When it comes to surfacing, particularly for retail, residential, and regeneration projects, SuDS Compliance is an important requirement.

SuDS stands for ‘Sustainable Urban Drainage System’. SuDS compliant surfaces are porous and allow for water to drain through to the natural ground. Alternatively, SuDS compliant surfaces may feature a soak-away or swale. In these cases, water is drip-fed into drainage and sewage systems to prevent them from being overwhelmed from water run-off.

SuDS compliance became particularly important in April 2015. This is because, at this time, legislation came into effect which was designed to lessen the impact of surface water flooding in new development areas. This means that any driveway or other surface area must be SuDs compliant to lessen the strain on the national drainage network and minimise the risk of local flooding.

Why is SuDS Compliance so important?

As areas become increasingly urban and built-up, the effectiveness of the earth’s natural drainage systems is diminished. That means that water is unable to infiltrate the ground (due to concrete, for example) and runaway naturally. In areas where effective drainage isn’t built into the infrastructure, during periods heavy rain flooding is common. Not only is this devastating for homes and businesses, but it also has a terrible impact on wildlife too.

SuDs compliant surfacing helps to take away some of the strain on the national drainage network, particularly during heavy rain. For example, driveways and footpaths which are porous and SuDS compliant, allow for water to drain away as it would in nature and feedback into surrounding natural reservoirs such as lakes, streams, and rivers.

Is NatraTex SuDS compliant?

NatraTex surfacing, from NatraTex Colour to NatraTex Eco and Colour, can be made to bespoke specifications. Therefore, should a project require SuDS compliant surfacing, NatraTex asphalt surface courses can be made to the correct level of porous to meet these requirements. Furthermore, NatraTex surfacing products are very much sympathetic to the surrounding environment and bring many benefits over resin bonded or resin bound systems.

NatraTex Porous was used in a variety of applications for Marjory Kinnon School in Feltham, Middlesex. Due to limited falls on the substrate, it was a requirement that the surfacing should be porous throughout. To find out more about this project, and other NatraTex applications, take a look at our Case Studies.
