I have a garden wall the concrete of which keeps developing salt-like crystals and crumbling away. Brushing away the loose material and replacing with fresh concrete does not seem to work. I think the wall itself was built in the sixties-is this likely to be concrete cancer and is there a cure for the problem. The soil behibd it is pretty rubbish so I was going to infill to a depth of a couple of feet with better soil-but not if the wall is likely to collapse!
