The Need for Mechanical Fixing

Mechanical fixing is not required when thin format tiles are used, that is up to 10mm thick or products that weighs in at less than 32-38kg per m2. The other factor which is covering one and which has been set as the standard by the Glue and Fix Manufacturers at tile weight of no more than 4kgs per tile.

But, this has worried the likes of Ardex who have published a technical bulletin TB001.004 on 29/06/06. This informative bulletin does nothing but lift the need for products like StoneClip.

What mechanical fixing really gives you is:

  • complete peace of mind if fixed to manufacturer's specifications

  • takes out the worry of the tile failure if exposed to the elements

  • take out all chance of product releasing itself from substrate due to failure of material pulling off fix and fix tearing away from the substrate. both are possible on all surfaces when product weight exceeds 38kgs per m2

Example 1: Fixing of Stack Stone (with glue also used)

Sizes used:

600 x 400 x 40mm
600 x 240 x 40mm
600 x 45 x 40mm

Location:

Logan City Council
Administration Centre
Cnr Jacaranda Avenue and Wemberley Road
LOGAN CENTRAL QLD 4114

Example:

The walls constructed out of 40mm bush hammered beau brown sandstone. They were fixed onto a concrete block wall 3000mm high except for one lift that went to a height of 7800mm. All the panels had to be mechanically and as well glue onto substrate in a manner similar to the installation of Eco-StoneClip except that all panels had two clips attaching them.

Example 2: Full Mechanical Fixing with Open Joint 6mm

Sizes Used:

850 x 250mm
850 x 500mm
1600 x 300mm

Location:

Display Office of Kellyville Landscape Supplies
735 Windsor Road
BOX HILL NSW 2765

Example:

The below wall was constructed out of 50mm sawn face Sydney sandstone. It is cut across the bed so as to be laid on its natural bed (optimum cut). The sone used is in lengths of 850mm by varying lengths from 500mm to 250mm. All the fixings are visible in the joints. The lintels are 1600mm long by 300mm deep.

The clips were fixed to 16mm plysubstrate.

The clip spacings can be worked out by using the Clips Calculation page.

DISCLAIMER: The StoneClips must be installed along the lines of the Engineers Detail, including the installation of angle restraints at each lift level and the use of the right fixing restraints.
