Waterproofing – why is it important? And what rules are changing?
Waterproofing—it's the unsung hero of home renovations. While everyone’s ooh-ing and ahh-ing over the latest tiles or that fancy showerhead, it's the waterproofing that's quietly doing the heavy lifting in your bathroom, kitchen, or laundry so that these rooms don't turn into a soggy disaster zone.
Whether you're a seasoned DIYer or just starting your reno journey, understanding the importance of waterproofing and staying on top of the latest rules is crucial. So, grab your gumboots and let's dive into the world of waterproofing!
What is waterproofing?
In the simplest terms, waterproofing is the process of making an area resistant to water penetration. It’s like giving your bathroom, kitchen, or laundry an invisible shield that prevents moisture from seeping into places it shouldn’t. Think of it as the superhero cape your home wears to keep leaks, mould, and other nasties at bay.
What are the benefits of waterproofing in construction?
Waterproofing might not be as glamorous as choosing benchtops, but its benefits are undeniable:
- Waterproofing increases durability
A properly waterproofed space will stand the test of time. By preventing water from seeping into the building materials, you’re protecting your home from the kind of wear and tear that can lead to costly repairs. Waterproofing keeps everything in tip-top shape, extending the lifespan of your renovation.
- Waterproofing prevents mould and mildew
Nobody wants a science experiment growing in their bathroom. Waterproofing creates a barrier that stops water from creeping into areas where mould and mildew love to thrive. A dry space is a healthy space, and by keeping moisture out, you're also keeping your home safe from the health risks associated with mould.
- Waterproofing improves structural integrity
Water damage can weaken the very bones of your home. By ensuring water doesn’t penetrate your walls or floors, waterproofing helps maintain the structural integrity of your space. It’s like giving your home a solid foundation to stand on, ensuring everything stays strong and sturdy.
- Waterproofing reduces maintenance costs
With proper waterproofing, you’re not just saving your home from potential damage but also your wallet from constant repairs. By investing in quality waterproofing now, you’ll save on maintenance costs down the track, keeping your reno looking fresh without the extra expenses.
What areas must you waterproof in the bathroom, kitchen and laundry?
It’s not just the shower that needs a good waterproofing job. Here are the key areas in your wet zones that must be waterproofed:
- Bathrooms: The shower and bath areas are non-negotiables, but don’t forget about the floor, the walls up to a certain height, and even the vanity splashback.
- Kitchens: While the kitchen might not be as wet as the bathroom, areas around the sink, the dishwasher, and even under the fridge should be waterproofed to prevent any sneaky leaks from causing havoc.
- Laundry: With washing machines and sinks, your laundry is another area prone to water damage. Waterproof the floor and walls to keep everything in check.
What are the rules when it comes to waterproofing?
Australia takes waterproofing seriously—because when it goes wrong, it goes really wrong.
The Australian Standards for Wet Area Waterproofing , AS 3740, sets out the requirements for ensuring your wet areas are up to scratch. From the thickness of waterproofing membranes to the correct installation techniques, these standards are the rulebook for keeping water where it belongs.
The Australian Building Codes Board (ABCB) writes the standards, and they get updated from time to time. The last update happened in 2022, and the next one has kicked off and is due for implementation in 2025.
What rules are changing in 2025?
As we head towards 2025, there are a few changes on the horizon in the standard that could impact your waterproofing plans. While the exact details are still being finalised, the focus is on improving the durability and effectiveness of waterproofing methods, particularly in high-risk areas like bathrooms.
Within the standard, there’s a section (or ‘schedule’ is what they actually call it) for each state and territory, so the rules can vary slightly to suit local conditions.
Once the new standards are published, be sure to check what’s changed nationally and locally.
Why are the rules changing?
The changes are meant to help reduce the number of building defects resulting from water sneaking into areas it shouldn’t.
Should I use a qualified waterproofer or can I DIY?
This is where the rubber meets the road. Sure, there are a few things you can tackle yourself in a renovation, but when it comes to waterproofing, it’s usually best to call in the pros. A qualified waterproofer has the experience and knowledge to ensure your waterproofing is up to standard and will stand the test of time. Plus, in many cases, having a licensed professional do the job is a legal requirement.
If you’re a DIY enthusiast, stick to the less critical tasks and leave the waterproofing to someone with the right credentials.
