The question has been raised regarding requirements for venting of the roofs on this building. The following points should be noted: 1) It is not the roof membrane which determines whether vents are required or not, but the construction of the roof, the roof space between the outer skin and the inner lining and the use of those areas immediately beneath the roof, which determine whether venting is required or not. 2) The purpose of venting is to ensure that there is no build-up of deleterious moisture within the space below the roof skin.

VIC – DELWP have rejected draft regulations for mandatory inspections of waterproofing


In a surprise reversal of the Victorian Building Regulations 2017 Draft the reforms to help correct the chronic waterproofing failures in buildings have been scrapped. The rationale for the reversal was feedback from the Building Surveyors fearing legal liability. Thus we go back to the beginning with the Builder (being the head Building Practitioner) required to sign off on Compliance of the waterproofing, with cover under his insurance.

Educating Specifiers


All too often we find the waterproofing details on project specifications are non-existent or very lacking in proper details. We find the waterproofing lumped in with all sorts of other items such as tiling, painting, plumbing, structural engineering and such. If the details are ambiguous then the old "apples for apples" is extremely difficult to apply and prices are all over the place. Most waterproofers have their own particular like and dislikes when it comes to what materials to use and how to install them. Choose the "right" product A particular material may or may not be the ideal product [...]
