What does SUDs mean?
Firstly, the abbreviation SUDs stands for Sustainable Urban Drainage Systems. Basically, this means they are designed to manage surface water runoff in a sustainable and environmentally friendly manner. Therefore, when we say our resin bound surfacing are SUDs compliant, we mean that water is absorbed and drains away below the surface. Consequently, it doesn't build up on the surface. Incidentally, resin bound gravel is a type of paving system used on drives, patios and paths where aggregates are mixed with resin and laid on a surface to create a hard-wearing and permeable surface. Crucially, by applying the SUDs principles, resin bound gravels can have enhanced water management.

Here's how SUDs benefits resin bound surfacing:
Benefits of SUDs on resin bound gravel
- Permeability: One of the key features of resin bound surfacing is its permeability. Consequently, the surface allows water to pass through which reduces surface water runoff and the risk of flooding. Crucially, this aligns with SUDs principles, as permeable surfaces help to mimic natural drainage patterns and reduce the strain on traditional drainage systems.
- Infiltration: SUDs encourage water to infiltrate into the ground rather than running off into drains. Resin bound surfaces facilitate this by allowing water to seep through the surface and into the ground. Thus, helping to recharge groundwater and reducing the risk of flooding.
- Water Quality: SUDs aim to improve water quality by naturally filtering pollutants and contaminants from the runoff. Consequently, the permeable nature of resin bound surfaces can assist in trapping and filtering out pollutants from rainwater. Therefore, helping to maintain better water quality in nearby water bodies.
- Reduction of Hard Surfaces: SUDs encourage the reduction of impermeable surfaces like concrete and asphalt which contribute to increased surface water runoff. Resin bound surfacing provides a sustainable alternative by allowing water to pass through and infiltrate. Therefore, minimizing the impact of hard surfaces on drainage systems.
- Management of Excess Water: In areas with heavy rainfall, excess water can still overwhelm drainage systems despite permeable surfaces. SUDs for resin bound surfaces might involve combining them with other drainage techniques. For example, attenuation systems, swales and retention ponds to effectively manage excessive water during intense rain events.
- Local Environment Integration: SUDs often aim to mimic natural water management processes, integrating with the local landscape and ecology. Resin bound surfaces, due to their versatility and aesthetic appeal, can be designed to blend well with the surroundings while also sustainably draining water.
Final round up
In essence, SUDs for resin bound surfacing involve integrating the principles of sustainable water management with the permeable and aesthetic qualities of resin bound surfaces. Crucially, this helps to mitigate flooding, improve water quality, improve surface safety and contribute to overall environmental sustainability in urban areas. Remember, that specific practices might vary based on local regulations, climate, and site conditions.
