Waterproofing

Bathrooms and Wet Areas: What Good Waterproofing Looks Like

What to ask before the tiles go down.

1 October 2026

Bathrooms, laundries and kitchens all need waterproofing done properly.

Ask what system is used

Different membranes suit different situations. A good contractor can explain what they use and why.

Check the falls to drains

Water should always run towards the drain. Correct falls are part of a waterproofing job done well.

Allow curing time

Membranes need time to cure before tiling. Rushing this step puts the whole job at risk.

Keep records

Photos and paperwork of the waterproofing stage are valuable later, especially when selling or for future maintenance.
