Soil Investigation

---

   Soil Investigation is required in order to determine the bearing capacity of the soil, its settlement rate and the position of the water table thus making it necessary to be done before lying any foundation. Avian Test Lab conducts major Soil Investigation test.

Following are the test which we perform for Soil :

•    Plastic Limit test
•    Proctor (Light Compaction) MDD & OMC
•    Atterberg`s Liquid Limit
•    CBR (California Bearing Ratio) Soak
•    CBR Un-Soak
•    Direct shear test (Cohesion)
•    Dry Shrinkage Test
•    Free Swell Index
•    Grain Size(75µ sieve) and Hydrometer Analysis
•     Moisture content test   Permeability Test
•     Proctor   density (Heavy compaction) MDD&OMC
•     Sand Equivalent Test
•     Specific Gravity
•     Triaxial shear test (Cohesion)
•     Consolidation Test     

      On Site :

•    Density by Core- Cutter method
•    Density by Sand Replacement Method
•    SPT Test ( Rock Area)
•    SPT Test (Soil Area)
•    Field CBR By DCP Test
•    Plate Load Test
•     Concrete Core     

   Chemical Test:

• pH Test
• Sulphate Test
• Calcium Carbonate 

  Bentonite :

•    Liquid limit test
•    Moisture Content test
•    pH test
•    Sand content test
•    Marsh cone viscosity
•    Swelling Power test
