Descriptiontext

Calcis is a privately-held engineering geophysics contractor and engineering geological consultancy operating from Liège, Belgium (Calcis srl, VAT BE 0501.955.204) and Strassen, Luxembourg (Calcis Luxembourg sarl, VAT LU 31583563, designated headquarters). The firm was founded by Tim NZALI, who holds qualifications in Geophysics, Hydrogeology and Engineering Geology and brings 25 years of project experience across Europe, the Middle East, Africa and the Americas spanning magmatic and metamorphic terrain, groundwater flow and contaminant transport modelling, port and coastal development (UXO detection, dredgeability, seabed investigations), and on-land site investigation.

The company's offering is organised around three integrated service lines: Geophysics, Geotechnical Consultants, and Geological Engineering. The Geophysics practice deploys a multi-technique stack — seismic (refraction, reflection, ReMi surface-wave), electrical resistivity tomography (ETR), microgravity, ground-penetrating radar (GPR), magnetometry, electromagnetic surveys, and borehole geophysics (downhole, crosshole, uphole tomography) — on the stated principle that no single technique is universally effective. The Geotechnical Consultants line provides on-site engineering supervision (borehole supervision, sampling, laboratory coordination, and field tests including CPT, pressiometer, dilatometer, SPT, vane). The Geological Engineering line integrates desk study, geophysical and geotechnical data into engineering geological models for risk assessment and operations planning. Together these services address ground-risk reduction across three primary verticals: Infrastructures & Civil Engineering (tunnels, high-speed rail, highways, airports, dams, bridges), Quarry & Mining (overburden, weathering, karstification, excavability, borehole targeting), and Environment (waste disposal site characterisation, contamination, groundwater, archaeology, UXO), with Nearshore Infrastructure listed as an additional sector.

Calcis monetises through professional services on a quote-based, project-specific pricing model, sold primarily via direct, consultative engagement with contractors, engineering firms, quarry operators, environmental consultancies and government entities. The company markets almost exclusively through its bilingual French/English website (calcis.eu), has no disclosed app, API, or technology integrations, and shows no external funding, partnerships, awards, patents, or named customers in the available data. It remains a founder-owned, sub-ten-person specialist consultancy.
