The Harris Federation, Aspire Academy in Beckenham is to be relocated to the former South Norwood police station site in Oliver Grove and the expanded school will include a sixth-form college and cater for a maximum of 365 students. A complete overhaul and refurbishment of the current police station was needed to provide a safe, cheerful and welcoming environment to students. Fosroc were invited by Galliford Try to provide a solution for upgrading the basement car park structure, which already provided primary protection to a Grade 2 standard, to a Grade 3 habitable space.
Fosroc provided a complete concrete repair and waterproofing solution. After protecting all exposed and prepared steel with Nitoprime Zincrich Plus, structural reinstatement of degraded concrete was carried out using the Renderoc repair system with added protection provided by Protectosil CIT corrosion inhibitor, applied to all areas of reinforced concrete at risk from corrosion. Prior to the installation of the Grade 3 Cavity Drainage System, all construction joints were overcoated with Nitocote CM210 as additional waterproofing protection. The BBA approved Proofex Cavitydrain System was then installed including channels connected in turn to sump and pump units to ensure any ingress will be extracted from the basement.
Fosroc was able to provide bespoke detail drawings for this project and worked closely on the layout of the drainage system with the contactor Advanced Preservations Ltd – a member of the Fosroc Waterproofing Alliance, trained and experienced in applying Fosroc products. The application of Protectosil CIT provides protection to the structure, reducing future maintenance costs. With a comprehensive range of products Fosroc was able to provide a ‘One-stop-shop’ for both concrete repairs and waterproofing.
