CGS department with central laboratory - inorganic geochemistry, geochemistry of rocks and environment and special laboratories.

We provide complete implementation of wells.

We provide core, hydrogeological and small diameter boreholes, engineering geological and hydrogeological surveys. We provide construction supervision, evaluation of rock and soil recoverability and measurement of the deformation modulus of the subsurface. We offer soil and aggregate laboratory testing and water analysis.

We carry out surveys, risk analysis and remediation of contaminated sites and geotechnical, engineering geological and hydrogeological surveys.

Offer borehole and well cleaning throughout the country, pump service and repair, plastic manhole fabrication and seating. We provide indicative pumping tests. We provide individual consultation and service, professional services in the care of your water resources - boreholes, wells. We offer many years of experience.

We specialize in working in non-breathable and hazardous environments. We provide fire extinguisher service. We also perform well drilling, gas analysis and suction dredge cleaning. We offer controlled mains extrusion and boreholes for heat pumps. We provide professional training and consultation.

Offering water source locating, pumping tests, sampling and water analysis including survey and pollution remediation. Provision of drilling works. Arrangement of well approvals. Determination of water source protection zones. Possibility to measure flow in streams.

Offer building and maintenance of groundwater resources. We own the largest drilling park in the Czech Republic. For drilling in hard but non-cohesive rocks. We provide hydrogeological, ecological, geological and engineering geological works (water sampling, borehole inspections, etc.).

We provide engineering geological and hydrogeological surveys including surveys of landfills and contaminated sites, radon measurements, drilling and field geotechnical testing.

The pyrotechnic survey and demining is carried out by a qualified pyrotechnician. We carry out pyrotechnical surveys throughout the Czech Republic on the ground, in water, and in drained ponds. Detection of unexploded bombs is carried out by a pyrotechnician using a magnetometer. A bomb technician on site will ensure your safety.

We carry out advance and rescue archaeological excavations on sites threatened by construction activity. We present and popularise archaeology.
