Yes. We remove waterproofing and membranes in Wollongong. Commercial and industrial only, removal only, and we hand the slab back ready for the next system.

If you have an old, failed or wrong waterproofing membrane that has to come off a concrete deck, car park, plant room, podium or wet area in Wollongong and the Illawarra, Perfect Concrete Care does that work. Tell us what is on the slab and what is replacing it, and we will tell you the method, the programme and the price.

Wollongong enquiries: call 02 8015 6398 or use the form at the bottom of this page. Our Sydney team handle the job from our Marrickville base, about ninety minutes up the road.

What we remove in Wollongong

• Sheet membranes. Torch on bitumen, self adhesive and bonded sheet systems off decks, roofs, podiums and planters.
• Liquid applied membranes. Polyurethane, acrylic, cementitious and hybrid coatings off wet areas, balconies, plant rooms and car parks.
• Failed and delaminating waterproofing. Where the system has let go and the new applicator will not warrant over it.
• Old coatings under the membrane. Epoxy, sealers, adhesive and screed residue, ground back to sound concrete.
• Wet area strip back. Commercial bathrooms, kitchens, laundries and change rooms in offices, hospitals, schools, hotels and retail.

We do the removal and the surface preparation behind it. We do not install waterproofing. Your applicator gets a clean, sound, profiled slab they can warrant, which is the whole point of doing the removal properly.

Where this work happens in Wollongong

Car park decks and ramps. Rooftops and plant rooms. Podiums and planter boxes over habitable space. Balconies and walkways on commercial and strata buildings. Loading docks. Wet areas in hospitals, aged care, hotels, schools and offices. Anywhere a membrane has failed, is the wrong system for the new build, or has to come off so a defect can be fixed underneath.

We work across Wollongong, Port Kembla, Shellharbour, Kiama, Dapto, Unanderra, Nowra and the Shoalhaven, and the escarpment suburbs.

How we take it off

The method depends on what the membrane is, what it is bonded to and how much of the surrounding building is still in use.

• Diamond grinding for thin liquid systems, coatings and residue, with captive dust extraction.
• Scabbling and scarifying for thick, well bonded or multi layer systems and for bringing the slab to the profile the new membrane needs.
• Heat and hand stripping for torch on and sheet systems where mechanical removal would damage the substrate or the falls.
• Shot blasting on large open decks where the programme matters and the surface has to come up uniform.

Dust is controlled with on tool extraction and HEPA vacuums, water where the substrate allows it, and containment where the building is occupied. Concrete dust carries respirable crystalline silica and we treat it accordingly. Waste is bagged, classified and removed, with dockets.

Before you ask for a price

Three things get you an accurate number quickly. What the existing membrane is, if you know. Roughly how many square metres. And what is going back on, because the new system dictates the profile we leave. A photo of a corner where the membrane has lifted tells us more than a paragraph.

If there is a suspicion of asbestos in an older membrane or the screed under it, say so. Perfect Group holds the licences and we handle it in house, but it changes the method and the price.

What we do not do

We do not install or re-apply waterproofing, we do not do residential bathroom renovations, and we do not do DIY advice. If you are a homeowner looking to strip your own shower, a tiler or waterproofer is the right call. If you are a builder, a strata manager, a facilities manager or a waterproofing applicator with a commercial slab that needs the old system gone, you are in the right place.

Common questions

Do you remove waterproofing membranes from residential bathrooms in Wollongong?

No. We work for builders, strata and facilities managers, waterproofing applicators and head contractors on commercial and industrial slabs. A homeowner stripping a shower is better served by a local tiler or waterproofer.

How long does membrane removal take on a typical commercial deck in Wollongong?

It depends on the membrane type, its thickness and how well it has bonded. Sheet membranes come off faster than well bonded liquid systems. Once we know the area, what is on the slab and your access hours, we give you a programme with the price rather than a guess.

What condition is the slab left in after removal?

Clean, profiled and ready for the next system, with any loose or drummy material identified. If the slab needs patching, levelling or crack repair before the new membrane goes on, we do that as part of the same job so there is no gap between trades.
