A raised access floor is ideal for floors which are to built over installations that may require periodic inspection or modification. It is extremely useful for the type of constructions featuring numerous fixtures that potentially require regular maintenance. A raised access floor system consists of a platform of panels supported on adjustable pedestals, thus creating an empty cavity that facilitates the laying and handling of installations in buildings.
Outdoor Raised Floors
For outdoor raised floors, the basic components are tiles and pedestals. • Tiles: in this case, porcelain stoneware tiles are used, which, thanks to their increased 20mm thickness, boast high mechanical performance. • Pedestals: to support the panels. They are plastic, height- and gradient-adjustable, and they determine a minimum joint that allows water drainage in the system.
After finishing the waterproofing, drainage and laying the screed, carefully clean the substrate.
Adjust the pedestal height in-situ, bare in mind the maximum height of the pedestals (in the drains) and the minimum heights (perimeters: vertical barriers, and access points to the deck or terrace). Fix the pedestals in place using a polyurethane adhesive, following the designs provided by grespania’s technical department.
Step 3 Place the tiles one by one with all four corners, as a minimum, resting on a pedestal. The number of pedestals to use will always depend on the chosen format and the mechanical strength required.
Step 4 Complete installation remembering to leave access points.
