North Ryde NSW 2113
Searching for experienced waterproofers in North Ryde? We specialise in waterproofing services in North Ryde for homeowners, landlords, builders and strata managers. From bathroom leaks to balcony and basement repairs, our licensed team gets it right the first time – free inspection, written quote, 7-year warranty.
Like much of the northern suburbs, North Ryde is a mix of family homes to apartments and offices near Macquarie Park. Whatever the building, water finds the weakest point – a cracked grout line, a failed door sill, a blocked outlet or an unsealed joint – and the damage often shows up a long way from where the water gets in.
Every job starts with finding out exactly where the water is coming from. We then recommend the simplest fix that will last – whether that’s tile injection, a remedial membrane or a full strip-out – and explain the options clearly before you decide.
From inside the bathroom to the roof and below ground, we waterproof it all in North Ryde. These four services are the ones we’re asked for most often.
Showers & en-suites
Whether you’re renovating or chasing a leak, the membrane under the tiles is what keeps water where it belongs. We install certified wet-area membranes with bond-breakers, reinforced corners and properly sealed penetrations, then issue a compliance certificate for your records.
Outdoor areas
Leaking balconies are one of the most common strata repairs we do. We re-waterproof balconies and terraces with minimal disruption, keep residents and managers informed, and provide a written warranty for the owners’ corporation records.
Basements
Water pressure behind a wall never stops, so below-ground waterproofing has to be continuous – walls, slab and the joint between them. We seal construction joints and penetrations, then apply a membrane designed for constant moisture.
Pools
A pool membrane protects more than the water level – it stops water soaking into the surrounding ground, paving and structure. We waterproof concrete pools and spas with flexible systems suited to constant immersion and pool chemicals.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
Brick walls, parapets and chimneys sealed against rising and penetrating damp to stop salt damage, flaking render and mould inside.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.

Often, yes. If the tiles are still well bonded, tile injection seals the leak from underneath without demolition. If the membrane has failed completely, we’ll explain why a strip-out is the better long-term fix.
Most balcony leaks start at the door sill, the drain or the balustrade fixings, where the membrane has cracked or was never properly detailed. We find the failure point and re-waterproof the balcony properly.
Yes. All work is carried out under Waterproofing Licence 36763C, and we’re happy to show it on site. A licensed waterproofer matters for insurance claims, strata approvals and selling your property.
Most shower and balcony repairs take a few days including curing time; tile injection is usually done in a day. Larger roofs, basements and strata jobs are scheduled in stages – we’ll give you a timeframe with your quote.
