Car Park and Waterproofing Remediation Sydney

Car park remediation for Sydney assets: Car parks, podiums and rooftops repaired and re-waterproofed to the specification

• Car park decks, podiums, basements and rooftops repaired
• Concrete repair to the engineer's specification
• The specified membrane installed with hobs, upturns and drains
• Staged bay by bay inside fenced exclusion zones
• CBD, North Sydney, Chatswood, Parramatta and council car parks
• No strata, balcony or home waterproofing work

Yes, Perfect Remediation repairs and re-waterproofs commercial and council car parks, podium decks, basements and rooftops across Sydney. The membrane has failed, the deck is spalling and the car park has to stay open: we find the source, repair the concrete, re-waterproof to the specification and stage the work around the traffic. Where we draw the line is set out below.

What we repair and re-waterproof

Water gets through a failed membrane, sits on the reinforcement and the deck spalls. Patching the concrete without fixing the membrane means patching it again, so one scope covers both:

• Car park decks: spalling and concrete cancer repair to the engineer's specification, breakouts cut square, reinforcement treated, patch reinstated, control joint bandages repaired.
• Podium decks and rooftops: failed membrane investigation, then the specified sheet or liquid membrane with hobs, upturns, drains and falls made good.
• Basements: concrete repair and protective coatings to walls and slabs.
• Council assets: below ground tanks, culverts, pool structures and car park decks.
• Terraces, planter boxes and plant decks on commercial buildings: the leak traced to its entry point and rebuilt.

Joint and crack repairs are steps inside a deck repair; where joint sealing or crack injection is the whole job, Perfect Concrete Care's pages are linked below. For beams, columns and propping see structural concrete remediation Sydney.

Where this work happens in Sydney

Sydney's car park and podium work sits where the buildings are dense and the decks are old. The CBD, North Sydney, Chatswood, Macquarie Park and Parramatta hold basement and rooftop car parks under office towers and hotels, podium decks over retail and loading docks, and rooftop plant decks last waterproofed decades ago. Council multi level car parks sit in every local government area from Blacktown and Campbelltown to the Northern Beaches, and council pools and civic centres carry below ground tanks and roof decks of their own. Ingleburn and the south west industrial belt hold head offices with terraces over car park entries. Near the harbour and the beaches salt air gets into unprotected decks and chloride driven spalling shows early. That is the ground we cover.

Crews and gear come out of our Marrickville base, so an estimator can walk the deck with you before the price goes in. Our published jobs in this lane are at Artarmon, the CBD, Ingleburn, Wentworthville and Collaroy, all Sydney.

Our published jobs in this lane are separate stories. At the SBS car park at Artarmon a five storey car park in daily use was repaired in stages so there were always enough car spaces available. On the Sofitel Sydney Wentworth rooftop a new PVC membrane and liquid membranes went down, the perimeter hobs were repaired, new rooftop stormwater drains went in and a raised paving system went over the top, hotel trading. At Bromic's Ingleburn head office the leak was traced to a terrace with no membrane under the sill and rebuilt; the Cumberland Council balance tank had a membrane applied to its walls and floor; the Collaroy basement had its sheet pile walls coated. No single published job combines a car park deck and a new membrane. References are available on request.

How we do it

The sequence on any deck:

• Investigate. Start from the engineer's report or the leak: delamination survey and tap testing to the engineer's scope. Each area is marked and photographed before cutting.
• Stage. Fenced exclusion zones, dust and debris control, night or weekend windows where noise matters, lift and loading dock access agreed with the operator, so bays stay open.
• Repair the concrete. Breakouts to the engineer's specification, reinforcement treated, repair mortar reinstated, hobs and upturns rebuilt, propping where called for. A defect bigger than expected is recorded and goes back to the engineer.
• Re-waterproof. Substrate prepared, the specified membrane installed with upturns, hobs, penetrations and drains detailed, falls made good, paving or finishes reinstated.
• Record. Every breakout and membrane area logged and photographed against the ITP, with weekly reporting, so your asset engineer gets a handover pack.

Before you ask for a price

What to send:

• The engineer's report or waterproofing specification, if any.
• Where it leaks and what sits underneath.
• A drawing or sketch of the deck with the area, hobs, drains and joints.
• How many bays must stay open, hours, noise windows, lift and loading dock access.
• Access: heights, scaffold or EWP, inductions and permits.

Those decide most of the cost. No report yet? Send photos.

What we do not do

We do not take strata, owners corporation, apartment balcony, unit or home waterproofing work; if that is your building we will point you elsewhere. We are not membrane specifiers; your engineer or waterproofing consultant sets the system and we install it. Where the whole job is taking off an old membrane, that is Perfect Concrete Care's lane, linked below.

Common questions

Who specifies the membrane and the repair?

Your structural engineer or waterproofing consultant. We price to that specification and install the system it names. No specification yet? Tell us where it leaks.

Does the car park have to close while you work?

Usually not. Repairs are staged bay by bay inside fenced exclusion zones. The SBS car park at Artarmon stayed open through its repairs.

What if the old membrane contains asbestos?

The Sofitel rooftop membrane tested positive. A safe methodology is agreed first, the old membrane is handled by Perfect Contracting, another Perfect Group division, and we re-waterproof once the deck is clear.

Can you work on a live hotel or office rooftop in the CBD?

Yes. The Sofitel Sydney Wentworth rooftop was re-waterproofed while the hotel traded: access through operational goods lifts and live hallways, noisy works stand downs and limited loading dock access.
