Rubber Expansion Joint Manufacturer in Indonesia
IRC INOAC Indonesia is a trusted rubber expansion joint manufacturer in Indonesia, delivering high-quality elastomeric solutions for bridge, building, and infrastructure projects. Our rubber expansion joints are engineered to accommodate structural movement, reduce stress, and extend the service life of concrete and steel structures.
What is a Rubber Expansion Joint?
A rubber expansion joint is a flexible elastomeric component installed between structural elements to absorb movement caused by:
Temperature changes (expansion & contraction)
Traffic loads and vibration
Seismic activity
Shrinkage and creep of concrete
Structural settlement
It prevents cracking, leakage, and structural damage while maintaining load transfer capability.
Applications
Rubber expansion joints are widely used in:
Highway bridges
Railway bridges
Elevated roads & flyovers
Parking structures
Industrial buildings
Concrete floors and decks
Bridge expansion joints are designed to allow continuous traffic between structures while accommodating movement, shrinkage, and temperature variations in reinforced and prestressed concrete, composites, and steel structures. They stop the bridge from bending into place under extreme conditions, and also allow sufficient vertical movement to allow bearing replacement without the need to dismantle the bridge expansion joint.
