Ground blasting and explosives
Comprehensive 3-D localization of the hole to verify drill locations and place the charges accordingly
Transport of explosives by helicopter, here 850 kg to be detonated in a mountain area (2500 m – Pyrénées)
Installation of vibration sensors to ensure allowed thresholds are respected
Blasting to secure an old mine shaft in a high-mountain area (2500 m)
Safety Blasting
Deepening the 7-m tunnel to install a new turbine (drilled-shaft type).
CFL drilling in mine shaft to create a 20-ml deep, 3-m diameter ventilation well et de 3 m de diamètre
Preventive explosion taking into account an EDF tunnel located less than 30 ml away, and additionnally the work site spills into the Parc National des Pyrénées
Blast in tunnel under a hydroelectric power plant. After breaking up the calotte and carrying out the blast, we remove the guards of the clamshell
Controlled blasting
T23-water drilling for stone trap in EDF tunnel
Blasting for sanitation trench, we came within 0,5 m of the church wall.

Cleaning out of a very small-size tunnel.
Manual cleaning-out using a home-made cart
After separating the wastewater and rainwater networks reinforcement,
injection and drainage operations take place. Urban tunnel.
Drilling prior to draining in a small-size tunnel feeding a hydroelectric power plant. (Andorre).
Large-size tunnels or galleries
