Switching to gas together: Gas connections after the Danube flood disaster

Damaged oil tanks pose an increased environmental risk. Many homeowners are now converting their damaged heating systems to gas. With technologies such as the GRUNDOMAT soil displacement hammer or the guided GRUNDOPIT keyhole technology, several connections to the transport lines can be made easily, safely and cleanly. Without an installation pit, tarmac work or holes in the house wall.

With its minimally invasive use, trenchless construction is particularly efficient and resource-saving in its implementation; neither roads nor pavements need to be torn up. Thanks to the keyhole technique, the trenchless construction method causes little surface damage or subsequent costs when laying the house connections.

Over hills and dales: New drinking water pipeline in the Swiss mountains

Narrow mountain paths, rocky ground at 2,400 m above sea level on Muottas Muragl: An old drinking water pipeline for the hotel on the summit had to be renewed, and the impassable terrain in the Engadine presented a very special challenge. For the work in the Swiss mountains, only a trenchless solution came into question: The dynamic pipe bursting method with GRUNDOCRACK.
