DRILLING AND EXCAVATION
Brief Introduction
We are capable to offer a wide range of rotary drilling works to form holes with diameters ranged from 76mm to 168mm by both coring and wireline drilling.
Excavation of trial pit, trial trench, slope stripping and inspection pit are widely used to obtain very detailed information on strength, stratification, pre-existing shear surfaces, and discontinuities in soil and rock at shallow depth.
