TECLAB offers geophysical investigations using Electrical Resistivity Tomography (ERT). ERT is used to measure the apparent resistivity of soils and rock as a function of depth or position using vertical electrical soundings. These ERT techniques together with the boreholes are used for vertical resistivity profiling.

TECLAB carries out seismic refraction tests to determine the depth to bedrock and asses rippability. In addition to the seismic down hole and crosshole techniques, TECLAB carries out the surface seismic surveys which include: multichannel analysis of surface waves (MASW), spectral analysis of surface waves (SASW) and continous surface wave (CSW) technique to determine the shear wave velocity (Vs) which is required in computation of the small strain stiffness(Gmax) used in prediction of ground settlement and deformation.

TECLAB also conducts 2D & 3D seismic surveys using both dynamite and vibroseis as energy sources.
