Construction company Keil & Purkl Tiefbau GmbH has been a satisfied user of HÜDIG aggregates for more than 10 years.

The company was mandated to reroute a sewage canal with nominal size DN 1800.

The face sides of the excavation pit made of sheet piles were frozen by means of an ice building technique to prevent that the groundwater enters the excavation pit through the annular of the old canal.

Two HÜDIG vacuum units of type HC 488/25 were used for the dewatering of the pipe route.

Furthermore, two HÜDIG sewage vacuum units were selected for rerouting the wastewater, and finally a HÜDIG generator type STEP 60 KOMPAKT for protection against power failure. Additionally 400 m quick coupling pipe DN 159 and 200 m quick coupling pipe DN 250 have been provided to company Keil & Purkl.

The managing director Mr. Purkl confirmed a simple and trouble-free installation as well as a smooth and very low-maintenance operation of the HÜDIG aggregates!
