Polypipe Ridgistorm XL
Case study collection
Polypipe has been manufacturing and supplying Ridgistorm XL for over 10 years from its manufacturing site based in Loughborough. This large diameter pipe system enables value engineering solutions to be designed into each customer project by optimising the stiffness class of the pipework to suit the installation conditions and flexibility of design to minimise cost of fittings and chambers wherever possible.
Polypipe utilises technology from Krah Germany to produce the Ridgistorm XL product range. This technology is used worldwide in the manufacture and supply of large diameter polymer pipes.
The below illustrated case studies describe impressively the possibilities and advantages of large diameter plastic pipe solutions for a modern and sustainable water management:
Dairy processor to capture excess surface water
Over 250 metres of Polypipe’s popular Ridgistorm-XL has been installed for the expansion of an established dairy processor that has been in operation since 1938. As part of a large-scale renovation to increase yard space, Cotteswold Dairy has seen Polypipe’s thermoplastic Ridgistorm-XL solution utilised to capture and attenuate excess surface water and potential milk leakages. The complete system included 10 fabricated fittings, including 90° bends and double T sections to aid water discharge at a consistent rate in to an existing water course. The spigot design of Polypipe’s system and fittings made pipe alignment easy and fully compatible with the electro-fusion jointing method. This in turn led to a more efficient and quicker installation process.
Innovative drainage solution for £8m Darlington development
Polypipe has delivered a tailored drainage and attenuation solution for the £8 million Haughton Road residential development in Darlington. The development will include 73 new rental homes and will incorporate the site’s historic engine shed, built in 1844. The original specification for the drainage and attenuation solution included a concrete system, however due to their strong existing relationship with Polypipe, Hewitson Limited asked the manufacturer to suggest an alternative option. Polypipe tailored a solution to meet the specific requirements of Northumbrian Water. Polypipe demonstrated that its ability to provide Ridgistorm-XL pipework in bespoke pipe lengths and stiffness classifications made it one of the most adaptable large diameter piping systems in the UK, and in this instance the ideal system to meet the project’s needs.Polypipe’s Ridgistorm-XL is robust, reliable and long lasting, as well as being up to 94% lighter in weight than concrete.
New attenuation systems reduced on-site installation time at Wynyard Park
Close to the A19, north of Teesside, Wynyard Park is an exclusive community of new housing and amenities located within the historic grounds of Wynyard country estate. The original attenuation specification for the site included a box culvert design, however Polypipe was able to provide a more cost-efficient, site-specific solution that reduced installation time and material wastage. Polypipe worked closely with the project’s contractor and consultant engineer to deliver an intelligently engineered solution using its Ridgistorm-XL large diameter plastic pipe system, pre-fabricated C sections, and twin leg runs.
Polypipe’s Ridgistorm-XL specified for multimillion pound Hull residential project
Polypipe has provided a complete water conveyance and attenuation solution for a new Keepmoat Regeneration residential development in Hull.The engineered system design gained full Section 104 approval for the adoption of surface water run-off into their watercourse, and Section 38 approval for the installation of the system on the development site.The final design incorporated over 231m of Polypipe’s 1,200mm Ridgistorm-XL large diameter plastic pipework. The adaptability of the thermoplastic system meant that the Polypipe pre-fabrication team could manufacture the pipework in a stiffness class tailored to the specific ground conditions at the location, without sacrificing overall strength and resilience.
