Tarmac vs Block Paving Driveways UK Comparison Guide for Homeowners

Choosing a driveway Driveways surface is one of those home improvement decisions that feels simple until the details appear. Cost, drainage, kerb appeal, repairs, planning rules and long-term upkeep all matter. For many UK homeowners, the choice comes down to two popular options: tarmac and block paving.

Both can look smart and perform well when installed properly. The best choice depends on the property, the budget, how the driveway will be used and the look you want to achieve.

Sale Fencing & Surfacing has installed driveways across Sale, Altrincham, Hale, Timperley and Trafford for many years, so this guide takes a practical view of how both surfaces perform in real UK homes.

A smooth tarmac driveway gives a clean, practical finish for everyday parking.

What is a tarmac driveway?

A tarmac driveway is made using a bituminous surface, usually laid over a compacted sub-base. It creates a smooth, dark finish that is commonly used for roads, paths, forecourts and residential driveways.

Tarmac suits larger areas because it can be laid quickly and gives a continuous surface with few joints. It is often chosen for practical family driveways, rental properties and homes where a clean, simple finish is preferred.

What is a block paving driveway?

Block paving uses individual concrete or clay blocks laid in a chosen pattern over a prepared base. The joints are filled with kiln-dried sand, and the blocks interlock to form a strong surface.

Block paving is popular because it offers more design choice. Homeowners can select different colours, shapes, borders and patterns to suit the style of the property.

At Sale Fencing & Surfacing we've installed hundreds of driveways across Sale, Altrincham, Hale, Timperley and Trafford.

One thing we've learned is that homeowners often focus on the surface, when the most important part is actually the groundwork underneath.

A properly excavated driveway with a well-compacted MOT Type 1 sub-base and good drainage will usually outlast one where shortcuts have been taken, regardless of whether the finish is tarmac or block paving.

If budget is the priority, we often recommend tarmac for larger driveways because it offers excellent value.

If appearance and long-term flexibility are more important, block paving is usually worth the additional investment because individual blocks can be replaced without resurfacing the whole driveway.

Installation methods and what good workmanship looks like

A driveway is only as good as the preparation beneath it. Many driveway failures come from poor excavation, a weak sub-base or bad drainage rather than the surface itself.

How tarmac is installed

A typical tarmac driveway installation includes:

• Excavating the existing surface to the right depth

• Installing a strong, compacted sub-base

• Adding edging restraints where needed

• Laying a base course if required

• Applying the wearing course of tarmac

• Compacting the surface while it is hot

  
  

The surface needs proper falls so water can drain away from the house. Edging is also important, as tarmac can break down at the sides if it is not restrained.

Tarmac should not be treated like a thin coating over old ground. If the base is weak, the surface may dip, crack or rut under parked vehicles.

How block paving is installed

A typical block paving installation includes:

• Excavating the driveway area

• Laying and compacting a suitable sub-base

• Installing edge restraints

• Adding a sharp sand laying course

• Laying blocks in the chosen pattern

• Cutting blocks neatly around edges and features

• Brushing kiln-dried sand into the joints

• Compacting the finished surface

  
  

The jointing sand helps lock the blocks together. If the edging is poor, the blocks can spread. If the base is uneven, dips can appear.

For driveways, herringbone patterns are popular because they handle vehicle movement well. Stretcher bond and basketweave can look attractive, but the right pattern depends on the layout and use.

Block paving takes longer to install but gives more choice in pattern and detail.

Costs for tarmac and block paving in the UK

Driveway prices vary by region, access, excavation depth, waste removal, drainage requirements and the quality of materials. The cheapest quote is rarely the best if it skips groundwork.

As a broad guide, tarmac is often more cost-effective for larger driveways, while block paving usually costs more because it takes longer to lay and uses more individual materials.

What affects the cost?

The main cost factors include:

• Size of the driveway

• Existing surface removal

• Depth and condition of the ground

• Drainage work

• Edging, kerbs and borders

• Manhole covers and service covers

• Shape and access

• Choice of blocks or finish

• Waste disposal

  
  

A small block paved driveway with decorative borders may cost more than a plain tarmac driveway of the same size. A large tarmac driveway may offer better value than paving the same area block by block.

That said, price should not be judged only at installation. Repairs, cleaning and long-term appearance also affect value.

Maintenance and cleaning

Maintaining tarmac

Tarmac is fairly low maintenance. Regular sweeping and the occasional wash usually keep it looking tidy.

The main maintenance tasks are:

• Remove leaves, moss and debris

• Treat oil spills quickly

• Avoid turning car wheels while stationary, especially on hot days

• Watch for cracks or worn edges

• Consider resealing when the surface starts to fade or dry out

  
  

Oil can soften or stain tarmac. Heavy loads, sharp stands and repeated pressure in one place may also mark the surface.

Maintaining block paving

Block paving needs more hands-on care. The surface itself is strong, but the joints need attention.

Common maintenance tasks include:

• Sweep regularly

• Remove weeds from joints

• Top up kiln-dried sand after cleaning

• Treat moss and algae where needed

• Pressure wash carefully, avoiding too much joint sand loss

• Re-level sunken blocks if movement appears

  
  

Block paving can look excellent for many years, but neglected joints can allow weeds and movement. Sealing can help reduce staining and weed growth, though it is not essential for every driveway.

Durability and lifespan

Both materials can last well when installed correctly.

Tarmac is flexible, which helps it cope with normal vehicle use and small ground movements. It is widely used on roads for a reason. On a domestic driveway, a good tarmac surface can last many years, especially when the base is sound and water does not sit on it.

Block paving is also very durable. Because each block is separate, the surface can tolerate movement without cracking in the same way a single slab might. If one area sinks, it can often be lifted, the base corrected and the blocks relaid.

The key difference is how ageing appears. Tarmac may fade from deep black to grey and can show patches. Block paving may lose joint sand, develop weeds or shift in areas, but individual repairs can blend in more easily.

Drainage and planning considerations

Drainage is a major issue for UK driveways. Front gardens being paved over can increase surface water run-off, which is why planning rules matter.

In England, if you are creating or replacing a front garden driveway using an impermeable surface over more than 5 square metres, you generally need to make sure water drains to a permeable area within the property, such as a lawn, border or soakaway. If water will run onto the public highway or into drains without a compliant system, planning permission may be required.

This is general guidance, so check with your local council before work starts.

Drainage with tarmac

Standard tarmac is usually impermeable. That means the driveway must be laid with the correct fall towards a suitable drainage point.

Options may include:

• Channel drains

• Soakaways

• Drainage to a lawn or planted border

• Permeable tarmac systems where suitable

  
  

The design must keep water away from the house and avoid sending it onto the pavement or road.

Drainage with block paving

Block paving can be installed as a standard impermeable surface with drainage channels, or as a permeable system.

Permeable block paving uses specially designed blocks, wider joints and a suitable sub-base that stores and filters water. It can be a good option for front gardens where Sustainable Drainage Systems, known as SuDS, are needed.

Good drainage protects the driveway, the house and the pavement outside.

Repairs and common problems

Tarmac repairs

Tarmac can be repaired if cracks, potholes or damaged edges appear. Small areas can be patched, and larger areas can sometimes be resurfaced.

The main drawback is appearance. A new patch may not match the older surface, especially if the driveway has faded. This does not always matter on a practical driveway, but it can be noticeable near the front of a house.

Common tarmac problems include:

• Cracking

• Potholes

• Faded colour

• Softening from oil or fuel

• Edge breakdown

• Low spots where water collects

  
  

Block paving repairs

Block paving is easier to repair neatly. Damaged or stained blocks can be removed and replaced. Sunken areas can be lifted and relaid after correcting the base.

This makes block paving a strong choice where access to underground services may be needed. If a pipe or cable needs attention, the blocks can be taken up and reinstated.

Common block paving problems include:

• Weed growth in joints

• Sinking or spreading

• Loss of jointing sand

• Staining

• Moss and algae

• Uneven edges if restraints fail

  
  

Appearance and kerb appeal

Here, block paving usually has the advantage. It offers more choice in colour, pattern and edging. A well-designed block paved driveway can lift the look of a property, especially when matched with walls, fencing, planting and the house style.

Tarmac has a simpler look. It can still be smart, especially with a block paved border or kerb edging. Many homeowners choose a tarmac centre with decorative edging to balance cost and appearance.

Best appearance options

Tarmac vs Block Paving Driveways for a modern detached home, a smooth tarmac drive with clean edging can look sharp and uncluttered.

For a period property, block paving in softer tones may suit the character better.

For a family semi-detached home, either option can work. The decision often comes down to parking needs, budget and how decorative the frontage should be.

Which driveway is best for different property types?

Terraced houses

Space is often limited, so detail matters. Block paving can make a small frontage look more considered. If the area is tight, choose a simple pattern and avoid too many colours.

Tarmac can work well if the priority is budget and easy parking.

Semi-detached homes

Both surfaces suit semi-detached homes. Tarmac is practical for two-car driveways and frequent use. Block paving adds kerb appeal and works well with borders, paths and front steps.

A mixed design can be ideal, with tarmac for the main parking area and block paving around the edges.

Detached homes

Larger detached properties often benefit from tarmac because of scale and cost. Long drives, turning areas and multiple parking spaces can become expensive with block paving.

Block paving may still be the better choice near the entrance or house frontage, where appearance matters most.

New-build homes

Block paving is common on new-build estates because it looks neat and can be designed for drainage. Tarmac may suit larger plots or shared access areas.

Rental properties

Tarmac is often a sensible choice for rental homes because it is practical, clean and relatively low maintenance. Block paving may look better, but landlords should factor in weed control and joint maintenance.

Combining tarmac with block paving can give a practical surface with a smarter edge.

Practical advice before choosing

Before asking for quotes, think about how the driveway will be used day to day.

Ask these questions:

• How many cars will park on it?

• Will vans or heavy vehicles use it?

• Does water currently pool anywhere?

• Is the front garden higher or lower than the pavement?

• Do you want a decorative finish or a simple one?

• How much maintenance are you willing to do?

• Will the driveway need access to drains or underground services?

• Does the house style suit a traditional or modern finish?

  
  

Also check the contractor’s preparation details. A good quote should explain the excavation, sub-base, drainage, edging and surface finish. Vague quotes can lead to shortcuts.

FAQs

Is tarmac cheaper than block paving?

Tarmac is often cheaper, especially for larger driveways. Block paving usually costs more because each block is laid by hand and the design can be more detailed.

Which lasts longer, tarmac or block paving?

Both can last for many years with good installation. Block paving can have a longer service life because individual blocks can be repaired or replaced. Tarmac also lasts well but may need resurfacing or patching as it ages.

Is block paving better for drainage?

It can be. Permeable block paving is designed to let water pass through the surface into a suitable sub-base. Standard block paving still needs proper drainage, just like tarmac.

Does tarmac need much maintenance?

Tarmac is relatively low maintenance. It should be kept clean, protected from oil spills and checked for cracks or edge damage.

Which driveway adds more kerb appeal?

Block paving usually adds more kerb appeal because it offers more colours, patterns and borders. Tarmac can still look smart, especially with quality edging.

Tarmac vs Block Paving Driveways

The best choice depends on priorities

Tarmac is the better choice if you want a practical, cost-effective driveway with a clean finish, especially for larger areas or heavy everyday use.

Block paving is the better choice if appearance, repair flexibility and design choice matter more. It suits homes where the driveway forms a key part of the frontage.

For many UK homeowners, the best answer is not purely one or the other. A well-built tarmac driveway with block paved edging can offer a strong balance of price, durability and kerb appeal. A fully block paved driveway can be worth the extra cost when the look of the property is the main concern.

The right surface starts with good groundwork, proper drainage and a design that suits the home. Get those basics right, and both tarmac and block paving can serve a driveway well for many years.

During every quotation we look at:

• parking requirements

• budget

• drainage

• existing levels

• planning considerations

• appearance

• maintenance expectations

We then recommend the option that best suits the property rather than trying to sell one particular surface.
