How tarmac is laid
If you’re considering new tarmac for your property, it is really a job for professionals. The level of skill involved is quite large, coupled with the expense of getting all the right machinery and equipment and knowing how to use it all. Here’s how to get a good job for your tarmac needs:
Although tarmac is cheap, probably the most cost-effective available hardstanding, it still only works out economical if you tarmacking a quite big area. The costs increase especially for all the machinery involved and getting it on site. It can be worth considering clubbing together with the neighbours who might benefit from a new surface as well. This will make the job easier and cheaper for contractors who can pass their savings onto you. For information on Tarmac Bath, visit a site like Thornbury Surfacing, a supplier of Tarmac Bath.
When it comes to laying tarmac on the drive, there are several layers involved. The first layer is the foundation. A normal driveway will need excavation downwards to approximately 18cm. Following this, a sub-base layer of crushed hardcore will be placed. Then it is rolled by rollers.
Tarmac is laid in two layers, a base and then the upper surface known as ‘wearing’. Base layers consist mostly of aggregates delivered in a heated truck and once laid, the tarmac can be spread on and levelled with a rake. Back comes the roller to compact all the layers together, and it will continue until there are no visible signs on the surface.
