When it’s too important to guess what’s underground, we get you the answers.

Move forward above ground with confidence and surety.

Understanding what's underground is critical if you want to protect assets, build or develop, mine, or gain awareness of seismic risks. RDCL's geologists, geophysicists and geotechnical engineers use state-of-the-art technology, including Downhole Geophysics, Surface (Seismic) Geophysics and CPT for precision site testing and evaluation.
