Tarmac Resurfacing & Overlay Specialists in Kent

A tarmac overlay lays a fresh wearing course over your existing surface, and in Kent it costs around £35–£65 per m² against £70–£110 per m² for a full strip-and-relay. We’ve resurfaced driveways, car parks and private roads across Kent for over 40 years. If the base underneath is sound, resurfacing is the cheaper, faster fix, and we’ll advise if it isn’t.

When to choose resurfacing over replacement

Resurface when the base is sound and only the surface has gone: crumbling edges, a faded grey finish, surface cracking, or shallow potholing. Replace when the structure underneath is failing: sinking, deep cracks that run right through, root heave, or water that pools and won’t drain away.

That distinction is the whole job. An overlay is a new top layer bonded to what’s already there. It does nothing for a base that’s moving. Lay a fresh surface over a failing sub-base and the new top will fail the same way the old one did, usually inside three to five years.

We see two mistakes regularly. The first is homeowners assuming they need a full replacement when an overlay would do the job perfectly well, and paying twice what they needed to. The second, less common but far more costly, is a contractor selling an overlay over a base that should have come out. Both are avoidable with a survey.

A quick check before you call anyone:

• Good overlay candidate: surface looks tired, edges frayed, the odd shallow crack, but the drive sits level and drains.
• Needs a full dig-out: dips and humps you can feel underfoot, cracks wider than a pound coin, sections that have sunk, or a soft spot that springs when a vehicle sits on it.

The overlay process explained

A proper overlay is more than tipping hot tarmac on top. Skipping the prep is exactly why cheap jobs fail early. Our process runs like this:

1. Survey and assessment. We check the base is structurally sound, look at levels against your thresholds and drainage, and confirm an overlay is the right call.
2. Clean and prepare. The existing surface is swept and cleaned back to a sound, dry, debris-free face. Tarmac won’t bond to dirt, moss or loose material.
3. Repair defects first. Potholes, fretted patches and failed edges are cut out and made good before anything goes over the top. An overlay doesn’t hide a hole, it just sinks into it.
4. Apply a tack coat. A bitumen emulsion bonding layer is sprayed across the surface so the new tarmac fuses to the old. Without it, the two layers are simply stacked, not joined.
5. Lay the wearing course. Hot-mix tarmac is laid to an even depth, usually 30–50mm, in one or two passes depending on the surface and the use it’ll take.
6. Compact and finish. A roller compacts the surface to full density while it’s still hot, edges are trimmed and the joints are sealed.

Restoring crumbling bitumen surfaces

A tarmac surface “crumbles” when the bitumen binder ages out. UV, rain, frost and the odd oil drip all break down the binder over the years until the stone aggregate loses its grip and starts to come away as loose grit. The technical name is fretting. You’ll usually see it at the edges and the most-driven tracks first.

If the fretting is surface-deep and the base is still solid, an overlay restores the drive completely and resets the clock by 12–15 years. Where the binder has gone so far that the surface is breaking into the layers below, or water has been getting into the base through the cracks, an overlay alone won’t hold. That’s the judgement call we make on site rather than over the phone.

Red vs black tarmac refurbishment

Standard black tarmac suits the vast majority of resurfacing jobs and gives the cleanest, sharpest finish for the money. Red is an oxide-pigmented asphalt, laid the same way but at a premium over black, with the exact figure confirmed at survey.

Two points on colour. First, pigmented tarmac fades over time as the surface weathers, so a refurbishment in red is best paired with a re-seal at around seven to nine years to bring the colour back. Second, you can absolutely overlay in colour over an existing black or red base, so a refresh is a good moment to change the look if you’ve ever wanted to. We laid a yellow-spec drive in Folkestone with grey granite edging that came out beautifully, so colour done well is worth considering.

Curing times: when can you drive on new tarmac?

You can walk on new tarmac within a few hours, and in normal conditions you can drive on it within 24 to 48 hours. It keeps hardening for months afterwards, so the early care matters more than the headline number.

Here’s the honest timeline:

• First few hours: touch-dry, fine for careful foot traffic.
• 24–48 hours: ready for normal driving in dry, mild weather. Cold or wet conditions add a day or two.
• First few weeks: avoid turning your wheels while stationary (power steering scuffs soft tarmac), and don’t park a heavy vehicle or skip in one fixed spot.
• 6–12 months: full cure, when the surface reaches maximum hardness. Wait until this point before applying any seal.

Most early damage to new tarmac happens in the first month and it’s permanent. A few weeks of light care protects a surface that should last two decades or more.

Larger areas tend to work out cheaper per m², because the cost of bringing the gang, the roller and the hot box is similar whether we’re covering 30m² or 300m².

Frequently asked questions

Is resurfacing cheaper than a new driveway? Yes, considerably. An overlay over a sound base runs at £35–£65 per m², against £70–£110 per m² for a full strip-and-relay and more again for a garden conversion. The saving comes from keeping your existing sub-base rather than digging it out and starting over.

How many times can a tarmac drive be resurfaced? Usually once or twice over its lifetime. Each overlay raises the surface by roughly 30–50mm, so after a couple of layers you risk fouling thresholds and the damp-proof course, at which point a full dig-out is the better call.

How long does a resurfaced driveway last? A well-laid overlay over a sound base lasts around 12–15 years before the surface needs attention again. Over a failing base, even a perfect overlay can fail inside three to five years, which is why the assessment matters.

Will an overlay hide cracks and potholes? No. Existing potholes and failed patches are cut out and repaired before the overlay goes on. Laying over a hole just creates a soft spot that reappears within months.

Do I need planning permission to resurface? Resurfacing or overlaying an existing driveway usually doesn’t need permission. We cover drainage and permitted-development rules as part of every site visit.
