Mixing aggregates is a crucial step when installing permeable resin-bound flooring. The right blend of stones and binders ensures a durable surface that allows water to drain away efficiently, keeping your outdoor areas safe and attractive.
Selecting Suitable Aggregates
Start by choosing washed and dried stones intended for permeable flooring to prevent issues with resin curing and surface appearance. Washed Pebbles for Permeable Floors are ideal for paths, patios, and driveways, offering excellent drainage and a natural look. You can customise your mix with different types and sizes of aggregates, such as marble or granite granules, for a unique finish.
Mixing Techniques and Best Practices
To achieve effective binding and permeability, always mix your chosen aggregates with a compatible resin—never pour resin directly over loose gravel. For coloured or natural-tone stones, an epoxy binder like “Trasparente” is advisable. For white or light stones, use a non-yellowing polyurethane binder such as “Polirock”. Combine the pebbles and resin thoroughly in a cement mixer or large container to ensure every stone is coated. Work on dry days and keep all materials free of moisture for the best results.
When Mixing Aggregates Correctly Matters Most
Proper mixing is especially important in areas with frequent rain or foot traffic, such as driveways, paths, and patios. Inconsistent mixing or damp aggregates can cause weak spots, reduced drainage, or discolouration—potentially shortening the life of your flooring.
