This is a rough estimate. Dropping kerbs, rerouting drainage, and removing massive hidden tree roots will incur significant extra costs.
Guide to Buying a Tarmac Driveway
Tarmac provides an incredibly smooth, durable, and weather-resistant surface for parking. When compared to block paving or resin, it remains the undisputed champion of value for money. However, a common misconception is that the tarmac itself is the expensive part.
The Secret Cost: The Sub-Base
A tarmac driveway is only as good as what lies beneath it. The biggest cost of a new driveway is almost never the hot black stuff poured on top—it is the brutal physical labour and plant hire required to dig out tons of earth.
If you are converting a front lawn into a driveway, a contractor must bring in a mini digger, excavate down at least 150-200mm, hire multiple skips to dispose of the soil, lay a weed membrane, and then import and compact tons of crushed stone (MOT Type 1). Only after all this does the tarmac arrive. This is why "grass to drive" conversions cost significantly more than breaking up old, failing concrete.
Types of Tarmac/Asphalt
Standard Black Macadam
The standard product used for decades. It usually consists of a heavier structural "base course", followed by a finer, smoother "wearing course" on top.
SMA (Stone Mastic Asphalt)
A more modern, premium variation. It has a higher concentration of coarse aggregates and binders, making it less prone to scuffing and wheel-rutting from heavy modern SUVs. Highly recommended.
Red Tarmac
Mechanically identical, but red pigment is added during the heating process at the plant. Unsurprisingly, this custom pigmentation significantly increases the cost of the material.
