Peter Aldred, DFC, founded the Cementaid Group 57years ago and has been responsible for the development of many products used in the concrete industry including the waterproofing and corrosion inhibiting admixture Everdure Caltite. By protecting the one 'Achilles' heel1 affecting even the highest grades of normal quality concrete, i.e. its intrinsic ability to absorb and transmit water and water-vapour, Everdure Caltite provides reliable structural waterproofing performance, speeding construction programmes and reducing costs. By restricting water absorption to insignificant levels and physically blocking capillary pathways against hydrostatic pressure, the Caltite System is the one, true double-action Hydrophobic & Pore-Blocking Ingredient (HPI) for concrete.
