Ridgistorm-XL Pipe System

Ridgistorm-XL is an engineered thermoplastic large diameter pipe system, in diameters 750-3000mm, for use in a wide variety of applications including surface water, foul water, combined sewers, large scale flood alleviation schemes, renewable energy and even displacement ventilation.


We also offer a range of pre-fabricated, engineered solutions which are designed to integrate seamlessly within existing drainage or water management systems, including our Ridgidrain, Ridgisewer or Ridgistorm-XL systems.

    Standards & approvals

    Ridgistorm-XL has been through extensive testing to ensure the system is WRC approved, and comes with Water Company Approval for Capital Works projects and installations under Section 104, Section 106 and Section 38 agreements

  • Ridgistorm Engineered Design Pipes

    Engineered designs

    By analysing the site conditions and installation parameters of a projects, our design engineers can create a solution with the appropriate profile strength and stiffness classifications for each project, with pipe strength at varying stiffness classes between SN1-SN8.

  • Ridgistorm Pipe Profile Designs

    Pipe profile design

    Pipe profile designs can be adapted to maximise strength and minimise the use of material within the pipeline. This improves pipeline performance and provides a fully engineered solution.

  • Ridgistorm Jointing Options

    Jointing options

    Ridgistorm-XL can be designed and manufactured to suit any jointing requirement on-site. This includes ring seals, electro-fusion welding, extrusion welding, flange connections and mechanical pipe couplings.

  • Ridgistorm Jointing Frame

    Ridgistorm-XL Jointing Frames

    The Ridgistorm-XL Jointing Frame is a multi-use tool for assisting the jointing of Ridgistorm-XL ring sealed pipes in sizes 750-1800mm. They assist with the safe jointing of pipes by providing a flat surface for on-site construction machinery to apply a central force to push against, eliminating any damage to the end of the pipes and keeping the joining pipe square to the joint. They are constructed from steel with four built in lifting points for safe handling on-site.
