Conduits in water-protected zones

The combination of twin-tube conduits and ROMOLD double-walled shafts allows soil-water pipework to be constructed through water-protected zones. No other system offers conduits as tightly sealed, including shaft. The twin chamber system in the shaft ensures leakage monitoring.


Insulated conduits

For pipework that needs to be protected against cold and heat, pre-fabricated insulated conduits can be used. These are especially popular for the transport of waste water in conduits on bridges and retaining walls, or if buried where there is a risk of frost.

The space around the connection is filled with foam on-site.


The protective pipe for fluids is made of JANOlen bianco sewage pipes. The space in between is filled with a CFC-free PUR foam.

Special insulated shapes, e.g. sag pipes, can be prefabricated. If necessary, concomitant heating can be integrated.



Special designs

Jansen has well-equipped manufacturing facilities. Special designs for a huge variety of supply and disposal applications can be prefabricated, such as:


When using these Jansen specialities, we recommend that you consult our technical advisors, both in-house and in the field, early and without any obligation at the planning stage.
