The plastic residue from our production is crushed and granulated to allow us to reuse this material. Doing this allows us to save up to 88% of energy compared to producing from prime plastic material.

PE STRONG pipes which are used for making the core of our products are certified according to the Nordic standard INSTA SBC EN 13476 and marked with Nordic Poly Mark label.  Upon passing the tests foreseen by the standard the pipes are accordingly marked and will be allowed to be installed at up to -10 °C.

The prerequisite for safe maintenance of pumping stations, tanks and chambers is a solid and robust product tank cylinder. For selection of tank cylinder with sufficient strenght we use internationally licenced software for static calculations:

SolidWorks Simulation, IngSoft EasyPipe and EasySchacht.

As a material, PE is elastic and with good wear resistance. STRONG pipes are certified according to the Nordic standard INSTA SBC EN 13476 and marked with Nordic Poly Mark label. The pipes undergo the impact and ring stiffness tests foreseen by the standard.

Under normal conditions of use, PE is chemically inert material, does not decompose, rust or corrode as the result of chemical reactions in the ground. Experience has shown that a product that is made of carefully selected raw material lasts for over 50 years.
