GSI company succeeded to identify and mark the position and depth of metallic and non-metallic objects using a GPR ( ground penetrating radar) systems in Giza city

GSI provides a Geophysical study as part of a landfill project in Burg El Arab City (Alexandria) to evaluate the groundwater aquifer and determine the water table , by ( VES ) vertical electrical sounding .

Introduction Geoservices and Subsurface investigation company (GSI) team of highly experienced geologists and geophysicists can cooperate together using our latest subsurface techniques to support Mining exploration field. Our services GSI can support the Mining exploration field by Remote Sensing Shallow Geophysical survey ERT GPR Shallow seismic processing and interpretation. Remote Sensing We interpret remotely sensed data

Two modes of operation are common, namely, a) depth sounding and b) pro-filing. In the depth sounding mode, all four electrodes are initially placed in the ground with a very short spacing between adjacent electrodes. A reading is taken, and then the array is reset with an incremental increase in spacing.Another reading is taken, and

Radar waves transmitted and received by a control unit operating a transducer / antenna that pulled along the ground. A time section simultaneously displayed on a chart recorder. Effective depth of penetration ranges from about one foot in moist clay to 50 feet or more in dry granular sediments and rocks, and governed by ground
