Twin-walled underground burial conduit which has a corrugated exterior for additional strength, and a smooth internal bore that prevents cables from snagging.

Manufactured from lightweight HDPE (high-density polyethylene) by a twin-extrusion process. This is where two pipes are extruded simultaneously (one inside the other) and heat welded in one continuous process.

Used to convey mains electricity, data and telecommunications – the twin-walled range is coloured black and facilitates easy cable insertion.

Given the flexibility and mechanical resistance, and its high resistance to chemicals and water ingress, the underground conduit lends itself nicely to various installations, including those where an irregularity in the ground level is present
