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
