How should I prepare the base for resin-bound aggregate?

← Back to How to make a floor using aggregate and resin?

Achieving a smooth, long-lasting resin-bound aggregate floor starts with correct sub-base preparation. The initial groundwork lays the foundation for durability and drainage.

Choosing the Right Sub-Base

For best results, opt for a solid, stable material such as concrete or well-compacted, level MOT Type 1 gravel. A properly constructed sub-base provides the necessary support and prevents settlement or cracking over time. Avoid loose or uneven ground, as this can compromise the performance of your resin-bound surface.

• Concrete slabs should be clean, dry, and free of cracks.
• Compacted gravel must be evenly graded to ensure a level finish.

Cleaning and Assessing the Surface

Before laying the resin and aggregate, clear away debris, moss, oil, and dust. Use a pressure washer or stiff broom for thorough cleaning, and repair any visible cracks or holes in concrete. The base must be dry for resin application, so avoid starting the project after rain or in high humidity.

When This Matters

Proper base preparation is especially important for high-traffic areas such as driveways or footpaths. A strong sub-base helps ensure your resin-bound floor withstands vehicles, footfall, and the effects of British weather. For outdoor installations, products like the Flowstone permeable floor kit make it easy to achieve a durable result.
