SuDS and GeoPave Resin Bound Surfacing
SuDS* or Sustainable Drainage Systems is the name given to a number of measures aimed at reducing the amount of surface water runoff generated after precipitation. Our increasingly urban environment has been designed to remove water from surfaces quickly but this has shifted the problem from the surface to downstream into our sewers and rivers and is responsible for much of the ‘flash flooding’ we have experienced in recent years.
SuDS comprises a number of components such as preventative measures to prevent leaks, the creation of green roofs, filter drains, ponds and wetlands and others. One of the important components is the provision of pervious surfaces which allow rainwater to drain through them into the underlying construction or soil.
Schedule 3 to the Flood and Water Management Act 2010 requires construction work with drainage implications to have its drainage systems for managing surface runoff (including rainwater, snow and other precipitation) approved before construction may begin. A SuDS Approving Body (SAB) will be established in unitary or county local authorities to approve and, where appropriate, adopt SuDS. The Act requires the Minister to publish National Standards on the design, construction, operation and maintenance of SuDS. In order for drainage applications to be approved, the SAB must ensure that the applicant has designed the SuDS in accordance with the National Standards. Once approved, the SAB must adopt and maintain those SuDS that are functioning properly and serve more than one property.
Clearly, any future building or construction work must demonstrate compliance with SuDS through the incorporation of SuDS components into the design. In terms of the sheer area concerned, the provision of pervious surfaces must be viewed as a key component of any design measures used. GeoPave from Adbruf is a resin bound aggregate surfacing system which can be used as a component of a SuDS compliant system. GeoPave provides the surface course of a paved area and is free-draining. Of course, for the full paving construction to be considered as SuDS compliant, all the components of the construction must be SuDs compliant. It is only as good as its weakest link. However, such materials are now available in pervious sub-base and asphalt products.
GeoPave is a resin system designed to be used in conjunction with specially selected aggregates in precise proportions to produce visually stunning paved areas for pedestrian or light vehicular traffic. Such areas would typically include heritage sites, estate roads, parking areas, footpaths, cycleways, courtyards, pathways, public parks, pedestrian precincts, office buildings, landscaping schemes, schools, walkways, tree pits, patios, conservatories, gardens, playgrounds, swimming pool surrounds, disabled access ramps, roof terraces and balconies. GeoPave has been proven in use over time and over hundreds of thousands of square metres of surfacing. Using it as part of a resin bound aggregate surfacing system gives you:
- A beautiful even surface using natural materials
- A wide range of choices of different aggregates
- Sustainable Drainage Systems (SuDS) compliance
- Environmentally friendly, biomass-based resin system containing no harmful chemicals
- No odour either during or after installation
- A durable yet flexible and crack resistant surface
- Easy maintenance
- A choice of Standard or UV resistant grades (use depends on aggregate blend selected)
