We specialize in the measurement and determination of the radon index on building sites and in building interiors. We provide advice and consultation on radon issues. We propose solutions and procedures for radon protection.

We provide geological surveys for building foundations, hydrogeology, radon measurements and slab compaction tests. I assess exposed foundation joints. I investigate and determine radon index categories of foundation soils. I measure bulk radon activity in residences.

We provide cleaning and disinfection of wells, water tanks or de-acidification of sumps. We offer well repair, maintenance, and reconstruction and contract care of water resources. We provide water analysis and expert advice. Radon measurements in rooms and on plots.

I offer radon measurements in soil and rooms or water. I clean dug wells to a depth of 23m, repair hand pumps.

We measure the radon index of land for building permits and radon in finished buildings for approval purposes. We provide radon consultancy services.

The first geophysical workplace in South Bohemia (since 1985) with more than thirty-five years of experience. We carry out radon measurements on land before construction starts and control measurements of radon concentration inside buildings for the approval procedure. We provide advice on radon and radionuclide issues.

I perform radon and bedrock surveys.
