The GRUNDODRILL 18ACS "All Condition System" is a unique drilling rig in its performance class that works efficiently in both mixed soils and hard rock - with significantly lower operating costs and construction times compared to comparable drilling systems.
Proven and successful in trenchless pipe installation for more than five decades - for house connections and short undercrossings: The GRUNDOMAT soil displacement hammers.
With the powerful GRUNDOBURST systems, damaged pipes up to ND 1,200 can be replaced in the existing route using static pulling force. The versatile pulling rigs can also be used for other forms of pipe rehabilitation and repair.
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.
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.
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.
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.
