Outdoor Raised Floors

RAISED ACCESS FLOORING FOR EXTERIORS

The raised access floor (RAF) system for terraces has been specially created to provide an aesthetic solution for terraces containing unsightly drainage slopes. By building a completely flat floor over the existing terrace floor, these slopes are conveniently hidden underneath. Height deviations are offset with height-adjustable plots and any accumulated water is drained through open joints on the newly paved surface and then channeled down the terrace's waterproofed slopes to the drain.

 

ADVANTAGES

  • The system can be used to create a flat paved surface over sloping masonry floors with height deviations of up to 2%. Any height deviations over 2% will need to be corrected with mortar or with wedges.
  • The creation of an air void under the newly paved surface generates a continuous flow of air through the pavement joints, which prevents the build-up of condensation and also produces an insulation layer.
  • The under floor void, can also be used to house cables, pipes, etc.
  • Easy to access this space under the floor (do not use P-404 to bond tiles and plots in areas where you need to access the services underneath).
  • The cavity between the raised floor and the living area below also helps to reduce the penetration of noise into the home.
  • The system is quick to install as the tiles and supports are installed at the same time.
  • Advantages of Ston-Ker: Easy to clean, low dimensional tolerances, wide variety of finishes, hardness, etc.

COMPONENTS FOR EXTERIORS

RAFs for exteriors are flooring systems that incorporate special ceramic tiles on PVC pedestals of adjustable heights, so that a certain space is left between the substrate and the tiled surface. This kind of floor is typically used for terracing and on flat roofs subject to low to medium pedestrian traffic. The system is made up of pedestals of adjustable heights and special tiles for exterior RAFs.

PEDESTALS

The PVC pedestals act as a support for the tiles and also determine the height of the system and width of the tile joints. They can range in height from 10 mm to 580 mm. In addition to the final height of the base structure, the thickness of the tiles must also be calculated.

CERAMIC TILES

Special ceramic tiles for exterior RAFs are double porcelain tiles glued together with a flexible adhesive with a high bonding strength. The resulting tiles are thick enough to comply with the breaking strength required for this type of raised access flooring.
