Car Park Deck Waterproofing

Car Park Deck Waterproofing is essential for the effective and long term protection of concrete car park decks. Whether in new build or refurbishment, all voids must be sealed and waterproofed and the system should be capable of bridging thermal movements, be durable and hard wearing to withstand damage from vehicles and abrasion from salts and de-icing chemicals. It is also necessary for the waterproofing deck coating to provide skid resistance, demarcation of parking bays and walkways as well as be aesthetically pleasing.

On existing car park structures, a professional condition survey must always be undertaken to assess the nature and extent of any damage and/or defects. Ideally, these will be repaired prior to the waterproofing works commencing. However, if repairs are not possible then the deck surface must be mechanically prepared (using vacuum blast cleaning), to remove any contamination and ensure good adhesion to the new resin waterproofing system.

Seal and Shield: The Essentials of Car Park Deck Waterproofing

There are a number of different waterproofing deck coating systems available for car parks. These range from cold-applied liquids to mastic asphalt and are suitable for either new or refurbishment projects. They are all engineered to deal with the specific stresses and pressures imposed on the car park structure including dynamic crack cycling, chemical attack, UV exposure, impact damage and shear forces. These systems are able to provide effective long-term waterproofing, retain skid resistance and remain bonded to the substrate. They can also be designed to allow for the incorporation of drainage systems within the structure and have excellent fire rating qualities.
