The impressive Belvedere Court 4-storey building, which was converted from a hotel into 16 prestigious residential apartments in 2008, recently underwent further development including extensions for additional accommodation, basement housing, a communal swimming pool, a theatre and an underground car park.

As part of the refurbishment of the site, the failing waterproofing of the green roof on the car park roof deck needed to be removed and replaced. Bauder approved contractor, The Complete Roofing Company (TCRC), initially proceeded to remove the existing pathways and landscaping before removing the failed system and providing remedial repairs to the damaged roof.

The specification

With the car park roof also being used as a recreational green roof for the residents of Belvedere Court, the Bauder Hot Melt Intensive Green Roof System was an obvious choice. The Bauder Hot Melt Bakor 790-11 EV with Polyester reinforcement creates a resistant monolithic waterproofing membrane whilst the Bauder AP2 root barrier provides resistance to the system allowing for a green roof to be installed above. As stated by BBA certificate 06/4350, this system provides a durable waterproofing solution for the service life of the structure in which it is incorporated.

The result

On completion of the waterproofing elements, the roof was leak-tested to ensure the roof’s integrity. The TCRC then installed the Bauder green roof components; PE foil, FSM600 protection membrane, DSE40 drainage layer, filter fleece and over 300 tonnes of Bauder intensive substrate. Finally, Rowland Gold turf was then installed with a drip line irrigation system installed under the turf. Upon final assessment, this project met the criteria to be issued a 20-year product and workmanship guarantee.
