Lay a resin-bound patio.

Resin bound is the smooth, permeable, modern outdoor surface — a mix of clear UV-stable resin and decorative aggregate trowelled out flat. It has no joints, drains naturally through itself, and looks more polished than resin bonded (its messier cousin). This guide covers what a resin bound patio costs in 2026, the install detail, and how it compares to other modern surfaces.

It's a permeable paving system — water passes through the cured surface into the base below. That makes it SuDS-compliant without separate drainage, which is increasingly valuable for front gardens.

What Does the Work Involve?

• Excavation and 100 mm compacted MOT Type 1 sub-base.
• 40–50 mm permeable base layer (open-graded asphalt or concrete).
• Trowel-applied resin + aggregate mix, typically 15–18 mm thick.
• Self-levelling within 2–3 hours; full cure in 24 hours.
• Edging — aluminium or stone — to contain the resin during pour.

Typical Costs

The aggregate colour determines a lot of the price — pale neutrals are cheapest; specialty quartz blends cost more.

How Long Does It Take?

• Sub-base prep: 1–2 days.
• Permeable base + cure: 1–2 days.
• Resin pour and trowel: 1 day for 20 m².
• Walkable: 24 hours; full strength: 7 days.

DIY or Professional?

Resin bound is technically achievable for a confident DIYer — but the application window is short and the cost of getting it wrong is high (the whole surface fails). Most owners hire specialists who carry the right mixing equipment and warranties.

Choosing the Right Tradesperson

• Confirm they're an approved installer for the resin brand (Sureset, Addaset, Resincoat, etc.).
• Ask about UV stability of the resin — cheap resins yellow in sunlight.
• Look at jobs at least 3 years old — the surface should look the same as new.
• Confirm the permeable base specification — this is what gives SuDS compliance.
• 10-year warranty on the resin surface is standard.

UK Regulations

• Fully SuDS-compliant — water drains through the surface to the base.
• No planning permission needed for permeable paving in front gardens regardless of size.
• One of the easiest paving types for front-garden compliance.

Common Problems

• UV yellowing — cheap resins yellow in sunlight. Specify UV-stable (aliphatic) resin.
• Surface picking — aggregate dislodging in heavy traffic. Usually means the mix was wrong or surface was over-trowelled.
• Pooling water — base layer not truly permeable. Test with a hose before sign-off.
• Algae growth in damp areas — same issue as any other surface; annual treatment.
• Difficulty repairing — small damage can be patched; large damage usually means re-doing the whole panel.
