Basement Waterproofing Design

When it comes to the requirements for basement waterproofing, there are a number of considerations that can influence the waterproofing system that is applied. Each site and project can be different and should take a bespoke approach to basement design based on the site conditions and intended use.

Why do I need to Waterproof my Basement?

The answer to this question can be wide and varied, such as the project locations that look to have basements as part of their structure. The National Construction Code (NCC) prescribes that certain levels of amenity need to be maintained for habitable spaces but Councils and Water Authorities can also prescribe the need for basements to capture and either retain or dispose of water effectively. The reasons for 'tanking' a basement can include groundwater, flood zones, capacity of stormwater in the area, contaminants in the soil, the type of soil and adjacent land or properties.

What is required under the National Construction Code for Basement Waterproofing?

The National Construction Code is a collation of Australian Standards and adopted practices for guidance on construction works in Australia. However, when it comes to waterproofing of below ground structures, there is not currently an Australian Standard for reference on how this should be addressed.
