Expansion Joints

Expansion Joints

An expansion joint is a device used to allow for the heat-induced expansion and reduction that takes place in various states of weather. They are designed to:

  • Absorb heat-induced expansion and contraction of construction materials
  • Absorb vibration
  • Hold parts together
  • Allow movement due to ground settlement or earthquakes
