The part nobody sees
A waterproof membrane sits under the tiles in the shower and across the floor. Once the tiles are laid, you cannot see it. A labour-marketplace guide calls waterproofing the part you cannot cut, and says failed waterproofing is the most common reason Australian bathrooms get ripped out early.
How failure shows up
The guide says water creeps through the grout, soaks the substrate, rots the bottom plate of the wall frame and shows up as lifting floorboards or mould in the next room. By then the fix is usually a full redo. If you see any of those signs, ask a licensed professional to look before spending on cosmetic work.
What the standard asks for
The guide says in most states the membrane must be applied by a licensed or certified waterproofer, and that the work has to meet the National Construction Code and AS 3740, the Australian Standard for waterproofing domestic wet areas. In Queensland it says waterproofing has its own licence class. Ask each business for the licence details of whoever applies the membrane.
The cost line
The guide lists $1,000 to $2,000 for waterproofing in a mid-range bathroom, with a membrane certificate supplied. It is one line among many, and often small beside tiling or fixtures, but it is one that cannot be redone cheaply. Ask for it as a separate line on the quote.
Certificate and paperwork
Ask who applies the membrane, which product is used, how many coats, how long it cures before tiles go on and what paperwork you receive. Keep the certificate with your house records. A quote that says only that waterproofing is included, with no applicator or certificate, is a reason to ask more.
The order of works
The guide places waterproofing after the screed with falls to the drain, followed by curing, then tiling. If a quote seems to rush that stage, ask why. Ask when the membrane will be inspected, and whether you can see it before it is covered.
Shower areas and junctions
The guide describes the shower floor and walls being membraned to a set height, the rest of the floor receiving a membrane or water-resistant treatment, and bond breakers at wall-floor junctions. We offer no technical advice. Ask the renovator to explain each step in plain words.
Who holds the licence
The QBCC says plumbing and drainage need a licence at any value, and building work over $3,300 needs one too. Use the QBCC register to look up each licence details before you sign.
Heritage and older houses
Ipswich has a long history, and Wikipedia says more than 6,000 heritage-listed sites. An older floor may have layers that were never waterproofed. Tell each business the age of your home so it can plan.
Contracts
The QBCC publishes pages on contract types, which depend on the value of the work. Ask for payment stages tied to finished work, and keep any change in writing.
What to ask in writing
Ask for the name of the applicator, the licence details, the product, the number of coats, the cure time and the certificate. Ask whether the membrane will be photographed before the tiles go on. A business that keeps records is easier to deal with if a problem appears years later.
Why cost cutting here is risky
The guide lists waterproofing as a modest line beside tiles and fixtures, yet it says failure is the most common reason bathrooms are ripped out early. Saving a few hundred dollars on a line like this can cost a great deal later. Treat a very low price for this line as a reason to ask questions.
Questions to put to every business
Ask who inspects the work before tiling, what warranty covers the membrane and how long it lasts, and what the business will do if a leak appears. Get each answer in writing, and compare them across your quotes.
Keeping a record
Keep the certificate, the product name, photographs taken before tiling and the invoice together with your house papers. If a leak ever appears, those records show who did what, and a future buyer may ask for them.
Next step
Describe any damp, staining or lifting floors, along with the age of the house. Independent Ipswich renovators may contact you.
How much does waterproofing cost?
One guide lists $1,000 to $2,000 as one line in a mid-range bathroom, with a membrane certificate supplied. It is a national figure.
Who may apply it?
The guide says a licensed or certified applicator in most states, and that Queensland has a licence class for it. Check the QBCC register.
What standard applies?
The guide names AS 3740 and the National Construction Code. Ask the renovator to explain how the job meets them.
Can I see the membrane?
Ask to see it before the tiles go on, and ask for the certificate afterwards.
