Block paving vs resin bound vs tarmac: comparing driveway costs and durability

Choosing between block paving, resin bound surfacing and tarmac is usually the first real decision in a driveway project, and it’s easy to let it come down to looks alone. Price, durability and how much upkeep each one needs over the years matter just as much, especially since a driveway is a job most people only do once every couple of decades.

None of the three is objectively “best.” Each suits a different budget, style and level of ongoing attention, and the biggest cost differences often come from ground preparation rather than the surface material itself.

Tarmac: the budget-friendly, low-fuss option

Tarmac is generally the cheapest of the three per square metre, and it’s quick to lay once the sub-base and edging are in. It gives a clean, uniform finish that suits larger driveways or properties where a decorative pattern matters less than a tidy, functional surface. A well-laid tarmac driveway typically lasts 15 to 20 years before it needs resurfacing, longer with occasional sealing and prompt repair of small cracks.

The trade-off is repair visibility. A patch of new tarmac laid into an older surface rarely blends in perfectly, so localised repairs can leave a driveway looking patchworked even when it’s structurally fine.

Block paving: flexible, repairable, and a strong middle ground

Block paving sits in the middle on price and offers something the other two don’t: individual blocks can be lifted and reset if you ever need access to a drain or a cable underneath, then relaid without leaving a visible scar. It also comes in a wide range of colours and laying patterns, which makes it a common choice for period properties around Cheltenham where a uniform tarmac finish can look out of place.

A correctly built block paving driveway, with a proper sub-base and haunched edge restraints, can last 20 to 25 years or more. Jointing sand needs occasional topping up, and a small number of blocks may need re-levelling over time, but this is minor maintenance rather than a sign of failure.

Resin bound surfacing: the premium, low-maintenance choice

Resin bound surfacing costs the most to install, generally running higher per square metre than either tarmac or block paving because of the material cost and the skill needed to lay it evenly. In return, it gives a smooth, joint-free finish with a naturally permeable surface, which can help meet planning requirements around surface water drainage for front gardens. It needs very little upkeep once laid, mainly keeping it clear of moss and debris.

The main risk with resin is installation quality rather than the material itself. A resin surface laid over a poorly prepared or under-depth base will fail just as fast as any other surface, since the resin layer itself isn’t what’s providing structural strength.

Side-by-side comparison

	Tarmac	Block paving	Resin bound
Typical cost	Lowest	Mid-range	Highest
Typical lifespan	15-20 years	20-25 years or more	15-20+ years with good install
Repairability	Patches can be visible	Blocks can be lifted and reset	Harder to patch invisibly
Drainage	Not permeable unless a porous mix is used	Can be laid permeably with the right jointing	Naturally permeable when laid correctly
Maintenance	Occasional sealing, crack repair	Re-sand joints, re-level occasionally	Minimal; keep clear of debris

Weighing the decision

If keeping upfront cost down matters most and you’re covering a larger area, tarmac is usually the practical choice. If you want a surface that can be adapted or partially lifted later, and a finish that suits an older property, block paving offers a good balance of price and flexibility. If a smooth, low-maintenance finish and permeable drainage matter more than upfront cost, resin bound surfacing is worth the premium, provided the contractor you choose can show a solid track record on preparation, not just finished photos.

Whichever material you lean toward, the same rule applies across all three: the sub-base is what determines whether the driveway lasts two decades or two years, so weigh a contractor’s groundwork experience at least as heavily as which surface they specialise in. Our methodology looks at exactly this kind of workmanship evidence when scoring local contractors.
