Introduction to Movement Joints

Introduction to Movement Joints

A Movement Joint is simply ‘GAP’ in a structure or structural element to separate and accommodate movement.

The different types and sources of joint movement to be considered in buildings and civil engineering structures can include:

  • Thermal movement
  • Static loading
  • Dynamic loading, including vibration
  • Wind-sway
  • Subsidence
  • Shear forces
  • Seismic events

It is usually the case that Movement Joint Seals need to be able to accommodate a combination of movement types and directions , and in addition movement joint systems often need to provide a variety of other performance requirements that may include:

  • Watertightness
  • Fire Resistant
  • Thermal Insulation
  • Acoustic Insulation
  • Impact & Abrasion Resistance (Traffic etc.)
  • UV Light Resistance
  • Chemical Resistance
