Product Description
Compression Seal Expansion Joint
  1. General Concept of expansion joint is to provide the continuity between two parts of a structure which are in relative movement because of vibration, seismic load, thermal expansion or contraction, shrinkage etc. Expansion joints are used primarily to relieve stress due to confinement of a slab. An expansion joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, or to allow movement due to ground settlement or earthquakes Expansion joints are designed to support heavy and rigorous traffic load with minimum noise and bumps so that the driving experience can be with maximum pleasure.

INSTALLATION PROCEDURE

  1. Recess shall be prepared little lowered in a pre-determined position and the edge beams shall be placed in a position that both are aligned properly.

  2. Steel structure and main reinforcement bar shall be anchored with proper welding.

  3. Alignment shall be checked for both steel structures, if required by using suitable device.

  4. Recess shall be filled with high quality of the concrete not less than M 35 grade.

  5. Kantaflex compression seal of the required length shall be inserted in between the edge beams by using the proper device, duly applying adhesive recommended by the manufacturer.
