Soil investigation & Geotechnical

Suncon Engineers is one of the leading geotechnical companies in Pune, Maharashtra, India. We have technologically advanced soil testing laboratory in Pune, Maharashtra. We also provide geotech services in Nagpur, Mumbai & other parts of Maharashtra. We follow below steps for soil investigation to ensure accurate & reliable test results.

Field Work:

Drilling and sampling in soil & rock is carried out using rotary drilling rig. Borehole in soil is advanced using rotary drilling method, while NX size core barrel is used to drill in rock, Water is circulated to cool the drilling bit. Ground water table is recorded after 24 hours of completion of drilling. On completion of drilling, soil samples are packed in plastic containers with proper identification tags. Rock cores are numbered and kept in core boxes.

Field Tests & collection of Soil Samples: Standard Penetration Test (SPT) & Collection of Undisturbed Samples (UDS), Preparation of Bore-logs.

Laboratory Testing:

On completion of drilling samples are sent to the soil testing laboratory for further testing. Samples are classified in the geotechnical laboratory and representative samples are selected for testing. Following tests would be performed.

          • Dry Density
         • Soaked unconfined Compression Test
         • Percentage absorption and porosity
         • Mechanical analysis
         • Atterberg limits
         • Differential free swell
         • Proctor Density Test.
         • CBR Test.
         • Direct Shear Test.
         • Triaxle Tests.

After getting the laboratory soil test report & bore-logs, the recommendation report is prepared by geotechnical expert, which would be helpful to decide the type of foundation on the basis of safe bearing capacity.
