Who we are

Terrendis is a subsidiary of the Elydan group, the French leader in the manufacture of polyethylene and polypropylene pipes and channels.

What we do

Terrendis is entirely dedicated to the manufacturing and marketing of a complete range of hyper flexible pre-insulated pipes and accessories, primarily used for the transport of heating water, sanitary hot water, cold potable water, cooling and waste water or other fluids in underground networks.

Heating solutions

The heating range consists of a range of hyper flexible pre-insulated single, double and quadruple pipes. The medium pipes are made from PEX-a with an orange (flow line) or blue (return line) coloured oxygen-diffusion barrier.


The range of hyper flexible pre-insulated sanitary pipes has been designed to optimize the distribution of domestic hot water and potable water in public networks and in domestic applications.


The cool range of hyper flexible pre-insulated pipes can be used for both drinking water supply networks and air conditioning networks.


The highly flexible pre-insulated pipes are ideal for renewable energy applications such as geothermal heat pumps, wood and pellet boilers, biomass and biogas.
