The GRUNDOMAT soil displacement hammer is ideal for the quick and gentle construction of trenchless house connections. In the Bolivian city of Cochabamba it contributed to the improvement of the drinking water supply, which is characterised by water scarcity and a dilapidated conduits. The impact mole was used to build around 1,000 new house connections as part of the inner-city drinking water network rehabilitation.
Installing pipelines in the Eastern Alps to use natural spring water from the Glingabrunnen spring - that was the enormous and demanding challenge in the Brandnertal valley: but with foresight, sure instinct and the steerable HDD drilling rig GRUNDODRILL 18ACS with rock drilling equipment, the installation succeeded without any problems and above all: trenchless.
How do you stop water loss through leaks in old pipe systems without major environmental impacts and restrictions? The answer: with trenchless technology, or more precisely the pipe bursting method.
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.
The GRUNDOPIT PS60 made it possible in the spa town of Cochem on the Moselle river to do what would have been unthinkable using conventional methods - install a new water pipeline through a densely built-up steep slope, in the shortest possible time.
Installing new house connections for green electricity under a busy street in the historic town centre of Landsberg am Lech - that was the task ahead. In this case, the medieval city centre only allowed one solution and direction: trenchless under the street.
In order to renew a particularly badly damaged water pipeline in the Moroccan capital Rabat, trenchless construction proved to be the only alternative. For NODIG technology, the work in the historic Takadoum district did not present an insurmountable challenge.
Probably the most northerly deployment of a HDD drilling rig took place high up in the north of Spitsbergen: The numerous locally based, internationally networked research stations need the fibre optic cable expansion for more bandwidth.
Almost half of the northern German island of Sylt is under nature conservation. Replacing the above-ground and therefore vulnerable, old overhead lines with underground cables without risking major impacts on the sensitive local ecosystem was therefore a challenging task.
