Finger Joints

HERCULES Finger Joints have been developed to fill the need for a heavy-duty expansion joint with large movement capacity. This type of expansion joint has been adopted as standard design for large movement expansion joints by many design authorities and government agencies worldwide because of their low & easy maintenance features.

The proven “Built-To-Last” design & performance of finger joints are internationally recognized & are being installed in thousands of projects across the world for the last many years because of its riding comfort and watertight low maintenance features.
