BUILT ON ROCK
Rock drilling is used particularly with less favourable ground conditions, such as rock, granite, asphalt, concrete, blast-furnace slag or extremely compound grounds.
Rock drilling takes place through the suctioning of the ground granulates (re-filling is possible). From 140 to 200 mm in diameter we would drive through drillings of up to 2,000 mm of depth, also with other grounds.
If necessary we concrete the rock drillings with a specialist fluid concrete (with a minimum quality of C16/20) and ram the foundations in afterwards. Through ramming in the posts, the pores of the concrete are fused and thereby provide for the necessary firmness and/or stability.
For particularly difficult ground conditions we can produce concrete shaft rings.
