Our expertise resides in projects using geofluids in heavy construction and underground geotechnical fields. If your search
engine brought you here and your interest is in the coal slurry pipeline transport business, try another door! But if you are
in the pipeline construction business, look on, you may find some good ideas out of this site.
Our experience resides with construction projects where the wet method of excavation is used:
Quality undisturbed soil sampling
Tunnel access shafts
Horizontal recovery drains
Slurry shield tunneling machines
Self-hardening slurry cutoff walls
Pervious trenches for extraction, injection or venting

It still may be surprising to some that a 9 foot diameter hole in saturated soil can be taken down to
over 200 feet with no other support than an appropriate drilling fluid. At least most of the times, but underground work
is always full of surprises. A sound technical formation on the part of field supervisory personnel is essential to the
success of excavations under slurry support; as the working fluid is evolving constantly as the excavation progresses,
a good understanding of the physical and chemical processes at work is essential. Quality control and feedback of field
observations are integral tools for the man directly in charge of the excavation. Here as everywhere, the Observation
Method is a valuable discipline for good work. As in many other areas however, education and training may be lacking in
the real world, and allowances have to be made accordingly.
