Went to view these last week they were done last year by a builder , completely stuffed, customer says they were a quarter to half full of stone at bottom, 4 in total membrane on inside , don’t like getting involved with these tbh as they always seem to be mashed up after a while if you was gonna do them any preference to materials to use or anything else I could advise customer to help not be in a state ...
