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.
- Reviewing soil reports
- Remedial measures for problematic soils
- Field Tests
- Lab Tests
IBIPL carries out geotechnical investigations strictly confirming to Indian Standards.
➥ 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.
➥ 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
