EMAS well drilling, Part 2 of 2

EMAS well drilling is a method for drilling small-diameter tube wells by hand, up to 100 m deep. The drilling method is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as well as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground). The usual diameter of the tube well is 37 mm.
