Sustainable Drainage System (SuDS)
Rainwater percolates naturally through the earth when it falls on natural earth such as turf and soil. New driveways, pathways and other large areas are required by the Environment Agency to be compliant with drainage standards and SuDS (Sustainable Drainage System) offers an excellent option to achieve this result.
Large areas of impermeable surfaces mean rainwater enters our mains drainage systems quickly and can cause flooding. The Environment Agency recommends surfaces which are SuDS compliant in order to alleviate local flooding and water pollution. Resin bond rubber and aggregate when installed on a permeable base achieves full compliance.
Resin Bound Systems & SuDS
Not all resin bound system are SuDS (Sustainable Drainage System) compliant. In order to be SuDS compliant they must drain into earth or natural turf. A resin bound system, a special concrete base or a compacted aggregate base is required to allow drainage. A resin bound system can be laid on old bitmac or concrete but a drainage system to natural earth must be installed in order to reach compliance. SSP can undertake all aspects of a SuDs installation and ensure compliance with Environment Agency standards.
A resin bound system can be either a wet pour rubber system or a mixture of aggregate and rubber. The addition of an aggregate make the surface more hard wearing. Wet pour rubber surfaces alone are not ideal for parking spaces. Driving cars or other vehicles over Wet Pour rubber surfaces is not recommended.
The rubber crumb and aggregate are bound together with a resin. The small pieces of rubber and aggregates have air spaces between them which allows water to percolate through it and then through the porous base, achieving both drainage and durability.
