| A revolution in drainage technology |

The Polybed drainage system comprises a geosynthetic aggregate manufactured from recycled expanded polystyrene. This surrounds a 3m length of standard perforated pipe and is kept in place with netting clamped to both ends of the pipe. The whole structure is then encased in a non-woven geotextile for enhanced filtration and reduces the risk of long term clogging. The sections of Polybed are joined by proprietary couplers.
To install, just dig the trench, join and lay the Polybed sections in place and backfill. There are no costly aggregates and time spent in the trench is reduced or even eliminated. Polybed is extremely lightweight and is four times faster to install than a traditional system. Typically it can be installed by just one operative with minimum plant.
With 35% more surface area than natural aggregates, Polybed is an ideal SUDS (sustainable urban drainage systems) solution.
