Core Material Testing Services LLP

Geotechnical investigation services involve the assessment of subsurface conditions to determine the physical and engineering properties of soil, rock, and groundwater. These investigations are crucial for infrastructure projects such as buildings, bridges, roads, dams, and other civil engineering structures.

1. Site Reconnaissance

   • Preliminary assessment of the site

   • Review of geological maps and historical data

   • Identification of potential geohazards (e.g., landslides, liquefaction, or subsidence)

2. Soil and Rock Sampling

   • Borehole drilling to extract soil and rock samples

   • Test pits and trenching for shallow subsurface evaluation

   • Standard Penetration Tests (SPT) and Cone Penetration Tests (CPT) for in-situ assessment

3. Laboratory Testing

   • Grain size distribution analysis

   • Atterberg limits tests (plasticity index, liquid limit, and plastic limit)

   • Moisture content, density, and compaction tests

   • Shear strength, permeability, and consolidation tests

4. Geophysical Surveys

   • Seismic refraction and resistivity tests

   • Ground Penetrating Radar (GPR) surveys

   • Electrical resistivity and magnetic surveys

5. Groundwater Assessment

   • Measurement of water table levels

   • Permeability tests for drainage design

   • Chemical analysis of groundwater for corrosion potential
