A Soil Investigation Service (also known as Geotechnical Investigation or Subsurface Investigation) is a specialized engineering service conducted to assess the physical and engineering properties of soil and rock beneath a proposed construction site. This information is critical for the safe and cost-effective design of foundations, earthworks, and other civil engineering structures.

• Determine soil bearing capacity – for foundation design.

• Identify soil type and stratification – clay, silt, sand, rock, etc.

• Assess groundwater conditions – water table level, flow, etc.

• Evaluate potential settlement – immediate and long-term.

• Check for soil contaminants – in industrial or brownfield sites.

• Identify geohazards – such as landslides, liquefaction, or sinkholes.

• Reviewing maps, satellite images, previous reports.

• Visual inspection of the area.

• Borehole Drilling – collect soil samples at various depths.

• Standard Penetration Test (SPT) – determine soil resistance.

• Cone Penetration Test (CPT) – continuous soil profiling.

• Trial Pits – for shallow structures.

• Groundwater Monitoring – using piezometers or standpipes.

• Grain size analysis

• Atterberg limits (plasticity)

• Shear strength

• Compaction (Proctor test)

• Consolidation

• Permeability
