Seals of Movement Joints and Gaps in Floors and Walls

ADVANTAGES

Building movement from not only thermal and moisture effects but also wind and seismic forces is one of many factors which must be considered by engineers. Joint size, therefore, is likely to be a difficult decision to make in many instances if detailed investigations are not made.

On the other hand, joint size and shape may often be predetermined by the profile of prefabricated purpose-made components or products. Where this is not the case, however, the shape of the joint should be designed to take into account factors such as the magnitude and direction of anticipated movement in adjoining components, type of stress expected, the need for seals to maintain integrity, accessibility for inspection, maintenance and replacement if necessary. For more information, please consult Promat.

These typical applications include:

  • Joints between old and new constructions that are aligned, i.e. the existing building is being extended.
  • Joints in floor slabs that are used for vehicles and require a high degree of flexibility.
  • Gaps between floor slabs and fascia panels.
