In STS, our expert underground utilities division utilizes cutting-edge survey technology, such as dual-frequency ground penetrating radar (GPR), to pinpoint and track underground services like sewers, gas mains, heating and water pipes, electrical cables, telecommunication lines, and traffic signaling cables.
Our underground surveys furnish comprehensive insights into subterranean conditions preceding any site excavations, drilling operations, piling activities, or borehole clearance. Employing GPR and electromagnetic equipment, we can pinpoint and map underground elements like voids, steel structures, shafts, and burial sites that may influence forthcoming construction endeavors.
