Which gravel should I use for permeable flooring?
A practical guide to selecting pebbles and binders for lasting, draining surfaces
Permeable flooring systems are an essential part of modern landscaping, reducing surface water runoff and providing attractive, durable spaces. Selecting the right gravel—whether for driveways, patios, or footpaths—ensures your surfaces remain safe, functional, and beautiful even in the diverse UK climate.
This guide will demystify gravel types and highlight the best resin solutions for permeable installations, drawing on expertly matched products such as our “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin, Washed Pebbles for Permeable Floors 25kg – Outdoor Resin-Bound Surfaces, and “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit.
What Makes Gravel Flooring Permeable?
Permeable flooring enables rainfall to pass through its surface, directly replenishing the ground below and helping to prevent flooding. Using washed, natural pebbles combined with advanced resin binders creates a Permeable solution that is both resilient and sustainable. This setup—often seen in Pebble Floors—is effective across driveways, public paths, and patios.
Key attributes of a functional resin-bound permeable floor include:
- Well-graded, pre-washed gravel to avoid compacting and loss of permeability
- Specialised resin binders for durable, weather-resistant bonds
- Customisation in granule size and colour for tailored design

Frequently Asked Questions
What is a permeable floor?
A permeable floor is a surface designed to let rainwater drain through, reducing water stagnation and mitigating local flooding. This effect is achieved by combining gravel or granules with a suitable resin binder.
Which gravel offers the best drainage for resin-bound surfaces?
Washed natural pebbles—such as those supplied in our Washed Pebbles for Permeable Floors 25kg – Outdoor Resin-Bound Surfaces—provide excellent permeability for patios, paths, and gardens. Their size and natural structure help water pass freely.
Are resin-bound permeable floors suitable for car parks and driveways?
Yes. Systems like “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin are designed for vehicular and pedestrian areas, delivering strength and permeability with the right installation and materials.
Can I install permeable flooring myself?
Installation is straightforward with our step-by-step kits and guides. For larger areas, a cement mixer is useful, but smaller spaces can be managed with basic DIY skills, thanks to the helpful application instructions included in every kit.
How do I keep white gravel looking pristine in permeable floors?
Use a non-yellowing polyurethane binder like “Polirock” to preserve the bright finish of white stones over time, resisting the yellowing or fading common with epoxy binders.
What mix ratio is recommended for binder to gravel?
For white stones using Polirock, approximately 3% resin by weight is ideal, with 6 to 8 kg of aggregate per 1 kg of resin, variation depending on aggregate size and desired thickness.
Are there any weather limitations for applying resin-bound gravel?
Avoid applying resin systems in extreme temperatures or high humidity. Always follow the product documentation for best results and to ensure strong, durable finishes.
