Movement Control Joint System

 

A Movement Joint is an assembly designed to safely absorb the temperature-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes.

  • In building construction, an expansion joint is a mid-structure separation designed to relieve stress on construction materials occurred by building movement due to:
  • Thermal Expansion & Contraction because of the change in temperature within the structure.
  • Building sway caused by strong winds
  • Seismic events
  • Settlement in structure.

 

Movement Joint Systems are used to bridge the gap and restore building assembly functions while accommodating expected movements.

The term “Movement Joint” has been widely adopted in preference to “Expansion Joint” as it is more appropriately encompasses the fact that building movement results in both compression and expansion of materials installed.

 

Movement Joints are ideally installed for both Indoor & out door application, in all types of hard flooring areas, like ceramics paving, granite, marble, wood and all mortar laid floors etc.

 

Movement Joints are recommended to be provided for any one or more of the following minimum conditions.

  • When the floor plan size exceeds 200 feet in any direction.
  • For structural expansion or contraction joints.
  • Where the deck material changes, for example from steel to concrete.
  • Where building wings intersect, such as “U”, “T”, or “L” shapes.
  • Where interior heating and cooling conditions change.
  • At all building additions of any shape. 

Movement Joints are typically used in concrete masonry to reduce the occurrence of shrinkage-related cracking. An Expansion Joint is a continuous vertical or horizontal joint filled with mortar, but with a bond breaker on one side so that tensile stress cannot develop across the joint. If expansion joints are not provided, a concrete masonry wall or floor may crack as it shrinks over a period of time. Where expansion joints are provided in such a wall or floors, they widen as the concrete masonry shrinks, preventing it from cracking.

MATERIALS USED

The Movement Joint profile metallic part is made of the base metals like, Aluminum (Mill Finish / Anodized) Stainless

Steel (304/316 Grade) and Brass.

The Movement Joint profile insert part is made of various materials like, EPDM, Vinyl Elastomer Compound.

 

Movement Joint materials are selected as per the project specific requirements and specifications. Customized movement joints can be produced upon request.
