Tarmac vs Block Paving
Which Is Right for Your Driveway?

Quick Answer

If kerb appeal and design flexibility matter most, choose block paving — it offers more pattern and colour options, and individual blocks can be lifted and re-laid cleanly. If lower upfront cost and faster install matter most, choose tarmac. Both are excellent surfaces when installed properly. Both fail badly when they're not.

Cost — What to Expect

Both surfaces vary substantially by site. The biggest factors are size, groundworks needed, drainage requirements, edging and access. As a general rule:

• Tarmac tends to be the lower-cost option upfront and is faster to install.
• Block paving tends to cost more upfront but offers more design flexibility and is straightforward to repair or lift if utilities need access in future.

Over the long term the two often work out closer than the upfront figures suggest. We always provide a free, fixed written quote after a site visit so you can compare apples to apples — no guesswork.

Durability & Lifespan

Block paving is a long-lasting surface when installed with the right sub-base, edge restraints and jointing sand. Individual blocks can be lifted and replaced if damaged.

Tarmac is also long-lasting when laid properly, but tarmac patches tend to show, so repairs are more visible than with block paving.

Both surfaces depend entirely on the sub-base. Skimp on the dig-out and either will fail prematurely.

Maintenance

Tarmac needs very little day-to-day maintenance. Optional re-sealing from time to time keeps it looking dark and slows oxidation. Edges occasionally need attention.

Block paving benefits from a kiln-dried sand top-up from time to time and occasional weed treatment in the joints. A clean every couple of years if you want it spotless.

Look & Kerb Appeal

Block paving wins for design flexibility — herringbone, basketweave, stretcher bond, contrasting borders, granite-effect blocks, tumbled finishes. You can mix colours, create patterns, and edge with a different block for definition.

Tarmac is a flat, modern, uniform black surface. Looks excellent on contemporary homes and where the goal is "clean and minimal". Looks less period-appropriate on a Victorian or cottage-style property.

Many of our recent jobs combine the two — tarmac main surface with a block paving edge, the best of both worlds.

Drainage & Planning

For driveways over 5m² you legally need to manage surface water yourself rather than running it onto the public highway. This is a SuDS (Sustainable urban Drainage Systems) requirement.

• Permeable block paving counts as SuDS-compliant by default — rainwater drains straight through the joints into a built-up sub-base.
• Tarmac is non-permeable. You'll need a soakaway, channel drain, or to drain onto a permeable area (lawn, gravel) to stay compliant.

We design drainage as part of every quote — the right solution depends on your soil, slope, and where the water can legally go.

Repair & Patch

Block paving is the clear winner. If a service trench needs cutting in 10 years' time for a new water main or fibre broadband, the blocks lift up, the work happens, and the blocks go back. Job done, no visible repair.

Tarmac patches show. They always show. A pothole repair is fine for an industrial yard but on a residential driveway you'll see the join forever.

Time to Install

Tarmac tends to be quicker to install than block paving — fewer manual steps once the sub-base is ready.

Block paving takes longer because every block is laid individually, but it's usable as soon as the jointing sand is in.

We agree a clear timeline as part of your quote and stick to it.

Which Should You Choose?

If we had to give the quick recommendation by use-case:

• Period or character property — block paving. The look matters, and you can match the brickwork.
• Modern build with simple geometry — either works. Tarmac if budget-led, block if kerb-appeal-led.
• Large drive (>100m²) — tarmac wins on cost. Add a block paving border for definition.
• Tight budget — tarmac, every time.
• Service utilities likely to need digging up — block paving. Repair invisibility wins long-term.
• Sloped access — tarmac. Blocks can slip slightly on steep gradients without proper edge restraint.
• SuDS compliance required and budget allows — permeable block paving. Skip the soakaway.

What JGS Does

We install both. After 35 years across Derbyshire we've laid roughly equal amounts of each, and we're happy to talk you through which makes more sense for your specific property — not which makes us the most margin.

Either way, the dig-out, sub-base, drainage, edging and finish all matter just as much as the surface choice. We do all of it ourselves — no subcontractors — and back every job with a workmanship guarantee.
