Cheers King. The concrete barge is badly leaking onto the roof timbers under, so it can be proven. Also, i have just recently recieved phots of the barge been poured, and there wasnt any sign of water proofing, and to make matters worse, no cavity closer, which means concrete would have poured into the cavity. Other pictures show the wall plate abuting the inside of the outer leaf, projecting through the inner leaf. Ditto for the battens for the slates.
