Under tightest cramped conditions the GEO-BOHRTECHNIK GmbH drilled by carriage.
Originally designed for avalanche construction, we made holes up to diameter of 178mm at 2m with the hand-portable carriage. Drilling points which are not accessible by crawler rigs, because of stairs, elevators and so on, can be reached. The holes are used for ground surveying, groundwater monitoring wells or even for micropile foundations.
