Since your feet are always in contact with the pavers you choose for your garden, it’s important to make the right choice! There are plenty of options available for your outdoor paving project, with a range of materials to suit your style and budget.
Sandstone
Sandstone is easier to cut than most stones, but it is also durable enough for any patio. It can be purchased in a range of colours to match the style of your home and it is often cheaper than other options.
Gravel
Gravel is a good option for those on a tight budget. To make this material work, you will need to lay edging so that the stones are kept on the path. Be sure to line the base so that you can avoid future weed problems, and choose gravel with sharp, angled edges, as these will fit together and shift around less easily compared to smooth, rounded stones.
Slate
Slate stands out dramatically in any garden because of its rich colours. The dark, earthy tones match the outdoor landscape of soil, rocks, trees and foliage. Slate is very slip-resistant and stain-resistant, so it makes for a very practical paving choice. If you’re using slate in extremely cold and frosty environments, or around pool areas, make sure to seal your pavers to reduce the risk of them cracking and fracturing.
Granite
This is the strongest and most durable stone. There is basically nothing that will mark this, but that also makes it expensive and difficult to work with. However, a granite path will look fantastic.
