Boreholes

If you are building a house, production facility or any public building, you will never manage without water. If it is not possible to connect to the central water supply system, it is wise to drill a borehole in order to obtain drinking water from deeper soil layers, where water is always available in sufficient quantity, is cleaner and is also protected from surface bacteriological contamination.

Recent hot summers have reduced the available water level in surface soil, wells and driven points, so almost every private homeowner chooses to drill a borehole to obtain relatively clean water. An artesian borehole can be drilled within a few days.

Factors determining borehole depth:

1. The geological structure at the specific site, i.e. at what depth quality water will be found
2. How much water will be needed

The advantage of a borehole is cleaner water compared to water obtained from upper soil layers, as it is isolated from bacteriological contamination. The water obtained from a borehole is located between water-impermeable layers. To construct an artesian borehole, drilling work is carried out until the water-bearing layer is reached, so that a borehole filter can be placed in it.

For equipping boreholes we use products from the leading European manufacturer "STUEWA" (Germany). Special thick-walled plastic, stainless steel or steel pipes, a special filter – a perforated pipe with or without a nylon filter fabric sleeve, special quartz stones used to surround the filter section of the borehole; a concrete layer is formed around the inserted pipe so that surface waters do not reach the water extraction layer.

For drilling we use "STUEWA" Wetronit mixture, for removing drilled material from the borehole and for hardening the walls.

The cost of drilling a borehole depends on the geographic location of the borehole, its depth, and the materials used. The approximate cost of a 40m borehole is from 2400-4000EUR (1m – 60-100EUR). The cost does not include the borehole pump (200-1500EUR), laying the pipeline to the building (100-500EUR), or pump connection (100-500EUR). Price + VAT

The company also installs vertical geothermal probes. The geothermal probe is installed in the drilled borehole, usually at a depth of 50-150m. After installing the probe, the borehole is filled with special THERMOCEM concrete, which ensures significantly better energy extraction from the ground. The cost of installing a vertical probe, including the geothermal probe itself (GEO FF PRO+, HDPE100 RC / PN 12.5), is 40-55EUR/m. Price + VAT.

For drilling we use equipment from the Italian company Massenza. We can currently offer boreholes up to 150m deep. We use the direct circulation method and the down-the-hole compressed air drilling method (DTH).

COMMODUS also handles borehole documentation (obtaining licences, preparing the borehole passport) and chemical/bacterial analysis of the obtained water, as well as delivery and installation of water filters.
