INTRODUCTION The dictionary definition for waterproof basement construction is “a basement construction impervious to water ingress.” This can only be achieved when all three components of basement construction (basement wall, basement wall to footing/slab junction, and footing/slab) are impervious to water. The water ingress into the basement may be prevented by applying membranes covering all three components. This is called a fully tanked basement solution. A fully tanked basement solution is: Expensive and time consuming to install. May result in the loss of extensive commercial space behind the wall. Is not 100% reliable. In the event of failure, point of failure is all but impossible to determine. Australia does not have a basement construction code. Many Australian professionals follow BS8102 – British Basement Construction Code as a guidance. The Australian requirement is to minimise ground water intake and reduce energy demand and maintenance of drainage pump-out systems as stated in the following NSW Government-document. https://www.industry.nsw.gov.au/__data/assets/pdf_file/0004/343291/minimum- requirements.pdf A basement is a space for carparking or commercial use located below the natural ground and usually below public street level which is accessed with a driveway ramp. The rainwater from driveway ramps has to be collected and discharged to the public sewer/stormwater outlet with a pump-out system. Considering it is not possible to eliminate the use of a pump-out system for the majority of cases, the most logical solution is to minimise ground water intake around the basement walls and collect the water with dish drains. These dish drains, which are connected to the pump-out system, can also be used for the collection of water for general cleaning purposes and possible burst basement sprinkler systems. For the reasons explained later, the installation of a fully tanked basement is risky and not a viable solution ether financially or practically . It is therefore most logical to limit the ground water intake to AS3735-2001 (standard for testing Concrete Structures Retaining Liquids) complaint seepage rate which is significantly better than the seepage rate solution presented in BS8102 for Basement Car Parking areas. Australian guidance also recommends the use of cavity drains (i.e., ventilated double wall and cavity drain in between) if the basement is to be used for habitable space purposes.
