Ceramic tile rail substructure system

by Wallbarn Ltd

Laying ceramic tiles on flat roofs, terraces and podium decks has been made easier with the development of the Rail System, an integrated substructure system to increase stability of suspended tiles.


The Rail System incorporates an adjustable height pedestal with a special clip head fitting, a specially profiled aluminium rail which clicks onto the headpiece without the need for mechanical fixings and a top headpiece which slides along the rail to hold and position the tile.


By tying the pedestals together via the rail, there is far less risk of an individual pedestal moving or changing height, leading to far less risk of a tile rocking over time. This assures the integrity of the upper surface and gives a health and safety improvement to the area.


The rail gives added structural stability as the weight is distributed laterally along the rails and not driven directly downwards onto the pedestal beneath.


The top headpiece can be slid along the rail to fit to the corners of the tile above. This means the edge of the tile does not necessarily have to be directly above the pedestal, giving much greater flexibility for positioning.

Consider the possibility of a drainage outlet or other awkward detail being directly beneath the edge of a surface tile. Instead of having to cut the tile back, simply move the pedestals away for the outlet and let the rail circumvent the hazard. Position the top head in the correct place to fit around the corner of the tile and the issue is addressed quickly, securely and easily.


The rail system brings greater lateral stability to the tiled deck and is a faster, more efficient way to lay porcelain tiles and slabs.

It is a major technical improvement to suspended tile and slab installations.
