Cementaid was begun in 1946, by Mr. Peter N. Aldred, in Perth, Western Australia. The first Cementaid company was registered in 1954, and the company, while remaining privately owned, has grown to be a small mulitnational. Cementaid products have now been installed in 38 countries around the world. Cementaid invented and proved the concept of permanently, inherently DRY structural concrete, using the Everdure Caltite System of hydrophobic pore-blocking ingredients, thereby eliminating any need for conventional membrane 'waterproofing' of structures, and delivering design life durability without maintenance.
