Boreholes

Sondalis specialises in drilling water abstraction boreholes using a vast range of equipment, which allows drilling up to 1200 m deep.

The company uses three drilling methods: rotation by direct circulation of sludge; a rotation by inverse circulation of sludge and, finally, rotary percussion (pneumatic percussion using a DTH – down the hole hammer).

The company also has 11 different-sized equipment as well as high-technology drilling attachments, enabling it to effectively execute works in any type of geological soils.
