Working alongside main contractor Buckingham Group Contracting Ltd [BCGL] and consulting engineer BWB, Polypipe CGU were able to produce an alternative infrastructure drainage system utilising Ridgistorm-XL in sizes 750mm and 1500mm for the conveyance and attenuation of stormwater at the site, in replacement of a previous design consisting of soft SuDS, which took up vital development land.
Taking advantage of the high-quality engineering fill that was readily available, the Polypipe CGU team worked closely with Buckingham Group and BWB Consulting to calculate specific structural requirements. The Ridgistorm-XL pipes were then manufactured specifically for the stiffness classification required by on-site ground conditions and loading considerations. The system also incorporated pre-fabricated RidgistormAccess Multiple Pipe Manholes, which allow for inspection access and connecting dual runs of pipe.
