Quality You Can Measure
At Wattaproofing Excellence, waterproofing isn’t guesswork, it’s real precision. Our philosophy is simple:
do it once, do it right.
We specialise in residential, strata and commercial waterproofing across Sydney, delivering systems that are tested, certified, and built to last. Every membrane we install is measured using the PosiTector 200 to confirm thickness and compliance with Australian Standards. When we say watertight, we prove it.​
