Difficult ground conditions called for a specialist solution when new PE pipes for potable water services had to be installed underneath two, 10-metre road crossings in the grounds of the UK’s ultimate music festival at Worthy Farm.
Brisbane is growing rapidly, with around 2.5 million people living across the city and commuting to work, university or school. To reduce congestion and CO2 emissions, the city is launching the Brisbane Metro project. An all-electric fleet of vehicles that runs 24 hours a day, without a timetable to connect the suburbs and the city centre.
To be better prepared for extreme weather events like heavy rainfall, the entire drainage system for the A7 motorway near Ulm-Elchingen in Germany was rebuilt. A section that ran underneath the motorway could only be installed using trenchless technology.
In the town of Pont-à-Mousson on the Moselle in France, the district heating network in place since 2016 was to be extended by a further 10 kilometres on the other side of the river, which meant that the river had to be crossed.
The Volkspark in Springe is a green oasis and an important recreational area for the town's residents. A more than 30-year-old combined sewer running underneath was so badly damaged by broken glass, cracks and root ingrowth that sewage was leaking out.
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.
Damaged oil tanks pose an increased environmental risk. Many homeowners are now converting their damaged heating systems to gas.
HDD record with the GRUNDODRILL 15 XP: What at first glance seemed less spectacular to the layman was a top performance for planner, executor and machine.
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.
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.
In the middle of Zurich, on Uetlibergstrasse, a section had to be connected to the sewer network using trenchless construction methods as part of a new sewer construction project. Along the route in the middle of the roadway and under tramway tracks, several power blocks, an existing sewer and a gas pipeline had to be crossed underneath.
Budleigh Salterton is located on the English Jurassic Coast: a picturesque UNESCO World Heritage Site famous for its extraordinary rocks, fossils and landforms. and a year-round tourist destination. When a 100 year old rainwater/sewage pipe needed to be replaced, a GRUNDORAM Goliath played a key role in its success.
