When it comes to upgrading your driveway, two popular choices often top the list: tarmac and block paving. Both options offer their own set of advantages, and your final decision will depend on a mix of budget, style, and functionality.
To help you choose wisely, we’ll compare tarmac and block paving side by side, covering everything from appearance to maintenance.
What Is Tarmac?
Tarmac, short for tarmacadam, is a smooth black surface made from crushed stone mixed with tar. It’s one of the most common materials used for driveways in the UK thanks to its quick installation and long-lasting durability.
What Is Block Paving?
Block paving uses small bricks or blocks, typically made of concrete or clay, laid out in a variety of patterns. The result is a decorative and hard-wearing surface that’s suitable for driveways, patios, and paths.
Cost Comparison
Tarmac: More Budget-Friendly
If you’re working within a tight budget, tarmac usually comes out on top. It requires fewer materials and less labour time than block paving, which means a lower overall cost. It’s especially cost-effective for larger areas.
Block Paving: Higher Upfront Cost
Block paving tends to be more expensive due to the detail involved in laying each individual block. The materials also cost more. However, it can add more value to your property due to its decorative appeal.
Aesthetic Appeal
Block Paving: Customisable and Stylish
One of the biggest draws of block paving is its visual appeal. With a wide choice of colours, shapes, and patterns, it can be tailored to complement any home. You can also add decorative edging or borders for a bespoke look.
Tarmac: Simple and Clean
Tarmac offers a sleek, no-fuss finish. While it doesn't provide the same design flexibility as block paving, it can still look modern and tidy. For a touch of flair, many homeowners pair tarmac with stone or brick edging.
Installation Time
Tarmac: Quicker Turnaround
Tarmac can be laid and ready to use within a couple of days. That makes it ideal for anyone looking to complete their driveway project quickly.
Block Paving: Takes More Time
Laying a block-paved driveway takes longer due to the need for precision. Each block must be placed by hand, and patterns often require careful planning and alignment.
Durability and Load Handling
Tarmac: Tough and Flexible
Tarmac is strong enough to handle the weight of vehicles and adapts slightly under pressure, reducing the risk of cracking. It's a great option for households with cars, vans, or light trucks.
Block Paving: Hard-Wearing but Prone to Shifting
Block paving can last a long time if laid properly, but it may shift or sink over time, especially under heavy loads. Weeds can also grow in the joints if not maintained regularly.
Maintenance Needs
Tarmac: Low Maintenance
Tarmac requires minimal upkeep. Occasional power washing and sealing every few years will keep it looking fresh and prolong its lifespan.
Block Paving: Higher Maintenance
Block paving needs more regular care. Weeds and moss can appear between the blocks, and shifting or sinking areas might require re-levelling. Joint sand may also need topping up after cleaning.
Weather Resistance
Tarmac: Handles Weather Well
Tarmac is built to endure UK weather. It holds up against rain, frost, and even moderate snow. That said, extreme heat can sometimes cause it to soften.
Block Paving: Drains Naturally
Block paving has natural drainage gaps, which helps reduce surface water. However, excessive rain can cause the sub-base to weaken if not properly installed.
Longevity
Both surfaces can last well over 15 years with the right care. However, their long-term performance depends heavily on the quality of installation and how well they’re maintained.
Repairs and Replacement
Tarmac: Easier to Resurface
Small cracks in tarmac can be filled quickly, and resurfacing the entire area is generally straightforward. It’s also cheaper to repair than block paving.
Block Paving: Easy to Replace Individual Blocks
One big plus of block paving is that you can replace damaged blocks without disturbing the rest of the surface. This makes it cost-effective in cases of minor damage.
Eco-Friendliness
If you’re looking at sustainability, block paving tends to be more eco-friendly. Some systems are permeable, which helps with drainage and reduces the risk of water runoff. Tarmac, while recyclable, is less environmentally friendly in its production.
Best Uses for Each Surface
Choose tarmac if you want a fast, affordable, and long-lasting solution. It's ideal for larger driveways or areas where practicality is the priority.
Go with block paving if style and customisation matter more. It's perfect for homes where curb appeal is a top concern.
Still Can’t Decide? Consider Your Priorities
If you value speed, lower cost, and simple upkeep, tarmac is likely your best bet. Homeowners across the South Coast have seen the long-term value of choosing tarmac driveways in Bournemouth for durable and reliable surfaces.
But if aesthetics and design flexibility are your top priorities, and you don’t mind a bit more maintenance, block paving might suit your needs better.
Final Thoughts
Choosing between tarmac and block paving comes down to how you want your driveway to perform and look over time. Both are excellent options in their own right, but each comes with its own set of pros and cons.
Take the time to weigh your options based on your budget, design preferences, and long-term expectations. With the right choice, your new driveway will serve you well for many years to come.
