Tarmac (tarmacadam) is an extremely dark, bituminous material that needs to be laid as a hot liquid and subsequently leveled and compacted to form the right shape and gradient for your driveway. In a few hours it then must be allowed to cool, during which time the particles bind to form a solid, hard-wearing surface.
Benefits of laying a tarmac driveway
It may not be the most attractive or elegant looking option, but there are a number of benefits to laying a tarmac driveway;
Easy to install: Unlike paved or concrete driveways, tarmac usually can be laid directly onto any existing surface whereas the other materials require a full depth bedding layer before work can even begin, although if you have a lawn this will need to be removed beforehand.
Very quick to lay: A professional driveway installer will mix the tarmac at a high temperature in a proper paving machine and usually get the job done in a matter of hours – which means less disruption for you and any other road or path users who might be affected.
Long lasting and incredibly strong and durable: Tarmac is particularly resilient to the weight of heavy vehicles or traffic flow that can otherwise crack or cause breaks in paving and concrete.
Impermeable: Tamac is resistant against any significant water damage that can cause a front lawn to flood – involving a long clean-up job afterwards.
Cheap and easy to maintain: Any scratches or dents can be quickly repaired by you or a professional with the correct polish, and even if your driveway suffers extensively you can add a new tarmac layer directly onto the old one – saving you the worry of excavation costs!
Easy to edge with other materials: Clay tiles, stone or brickwork, for a neat and attractive finish to your driveway.
Weather resistant: Come rain or shine, your tarmac driveway will stay looking as good as new for many years to come!
An overlay is a tarmac layer applied over a pre-existing driveway, generally a worn-out tarmac driveway which may be structurally solid but is probably in need of an upgrade.
This approach is only feasible if the following applies:
- The additional covering won’t impact the damp course or house’s wall vents
- The foundation under below the current driveway hasn’t sunk
- There are no cracks in the base – these will get bigger and eventually transmit to the new surface
- All potholes are fixed to a depth of 300mm first
Overlays are not only faster to install they are also much cheaper. No extra base, sub-base or binding course is required. All minor repairs are done first and after that, a primer is sprayed prior to a 30-40 mm fine tarmac layer is applied and rolled.
Overlays aren’t suitable for all driveways, therefore it is important to get a professional opinion before proceeding.
How much to tarmac a drive?
The cost of a tarmac driveway per square meter (m2) will depend on the size and shape of the area, but to avoid ‘cowboy builders’ and a poor job you should always be prepared to pay at least between £45–£60 per square meter.
In general you should expect to pay more:
- If the area is too small
- If the job is too small
- For irregular shapes
- Poor access
- Unusual slopes
- For red coloured tarmac
Anything lower than £40 per m2 is likely to be made of an unauthorized mixture that is sure to come apart in a matter of months.
To get the best value for money make sure you shop around and compare a number of different tarmac driveway quotes before you settle on a driveway contractor and try to include a guarantee into the final contract as well. As long as you’re careful, your new tarmac driveway could be planned and completed in a matter of weeks.

What should be included in a driveway work schedule?
The job should include all the materials, labor and waste disposal elements for the tarmac driveway project. More precisely the driveway company/contractors include in the work schedule the following:
- Remove existing driveway.
- Repair existing or create new tarmac base (if it is damaged or insufficient for a new tarmac).
- Lay weed control membrane.
- Connect drainage to existing pipework.
- Lay sub base/base.
- Lay concrete sand edging.
- Lay 1st and 2nd tarmac course by machine or hand and then make it compact with a roller.
- Remove and dispose all waste material.
- Clean and tidy the site.
If you choose to reduce the cost but compromise on the quality, you could lay a single tarmac layer on the existing one, provided that it is in good condition. In this case, a bonding layer is first applied before the tarmac is applied and then rolled. Also, the existing drainage is raised to the correct position.
Do you need to resurface or replace your tarmac?
Since it is only good for around 20 years and demands frequent maintenance just about every 3-5 years, property owners have to also think about what services they have carried out consistently to be able to preserve the strength and effectiveness of an tarmac driveway or some other paved area. Over the lifespan of your property, this means deciding between a complete driveway replacement and resurfacing, with the second option being significantly less costly.
Tarmac driveways replacement is required if the current surface is in disrepair or the underlying gravel foundation exhibits evidence of deteriorating. Getting rid of and replacing a tarmac can also be required when the correct drainage of the driveway is not attained given that the surface is too flat. When your foundation continues to be solid, you can easily fix cracks and add strength to the surface by just placing a brand new coating over the old layer to resurface the current surface.

How long does it take to tarmac a drive?
Requirements: The time needed to excavate an area and then lay a tarmac driveway depends mostly on the shape, size of the driveway, drainage and edging.
Trees, shrubs & tree roots : If there are any trees, shrubs or tree roots, this makes the job more difficult so it will take more time to complete.
Weather conditions: Rainy and snow weather can also affect the time needed, as it makes it difficult for contractors lay the tarmac, especially when it is pouring.
Number of workers : One other important factor is the number of workers on the project as if only one is working on it, the time doubles. As a general guide, a 30 square meter (m2) rectangular driveway should take a couple of days. The first two days the contractor will work on excavating, installation of sub-base, edgings and drainage and on the third day on tarmacking and completing the job.
If you are a looking for a quick solution, then the best solution probably is to lay a new layer on an existing one. Repairs usually take an hour or two as the tarmac has to be warm otherwise the material becomes unworkable. The worker starts by lifting and securing the drainage channel and then works on the tarmac.
Cost of tarmac vs. concrete driveways
Cost is an important consideration when installing a driveway in your home. Of course, there are a lot of pros and cons when choosing between concrete or tarmac and we will go over these next, but in cost terms an tarmac driveway is much better value for money. In general terms a tarmac driveway costs between £3- £5 per square foot whilst a concrete driveway ranges between £4 and £15.
Tarmac vs. concrete driveways
Tarmac and concrete are the two most commonly found driveway materials, and apart from cost there are other important factors to consider above and beyond cost..
Firstly, in terms of ease of repair, resurfacing and general maintenance tarmac driveways are far superior toconcrete. Weathering is another important consideration: Clearing ice or snow from an tarmac driveway is much easier than from a concrete one. Tarmac will not crack during the winter, whilst this is a known risk with concrete. Tarmac drives are much faster to intall too – once the tarmac has been poured it will cool and harden in between 5-8 hours, whilst concrete takes several days to cure.
However, concrete driveways also have their good points.
Concrete is incredibly durable and can easily last over 40 years, compared to this apshalt will probably need replacing at around 20-30 years. Concrete driveways do not need to be sealed which means that over the course of its lifetime concrete ultimate costs you less. You can also choose from various driveway designs if you choose concrete.
Tarmac paving cost factors
Costs are always a key factor and the size of your driveway and how much labour is needed to install it will drive the price of your new tarmasc drive. Other factors can also cause costs to increase.
Driveway size: Tarmac is charged for by the square foot, therefore the larger your driveway is the more it will cost, simply because of the amount of tarmac it will need. The smaller the driveway, the lower the cost.
Initial installation: If this is the first time a driveway has been installed the ground will need some preparation and this will add to the timeline and the costs. Laying tarmac over an existing tarmac drive will lessen cost.
Permits: Be aware that you may need to apply for permits from your local authority. Things like excavations, removing trees and so on. You should check your local rules beforehand as these can effect the cost of your project.
Drainage: There will need to be proper drainage. If this is not already in place in could add up to £1000 to the cost of your tarmac drive
Coats: You can choose to add as many coats of tarmac as you want to, although this will add to the cost, you can also choose colored topcoats and even stamped to make your driveway more original.
Labour costs: Local contractors often have different rates so it is worthwhile shopping around. Be aware that more experienced contractors will charge more as will those who travel from outside your area. It is important to remember to offset considerations of costs with considerations of quality.
