Brief History

Cavity wall construction has existed since the early 19th century and became the norm from the late 1800s to the present day.

Principal advantages of cavity construction are:

  • Thermal insulation
  • Sound insulation 
  • To prevent the ingress of moisture from outside
  • To give structural stability

Problems of Corrosion

Older types of metal tie may have no protective coating or they may have a bitumen or light zinc coating. Either way these ties are susceptible to corrosion in the presence of moisture and oxygen.

The extent and rate of corrosion will depend upon a number of factors including:

  • Exposure to prevailing weather
  • Type of mortar e.g. corrosive black ash mortar, weak and porous lime sand mortars
  • Condition of pointing
  • Poor design & construction e.g. blocked cavities, lack of DPCs
  • Environmental factors e.g. coastal locations
