Wet Areas & Overflow Protection – A Guide For Specifiers

Within wet areas – in bathrooms, laundries and kitchens – there exists an ongoing risk of overflows and excess water accumulation.

Needless to say, the negative consequences of such events – which range from musty, damp, and unhealthy conditions to corrosion and building damage – are worth avoiding.

In Australia, regulatory requirements are in place to ensure this is the case. The National Construction Code (NCC) includes provisions that apply specifically to wet areas and overflow protection. Specifically, Part F2 of NCC 2022 Volume One, which applies to Class 2 to 9 buildings (which include multi-residential, commercial, and public buildings) is the section specifiers need to consider.

This session of CPD Live focusses on these regulations. Our speakers outline the roles that floor wastes and overflow drains play in this context, identify the types of products available, highlight design and compliance strategies for architects, and cover all other relevant considerations for specifiers to consider when dealing with wet areas and overflow protection.
