What Is a Permeable Resin Bound Floor? Guide & Uses

← Back to What is the best aggregate for resin bound paving?

Permeable resin bound floors are designed to let water pass through their structure, making them an effective surface for outdoor areas where drainage and surface water control are important.

How Permeable Resin Bound Floors Work

These floors use a mixture of natural aggregates—such as pebbles or stone chips—combined with a strong resin binder. The resulting surface is stable underfoot yet porous, allowing rainwater to travel through the gaps between granules rather than pooling on top. This permeability helps reduce flood risk, eliminates persistent puddling and encourages natural water dispersion into the ground beneath.

Choosing Materials for Permeable Surfaces

Selecting the right combination of aggregates and resin is essential for longevity and effectiveness. For white stones, a non-yellowing polyurethane binder such as the Polirock Two-Component Polyurethane Binder is recommended to keep the appearance clear and bright. Coloured or natural stones are often paired with a durable epoxy binder like Trasparente, designed to offer UV resistance while maintaining vibrant aggregate tones. Complete kits, such as Flowstone, include carefully selected resin and aggregates for balanced drainage and durability, suitable for both DIYers and professionals.

When Is Permeability Important?

Driveways and paths prone to water runoff or pooling
Paving in gardens, patios, or public spaces where flood prevention and safety are priorities
Urban environments where hard surfaces need to comply with drainage requirements
