DETECTION OF UNDERGROUND VOIDS/CAVITIES

Identifying voids as early as possible is essential for both safety reasons and project timeline maintenance. Voids can be hazardous to both the workers and the general public. And, discovering them too late can lead to project delays and also increased costs. We at GS&C Singapore employ a variety of non- intrusive geophysical approach to detect and accurately locate underground voids.
