Industry standards state that all tile and stone installations should include the use of movement joints.
They need to go through the tile and screed covering and therefore need to be designed at specification.
Understanding the types of movement that can occur, namely drying shrinkage, differential movement, deflection movement, structural movement, moisture movement and thermal movement, will help when deciding which type of movement joint will best counteract the resulting stresses.
Pre-formed joints can accommodate roughly 15-20% of their movement zone. The Schlüter-DILEX range of movement joints offer complete protection and are available to specifiers in a wide selection of materials, colours, and movement capability.
