Excellent & Quality Testing

Geotechnical & Geophysical


Geotechnical investigation (Surface and Subsurface explorations) services to architects, developers, consultants and contractors. These investigations are performed to guide the consultants and the designers in designing the suitable type of the foundations or to provide general information regarding the subsurface conditions. Subsurface exploration usually involves drilling of boreholes up to the required depth and collecting samples for further laboratory tests.

Geotechnical division also provides, site supervision and field testing services during soil investigation and foundation construction.

Jacob Laboratories provides wide range of geotechnical service requirements to the construction and allied industries. These includes but not limited to the following;

Standard Penetration Tests (SPT)

  • Rock sampling using HQ, HWF, PWF techniques with rotary drilling.
  • Disturbed bulk sampling using percussion drilling.
  • Cone Penetration tests (CPT).
  • In-situ permeability Test.
  • Plate Load tests.
  • Falling Head / Rising Head /Constant head permeability Test.
  • Groundwater level monitoring.

Geophysical investigations are used to estimate the physical properties of the subsurface by measuring, analyzing, and interpreting seismic, electrical, electromagnetic, gravitational, and magnetic fields measured at the ground surface or within boreholes.

Geophysical exploration supports the soil investigation and analysis integrity which increases the safety of the construction industry due to the hidden underground geological, hydrological or unknown factors that might contribute and form a risk factor to the proposed structures on different scales.

Jacob Laboratories provides vide range of Geophysical service requirements which includes but not limited to the following;

  • Seismic: Multichannel Analysis of Surface Wave (MASW).
  • Electrical Resistivity Tomography (ERT).
  • Electromagnetic Survey.
  • Ground penetrating radar (GPR).
  • Down Hole test (PS Logging).
  • Cross hole Tomography (Seismic).
  • Cross Hole Tomography (Electrical).
  • Underground Utility Detection.
