๐Objectives of Soil Investigation
๐ซ1. To determine the type and stratification (layers) of soil beneath the site.
๐ซ2. To find out the bearing capacity of the soil how much load it can safely support.
๐ซ3. To determine the depth of the water table (groundwater level).
๐ซ4. To detect any weak or problematic soils (e.g., expansive clay, peat).
๐ซ5. To recommend the most suitable type of foundation (e.g., raft, pad, pile).
๐ซ6. To estimate settlement and stability under loading.
