The key to a successful driveway installation lies firmly with the ground preparation, indeed, a majority of inferior driveways results are because the ground was not correctly prepared. Every platform requires a solid foundation, especially one that will bear the weight of a few cars, and regardless of the material you use, there must be adequate drainage.
Ground Preparation
To do the job properly, you need to excavate at least 8 inches, perhaps even as much as 1ft, and the best driveways in Leeds would all have solid base on which to build. The range of materials includes the following:
- Tarmac
- Block Paving
- Stone Paving
- Poured Concrete
Layer of Hardcore
Ideally, the ground would be rolled with heavy machinery, before adding a layer of hardcore, which is also rolled into place. Leaving 3-4 inches for the final surface, sand or gravel would be the next layer, and then the final finishing material can be applied.
Block Paving
The block are installed on top of a sand and cement bed, which is then watered, causing it to harden, and as the blocks are square shaped, they are very durable and can withstand heavy loads. There would be adequate drainage, as the blocks are semi-permeable, allowing rainwater to drain away naturally.
Tarmac
The tarmac is laid on top of the hardcore base, and should be at least 4 inches thick, which will ensure a solid surface. Resurfacing a tarmac drive is unwise if you don’t remove the existing tarmac, and it won’t be long before weeds emerge.
When watching a professional team at work, you will notice how much time they spend on ground preparation, which is a sign that the job is being done properly.
