Geotechnical Investigations

The necessity of Geotechnical Investigations

  • To identify the nature of each stratum and engineering properties of the soil, that may affect the design and mode of construction of the proposed structure and foundation.
  • To identify the water table which may create hindrance during the construction phase.
  • To locate the groundwater level and possible corrosive effect of soil and water on foundation material.
  • To ensure the safety of surrounding existing structures.
  • To achieve a safe and economical design of foundations and temporary works.
  • To access the general suitability of the site.

Services offered:

  • Reviewing soil reports
  • Remedial measures for problematic soils
  • Field Tests
  • Lab Tests

IBIPL carries out geotechnical investigations strictly confirming to Indian Standards.

Field Tests

➥ Drilling soil samples in all types of strata.

➥ Obtaining Disturbed Samples ( DS ) and Undisturbed Samples ( UDS )

➥ Standard Penetration Test ( SPT )

➥ K – value Test for Modulus of Subgrade Reaction

➥ Vane Shear Test for in-situ shear strength

Pumping in and Pumping out tests for in-situ permeability of the soil.

Lab Tests

Soil Classification: Grain size distribution using sieve analysis and hydrometer.

Physical Properties: Atterberg Limits, Specific Gravity, pH, Relative Density.

Engineering Properties:

    • Permeability Tests using Constant Head and Falling Head
    • Shear strength: Direct Shear Test, Triaxial Test, Unconfined Compressive Strength Test
    • Compressibility: odometer Test
