When planning and installing a new driveway, knowing which surface to choose can be difficult. There are several factors to consider, such as style, finish, price, durability and ease of installation.
In this guide, we compare block paving and tarmac to help you decide which is the best option for you.
Pros and cons of block paving driveways
Here are a few things to consider if you're thinking about going for a block paving driveway.
Pros
Versatility
One of the main reasons for the popularity of block paving is the versatility it offers when it comes to aesthetics. There are many different types of paving blocks available, ranging from black block paving to brindle block paving.
These paving blocks can be laid in a wide variety of patterns, meaning it's fairly straightforward to find a look that will complement most driveways and homes.
Also, if you're looking for a driveway that works well with a specific garden colour scheme, then block paving will give you lots of choices in terms of block colours. Circle designs are a popular choice for block paved driveways. Bringing curves into your space can make it feel less rigid.
Hard-wearing and long-lasting
Another benefit of choosing block paving for your new driveway is that it tends to be more resilient and lasts longer than a tarmac driveway, even in poor weather conditions. Concrete block paving is manufactured to be tough and can withstand heavy loads such as large vehicles and multiple cars.
Maintenance
Block paving driveways are also fairly easy to repair, meaning that maintenance is usually simpler than it is for tarmac driveways and other surfaces.
If any paving blocks come loose or get damaged, they can be lifted and either replaced or relaid. When done properly, you shouldn't be able to tell that a repair has taken place.
Cons
Price
One of the main downsides of block paving is that it can be more expensive than driveway tarmac. However, it still remains a mid-range price product when considering all driveway options.
Installation
Depending on the design and layout of your new driveway, block paving can take longer to install than tarmac, and the process can be a bit tricky. As you’ll see further down, the sub-base is very important and you shouldn't cut corners when it comes to this. However, the installation process should not be difficult with a professional installer.
If you’re on a strict budget, choosing a less complex design will help to reduce the installation time.
Pros and cons of tarmac driveways
If you're thinking of opting for a tarmac driveway, here's everything you need to know.
Pros
Price
A tarmac or tarmacadam driveway will almost always be cheaper than a driveway made using block paving. The difference in price is because tarmac is a cheaper material and is often easier to install than block paving.
Tarmac driveways usually take around one day to install compared to block paving in the same-sized driveway which can take several days. This reduces labour costs, bringing the overall costs down significantly.
Installation
As discussed, tarmac driveways are quicker and easier to install than block paving driveways, meaning your driveway will be out of use for a lot less time.
Cons
Longevity
Although tarmac driveways are often described as durable, they don't typically last as long as block paving ones. They are still very durable. Although they can develop cracks or puddles over time, this is usually due in part to improper installation and poor base preparation. If you’re set on having a tarmac driveway, make sure you use a professional who comes recommended.
Manoeuvrability
If you have a really small driveway or one that has an unusual shape, it can be very difficult to lay asphalt. This is because tarmac installation requires the use of several machines that won't be able to operate properly in a very small, restricted space.
Lack of versatility
As tarmac consists of broken stone and tar, it is often dark-coloured by nature and tends to offer fewer options in terms of aesthetics. Although you can use a coloured tarmac for your driveway, this may increase the cost.
FAQs
What is the most popular type of driveway material?
The most popular type of material for driveways is concrete. This is mainly due to its durability and the lack of maintenance that it requires. Once it's installed, you won't have to give it much thought, and it falls into the medium price range.
How long do block paving driveways last?
If block paving driveways are properly installed and the base is correctly prepared, you can expect them to last for around 25 years. Block paving is a highly durable surface which is one of the reasons for its popularity.
How frequently should I seal block paving?
If applied properly, block paving sealant should last for around 2 years. Always make sure you use a high-quality product, and if you notice the sealant fading, simply apply a new coat.
Why is a good sub-base important?
Whether you choose a block paving driveway or a tarmac driveway, the first and most important step is to ensure you start off with a good base.
Before laying a new driveway, you need to make sure you've properly considered drainage. You also need to ensure that a good sub-base has been put down. The surface onto which the top layer will be laid needs to be level.
If this isn't done correctly, then your finished driveway is unlikely to be hard-wearing or long-lasting - regardless of whether you choose tarmac or block paving.
Which driveway is right for me?
Both block paving and tarmac have several pros and cons, meaning either of them could be a good choice for your driveway. If you're looking for a cheaper option, then tarmac is the way to go. But if you want something that will last for a very long time and have more style to it, then paving blocks are the better choice.
