What Our Customers Say

'Good Service is Good Money'

„The company Umwelttechnik Strobel GmbH has expanded significantly in the past few years. We are continually taking on new employees in order to address the always growing demand of our clients with higher quality while maintaining cost effectiveness. Of course, our new employees need to be extensively trained in the machines and materials we use. Nowhere have we encountered professional support to the extent given by I.S.T. GmbH. If we need training, a call is sufficient to bring an experienced employee from I.S.T. to our door within the shortest time to teach our employees as long as necessary for them to do the work perfectly well themselves. The excellent Service and Support of I.S.T. GmbH has saved us a good deal of money in the past few years.“

Sidon Futterknecht, Umwelttechnik Strobel GmbH

'Night Shift'

„We installed 300 mm liner and, after steam curing, definitely needed to open the six connections that the installation had closed off. Upon opening the third connection, a hydraulic line in our cutter robot started to leak, halting our progress. Because it was 7pm already, there was no possibility to call a subcontractor. Via call forwarding, we reached an employee of I.S.T. GmbH. The spare part was available in their warehouse Bochum. After briefly considering the situation, the employee jumped in his car and started on his way to drive 300 km to the job site. Our employee joined him in the car and received the replacement part at around 10pm. Hence, we were able to cut out the connections in the same night. To us it was quite remarkable, that I.S.T. had so quickly decided to help us out of the situation although the replacement part cost only 120 Euros.“

Dipl.-Ing. Rolf Spannuth, Ludwig Pfeiffer Hoch- und Tiefbau GmbH & Co. KG

'One-Stop Shop'

„Many years ago, as we started out in the sewer rehabilitation industry, we often changed suppliers and used components from various companies. Again and again, problems would crop up with the reliability of suppliers and the quality of material. For the past three years, we have been obtaining our perishable materials almost exclusively from I.S.T. GmbH. Since this time, we have had no problems with delivery dates, wrong deliveries or insufficient quality. Besides, we always have a contact partner in I.S.T. if should we require application-specific advice. The comfortable telephone reception at I.S.T. is likewise a significant advantage. We have since come to realize how important constant quality, reliability of deliveries and technical support really are. In this respect, I.S.T. has always been an outstanding partner.“

Andreas Baier, Baier Rohrreinigung GmbH (Erlangen)
