In Seattle, the unique combination of geological and environmental factors, including soil composition and seismic activity, underscores the necessity for frequent and thorough foundation inspections. The city's soil primarily consists of clayey materials, which are prone to expansion and contraction with changes in moisture levels, making them particularly susceptible to foundation issues. Additionally, Seattle is situated in a region known for seismic activity, which can further exacerbate existing foundation problems or lead to new ones. Given these conditions, regular inspections are essential to detect early signs of foundation settlement and sinking, allowing for timely intervention and the implementation of effective repair solutions to maintain the structural integrity of buildings in Seattle.
