In turn, this movement can cause cracking to the walls of the building which, without attention can quickly worsen and leave the property in a potentially unsafe condition. Cracking and deterioration of masonry can also occur as a result of the freeze/thaw cycle, corrosion of embedded steelwork, increased loading an due to inadequate or defective materials having been used.
