Swimming pools present a notoriously aggressive environment for building materials including reinforced concrete, so it is a measure of Marmox Multiboard’s inherent durability and other attributes that it has been specified for an unusually challenging refurbishment contract at a leisure centre in Peterborough. Following the specification for the upgrade, half-size sheets of Marmox’s tile backing board ‘Multiboard’, measuring 1250 x 600 mm, were able to be fixed directly over the top of the existing asbestos based substrate, the Multiboards also offer a greatly improved thermal performance which will help prevent problems of condensation forming. The boards had been treated with one coat of EP150 on the reverse side and received a further two coats on the visible face. The refurbishment of the rooflights was successfully completed with three months.
