Facebook← Back to Is Resin Bound Gravel Permeable in the UK?
Resin bound gravel is increasingly popular for driveways and outdoor spaces across the UK. Homeowners and professionals alike want to know if this surface is genuinely permeable and how it compares to traditional paving alternatives.
How Does Resin Bound Gravel Achieve Permeability?
With resin bound gravel, washed pebbles or aggregates are thoroughly coated in a specialist resin and then laid onto a suitable base. This creates a strong, continuous surface where small gaps remain between the bound stones, allowing water to pass through. When correctly installed over a prepared sub-base, this system provides genuine permeability. This feature means rainwater drains through the surface, helping prevent puddles and reducing surface run-off, which is important for Sustainable Urban Drainage Systems (SUDS) compliance in the UK.
Installation and Buying Considerations
To ensure the surface remains permeable, it’s key to follow product-specific installation instructions. Always use the recommended ratio of resin to aggregate and select high-quality, washed pebbles for best results. For decorative effects and long-term colour stability, opt for UV-resistant binders such as the “Trasparente” Epoxy Binder for coloured pebbles. The Flowstone Complete Permeable Floor Kit offers a straightforward solution with clear guidance, ideal for DIY or professional projects. Suitable preparation of the sub-base and correct application ensure water can pass through and the surface remains durable.
When This Matters
Choosing a permeable resin bound system really matters for areas at risk of flooding, frequently used driveways, paths, and patios in the UK’s wet climate. It is especially beneficial in zones where compliance with SUDS regulations is required, or where surface water management is a priority.
