Context

Polypipe supplied a durable and cost-effective thermoplastic solution to ensure efficient water management and optimum flood resilience for the UK’s largest self-build community at Graven Hill, Oxfordshire.

The 188-hectare site provides purchasers with the chance to build their own home, with a focus on energy-efficient materials, modular construction methods, and contemporary design.

Products supplied

Following previous positive experiences with Polypipe, contractor Careys Civil Engineering recommended that the original clay and concrete design specification be changed to a more durable and cost-effective thermoplastic solution, incorporating Polysewer and Ridgisewer. The structured wall pipes offer ring stiffness and strength, while ensuring flexibility to allow for ground movement and differential settlement. They can also be manufactured to exact specifications and delivered at precise times, reducing labour time on site.

The solution included a system for foul water management using over 2,250m of Polypipe’s Polysewer and 330m of Ridgisewer structured wall pipes, along with the necessary associated bends and fittings required to fit the pipe runs.

To capture, store and control surface water run-off, over 220m of Ridgistorm-XL large diameter pipes were supplied in a stiffness class of SN2 to suit the site’s ground conditions, together with two tanks manufactured using Polystorm-R cells. Polypipe’s Polystorm-R cells have a 95% void ratio, with a load-bearing capacity of up to 61 tonnes per square metre, making them ideally suited for trafficked and loaded applications at greater depths. The two tanks will provide over 336m3 of water storage, ensuring flood resilience even in extreme weather events.

Testimonial

“We have worked on numerous projects with Polypipe and have remained impressed with their high level of customer service and the quality of their range of products. We recommended that the original specification for the Graven Hill site be changed to a thermoplastic solution, as we knew that it would be safer, easier and quicker for our groundworkers to install, while offering the robust infrastructure required for this large-scale project.”
