Industry guidelines for ceramic and stone coverings require movement joints to be placed at all perimeters and where tiling meets restraining surfaces such as steps, kerbs, columns and fixed plant etc.
Intermediate movement joints should be placed in accordance with the covering requirements, which for ceramic tile and natural stone is between 8-10 metres in each direction. Ideally the tile fields should be kept as square as possible.
Where underfloor heating is installed within the screed layer, movement joints should be used to divide the tile fields into areas of no more than 40 square metres, with the longest side no more than eight metres.
The movement joints should pass through the covering, adhesive bed and screed.
Movement joints should be placed in the screed in accordance with industry guidelines, however, because of the difficulty of forming such joints in the required precise location while the screed is being laid, it is advisable to form intermediate joints in non-heated screeds by using a dry cut floor saw to cut through the screed when the tiling is being installed.
The structural movement joints in the bed and tiling should be sited immediately over, and be continuous with, the joints in the base.
This is just a brief overview of what is needed for a successful ceramic or stone installation on an anhydrite screed. For contractors who are in any doubt whatsoever about any aspect of tiling onto these calcium sulfate-based screeds - Schluter-Systems, who are members of both The Tile Association and the Contract Flooring Association - will be happy to advise on the suitability.
