The Cementaid Group was founded by Peter Aldred, DFC, in 1954. After serving in the RAF during World War 2, Peter started his concrete admixtures business in 1946. After 4 years of research and development, Everdure Caltite was launched in 1958 and to this day the proven formulation has remained unchanged. The effectiveness of Everdure Caltitecan be seen from the photos below where ordinary absorbent concrete has allowed massive salt scaling and sulfate attack to occur as aggressive ground-water borne chlorides and sulfates are absorbed into the structures. The proven waterproofing and corrosion-resisting capabilities of Everdure Caltite are amply demonstrated here in these comparative photographs. In an otherwise similar concrete, the one modified with Caltite has protected both the concrete matrix and the reinforcement.
