Tarmacadam — tarmac for short — is a mixture of crushed stone aggregate bound with bitumen, rolled and compacted to create a smooth, hard-wearing surface. It's the same material used on most UK roads, which gives you a sense of how durable it is under constant traffic. Standard black tarmac is the most popular choice, but red tarmac is also available for a more distinctive look — often used for paths, borders, or to match existing brickwork.
Tarmac works well for both new installations and resurfacing. If your existing driveway surface is structurally sound — whether it's old tarmac, concrete, or compacted aggregate — a new tarmac layer can often be laid directly on top as an overlay. This saves the cost and disruption of full excavation while giving you a fresh, level finish. We also install tarmac for commercial forecourts, car parks, and access roads where durability and quick turnaround are priorities.
Tarmac is consistently the most affordable option when compared to block paving, resin bound, or gravel on a like-for-like area basis. Installation is fast — most residential driveways are completed within one to two days, minimising disruption to your daily routine. The surface is ready for vehicle traffic within 24 to 48 hours depending on weather conditions.
A properly installed tarmac driveway lasts 12 to 20 years with basic maintenance. The surface handles heavy vehicle loads well, resists cracking in moderate frost conditions, and gives a clean, neat finish to any front-of-house. If the surface eventually wears, it can be resurfaced with a fresh tarmac layer without the need for full excavation — extending the driveway's life by another decade or more. Sealing the surface every few years further extends its lifespan and keeps it looking sharp.
Tarmac is the lowest-cost driveway surface per square metre, making it popular with homeowners who want a smart finish without a premium price tag. The total cost depends on the area to be covered, whether the tarmac is laid as a new installation or as an overlay on an existing surface, and how much groundwork is needed. Overlay installations are significantly cheaper because they skip the excavation and base-laying stages.
Ground conditions matter too — if your existing surface needs removing, the driveway slopes, or drainage channels are required, the groundwork cost increases. We always quote after visiting the property, never over the phone. You'll get an itemised breakdown within three days of the visit covering excavation, sub-base, tarmac, edging, and waste removal. No hidden costs, and no deposit required.
Tarmac Driveways Across Berkhamsted & the A41 Corridor
We install and resurface tarmac driveways across Berkhamsted, Hemel Hempstead, Tring, Aylesbury, and surrounding areas — residential and commercial.
Often, yes. Laying new tarmac over an existing surface — sometimes called a tarmac overlay or resurfacing — is one of the most common and cost-effective driveway improvements. It works best when the existing surface is structurally stable with no major subsidence, large cracks, or significant drainage problems. Old tarmac and concrete are the most common bases for overlay work.
The existing surface is cleaned, any loose material is removed, and a bonding layer is applied before the new tarmac is rolled on top. The result is a fresh, level surface at a fraction of the cost of a full dig-out. Where the existing base has failed — tree root damage, deep potholes, or persistent drainage issues — we'll recommend excavation and a new sub-base instead. We assess this on site and advise honestly. There's no point overlaying a failing surface; it'll just crack through again.
Tarmac driveways are low maintenance by nature, but a small amount of care extends their life significantly. In the first 12 months, avoid parking in the same position every day — the surface softens slightly in warm weather during this curing period and can develop tyre marks. After the first year, the tarmac fully hardens and this is no longer a concern.
Sealing a tarmac driveway every three to five years protects it from UV damage, prevents the surface from drying out and cracking, and restores the deep black finish. Small cracks and minor surface damage can usually be patched without a full resurface — something we can handle as part of our driveway repair service. Keep the surface clear of weeds and moss, and a tarmac driveway will comfortably last 15 to 20 years before it needs attention.
