Deciding between tarmac and resin-bound surfacing

Resin-Bound vs Tarmac Driveways

Tarmac and resin-bound are often mentioned together because resin is frequently laid over tarmac. They are, however, very different products serving different priorities.

One is a structural black-top surface, the other is a decorative permeable wearing course.

Cost and speed

Tarmac is generally the lower initial cost per square metre and can be laid quickly over a large area, which is why it dominates on longer driveways and shared accesses.

Resin costs more per square metre but frequently uses the tarmac as its base, so the two are complementary rather than strictly competing.

Drainage and appearance

Standard tarmac is impermeable, so a new front driveway may need drainage designed in to satisfy the rules on paving front gardens. Resin-bound over a permeable base drains through the surface.

Visually, tarmac gives one finish. Resin comes in a wide range of aggregate blends and can incorporate borders and patterns.

Wear and repair

Tarmac softens in prolonged heat and can be marked by turning wheels, jacks and stands. It is easily patched, though patches always show.

Resin resists softening, does not scuff in the same way and cleans easily, but a repair is a cut-out and re-lay.

Frequently asked questions

Can resin go straight over tarmac?

Yes, if the tarmac is sound and stable — it is one of the most common bases we overlay.

How long should tarmac cure before overlaying?

New tarmac needs time to cure and stabilise first; we advise on timing case by case.

Which suits a long driveway?

Tarmac on cost, resin on appearance and drainage — many long drives use tarmac with a resin apron near the house.
