Base Preparation for Resin Permeable Floors

← Back to How do you make a resin permeable floor?

The foundation of a successful resin permeable floor starts with careful and correct base preparation. An effective base ensures proper drainage, lasting strength, and the overall performance of your outdoor surface.

What Makes a Good Base for Permeable Resin Floors?

For permeable resin-bound systems, the base acts as the drainage platform beneath your decorative layer. A typical choice is a compacted, free-draining MOT Type 3 sub-base, which resists water pooling and supports the intended permeability. It’s essential the surface is free of loose debris, stable, and level before proceeding.

Check the ground is solid and slopes away from buildings to prevent water accumulation.
Repair cracks or dips, as unevenness can weaken the finished floor or affect drainage.
If moisture could be an issue, consider adding a permeable membrane between sub-base and aggregate to keep fine particles from rising.

Choosing the Right Aggregates and Resin Binders

Once your base is sound, select clean, well-graded aggregates to maintain permeability. Washed Pebbles for Permeable Floors 25kg are pre-washed and dried, making them ideal for combining with resin binders. For binding, choose specialist products like transparent epoxy or polyurethane binders that evenly coat the aggregate without clogging gaps.

Mix aggregate and binder thoroughly before application for strength and stability.
Follow supplier guidance for resin-to-aggregate ratios; this typically impacts the balance between strength and water flow.

When Base Preparation Really Matters

Proper base preparation is especially important for areas prone to heavy rain, as inadequate drainage can lead to surface damage and pooling. If you plan for high footfall or occasional vehicles, extra care must be taken to achieve a well-compacted and stable foundation that supports the resin-bound layer above.
