At SEYFANI you can find drainage pipes of the company POLIECO with ring stiffness SN4 and SN8.

These are double-wall structured tubes that are symmetrically perforated. Their outer wall is wavy to facilitate their placement following the morphology of the ground and their inner smooth to achieve the optimal speed of water runoff.

Their exact field of application is subsoil drainage in all types of residential buildings (perimeter drainage), pitches and surrounding areas, industrial and commercial applications, photovoltaic parks, agricultural applications, landfills, and road networks.

They are available in coils with cross-sections from DN 90 – 200 mm and in straight bars of 6m with cross-sections from DN 160 – 1000 mm
