Trough construction
We construct troughs – customised to your needs
Are you looking for reliable, robust troughs for use in wastewater technology? We supply customised steel troughs and concrete troughs that are precisely tailored to your requirements – whether in the municipal sector or in industrial plants.
Our troughs are designed for high loads and can be equipped with modern wear protection on request – for a significantly longer service life and minimised maintenance.
These are your options:
- Partially or completely hard-faced with REHART-Verbundpanzerplatte (RVP)
- nanoseal coating
- Stainless steel version
- Wear-resistant special steel
We construct four different trough models for which all wear protection options are available:
- CU – compact U trough
- BS – hybrid trough
- CR – compact tube trough
- SH – Steel trough for casting
Also equipped for hydropower plants
Are you planning to build or expand a hydropower plant? We also offer suitable trough solutions that are customised to your requirements. Discover more in the section hydropower.

Trough refurbishment
We refurbish troughs – regain efficiency, reduce operating costs
Have you noticed that your auger is conveying less than before? Is the trough showing visible wear?
Then it’s time for a professional trough refurbishment. Because: A worn combination of screw and trough costs you money – through reduced conveying capacity, higher energy losses and unnecessary operating costs.
We will restore your screw trough to its original dimensions – precisely and reliably.
Why it’s worth refurbishing your trough:
- Less gap – more capacity: An enlarged gap between the screw and trough significantly reduces the conveying capacity. We restore the optimum gap dimensions through refurbishment.
- Increase efficiency: Less return flow means less energy consumption – your system works economically again.
- Reduce costs: Avoid permanent losses due to inefficient operation.
- Longer service life: Refurbishment protects against further wear and tear and significantly extends the service life of your system.
