Product Description
Rubber Seal for Aluminium WOSd Joint
Expansion joints rubber seals create a flexible transition point between adjacent concrete or cement panels, allowing the structure to expand and contract with temperature changes and move with minor seismic shifts or strong winds without damage. Expansion joints can also provide a waterproof seal between panels to prevent water and debris penetration, making them a critical component of bridges, rooftops, and parking garages.
