Resin Bound vs Tarmac Driveways: Which Should You Choose?

Resin bound and tarmac are both bituminous-linked surfaces in the broad sense, but they're fundamentally different products with very different characteristics:

| | Resin Bound | Tarmac | |---|---|---| | Cost | £80–£150/m² | £60–£90/m² | | Colour | Natural aggregate | Black | | Permeable | Yes | No (standard) | | Planning permission (front) | Not required | May be required | | Maintenance | Very low | Low | | Lifespan | 15–25 years | 20–25 years | | Installation time | 1 day | 1–2 days |

Resin bound is a premium surface with more design flexibility and no planning permission implications. Tarmac is more cost-effective and quicker to install, but limited in appearance and impermeable.

This is perhaps the biggest differentiator between the two surfaces.

Resin bound is available in a wide range of aggregate colours and mixes — from natural warm tones (golden amber, autumn blend) to contemporary options (silver quartz, slate grey, white calcite). The smooth, seamless surface shows the individual stone aggregate through the clear resin binder, creating a natural-yet-refined appearance. It's highly customisable and can be specified to complement the property's brick or stone colour.

Tarmac comes in one standard colour: black. It can be combined with a block paving or granite sett border for a more defined, finished look, and coloured macadam is available in limited options (red, green) at a premium. But fundamentally, tarmac is a uniform dark surface with no pattern or texture variation.

For most homeowners where appearance is a significant consideration, resin bound wins clearly on aesthetic range. For those who prefer a clean, functional, unfussy finish, tarmac is a legitimate choice.

This is a crucial practical difference for front driveways:

Resin bound: Fully permeable — water drains through the surface body into the sub-base. Planning permission is not required for front driveways.

Standard tarmac: Impermeable — water runs off the surface. Planning permission is required for front driveways over 5m² unless drainage provision is made to direct runoff to a suitable area on the property.

In practice, most Manchester homeowners don't pursue planning permission for a tarmac driveway and instead manage drainage by directing runoff to an adjacent planted area or lawn. However, this should be properly engineered rather than assumed — and technically requires compliance with planning requirements.

For homeowners who want the simplest route to a new driveway without planning complexity, resin bound has a clear advantage.

For a typical 50m² driveway in Manchester:

Resin bound over existing sound base: £4,000–£6,000 Resin bound with full new base: £6,000–£9,000

Tarmac resurfacing over sound base: £1,500–£2,500 Full tarmac installation: £3,500–£5,500

The cost difference is significant — resin bound is typically 40–60% more expensive than tarmac for a full new installation. However, the maintenance costs of resin bound are very low once installed, whereas tarmac requires periodic sealing and crack repair.

Over a 20-year period, factoring in maintenance, the lifetime cost difference between the two narrows — though resin bound remains the more expensive option in most scenarios.

Choose resin bound if: - Appearance is a priority and you want a premium, modern finish - You want to avoid planning permission complications for a front driveway - You want the absolute minimum in long-term maintenance - You're willing to invest more upfront for a longer-lasting, better-looking result - Your existing base (tarmac or concrete) is sound — resin over an existing base significantly reduces cost

Choose tarmac if: - Budget is the primary consideration - You need the work completed very quickly - You have a large driveway where the cost saving over resin bound is substantial - You're happy with a plain, functional finish and intend to use a block paving border for definition - You're resurfacing an existing tarmac base in sound condition
