Sizewell B, Suffolk


Sizewell B, Suffolk

The Site

Sizewell B Nuclear Power Station located on the East Anglia Coast was built between 1988 & 1995. It is capable of supplying over 2.5m homes, equivalent to the domestic needs of the counties of Suffolk & Norfolk. Around 1,000 people are employed at the station and the extended secure entrance needed to incorporate a permeable paved solution.

The Challenge

The project consultants Parsons Brinkerhoff were concerned about controlled rainwater runoff.

The Solution

SuDSFLOW resolved these issues with their innovative paving spacer and following the consultation phase they were incorporated into the design specification. SuDSFLOW spacers provide an exact 10mm joint width between the paving flags thereby allowing any modular paving to be incorporated into a permeable paving system.
