Drilling Services - Geotechnical

Quality of soil samples is crucial in geotechnical drilling and recovery demands a high level of expertise and precision.

Data collected during drilling needs to be accurate because it influences decision making and budget considerations.

Our installation of in-situ geotechnical instruments, such as piezometers, inclinometers and extensometers ensure accuracy without wasting time.

A full range of overburden testing equipment is available with capabilities such as coring and testing on holes up to PQ size to a depth of 250 meters.

Our geotechnical applications typically include infrastructure developments such as;

• Processing plants and buildings (e.g. LNG, mine sites)
• Service roads, jetties and wharfs
• Construction and upgrade of major bridges and roads
• Construction and upgrade of water supply and tailings dams

Geotechnical drilling techniques and capabilities include:

• Marine and Jack Up Barge drilling
• Wireline diamond drilling NQ, HQ, PQ (Wireline triple tube diamond core drilling in rock)
• Mud Rotary Drilling
• Air core drilling and sampling
• Hollow flight and Solid stem Augers
