When Did Waterproofing Become Compulsory in Australia?

Waterproofing your home is compulsory in Australia if you want to avoid expensive repairs down the line. But when did this become the case? The answer may surprise you – waterproofing became a building requirement in Australia in the 1970s!

This was due to an increase in awareness of the importance of waterproofing and its ability to protect homes from weather damage. Before this, many homes were not properly waterproofed and as a result, they suffered from leaks and other water damage. This led to costly repairs that could have been avoided if the home had been properly waterproofed from the start.

Nowadays, there are many different types of waterproofing available, so you can choose the best option for your home. There are also strict requirements that all builders must follow to ensure that your home is properly protected against moisture and damp. If you’re planning on building or renovating a home, make sure you factor in waterproofing – it could save you a lot of money and hassle in the long run!

Dealing with Defects in Apartment Buildings with James Moir

The history of waterproofing in Australia is a long and interesting one. It is believed that the first recorded use of waterproofing was in the early 1800s, when it was used to protect ships from the harsh elements. However, it wasn’t until the mid-1900s that waterproofing became widely used in construction.

One of the first major projects to utilise waterproofing was the Sydney Opera House. The building’s design called for a roof that would be completely watertight, and so a team of engineers devised a system of concrete shells, which were then coated with bitumen and asbestos to create a seal. Since then, waterproofing has become an essential part of construction in Australia, particularly in areas where there is high rainfall or where flooding is a risk.

It is now compulsory in many states and territories, and there are strict regulations surrounding its use. So next time you’re standing under an umbrella or walking through a puddle, spare a thought for the humble waterproofing material that’s keeping you dry!

When Did Waterproofing Become Compulsory in Victoria

Waterproofing has been a requirement in Victoria since 1998, when the Building Act 1993 was introduced. The act made it compulsory for all new buildings and extensions to be waterproofed. This means that any building built after 1998 must have a watertight barrier to protect against moisture and damp.

There are two main types of waterproofing: internal and external. Internal waterproofing is usually done during construction, while external waterproofing is applied to the outside of the building.

Australian Standards Waterproofing Wet Areas

Australian Standards for waterproofing wet areas is a set of guidelines that aim to provide a minimum level of protection against water damage in residential and commercial properties. The standards are mandatory in all new construction projects, as well as any renovations or additions that involve wet areas such as bathrooms, laundries and kitchens. Waterproofing is an important part of protecting any property from water damage, but it is especially crucial in wet areas where the potential for leaks and flooding is much higher.

The Australian Standards for waterproofing wet areas cover everything from the materials and methods used for waterproofing, to the requirements for drainage and ventilation. There are two main types of waterproofing systems that can be used in wet areas: sheet membranes and liquid-applied membranes. Sheet membranes are usually made from PVC or HDPE, and are laid over the surface of the substrate before tiling.

Liquid-applied membranes are applied directly to the substrate using a brush or roller, and then left to cure. Which type of waterproofing system you use will depend on the specific requirements of your project, but both systems must meet the minimum performance standards set out in the Australian Standards. All materials used in wet area waterproofing must also be approved by WaterMark – an independent certification scheme administered by Standards Australia.

Whether you’re planning a new build or renovating an existing property, make sure you choose a reputable contractor who can provide evidence of their compliance with the Australian Standards for waterproofing wet areas. This will give you peace of mind that your property is protected against water damage now and into the future.

When is Waterproofing Required

Waterproofing is required when there is a potential for water to leak into or through a structure. This can happen when the ground around a structure is too wet or if the structure itself is exposed to high amounts of water, such as during a flood. Waterproofing can also be necessary if the structure has cracks or other damage that could allow water to enter.

Waterproofing Bathroom Australian Standards

There are a number of Australian Standards that relate to waterproofing bathrooms. These include: AS 3740-1994 Waterproofing of domestic wet areas

AS 4654.1-2007 Waterproofing membranes for external above-ground use – Selection and design AS/NZS 4858:2013 Wet area membranes Waterproofing is an important consideration when constructing or renovating any bathroom, as even a small amount of water can cause serious damage if it leaks through into the structure of the building.

The purpose of waterproofing is to prevent water from penetrating the fabric of the building, and to protect against both internal and external moisture sources. There are many different types of waterproofing products available on the market, and it is important to choose one that is suitable for the particular application. For example, some materials are designed specifically for use in shower recesses, while others are more suited to balcony decks or other external areas.

It is also important to ensure that the chosen product meets the relevant Australian Standard. When selecting a waterproofing membrane, it is important to consider its resistance to both positive and negative hydrostatic pressure, as well as its ability to withstand ponded water (where water collects on top of the membrane). The chosen product should also be appropriate for the intended substrate (e.g. concrete, brickwork etc.), and compatible with any other materials that will be used in conjunction with it (e.g. render, tiles etc.).

Once you have selected an appropriate waterproofing product, it is important to follow the manufacturer’s instructions carefully in order to achieve optimal results. This includes ensuring that all surfaces are clean and free from dust before application, as well as taking care not to damage the membrane during installation.

What is the Australian Standard for Waterproofing?

There are a number of Australian Standards that relate to waterproofing (which is also sometimes referred to as damp-proofing). These standards cover things like the materials and methods that can be used for waterproofing, as well as specifying requirements for how new buildings should be designed and constructed to minimise the risk of moisture damage. Some of the key Australian Standards relating to waterproofing include:

AS 3740-2010 – Waterproofing membranes for external above-ground use AS/NZS 4858:2004 – Hot spray applied bituminous membranes AS 1562.1-1992 – Design and installation of sheet roof and wall claddings

AS 4654.1-2012 – Waterproofing membranes for external below-ground use When it comes to actually carrying out waterproofing work, there are a few key things that need to be done in order to comply with the relevant Australian Standards. First of all, any existing moisture problems need to be properly diagnosed and addressed.

Once the source of any dampness has been dealt with, then appropriate materials and methods can be chosen for carrying out the actual waterproofing work. This might involve installing a new membrane or barrier, or it could involve injecting a water repellent into masonry walls. Whatever method is used, it’s important that it is installed correctly in order to achieve the desired results.

How Long Has Waterproofing Been Around?

Waterproofing has been around since the early days of human civilization. The first evidence of waterproofing is from the Mesopotamian civilization, where bitumen was used to seal bricks and make them waterproof. Bitumen is a natural substance that is still used today in many waterproofing products.

Over the millennia, people have developed ever more sophisticated methods of waterproofing materials. Today, there are many different types of waterproofing products on the market, each designed for a specific purpose. Waterproofing can be used on everything from clothing to buildings and even electronic devices.

Do You Have to Waterproof a Bathroom?

Bathrooms are one of the most common places in the home that can suffer from water damage. Waterproofing your bathroom can help to prevent this type of damage and keep your bathroom looking its best. There are a few different ways that you can waterproof your bathroom.

One option is to use a waterproof sealant on the walls and floors. This will create a barrier between the water and the surfaces in your bathroom, making it less likely for water to seep in and cause damage. Another option is to install waterproof materials such as tile or vinyl flooring.

These materials are designed to resist water damage and will help to keep your bathroom looking good for years to come. Finally, you can also take some simple steps to waterproof your bathroom yourself. For example, you can apply silicone caulk around doors and windows to help prevent water from entering your bathroom.

You can also install drip pans under sinks and toilets to catch any leaks before they have a chance to do serious damage. Taking some time to waterproof your bathroom now can save you a lot of time and money down the road. Waterproofing will help protect your investment in your home and make sure that your bathroom stays looking its best for years to come.

Do You Need a Waterproofing Certificate in Queensland?

There is no legal requirement in Queensland for a waterproofing certificate, however most building owners will request one from their contractor as proof that the work has been carried out to a satisfactory standard. A waterproofing certificate provides evidence that the contractor has met all of the requirements specified in the contract and can be used as supporting documentation if any issues arise in the future.


In Australia, waterproofing became compulsory in the 1970s. Prior to this, builders were only required to use a damp-proof course (DPC) to prevent moisture from rising up through the foundation and into the building. However, DPCs were not effective at stopping water from seeping through cracks in the walls or floors, which led to serious problems with mold and mildew.

Waterproofing is a much more effective way to keep buildings dry, and it is now required by law in Australia.
