This determination arises from the decision of the authority to refuse to grant an amendment to a building consent for remedial work. The need to amend the building consent arose when water ingress was found in a deck area of a house while remediation work to the house was being undertaken. A solution was designed that incorporated a floating in-situ concrete topping slab over a waterproofing membrane (the amended work). The authority was not satisfied that the amended work will comply with the Building Code and in particular is concerned about the inability to maintain the membrane. The matter to be determined is therefore whether the amended work, which is now largely completed, will comply with Clauses E2 External Moisture and B2 Durability of the Building Code. The amended work is part of a larger body of alterations and remediation work being carried out on the house. This determination considers only the amended work as described above.
