100 drilling workshops

Our technicians and our 100 drilling teams are mobilised every day out in the field to serve your projects.

Hydraulic units (light and heavy)
Pneumatic units
Mixed hydraulic and penetration testing units
DCP units
Heavy duty SCP unit
Equipment for work in cramped or difficult-to-access sites

This equipment, which ranges from 15 HP to 175 HP is used for investigations at depths of between 5 and 200 metres.

Our unit dedicated to complex investigations can either conduct direct operations or back up local teams for interventions on cramped sites, or requiring a pontoon for access or helicopter transport.

In-situ investigations

Sampling and reconnaissance surveys: core drilling, destructive testing, auger, mechanical excavator, clamshell bucket
Mechanical testing: standard pressuremeter and up to 13 MPa, rock dilatometer, static and dynamic cone penetrometer, piezocone, phicometer, SPT, scissometer
Hydrological testing Nasberg, Lefranc, USBR, Lugeon tests, pumping tests, double ring infiltrometer, very low permeability
Borehole logging: recording of drilling parameters, gamma ray logging, borehole deviation
Instrumentation: piezometer, inclinometer, settlement gauge, crack meter, extensometer, strain gauges
Road construction tests, in conjunction with our Earthworks teams: nuclear density gauge, plate bearing tests, sand patch test, PDG 1000 penetrodensitograph, Benkelman beam deflection measurements
Soil pollution tests, in conjunction with our Environment teams

Our technicians and drilling teams also carry out investigations in connection with the ELAN housing law in France, working closely with our myGéo by Fondasol teams.

Ensuring the safety of our teams' interventions

To ensure safety on our jobsites, our teams:

are responsible for submitting the DICT (Declaration of intention to commence work).
draw up clear site layout plans,
are AIPR-accredited (Authorisation to work in the vicinity of utilities)

We ask our partners specialized in Underground infrastructure detection to make drilling points safe whenever necessary.
