Selecting the right stones is key to creating an attractive and efficient permeable paving surface. The stones you choose determine the appearance, drainage, and longevity of your outdoor project.
Choosing the Right Aggregate Size and Type
For permeable paving, selecting clean, washed aggregates with a consistent grain size of 4–8 mm is recommended. This size ensures optimal drainage while providing a robust and visually appealing finish. Materials such as natural pebbles, granite, or marble chippings can be combined to achieve custom effects. Ensure all stones are dried before mixing with resin to maintain strong adhesion and prevent moisture issues.
Matching Stones with Suitable Resin Binders
The compatibility between your selected stones and the binder resin is essential for a durable, long-lasting finish. For white or light-coloured aggregates, use a non-yellowing polyurethane binder such as Polirock to keep the stones clear and bright. For coloured stones, a low-yellowing epoxy is generally suitable. If you prefer a ready-made solution, the Flowstone kit includes matched resins and guidance tailored to your aggregate choice.
When Stone Selection Matters Most
Thoughtful stone selection matters especially for driveways, patios, and paths exposed to frequent rainfall or high foot traffic. High-quality, washed pebbles such as those in the Washed Pebbles 25kg bag are ideal for ensuring long-term appeal, drainage, and low maintenance needs in these busy areas.
