Custom Aggregate Mixes for Resin Bound Gravel in Courtyards

Customising an aggregate mix gives you the freedom to design a truly unique, robust, and permeable resin bound courtyard. With the right choice of pebbles, binders and blend, you can achieve a decorative surface that matches your requirements.

Building Your Bespoke Aggregate Mix

Start by selecting aggregates that complement your courtyard’s desired look and functional needs. Washed and dried natural pebbles, marble, or granite granules can be blended to achieve varied textures, colours, and drainage properties. The typical pebble size (around 4–8 mm) ensures an even, stable finish. You can combine different hues and grain sizes for a finish ranging from contemporary neutrals to eye-catching colourways. Remember to select only clean, dry aggregates, as moisture can affect binding and appearance.

Choosing the Right Resin Binder

Pair your aggregate mix with a suitable binder to ensure cohesion and durability. For white or pale stones, a non-yellowing polyurethane binder such as Polirock keeps the surface looking bright. For coloured or darker mixes, opt for a UV-resistant epoxy binder like Trasparente for long-lasting clarity and colour stability. The binder and stone are thoroughly mixed before being applied, creating a seamless, water-permeable surface suitable for outdoor courtyards.

Tips for Custom Results and Installation

Test your blend before full installation to ensure the colour and texture meet your expectations.
Follow the recommended resin-to-stone ratios – for most outdoor mixes, around 3% resin by aggregate weight is a solid guideline.
Apply the mix promptly after combining, as resins have limited working times.
Consider professional kits, such as the Flowstone Complete Permeable Floor Kit, for step-by-step guidance and materials sized by area.

When Custom Mixes Matter Most

Opting for a tailored aggregate and resin combination is especially valuable in courtyards where design continuity, specific drainage needs, or unique colours are priorities. If you have a challenging setting or want a signature look, custom mixes provide the versatility required.
