If you're comparing options for a new driveway, one of the most common questions is “Is a tarmac drive cheaper than block paving?” In almost every situation, yes - a tarmac drive is significantly cheaper than block paving, both in terms of installation costs and long-term maintenance. But price is only one element to consider. The choice between the two materials also involves durability, appearance, practicality and how much ongoing work you want to take on.
This article breaks down the true cost differences between tarmac and block paving, explores what you get for your money, and helps you decide which option suits your property.
Is a tarmac drive always cheaper than block paving?
In the majority of cases, tarmac is the more affordable option, often by a wide margin. The reason is simple: tarmac can be machine-laid quickly, uses fewer materials, and requires much less labour compared to laying hundreds or thousands of individual blocks.
Block paving, by contrast, is extremely labour-intensive. Every block must be laid by hand, levelled, aligned, cut where needed, and compacted - meaning labour makes up a large portion of the cost.
Typical cost comparison: tarmac vs block paving
Although prices vary by region, ground conditions and layout, here's a general guideline for the UK:
- Tarmac driveway: typically cheaper upfront
- Block paving driveway: usually 30-70% more expensive
Some installations can be double the cost of an equivalent tarmac area if premium blocks or intricate patterns are chosen.
Why is tarmac cheaper to install?
Faster installation
Tarmac can be laid in a matter of hours on smaller areas and usually within a day or two on larger driveways. Block paving can take days or even weeks depending on size and detailing.
Lower labour costs
Laying tarmac is machine-driven, whereas block paving is almost entirely manual. Labour is the biggest cost difference between the two.
Fewer materials
Tarmac uses less raw material per square metre and no decorative blocks or borders unless specified.
Minimal wastage
Block paving requires cutting, shaping and adjusting to fit curves, edges or features. This adds time, cost and potential waste. Tarmac flows to fit any shape efficiently.
Is a tarmac driveway cheaper to maintain?
Yes - tarmac is far cheaper and simpler to maintain than block paving.
Maintenance advantages of tarmac
- No weeds growing between joints
- No sinking or dipping areas caused by poorly compacted spots
- No pressure washing needed every season
- No re-sand or re-pointing
- Repairs are fast and low-cost
Maintenance disadvantages of block paving
- Weed growth is common
- Ant nests and shifting sub-bases lead to dips
- Requires regular sweeping, pressure washing and re-sand
- Edge restraints can loosen
- Blocks fade over time
The long-term maintenance spend on block paving is significantly higher.
Is tarmac or block paving more durable?
Both materials are durable when installed properly, but tarmac often performs better in heavy-use areas.
Tarmac durability
- Flexible surface - resists cracking
- Handles vehicle traffic well
- Ideal for domestic driveways, commercial yards and private roads
- 15-25+ year lifespan
Block paving durability
- Strong material but individual blocks can loosen
- More vulnerable to dips, movement and weeds
- Good when maintained properly but higher upkeep needed
For most domestic houses, tarmac provides a stronger, more consistent surface with fewer problems over time.
What looks better: tarmac or block paving?
This is subjective, but most people choose block paving for aesthetic reasons, not practicality. Block paving offers patterns, colours and decorative borders. Tarmac offers a clean, smooth, modern finish that suits most properties - and edging blocks or kerbs can be added for a premium look without the full cost of a block-paved drive.
If appearance is your priority, block paving may appeal more. If durability and cost matter most, tarmac usually wins.
So, is a tarmac drive cheaper than block paving overall?
In almost all cases, yes - a tarmac drive is cheaper both to install and maintain compared to block paving. It offers exceptional value for money, quick installation, and long-lasting durability.
For homeowners who want a smart, reliable driveway with minimal fuss, tarmac is often the best all-round choice. Block paving is ideal when decorative designs or premium aesthetics are the priority, but it comes at a higher cost and requires ongoing maintenance.
