Basement car park waterproofing
Waterproofing membrane applied to a basement car park, protecting the concrete walls and structure from water ingress.
Protect concrete structures from water damage
Concrete car parks are constantly exposed to vehicle traffic, rain, UV exposure, oils, chemicals and temperature changes. Without a properly designed waterproofing system, water can penetrate the concrete, leading to reinforcement corrosion, cracking, concrete spalling and costly structural repairs. TN Stone installs high-performance trafficable waterproofing systems designed to protect both exposed and suspended concrete car park decks while extending the life of the structure.
Left untreated, water ingress can lead to concrete cancer, reinforcing steel corrosion, water leaks into lower levels, efflorescence, structural deterioration, expensive remediation works and safety hazards. Waterproofing systems for external horizontal surfaces are generally designed and installed in accordance with the National Construction Code and the relevant Australian Standards, including AS 4654.1 and AS 4654.2 where applicable.

Car park waterproofing questions
Is car park waterproofing installed to Australian Standards?
Trafficable waterproofing systems for external horizontal surfaces are generally designed and installed in accordance with the National Construction Code and the relevant Australian Standards, including AS 4654.1 and AS 4654.2 where applicable.
What is the difference between a trafficable and a standard membrane?
A trafficable membrane is engineered to withstand vehicle traffic, UV exposure and abrasion in addition to keeping water out, and generally includes a protective wear coat and anti-slip finish.
Can a car park be waterproofed without closing it completely?
In many cases, works can be staged section by section to reduce disruption, depending on access, traffic requirements and the extent of repairs needed.
Do you repair cracked or spalling concrete before waterproofing?
Yes. Concrete repairs, crack treatment and crack injection are completed as part of surface preparation, so the membrane is applied to a stable, sound substrate.
What waterproofing system is best for a car park?
It depends on the structure, exposure and traffic. TN Stone installs polyurethane, epoxy, polyurea, MMA and cementitious systems, and specifies the right one after a site inspection.
Do you waterproof basement and multi-storey car parks?
Yes. TN Stone waterproofs basement car parks, multi-storey car parks, suspended slabs, podium decks, driveways and ramps for commercial, residential, industrial and strata properties.
