Let’s talk about two scenarios that British homeowners are often faced with. The first one is you are building a house, and you would like a gravel driveway to fit with the rural location you live in. The problem is, your drive has a 1:12 slope, making gravel impractical and inadvisable at best.
Concrete and tarmac will change the style of your home, giving it a more suburban look. So what do you do? Do you go with gravel anyway, and live with the consequences?
The second scenario is you install the best gravel for a sloped driveway, which as many in the industry will tell you is #57 gravel. But it is far too loose to drive on. Wheels will spin in the gravel. And you are left wondering if you should have used a different type of gravel? Or some other alternative entirely?
The reality is that gravel is usually impractical for a drive with a slope. Gravel will naturally roll downhill when someone drives over it, as well as whenever it rains. One of the biggest downsides of gravel is that the material shifts over time. It doesn’t stay in one place unless you add stabilisers. But even then, it is a risk.
How Is Gravel Applied?
To understand what is the best gravel for a sloped driveway, we have to look at the application process of gravel. Whenever you apply gravel to your driveway, you use three sizes of gravel. There are three layers, and the first one consists of baseball size rocks, or as people in the industry call them, #3 stones.
The first layer forms a foundation for your driveway, and ensures good drainage. The first layer is usually 4 inch thick.
The second layer is another layer of 3-4 inches golf-ball size rocks. These are the popular #57 rocks we talked earlier as the best gravel for sloped driveway. These rocks form the transition between the top layer and the first layer.
The top layer is actually a layer of marble-size rocks that vary in colour. It all comes down to the type of stone you chose. You will need machine crushed stone for each layer.
Can You Install Gravel On An Inclined Driveway?
This is the question many have. Not just whether there is a preferable type of gravel for a sloped driveway, but can you actually install it in practice. The answer is a resounding yes, but it comes with a set of risks. Here is a quick step by step guide on how to do it:
