Dam Safety Investigations
Al Ustaz, in collaboration with PARSAN Geophysical & Geodetic Services, specializes in assessing the internal condition of dams using advanced geophysical techniques such as SRT, ERT, ReMi, streaming potential, and seismic tomography. With over 40 successful investigations across India, including World Bank–funded projects in Kerala, Al Ustaz–PARSAN provides reliable data to support cost-effective repair and rehabilitation of critical dam structures.
Runway Inspection
Al Ustaz and PARSAN apply geophysical techniques to evaluate airport runways for de-lamination, subsidence, and subsurface voids—offering faster and more accurate results than conventional invasive methods. A recent project at Delhi International Airport demonstrated the efficiency and reliability of this approach in runway condition assessment.
Condition Assessment of Caverns and Tunnels
Al Ustaz and PARSAN Geophysical & Geodetic Services utilize Electrical Resistivity Imaging (ERI) to evaluate underground caverns and tunnels for cracks, water seepage, and structural integrity. By combining resistivity profiles from the overburden and tunnel crown, detailed subsurface data is obtained to guide precise repair actions. This proven approach has also been applied successfully to detect water presence behind coal mine walls.
Concrete Scanning
Concrete Scanning GPR has been used in a large no. of projects where conventional methods for internal condition assessment of concrete have not been effective. Using advanced GPRs and 3D imaging techniques, very thick concrete slabs have been examined for internal cracks, voids and honeycombing.
Seismic Tomography
Al Ustaz and PARSAN Geophysical & Geodetic Services employ Seismic Tomography for detailed subsurface imaging and analysis. The technique involves generating 2D and 3D P-wave velocity distributions between boreholes spaced 35–50 m apart, providing high-resolution insights into underground geological conditions. With successful investigations reaching depths of up to 225 m, this method is particularly valuable for assessing terrain stability in areas where tunnels and caverns are under construction.
