Cracking of masonry buildings is a common issue in Australia. The causes can be numerous and include the following:

• Corrosion of lintels or embedded steelwork or decay of embedded timber within walls;
• Tree root interference;
• Reactive Clay soil activity in the vicinity of foundations often influenced by soil type, the ability of water to reach underground clay beneath a structure, and the effect of trees;
• Consolidation of poorly compacted soils when loaded with the weight of a building;
• Vibration causing consolidation of soils
• Subsidence due to underground tunneling;
• Drainage problems which can lead to the softening of the ground below the footings due to saturation by subsurface flow;
• Earthquake or wind loads;
• Deterioration of materials.

Sydney Engineers are regularly commissioned to determine the probable cause of cracking and advise on action required.
