Northcroft Lido - Olton Structural Consulting, Bury St. Edmunds

Project Details

We were engaged by KRP Consulting Engineers to design and specify concrete repairs and waterproofing to an existing reinforced concrete pool shell, into which a new 50m Olympic Length outdoor swimming pool was to be constructed. The original pool shell comprised a Victorian tank of reinforced concrete construction tanked internally with asphalt. This original tank was subsequently lined in the 1960’s with a reinforced concrete liner. The structure had deteriorated due to long term leakage both into and out of the pool, through service penetrations, cracks and movement joints.

The remedial design included a new reinforced concrete retaining wall, which was installed to define the reduced length of the new pool as well as a suite of concrete patch repairs, remedial works to existing movement joints and a cementitious flexible waterproof slurry coat.

The pool base was piled, movement joints locked up and sealed, a new ground slab constructed and the existing walls increased in height.
