Attention to Detail
Corners, junctions, penetrations and hobs — the places leaks actually start — are never an afterthought.

About Metroseal Waterproofing
A waterproofing contractor working across residential, commercial and industrial projects, Australia wide.
Our Story
Waterproofing Done Properly
Metroseal Waterproofing is a waterproofing contractor working across residential, commercial and industrial projects Australia wide. With 10+ years of experience, we've built our reputation on getting the detail work right — the corners, junctions and penetrations where most waterproofing failures start.
We specialise in internal wet areas and remedial work, but the same approach carries through everything we do: correct systems, correct build-up, and a job that's documented and flood tested before anyone tiles or backfills over it. We work directly with homeowners, and alongside builders, tilers and strata managers on larger projects.

How We Work
Four Steps, No Surprises
The same process on a single ensuite as on a full commercial deck.
Site Inspection
We look at the substrate, falls and drainage, check for existing moisture, then put the scope in writing with a fixed price.
Preparation
Grind, clean and prime. Bond breakers to movement joints, fillets to internal corners, penetrations sealed before a drop of membrane goes down.
Membrane Application
Coats built up to the specified thickness with reinforcing where it's needed, upturns to height, and full cure time between coats.

Wet areas flood tested before the tiler starts. You get the photo record and your waterproofing certificate.
