Ports, Airports & Harbours

With their large loadings and big impermeable expanses, airports, seaports and harbours pose very specialised water management and drainage challenges.


Our Ridgidrain and Ridgistorm-XL thermoplastic, structured walled, surface water drainage pipes, from 100-3000mm diameter, are increasingly preferred because they combine high quality and outstanding performance with lighter weight for ease of installation. They are robust, reliable and long lasting with a design life in excess of 60 and 100 years respectively.


Ridgistorm-XL is one of the most adaptable large diameter pipe systems in the UK. By analysing site conditions and installation parameters, the system can be engineered to exact stiffness classifications so that it meets the required loading specification for a project without being over or under specified.



  • Ridgidrain

    The very first twinwall surface water drainage system in the UK with Highways Authority Product Approval Scheme (HAPAS) status (up to 600mm), Ridgidrain is used for non-pressurised surface and sub-surface drainage applications.

  • Ridgistorm-XL

    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.
