Victoria Wharf, Wales

Client: Victoria Wharf
Architect: Holder Mathias Architects
Contractor: W A Roofing Ltd
Type of works: supply of Hydrotech MM6125 structural waterproofing and the Blackdown green roof system.

High-performance waterproofing solutions from Alumasc have been chosen for a major new residential complex overlooking Cardiff Bay in Wales.

Victoria Wharf is a prestigious development of high-quality riverside apartments and townhouses, featuring attractively landscaped courtyards between the apartment blocks. Project architects, Holder Mathias Architects, and developers, Taylor Woodrow, were both keen to specify Alumasc products, based on their proven track record and suitability for purpose.

Alumasc’s approved contractor, W A Roofing Ltd of Bristol, installed a total of 1,200m2 of Hydrotech MM6125 structural waterproofing and Blackdown green roof systems to the courtyard areas, which were constructed on podium roof structures above a two-storey car park. The Blackdown system was also used in the courtyard planters to maintain consistency in supporting the roof’s excellent drainage properties.

Hydrotech is the first choice for zero falls waterproofing on inverted green roofs and hard landscaped podium structures in new build applications. It comprises a high-performance bituminous rubber blend that allows fast and simple installation, even over complex roof details. This benefit paid dividends at Victoria Wharf as it enabled the waterproofing and detailing to be sequenced with other work on site, ensuring the construction programme ran to schedule.

Blackdown green roofs from Alumasc offer notable ecological benefits, providing a natural habitat for plants and wildlife, while helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation. They vary from extensive and biodiverse types which require minimal irrigation and maintenance, to intensive roofs, which are suited for areas of public and recreational use and require more tending.
