Service
Remedial waterproofing for strata and commercial buildings.
Diagnosis and repair of failed waterproofing in occupied buildings. We work from the inside where possible, find the actual failure path, and specify the system that fits the substrate.
Remedial waterproofing is what happens when the original membrane has failed and the building is already occupied. The hard part isn't applying a new system — it's finding why the old one failed, specifying a replacement that will hold, and doing the work without displacing residents or shutting down operations.
On the Gold Coast and Northern Rivers, the most common failures we see are balcony and podium membranes in strata high-rises, rooftop membranes exposed to UV and salt air, and planter box membranes that have root-penetrated or delaminated. In each case the visible leak is often metres from the actual breach — water travels under the screed, along the slab, and exits at the weakest point.
First we find where the water is actually getting in. Is the failure localised — a single joint, crack, or penetration — or is the whole membrane compromised? The answer determines whether you need injection, a targeted patch, or a full membrane replacement.
What we remedy
Balcony and podium membranes
Failed top-side membranes on occupied strata buildings, replaced with minimal disruption to residents.
Rooftop membranes
UV-damaged and aged membranes on commercial rooftops, stripped and re-laid to specification.
Planter boxes
Root-penetrated or delaminated planter waterproofing, reinstated before internal damage spreads.
Wet area membranes
Failed shower and bathroom membranes behind tiles, diagnosed and re-waterproofed.
Construction joints
Leaking cold joints and expansion joints in basements and car parks — often paired with PU injection.
Penetrations and detailing
Failed detailing around pipes, drains and upturns where water finds its way in.
Diagnose first, then specify.
First we find the failure path with testing equipment and experience. Then the product and method follow from the substrate, the exposure, and the building's occupancy constraints — not the other way around.
Where the failure is localised — a crack, a joint, a single penetration — polyurethane injection is often the fastest and least disruptive fix. Where the membrane has failed broadly, we quote the replacement work honestly, using specified systems from our product partners.
