Bosch Alternator Manufacturing Plant, Cardiff

Client: Bosch
Contractor: SPV Roofing & Cladding
Type of works: supply of 30,000m² of Rhepanol fk roof membranes.

Speed and planning were the co-drivers of success when Bosch chose Rhepanol fk to re-roof the manufacturing plant at the heart of its world-wide alternator production.

A tight 12-week schedule and zero-level disruption were paramount at the plant, where the 1,000-strong workforce continued production round the clock throughout installation.

PIB-based Rhepanol fk, one of the world’s most advanced roofing membranes, with a synthetic fleece backing and integrated self-sealing edge, was chosen to provide a watertight solution for the 30,000 m² roof.

The original roof was made up of Durox lightweight concrete with a layer of felt, fibreboard insulation and a felt waterproofing system. Rhepanol fk was laid over the existing concrete decking and mechanically fixed using Gripfix, a unique hook-and-loop fixing strip.

The work was completed within the strict 12-week time frame with no disruption to the demanding 24-hour production schedule, despite some unfriendly weather conditions.
