Blétry AG

Blétry AG carries out groundwater drilling and well construction, specifically sinking the extraction and injection boreholes, core drilling through the house wall, and the excavation and piping work from the well to the house. The company also handles coordination with the cantons for the required water rights permit.

Beyond groundwater drilling for heat pumps, the company offers borehole heat exchanger drilling up to 400 meters, exploratory drilling up to 1000 meters, and concrete cutting work. The business is based in Küttigen AG and covers northwestern Switzerland. Technical questions about the suitability of the ground are checked in advance, so that permitting and execution go smoothly.
