The MINROC pipe umbrella system has been used as a safe and reliable drilling system on a large number of construction sites. Since the introduction of our equipment in 2000 we have been able to build up a long reference list of projects worldwide. Special features of our system are simple handling and rapid drilling progress. It can be used both for top hammer and DTH hammer drilling processes in very different geological conditions.
