TPO Deck

This deck on an older house in Karori was previously covered in Butynol rubber membrane and was leaking. The builder dismantled the deck and rebuilt and resloped the framing to take new plywood substrate. We installed Viking Enviroclad TPO membrane (Carlile TPO). A floating timber deck was built over the TPO membrane.
