Derbigum Flat Roofing Solution for Hampton Court and Richmond Court
Posted by david.luukas
Alumasc’s Derbigum Flat Roofing System has been used at Hampton Court and Richmond Court – two historic five-storey apartment blocks, which have undergone a £2.9m refurbishment for Birmingham City Council as part of the Constructing West Midlands framework.
Derbigum was the preferred system for the project as it had been used successfully by the client’s architect Acivico in previous installations and offers a unique 25 year single-point warranty covering both the waterproofing system and associated Alumasc products.
A prerequisite of the works was that the old roof be entirely stripped back for structural assessment to ascertain whether any damage or issues had arisen as a result of the local area being bombed during World War 2. Initial test areas were exposed to establish the condition of the structure, with intrusive samples being taken to evaluate the depth and reinforcement contained within the roof slab.
A total of 800m2 of Derbigum Mineral in charcoal was installed to the roofs of both buildings by Alumasc’s Registered Contractor Brindley Asphalt Ltd. This included the use of a vapour control layer and full polyurethane insulation scheme, also supplied by Alumasc.
To minimise the appearance to the external façade, the Derbigum roofing system was dressed to encapsulate the perimeter parapet and Alumasc’s Skyline polyester powder coated aluminium coping system was installed.
Speaking about the installation, Charlie Pursehouse, Director at Brindley Asphalt, said:
“An integral part of the new waterproofing system was the client’s requirement to increase the falls present on the main and lift motor room roofs, which resulted in the design and specification of a fully tapered Derbifoam insulation scheme. This has further benefitted residents due to the resulting increase in ‘U’ values.”
