A. Geophysical Survey

With an increase in demand for integrated geophysical and geotechnical surveys for on-land construction, SGES has expanded to provide the following geophysical services:

  • MASW (Multichannel Analysis Of Surface Waves)
  • Seismic Refraction Survey
  • Seismic Cross hole Test & Downhole/Up hole Test
  • Electrical Resistivity Tomography Test
  • Ground Penetrating Radar

B. Onland and Near-shore Geotechnical Investigation

SGES has found its niche in the on-land geotechnical investigation by boring deep using hydraulic rotary drills and offers end to end geotechnical services for on-land and near-shore projects for sectors of Residential/Commercial Buildings, Dams, Thermal/Wind Power/Hydro Power Projects, Coastal works etc. A suitable marine spread namely floating pontoons and/or staging platforms will be deployed in water depths up to 5m for all coastal projects. Our team comprises of several qualified and experienced site engineers/supervisors/drill operators and technicians. We possess the following tools and capabilities to make shallow/deep soil borings as well as in-situ tests in all kinds of subsurface stratum according to BIS/ASTM Standards:
  • Mechanically/hydraulically operated rotary/wireline drilling rigs with necessary standard drilling tools.
  • Single, Double and Triple Tube Core Barrels
  • Standard Penetration Test
  • In-situ Pressure meter Test
  • Field Permeability Test
  • Compaction Control Tests
  • Field CBR Test
  • Piezometer to Monitor Pore water Pressure
  • Block Vibration Test
  • Axial, Lateral and Pull-out Test of Piles
  • Pull-out Tests on Grouted and Driven Nails
  • Design and Installation of Multiple Well-point System for Dewatering
