Australia has many tens of thousands of kilometres of buried cast iron cement lined (CICL) piping commonly used for both water and sewage. For utility providers, to manage these assets effectively and keep them in service, it is important to quantitatively understand their condition. Grey flake graphite CICL loses wall strength by a corrosion process called “graphitisation”. ALS has developed a technique using magnetic induction that is able to measure the depth of graphitisation.
ALS have a specialised concrete diagnostics team, within our larger integrity group, who take a holistic engineering led approach to concrete.
