Movement Joints
Although at first glance thet dont appear to move, tiles,screed and concrete are "living" materials. Even massive structures made of these materials are constantly subject to form changes (deformation). Such deformations are caused by drying, loads,changes in moisture content and temprature fluctuations, which can combine and compound one another.
To ensure that deformation does not cause damage, screed and covering assemblies e.g., tiled floors must include movement joints, which allow movement to occur limiting stresses causing damage to the covering.
Structural Joints
(Expansion joints) are joints required for static or engineering reasons, which divide a building in various movement segments. The run through all load bearing and non load bearing parts of a building and must be continued in the screed construction and the floor covering at the identical location and in the specified width.
Intermediate Joints
Create a pattern of limited fields in large areas of screed and covering. They must be continued from the surface of the covering to the seperating layer under the screed or to the covering of the insulation or waterproofing layer. In door transition areas, the screed should contain movement joints, which are continued in the covering to reduce stresses occurring at these locations and to prevent the transmission of impact sound. Movement joints in the substrate may not be closed or covered with flooring materials.
Perimeter Joints
Are movement joints placed in the screed and the covering along walls and construction elements that penetrate the screed, such as columns. They reduce impact sound transmission ans absorb the movement of the floor assembly. Edge joints may not be rigidlt closed, since this may lead to the formation of sound bridges and tension in the covering construction.
Connection Joints
Are movement joints placed in the screed and the covering at construction elements such as window openings, door frames, shower trays and bath tubs.
