Analyzing the soil on a site where a building is to be built is known as residential soil testing. To make sure the foundation can sustain the weight of the home and avoid damage from soil movements, testing is necessary to ascertain the composition, strength, and load-bearing capacity of the soil. Before construction, residential soil testing is crucial for several reasons, including adherence to local building rules and standards, foundation design safety, structural safety, and cost savings. To analyze the soil, samples are taken at various depths, and their physical characteristics are examined. To determine the site classification, tests are conducted both on-site and in the laboratory. 

The site classification value is a system of categorization that is used to establish whether the soil is suitable for constructing a house and to plan the best foundation for the location.
