Pros and cons of using tarmac
Budget savvy property owners often use tarmac due to its relatively low cost to lay – depending on the driveway tarmac thickness. However, it doesn’t drain as well during heavy rainfall, so can cause surface water build-up and localised flooding. Tarmac is also easy to maintain over the long term, with the only damage being occasional moss growth that can easily be prevented with weed killer. However, the material does look a lot “harder” due to the colour usually being dark grey or black. So it’s not necessarily a pretty look.
Pros and cons of using gravel
The gaps in the surface mean that gravel can drain a lot quicker and better than tarmac, so it has a lower potential for causing flooding and resulting damage. While it is also relatively cheap, its nature means that particles can easily be displaced, thus altering the shape and neatness over time. Gravel can also become strewn over adjacent lawn areas, causing a mess. So there will be a higher maintenance cost as you continually have to top up the particles.
Also, don’t forget that gravel can be painful to walk over when you’re barefoot – for example in the summer, or when putting the bins out.
In general, tarmac and gravel are of a similar cost to install, but tarmac is easier to maintain. Often, the final choice might be to do with the property’s overall setting. For example, tarmac and block paved drives fit better into a greyer urban environment, while gravel better complements a rural location.
