Way, Docklands, has created an oasis of natural biodiversity, thanks to Alumasc, specialists in sustainable roofing solutions.
The Solution:

Developers Ballymore incorporated Alumasc ZinCo green roof systems within the project, which was supported by local authority Tower Hamlets, who encourage ecologically sound building practices. The different roofs were formed using Alumasc’s Hydrotech and Derbigum waterproofing systems and a combination of bio-diverse and intensive green roof build ups.

The ZinCo green roof system used on the tiered roofs of New Providence Wharf and adjoining Ontario Tower, replicates a naturally occurring ground soil structure, but incorporates highly efficient thermal insulation, drainage and a variety of planting options.

Hydrotech structural waterproofing was the perfect solution for the New Providence Wharf podium, roof and balcony areas, due to its ability to interface with diverse detailing elements such as the glass fibre-lined canal, curtain wall and drainage outlets. Hydrotech achieves 100% absolute bond to a range of substrates, with no risk of water tracking below the membrane or of lap failure. It features a unique reinforced formulation, which results in a tough, yet flexible, self-healing membrane designed to last the lifetime of the building.

The award-winning Derbigum waterproofing membrane was specified to complete a section at ground level within the development where an epoxy bonded gravel paving was to be installed over the waterproofing, requiring a more rigid base to support the decorative paving surface finish.

The project architects were Skidmore Owings & Merrill and the Roofing Installer was Briggs Amasco.

The Benefits
The green roofs on the project benefit both residents and wildlife, improving air quality and providing a technically advanced, visually pleasing and effective roofing system.
