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.
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.
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.

Features
|
Material Selection:
Movement Control Joints are available in mill finish aluminum, anodized aluminum, stainless steel and brass depending on the chemical, mechanical, electro-chemical or any other load to which the floor could be exposed.
Aluminum profiles are recommended for the common places and are not exposed to heavy chemical stress. Ideal for warehouses, airport, shopping malls, public buildings, hotels etc.
Stainless Steel and Brass profiles are recommended for the areas which are apart from the mechanical loads, exposed to high chemical stress like acid, strong detergents. It is also ideal for hygiene required and wet floor areas.
Insert available in EPDM, Vinyl Elastomer Compound according to the project requirements.
Insert Color: EPDM Black;
Vinyl Elastomer Compound Wide Range of Colors.
Standard Length Available in 2.50 meters.
Note: Customized movement joints can be produced upon request.
