How Sealite Began.
Sealtite was founded in 2014 in Melbourne with a simple belief: waterproofing is not a finishing trade — it's structural. Get it right and a building lasts a lifetime. Get it wrong and it rots from the inside out.
From a two-person operation working bathrooms in the eastern suburbs, we've grown into a specialist crew of ten covering everything from below-grade basement tanking to 24-storey commercial facades. Every trade we hire is trained in-house on the standards we care about — AS 3740, AS 4654, and the manufacturer specs from Ardex, Sika and Bostik that our warranty depends on.
We don't pitch tiles, cabinetry or paint. We waterproof. That focus is why builders, owners corporations and homeowners across Melbourne trust us with the invisible layer that holds everything together.
“Every job we hand back has our name on it. That's why we obsess over the details nobody else looks at.”
3 principles that run every job.
Do it once, do it right.
We don't do rework. Every project is scoped, prepped and installed to manufacturer spec — the first time. Our 10-year workmanship warranty exists because we back what we build.
The details matter.
A membrane is only as good as its weakest joint. We treat every corner, penetration and threshold as a potential failure point — and detail it accordingly. That's the whole job.
One crew, start to finish.
No subbies, no revolving door. The same in-house Ardex-accredited team walks your site, preps the substrate, lays the membrane and hands you the certificate.
