Tarmac vs Block Paving
Which Is Right for Your Driveway?

Quick Answer

If kerb appeal and longevity matter most, choose block paving — it lasts 25-30 years, looks more characterful, and individual blocks can be lifted and re-laid. If speed of install and lower upfront cost matter most, choose tarmac — a typical drive is finished in 2-4 days and costs 20-30% less per square metre. Both are great surfaces when installed properly. Both fail badly when they're not.

Cost — What You'll Actually Pay in Derbyshire

Both surfaces vary by site, but Derbyshire prices in 2026 typically fall in these ranges:

Over a 30-year horizon, block paving often works out about the same or slightly cheaper than tarmac because tarmac usually needs full resurfacing once in that window. Don't choose on upfront price alone — ask for lifetime cost in your quote.

Durability & Lifespan

• Block paving: 25-30 years with proper sub-base, edge restraints and kiln-dried jointing sand. Individual blocks can be lifted and replaced if damaged.
• Tarmac: 15-20 years typically. Will need resurfacing or full replacement after that. Repairs are visible — patch jobs almost always show.

Both surfaces depend entirely on the sub-base. Skimp on the dig-out and either will fail in 3-5 years.

Maintenance

Tarmac needs almost no day-to-day maintenance. Optional re-sealing every 4-5 years (£3-£6/m²) keeps it looking dark and slows oxidation. Edges occasionally need patching.

Block paving benefits from a kiln-dried sand top-up every 2-3 years (we'll do this if you want, or you can DIY for the cost of a bag of sand). Occasional weed treatment in the joints. A power-wash 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: typically 2-4 days total (sub-base + tarmac laying day + finishing).

Block paving: typically 3-5 days total (sub-base + edging + block laying + jointing).

Block paving is usable as soon as the kiln-dried sand is in. Tarmac needs 24-48 hours before parking heavy vehicles and 7-14 days before any tight turning while the binder fully cures.

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.
