Rock Science That Serves Your Projects

With over 40 years of experience in drilling operations, our teams have acquired extensive knowledge of the different geological formations, rock types and their specific behaviour during drilling or breaking. This knowledge is invaluable during rock breaking and leveling operations, especially when precision is required. It allows us to adapt the techniques and tools used, anticipate potential difficulties and guarantee better results, in complete safety and with respect for the environment and deadlines.

Your Project Deserves LEG Precision

Our expertise in rock breaking and leveling was developed and perfected during our operations installing self-supporting pylon foundations on rock. In these installations, the required precision is vital, as a precise geodesic level must be reached with a very strict tolerance. This is why LEG has become a master in breaking, leveling and excavating rock with a very high level of precision that at times resembles goldsmithing more it does than civil engineering. This expertise, acquired and refined in the field, allows us to offer custom solutions to meet the specific needs of every project, and guarantees impeccable results and total client satisfaction.

The Right Tool Is the Guarantee of a Job Well Done

At LEG, we master cutting-edge techniques to break and level rock properly and efficiently, with a high level of precision, in complete safety and respect for the environment. We use proportional hydraulic rock-breaking hammers, rotary milling machines, honeycomb drilling and the excavation of friable rock with toothed bucket. These methods, combined with our expertise and high-performance equipment, allow us to adapt our approach to every project, and guarantee impeccable results and total client satisfaction.
