In early May Structural Renovations were employed to carry out emergency repairs to the reinforced concrete at Carnival Pool in Wokingham.
The leisure complex was constructed in the early 1990’s and following a detailed survey of the undercroft areas of both the main and learner pools it was established that extensive repairs would be required to the supporting beams, soffits, drainage channels and external walls of the pools.
The complex is planned for redevelopment in 2020 but in order to keep it operational until then a repair scheme had to be implemented that would provide the required protection in an aggressive environment.
Working closely with the local authorities consulting engineer it was agreed that defective concrete would be removed and any exposed reinforcement treated prior to reinstatement with a polymer modified repair mortar. In certain locations where the warm, moist atmosphere, combined with chemical attack was most likely to accelerate the deterioration of the concrete a migrating corrosion inhibitor (MCI) was applied.
Additional works instructed included waterproofing the drainage channels, both internally and externally, using a thixotropic modified polymer coating, complete with an embedded elastomeric composite tape.
This 6 week project was completed on time and due to careful programming the public parts of the complex were required to be closed for only 2 of those weeks.
