Overpipe™ was developed in France as an alternative to the 150 – 200mm thick concrete slabs used as an underground protection barrier over high-pressure gas pipelines. Overpipe is designed as a penetration barrier, to withstand the attack of excavators and post-hole augers.

Due to Overpipe™’s effectiveness and the cost savings generated, it is now used by major gas, power, telecom and rail utilities across the globe to protect critical buried infrastructure.

Overpipe™ is a 15mm thick, 1800mm long virgin polyethylene plate, brightly coloured with an embossed warning message. Widths vary to suit different pipe and cable diameters. Thanks to the properties of the material, colour, and performance will be unaffected by soil conditions for many decades underground – hence the 50-year warranty.

Unlike concrete, Overpipe™ is light, easily transported, can be cut to size, and is flexible and prefabricated. This allows the plates to be removed intact to enable access to the pipe or cable, then re-laid.
