Brooklands Racetrack
Brooklands is a disused motor racing circuit and airfield just 20 miles south west of London near Weybridge. Today it houses the Brooklands Museum and Mercedes World, with many of the old buildings and track reinstated to their former glory.
Gifford and Partners produced the ‘Specification for Works in Relation to Scheduled Monuments’, which included a performance specification for the concrete based on the original construction.
As the aggregate used in 1937 was not available from the original source a similar alternative flint material was found in a quarry in Norfolk. Our concrete technician was then able to design the mix to match that of 1937.
Defective concrete was removed by electric hand breakers and edges square cut prior to the installation of a DPC, spacers and mesh. Due to the small quantities required each day and limitations imposed on the access to the track, site batching was considered the most economical option. Once cast, the repairs were cured with polythene sheeting in accordance with the specification.
