A concrete expansion joint is a continuous horizontal or vertical joint Sealants used to compensate for the expansion and/or shrinkage that occurs in the construction materials due to temperature changes, to prevent the passage of media such as air, water, chemicals, smoke, etc. to provide thermal and sound insulation and to enhance the visual appearance of a structure. The joint is filled with an elastomeric expansion joint sealant which is soft and able to accommodate the concrete slab’s expansion and connection and prevent water from penetrating the joint and deteriorating the sub-base.

Using a joint sealant to seal expansion joints and contraction joints in concrete walls and floors help maintain the integrity of a concrete structure. Concrete joint sealant in concrete floors protects the expansion joint from damage, such as chipping and cracking, caused by heavy equipment, moisture, rain, gravity, wind, surface tension, and capillary action.
