  • Test Pit Excavation

    Therefore, we often employ mechanical excavating equipment to conduct subsurface explorations in the form of open test pit excavations. Excavation equipment is fairly commonplace (even in more remote areas), relatively inexpensive to operate, and tracked excavators (with skilled operators) can negotiate almost any type of terrain.
