Car park deck waterproofing is a crucial element of the design for both new build and refurbishment of multi-storey car parks. A quality system will protect the exposed decks of the parking structure from water ingress causing structural damage, as well as providing a tough durable wearing surface that is skid-resistant and attractive.

Car parks are a busy environment and as such require heavy duty protection. They need to be able to resist the harsh de-icing salts brought in by the cars, exhaust fumes, chemicals, chlorides and UV exposure. If a deck is not protected properly then a serious maintenance issue arises for the car park owner and corrosion of steel supports could occur underneath the parking deck.

Dry Foundations: Exploring the Advantages and Options for Car Park Deck Waterproofing

There are a number of different solutions available to ensure car park decks have the best possible protection. Cold applied liquid systems are a good choice as they can be poured and set quickly to minimise disruption, and can be used on new and existing structures. These types of system are also capable of bridging cracks and joints often caused by movement or thermal expansion.

Other options include low viscosity epoxies that can be injected into cracks to structurally repair them and limit water ingress. This type of system is also able to be used in high traffic areas thanks to its abrasion resistance, as well as being able to be coloured to create demarcation lines and markings to control and regulate the flow of vehicles.
