In building surveying, “ageing of materials” refers to the process by which materials used in construction gradually deteriorate or change over time due to various factors such as exposure to weather, wear and tear, chemical reactions, biological activity, and other environmental influences. This ageing process can affect the structural integrity, appearance, and performance of the materials, ultimately impacting the overall condition and longevity of the building.
Building surveyors assess the ageing of materials as part of their inspection and evaluation of buildings. They examine the condition of materials such as wood, concrete, steel, brick, mortar, roofing materials, insulation, and others to determine their current state and anticipate any potential issues or maintenance needs. Understanding how materials age helps surveyors identify areas of concern, plan for repairs or replacements, and recommend appropriate maintenance strategies to preserve the structural integrity and functionality of buildings over time.
