Product Description

Maruti expansion joint consists of steel armored nosing at two edges of the joint gap suitably anchored to the concrete deck and a preformed EPDM/Polychloroprene elastomer compressed and fixed into the joint gap with a special adhesive binder. The seal is supposed to remain in continual compression due to pressing of the seal wall against joint faces throughout the service life to ensure that the joint remains watertight and capable of repelling debris.
 
The prime functional requirement of a joint is to cater to movements with very low resistance or with no resistance at all. The design of the expansion joint is capable of accommodating all movements of the deck viz. translation and rotation, and also capable of all loads acting on it and local actions under all weather conditions.
 
The expansion joints perform the following basic functions
 

• Should permit the expansion and contraction of the span to which it is fixed without causing any distress or vibration of the structure
• Cause no inconvenience to the road user and offer good riding comfort
• Should be capable of withstanding the traffic loads including dynamic effects
• Should be watertight and capable of expelling debris without clogging
