Instruction clips

Flexirohr is a product for relining of DN 100-300 mm defect gravity sewers. The method is a cost-efficient and fast way to rehabilitate old concrete sewers. By cost-efficient we mean low investment to the installing equipment. Installing can be performed with a 2-man crew and the equipment fit nicely in a van. A further advantage of the method (compared to CIPP) is that no by-pass pumping is needed during the installation.

In the video clips you can see a relining of DN 225 mm concrete sewer with Flexirohr DN 200. The videos show the process step-by-step. We offer on-site training to installing companies. Feel free to contact our sales team!
