Driveways aren’t just practical aspects of a home, providing somewhere to keep cars off the road and close at hand – they also form an important part of a property’s overall curb appeal. As such, everything from size to drainage needs needs to be considered if the space will do justice to your home’s exterior.
In the case of my own drive, I chose Driveway material Purely for their aesthetics – the buff-coloured Cotswold stone gravel seemed to fit in nicely with our cottage as well as its rural setting. I had no idea how difficult it would be to keep this gravel in place. As it is, it somehow ends up on the pavement and out into the road – which looks really messy if not dealt with regularly.
While sweeping it back provides a temporary fix, I’m really curious to find out where we went wrong in the first place and if there’s a fix we can implement now. I reached out to the experts for their top tips on keeping gravel in place on a driveway, and they offered five effective solutions to the problem.
1. You need to start with a good sub-base
This first step is really important – in fact, the success of any driveway, no matter what material it’s finished with, depends on proper preliminary prep work. In fact, one of the biggest Driveway mistakes is to fail to give sufficient consideration to establish a proper sub-basis.
When it comes to gravel driveways, you want to create a stable, well-compacted base, at least 100-150mm deep, using Type 1 aggregate or crushed stone. This will act to support the gravel you put down later and help prevent it from moving around too much.
The experts I spoke to were also keen to point out that it is also wise to put a separation membrane between the foundation and the gravel – especially in wet weather – to prevent mixing of gravel and soil.
2. Gravel shape matters more than you think
I have to admit, I gave little thought to the shape of my gravel – I just liked the creamy color. However, obviously, if I had, I would no longer be locked in a constant battle to keep it in place.
Guy Wall, Head of Marketing GCL Products Explains why shape is important. “Angular gravel locks together better, unlike rounded pea gravel. Imagine a scrabble bag that you put a handful of rocks in and try to manipulate them and move them around in your hand through the bag. Angular gravel locks together and it’s relatively difficult to get much movement out of it. Now imagine it’s filled with marble and the resulting piece is out of round shape. On your driveway. This is the same for stones and angular gravel wants to roll.”
and yours Consider a gravel driveway Shouldn’t just come down to shape – according to the cow size also plays a part. “Size is important, because finer grades of gravel can easily get stuck in tire treads or, if you have very fine gravel, even shoe treads.
“If you have a gravel grid, go too big with your gravel and you’ll find that the stones can break through the inner walls on the grid,” Guy continues. “We generally recommend using a grade that is properly scaled to the dimensions of the cell. For example X-Grid from GCLRound cells are 55mm in diameter, so we recommend larger diameter stones than 20mm. This means that any two pieces of stone should fit easily next to each other without causing tension or stress on the cell walls.”
Guy has some interest and experience in sustainable drainage, gardens and landscaping as well as solar and renewable technologies. Resin bound gravel, wet pore rubber surfacing and permeable surfacing are their specialties.
3. It is important to use the right height edge
When we first Turned our front garden into a drivewayWe have incorporated edging into the design of the driveway. Between the drive and the pavement, we used a slightly raised brick edge, which we thought would hold the gravel in place – and for a while, it did.
However, we had completed the driveway before we started the house extension and renovation, which resulted in a barrage of delivery lorries that not only managed to knock over our newly installed gate post, but, due to their weight, sank the curb we had placed on it.
It needs a rebuild now because how well this gravel is incorporated will make a big difference, but this time we will pay more attention to its design, especially its height. After talking to the experts, it should sit just above the top of the gravel, but not so high that it becomes a trip hazard.
4. Consider the depth of the gravel
Again, not an element Driveway Design That I overthought – I just assumed I would need enough gravel to cover the base instead of researching the recommended depths.
“Loose gravel drives are great. They’re natural, help reduce hydrocarbons as a source control measure, and come in so many different colors, grades and shapes that you can easily find one that perfectly meets your needs,” prefers Guy Wall. “However, unfortunately, it’s not just a case of digging a hole and filling it with gravel.
“Depending on the depth of your gravel, you may find that the gravel wants to break out of its confines and take the house elsewhere,” Guy continues. “Certain depths can actually cause your car to ‘beach’, where the underside of the vehicle either partially or fully rests on the surface and the tires can’t get traction, meaning you’ll need to reach for the shovel.”
Obviously, when making changes to tame my gravel, I should aim for a depth of between 40-50mm.
5. A gravel grid is the perfect way to keep everything in place
I wish I had realized how effective the gravel grid is at keeping everything in place. I checked How to Lay a Gravel Driveway Installed one properly and off, things will look very different outside my house now.
“Gravel grids are a relatively new but highly efficient invention. Their sole purpose is to retain the gravel, prevent migration and provide some strength and stability to the surface,” explains Guy Wall. “By locking a small amount of stone within the grid cells, the pockets effectively trap the gravel and prevent it from migrating to other nearby areas.
“Different grids can have different shapes or patterns and come in different shapes, sizes and weight tolerances,” Guy continues. “In 99% of cases, using any gravel grid is better than using none on a vehicle-traffic surface, however, not all grid products are manufactured or designed equally.”
Given that we plan to make some significant changes to our driveway in the coming year to give our home one Exterior makeover And makes it possible to get another car by applying Curb planning permission waivedI’m keen to use a grid this time around – so I asked Guy what I should look out for when choosing one.
“One of the most important things to consider is: Is it built for this purpose?” The cow starts. “We’ve seen a lot of products used that weren’t designed for gravel retention and other uses like pond safety grids. These usually have large diamond-shaped cells in the body of the grid and, to be honest, they don’t work particularly well. The cell size was too large, the plastic was too thin and low quality, so it’s still not Migrade rated.”
Instead, Guy suggests something like X-Grid from GCL Products, which is made from a specially formulated polymer to make it very stiff and durable, and also flexes enough to withstand heavy loads on surfaces that may not be perfectly flat.
“The cells are a combination of asymmetrical shapes and rounded columns that help to deflect vertical loading pressures from the side, meaning they have load-bearing certificates of 428 tonnes of vertical load per square metre, even before they are filled,” adds Guy.
