In the early seventies the well established use of polysulphide sealants in water-retaining structures was brought into question by the biological deterioration of a sealant in the Dunkeld Reservoir In Johannesburg. As a result, comprehensive studies were undertaken in South Africa and the UK on the mechanism of the degradation and the factors that influenced it.
