Geotechnical/ Soil Testing Services

SOIL TESTING SERVICES

GGPL provides Geotechnical services includingin-situ Geotechnical field investigations and laboratory testing. The in-house Soil Testing services laboratory caters todetermination of various geotechnical parameters as per relevant IS Codes.

GGPL also offers services for ground improvement/slope protection work. The ground improvement/ slope protection work is performed either for natural landslide or manmade vertical/ steep excavation for underground basement work, where there is no space for excavation in stabilized slope. Such services are performed using appropriate techniques like Soil/Rock Nailing, Piling, Shotcreting and Grouting.

The details of services offered are as follows:

1. Geotechnical Field Investigations/ Soil Testing Services

  • Soil boring of 65 mm to 600 mm diameter borehole
  • Rock core drillingof 65 mm to 450 mm
  • Geologging of boreholes; and trial pits
  • Subsurface sounding for soils: Dynamic method using 50mm cone without bentonite slurry, and 5mm cone with bentonite slurry
  • Static Cone penetration test (2 to 3 ton & 10 ton capacity); Standard penetration test for soils (SPT)
  • Plate load test on soils for determining bearing capacity of foundation
  • In-situ Field Permeability test – overburden material
