Concrete Deposits in Pipes

December 2017

Concrete deposits in pipes and sewers are always especially challenging. Using cutters for removing concrete deposits proved to be rather a waste of time and money and did not show any visible success.

Mostly, it only resulted in damaged pipes and sewers. The time has come for a new solution - tailored to these very special requirements: The Impact Hammer has been sucessfully used in a variety of pipe diameters from 150 mm upwards.

It managed to efficiently remove concrete and other hard deposits - without any damage to the pipe: e.g. a 200 mm pipe blocked with concrete underneath a motorway or a 700 mm pipe 80 percent full of concrete. One of the most vital requirements is fixing the Impact Hammer in the pipe. The integrated and patented rubber pad ensures secure fixing of the Impact Hammer as well as precise and continuous working. The Impact Hammer is equipped with exchangeable tools and can thus be optimally adjusted to different types of deposits and degrees of hardness.

Another feature, which we have really come to appreciate during various assignments, is the integrated camera with recording function. It visually supports the working process enabling the operator to work very accurate without damaging the pipe. The recording function helps documenting the work process to make it available for follow-up reviews and inspections. In this way it is possible to detect and proof damages that already existed before the start of works and to notify the customer accordingly. The Impact Hammer is also available for rent.
