Protecting Waterproofing and Simplifying Maintenance
The long-term performance of any waterproofed outdoor area depends on maintaining the integrity of the membrane system beneath. Once concealed below surface finishes, access for inspection or repair can be difficult and disruptive.
By supporting the finished surface above the waterproofing layer, raised flooring systems reduce direct traffic on the membrane while preserving access when required. Individual pavers, tiles or decking elements can be removed and reinstated without disturbing surrounding areas, simplifying maintenance and future repairs.
For enclosed weathertight deck constructions, maintenance access is also a regulatory consideration. E2/AS1 requires raised removable surfaces of tiles, pavers or timber decking over the underlying deck surface to facilitate cleaning and maintenance. Raised flooring systems provide a practical means of achieving this requirement while maintaining accessibility throughout the life of the deck.
This accessibility is equally beneficial where drainage infrastructure, irrigation systems, lighting or other services are located beneath the finished surface.
