Waterproofing Buried roofs/Podium Decks/Balconies & Terraces
In various formats podium decks have been around for many years, however they are becoming more widely used on top of basement constructions as either paved areas, gardens or terraces.
A podium deck is a structural element which is essentially an elevated platform which allows for usage both above and below, these may be terraces over underground car parks, gardens over basements, balconies over terraces and patios.
With their increase in popularity there is an increased need to ensure the waterproofing design is correct both for the above area use and the below deck use. Continuity of waterproofing and/or appropriate overlapping and detailing is critical for success.
The key to successful waterproofing is a robust design considered at the earliest stage of the project.

Considerations for the appropriate waterproofing products include:
