Tarmac and resin bound are often compared because both create a continuous finish without individual blocks. The choice usually comes down to budget, drainage, appearance and how the drive will be used. RKG's service pages give enough factual guidance to make the first decision without inventing claims or guessing site conditions.
Quick answer
Choose tarmac when you want a durable, lower-cost surface for daily vehicle use, longer drives, commercial areas or sloped drives. Choose resin bound when permeability, kerb appeal, colour choice and a premium low-maintenance finish matter more than the lowest installed price.
Tarmac vs resin at a glance
| Factor | Tarmac | Resin bound |
|---|---|---|
| Indicative installed cost | £145–£185 per m² | £185–£240 per m² |
| Typical lifespan | 15–20 years | 15–25 years |
| Drainage | Non-permeable, so drainage needs designing in | Permeable and SuDS-compliant when installed on the right base |
| Best fit | Daily-use drives, access roads, commercial areas and gradients | Premium residential drives, visible frontages and homes needing a permeable finish |
| Finish | Smooth black surface, with coloured options available | Jointless aggregate finish with 20+ colour options |
| Maintenance | Low; sealing every 3–5 years can extend life | Very low; UV-stable resin avoids yellowing |
Where tarmac is the safer recommendation
RKG describes tarmac as a strong fit for residential driveways, courtyards, access roads and commercial yards. It is hot-rolled over a compacted sub-base, with binder and surface courses creating a dense, continuous finish. On the existing sloped-driveway guide, tarmac is the strongest all-round option for gradients because it avoids loose-stone movement and provides a reliable vehicle surface.
Tarmac is also usually the lower-cost route. The current service page lists £145–£185 per m², compared with £185–£240 per m² for resin bound. That difference can matter on a long Oxfordshire or Berkshire drive where the surface area is large.
Where resin bound is the stronger choice
Resin bound is the more premium finish. RKG's resin page describes UV-stable resin mixed with kiln-dried aggregate, trowelled into a smooth jointless surface. It is permeable and SuDS-compliant when installed on the correct base, which makes it useful where front-drive drainage and planning friction are concerns.
The finish is also more design-led. RKG references 20+ aggregate colours, including warm Cotswold-style tones, silver birch and bronze blends. If the driveway is a prominent part of the frontage and the budget allows, resin gives more control over the final look.
Drainage and planning differences
The drainage difference is the main technical split. Tarmac is non-permeable, so larger front-drive projects need water managed through falls, channel drains, soakaways or run-off to a permeable border. Resin bound is permeable when the whole build-up is specified correctly, but it still needs the right base, edge restraints and levels.
If planning permission or surface water is the concern, read the planning and drainage guide before comparing quotes. The quote should say where the water goes, not just what the surface looks like.
Overlay vs full dig-out
Both surfaces may avoid a full dig in the right circumstances, but only when the existing base is structurally sound and drainage already works. RKG's resin page says resin can overlay sound tarmac or concrete with a 15–20mm layer after inspection. The tarmac page also describes surface dressing or overlay where an existing tarmac drive is sound but tired.
If the existing drive is cracked, soft, badly drained or moving, the cheaper overlay route may not be suitable. A good quote should spell out whether the job includes excavation, geotextile, MOT Type 1, binder course, edging, drainage and waste removal.
How to decide before requesting a quote
- Pick tarmac if the drive is long, heavily used, sloped, commercial or budget-sensitive.
- Pick resin bound if you want a permeable, premium-looking surface with more colour control.
- Ask about drainage either way, especially for front drives over 5m² or surfaces falling toward the house, garage or highway.
- Ask about the base because both surfaces depend on preparation more than the visible finish.
