đObjectives of Soil Investigation
đŤ1. To determine the type and stratification (layers) of soil beneath the site.
đŤ2. To find out the bearing capacity of the soil how much load it can safely support.
đŤ3. To determine the depth of the water table (groundwater level).
đŤ4. To detect any weak or problematic soils (e.g., expansive clay, peat).
đŤ5. To recommend the most suitable type of foundation (e.g., raft, pad, pile).
đŤ6. To estimate settlement and stability under loading.
