we've just got the results from the survey carried out by the people buying our house and they have told us we have red ash in our concrete floor can anyone shed any light on the subject as neither of usknow what this means
Work your way through this very long thread on the subject in a specialist self-Building website. About half way through is avery good explanation about a correspondent calling himself 'redashman' - this in particular should help you understand what it is and what you might have to do about it.
