subsurface investigation

Subsurface investigation involves examining the soil, rock, and underground conditions beneath a site to gather critical information for construction or engineering projects. This process typically includes collecting soil samples, testing their properties, and using techniques like drilling and geophysical surveys to understand the underground layers. The goal is to identify potential issues such as unstable soil or water presence, ensuring the foundation design is safe and suitable. By understanding what lies beneath the surface, engineers can plan construction projects more effectively, reducing risks and costly surprises during construction.
