Commercial waterproofing Sydney

Commercial buildings don’t pause because a membrane failed. Tenants still use the wet areas. Plant still sits on the roof. Water still finds the joint.

Sydney Waterproofing Services delivers commercial waterproofing across Greater Sydney — rooftops, plant decks, wet areas, balconies/podiums, planter boxes and remedial packages on existing assets. Seven Hills base. On-site diagnosis. Written scopes. Crews that work around access rules.

What we waterproof on commercial sites

• Rooftops & plant levels — torch-on, sheet and liquid systems; penetrations; upstands; ponding call-outs
• Podiums & terrace decks — membranes under finishes; falls; outlets
• Wet areas — amenities, end-of-trip, kitchens, laundries to AS 3740 thinking
• Balconies / façade decks tied into the commercial envelope
• Planter boxes on podiums (frequent leak source)
• Remedial repairs where coatings or membranes have already failed
• Caulking & joint sealing as part of the system — not a substitute for a dead membrane

Materials from trade ranges we already use: Ardex, Bostik, Mapei, Gripset, Crommelin, Soprema, Drizoro and others matched to substrate and exposure.

Why commercial jobs stall (and how we keep them moving)

1. Unclear ingress path — we inspect before we sell a full recover.
2. Access & OH&S — inductions, SWMS, site rules; we work within them.
3. Tenant disruption — phased wet-area or roof works where the program allows.
4. Budget staging — priority areas first when the whole envelope can’t be done in one FY.

Sydney commercial notes

Storm cells overload flat roofs that already pond. UV cooks exposed membranes on plant decks. Amenities blocks in older stock often pre-date current wet-area detailing. Retail and office podiums with planters are regular claim generators.

We cover Greater Sydney from Seven Hills — not a fly-in crew that disappears after invoice.

When to call us today

• Active roof leak over tenancies or plant
• Amenities fit-out needing compliant membranes
• Podium leaks into car park or retail below
• Defect list from a building audit
• Need a trade to work with your builder’s program

FAQ

Do you work after hours?

Where site rules and the scope need it, programs can include out-of-hours stages. Ask when booking.

Can you work to a principal contractor’s WHS system?

Yes — inductions, SWMS, permits as required.

Is this different from your residential work?

Same trade standards; different access, documentation and staging. Same phone number.

Do you only do membranes, or finishes too?

Membrane is the core. Tiling and sealing are available so junctions aren’t split across three subcontractors unless you want that.

Where are you based?

Factory 29, 6 Abbott Road, Seven Hills NSW 2147.
