How Long Does a Driveway Last? Block Paving, Tarmac & Resin Compared

Driveway Lifespans at a Glance

• Block paving: 25–40 years with correct sub-base
• Tarmac: 20–30 years
• Resin bound: 15–25 years
• Pattern imprinted concrete: 20–30 years
• Loose gravel: Indefinite but requires ongoing top-up and maintenance

These figures assume a professionally installed surface on a properly prepared sub-base. A cheap installation with a poor foundation will fail in years, not decades — regardless of surface type.

The Most Important Factor: The Sub-Base

Every driveway installer will tell you the surface is what matters. That's wrong. The sub-base is everything.

A correctly installed MOT Type 1 sub-base — compacted to 100–150mm depth to BS 7533 standard — distributes the load of vehicles evenly and prevents settlement, cracking and rocking. A poor sub-base or an inadequate depth causes blocks to sink, tarmac to crack and resin to delaminate.

When comparing quotes, ask every installer what depth of sub-base they specify and what compaction standard they work to. Any answer below 100mm compacted should raise a red flag.

Block Paving: 25–40 Years

Block paving lasts longer than any other common driveway surface when correctly installed. Individual blocks can be lifted and replaced if cracked or stained — meaning the driveway can effectively be maintained indefinitely. The main maintenance requirements are:

• Re-sanding of joints every 5–10 years as kiln-dried sand migrates
• Occasional jet washing to remove algae and staining
• Weed treatment if weeds establish in joints

Tarmac: 20–30 Years

Tarmac is extremely durable for vehicle loads and handles the UK's freeze-thaw cycle well. Its lifespan is affected mainly by:

• UV degradation — tarmac softens in very hot weather and hardens and becomes brittle in cold
• Edge cracking where haunching isn't present
• Root damage from adjacent trees
• Fuel or oil spillages which degrade the binder

A resurfacing overlay is usually possible after 15–20 years rather than a complete dig-out, extending the total lifespan cost-effectively.

Resin Bound: 15–25 Years

The lifespan of resin bound driveways varies more than other surface types because quality varies enormously between installers. Key factors include:

• UV stability of the resin — cheap resins yellow and degrade within 5–10 years
• Quality of the aggregate and correct mixing ratio
• Whether it was laid over a sound existing surface or a new sub-base
• Thickness of the resin layer

A quality resin bound installation using UV-stable polyurethane resin and natural aggregate on a sound sub-base should last 15–25 years with minimal maintenance. Repairs are harder than block paving — a patch repair in resin will always be slightly visible.

What Reduces Driveway Lifespan?

• Poor installation — inadequate sub-base is the biggest cause of premature failure
• Heavy vehicle use — skips, lorries and caravans place far more load than cars
• Tree roots — growing under the surface can lift and crack any surface type
• Standing water — poor drainage causes freeze-thaw damage and sub-base saturation
• Chemical spillage — fuel and oil degrade tarmac and resin binders

How to Make Your Driveway Last Longer

The single most effective thing is to choose an installer who specifies and delivers a proper sub-base. Beyond that: keep drainage clear, address any cracking or settlement promptly before it spreads, and re-sand block paving joints as needed.
