Hidden water damage is one of the costliest threats facing Melbourne property owners. Think foundation cracks in a weatherboard home in Glen Waverley, or rising damp creeping into the bluestone footings of a Victorian terrace in Fitzroy. At Metrobuild Building & Construction Suppliers, we stock the trade-quality waterproofing supplies Melbourne builders, remediators and renovators rely on to stop water ingress at its source.

Our Springvale showroom carries complete, code-compliant systems for residential, commercial and inter-tenancy projects. We’re also open for 7 days. We make it easy for trades and homeowners to get the right products, backed by hands-on technical guidance from people who’ve been on the tools.

Waterproofing Membranes & Primers for Melbourne’s Climate

Melbourne’s “four seasons in one day” puts enormous strain on external membranes. Sudden downpours, rapid temperature swings and harsh UV exposure can chew through inferior products in just a few years, which is exactly how you end up with balcony leaks and premature membrane failure on modern builds in Southbank, Docklands and Box Hill.

We supply Waterproofing membranes & primers engineered for these conditions, including:

• Liquid-applied flexible membranes for balconies, planter boxes and rooftops
• Topcoats with UV stability for exposed external surfaces
• Bituminous and polyurethane systems suited to podium decks and split-slab applications
• Primers, bond breakers and reinforcing fabrics that work as a matched system

Building a high-rise apartment? Upgrading an external deck at home? Either way, our team will help you match the membrane to the substrate, exposure and movement profile. Drop into the showroom for a hands-on look at how each system performs, or call us for product selection support today.

Internal Wet Areas & Bathroom Waterproofing

Bathroom and laundry leaks are some of the most common defects in Australian construction, and easily the most expensive to fix. Every wet area has to comply with AS 3740-2021 and Victorian Building Authority (VBA) requirements. That’s non-negotiable for any renovation, new build or volume project.

Complete Wet Area Systems

We stock full Internal wet areas & bathroom waterproofing systems for projects of every scale, from a single ensuite refurb in a Carlton terrace through to multi-unit developments out in Tarneit, Cranbourne and the south-east growth corridor. Our range includes:

• Class III liquid membranes for bathrooms, ensuites and laundries
• Waterproof tapes, bond breakers and corner reinforcement
• Tiling adhesives and grouts that play nicely with the membrane systems
• Pre-formed shower bases and waste fittings

Our team also helps with technical documentation and product compatibility, so trades, builders and owner-builders can be confident their wet area passes inspection first time round. Tiling a single bathroom or coordinating wet area trades across a townhouse development? We’ll help you specify the right system.

Your Local Waterproofing Suppliers in Melbourne

Across Greater Melbourne’s 31 local council areas, building types and site conditions vary dramatically. A heritage terrace in St Kilda asks for a very different approach to a brick veneer in Preston, or a high-rise apartment in Southbank. Our team gets these differences and gives you product-focused guidance tailored to your project.

We work with builders, sub-contractors, plasterers, tilers, renderers, cladders, remediators and clued-up homeowners across:

• South-East Growth Corridor: Glen Waverley, Clayton, Dandenong, Keysborough, Noble Park, Cranbourne, Pakenham, Officer, Berwick, Clyde
• Western Growth Corridor: Truganina, Tarneit, Werribee, Point Cook, Melton
• Northern Growth Corridor: Craigieburn, Mickleham, Epping, Wollert, Donnybrook
• Inner & Commercial Zones: Richmond, South Melbourne, Port Melbourne

Our products meet and exceed AS 3740-2021 and AS 4654.2-2012, with codemark and certification documentation available for compliance and quality assurance. Working with heritage considerations, or specifying a system for a volume build? Drop into our Springvale showroom or contact our team to talk it through.
