Company Profile



The Cementaid Group was founded by Peter Aldred, DFC, in 1954. Peter was born in Luton, England and served in the RAF during World War 2.

Shortly after returning to civilian life, Peter’s interest and research into advanced concrete technology led him to being recognised as one of the Industry’s pioneering developers of admixtures and additives for enhanced concrete performance. 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 Caltite can 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. Originally built in 1962, the Caltite protected support chairs remain in excellent condition today.

Peter is pictured above (Right) receiving the British Board of Agrément certificate for Everdure Caltite from Peter Hewlett in 1993.
