Tarmac or Block Paving: Which Driveway Type Is Easier to Maintain?
Tarmac and block paving need very different care. Here is how the two surfaces compare for cleaning, weeds, oil stains and repairs.
Tarmac and block paving are both popular driveway choices. Like all surfaces, they need cleaning to stay looking their best. The two are quite different to maintain: tarmac generally needs less day-to-day attention but careful, gentler cleaning, while block paving needs more regular upkeep but is straightforward to repair in sections.
This guide compares tarmac and block paving from a cleaning and maintenance point of view, so you know what to expect from each and why the right cleaning technique differs between them.
The key difference
Tarmac is a continuous surface of stone bound with bitumen, with no joints. Block paving is made of individual blocks with sand-filled joints. That difference drives everything. Tarmac has no joints to re-sand or weed, though it is softer and needs gentler pressure, while block paving needs weed clearing and re-sanding yet tolerates firmer cleaning.
Cleaning comparison
Here is how the two surfaces compare across the things that matter most.
| Factor | Tarmac | Block paving |
|---|---|---|
| Day-to-day upkeep | Lower | Higher |
| Cleaning pressure | Gentler, to protect the surface | Tolerates firmer cleaning |
| Joints and weeds | No joints to weed | Weeds grow in joints |
| After cleaning | No re-sanding needed | Requires re-sanding |
| Oil and fuel | Stains and can soften | Stained blocks can be replaced |
Tarmac needs a careful, lower-pressure approach to avoid surface damage, while block paving needs the extra re-sanding stage.
Tarmac is softer, so excessive pressure can damage it and gentler cleaning is needed.
Block paving joints need weeding and re-sanding, which tarmac avoids entirely.
Tarmac absorbs oil and fuel, creating dark patches that are hard to remove.
Individual blocks replace neatly, while tarmac patches show against the weathered surface.

Which is easier to maintain?
Tarmac wins on day-to-day simplicity, since there are no joints to weed or re-sand, though it needs gentler cleaning and is vulnerable to oil and fuel staining. Block paving needs more regular upkeep including re-sanding, which we explain in our guide on what block paving re-sanding involves. It is, however, far easier to repair in sections.
Staining and technique
Tarmac is especially prone to oil and fuel marks, which sink in and are hard to lift, while block paving can have stained blocks replaced. Understanding what causes these marks helps, as covered in our guide on what causes stains on London driveways. If you are also comparing concrete, see how block paving and concrete compare.

Frequently asked questions
Which is easier to maintain, tarmac or block paving?
Tarmac needs less day-to-day upkeep with no joints to weed or re-sand, though it does need gentler cleaning. Block paving needs more attention but is easier to repair in sections.
Does tarmac need gentler cleaning?
Yes. Tarmac is softer than block paving, so excessive pressure can damage the surface. A careful, lower-pressure technique protects it.
Why does block paving need re-sanding?
Cleaning washes the jointing sand out of block paving, so fresh kiln-dried sand is brushed back in to keep the blocks stable and resist weeds.
Which handles oil stains better?
Block paving, because stained blocks can be lifted and replaced. Tarmac absorbs oil and fuel, leaving dark patches that are difficult to remove.
Do weeds grow in tarmac?
Rarely. Tarmac is a continuous surface with no joints, so weeds have nowhere to root, unlike the sand-filled joints in block paving.
