Aggregate Types for Permeable Patio Surfaces

← Back to Selecting the Best Aggregate for Patio Projects

Creating a patio that handles rainfall efficiently relies on the right choice of aggregate. Permeable patio surfaces not only reduce water pooling but also help manage surface runoff and increase safety outdoors.

Recommended Aggregates for Permeability

For patios where water drainage is a priority, natural washed pebbles are a standout option. They are chosen for their ability to let rainwater pass through when combined with a suitable resin binder. This blend creates a stable yet open structure that directs moisture away from the surface, greatly reducing puddles even during heavy showers.

Pre-washed stone ensures the best bond with resin, resulting in a durable, easy-care finish. If you want additional design flexibility, you can mix pebbles with decorative granules such as marble or granite to achieve tailored colours and textures.

Choosing and Applying Aggregate

When selecting aggregate for your patio, opt for stones that are specifically washed, as impurities may compromise drainage. The Washed Pebbles for Permeable Floors 25kg are ideal for this use, as they are prepared for straightforward mixing and application with resin binders. Application is generally hassle-free, requiring the pebbles to be evenly mixed with resin and trowelled onto the prepared surface. For best results and colour stability, follow the guidance on resin type based on your selected aggregate.

When Permeable Aggregates Matter

Permeable aggregates make a significant difference in areas prone to standing water or where sustainable drainage is needed. They are especially valuable for patios that see frequent use in all weathers, or where you want to keep pathways safer and free from slips.
