We produce micropiles and ground anchors with machines that are mostly equipped with hydraulic rotary percussion drill devices (the top hammer). Rotary percussion drilling is the best way to breach backfill, old foundations, boulders, sand- and limestone. We use rotary drilling devices with sand and clay surfaces. In complex conditions, we can enhance the effectiveness of rotary drilling with the down-the-hole hammer (DTH).
We use self-propelled drilling machines with adjustable mast height and separate hydraulic power station inside buildings and in cellars. We use hand held drills in particulaly narrow and low conditions. In outside conditions, we use drilling machines on belts with the mast height of 5,0 – 9,5 m and weighing 4,5 – 12 t.
