Gravel grids are a protective layer that can be installed on your driveway or other paved surfaces. They act as an extra layer of protection and a cushion for any weight on the driveway.
Gravel grids are usually made up of large pieces of gravel that have been compacted with sand and water, which creates a seamless surface for vehicles to drive over. The size of the gravel grid will depend on how much space you want to cover and how many layers you want in your system.
If you have a large parking area with plenty of cars coming and going, then you may need to get a larger size, so it doesn’t wear out too quickly. On the other hand, if your driveway is small or there’s not much traffic on it at all, then one layer will suffice.
The best size for driveway gravel that you can install is 20mm angular gravel, which is available in most stores, such as Ecodeck.
