Structural Cracking and Movement

Structural Cracking and Movement is where non flexible elements of a building break apart forming a crack. Cracks can open or close depending on the forces and movement that caused the cracks.

Cracking to buildings are usually caused by one of the following:-

  • Movement to the foundations of the building
  • Expansion and contraction of building elements in response to changes in temperature
  • Changes in the loads on structural elements as a result of modifications to or use of the building
  • Damage to a structural element (corrosion, impact damage, termite damage, fungal decay, etc)
  • Drying and shrinkage of timber elements
  • Compaction or settlement of structural elements over time.

The inspection include checking for these conditions in:

  • Roof Structures: Concrete roof slabs, masonry parapets and gable walls. 
  • Wall Structures: Masonry, external render & stucco, internal solid plaster, internal lath and plaster, fibre cement sheeting, rendered wall board, plaster sheet & plasterboard
  • Floor Structure: Reinforced concrete constructions
