Did you know that gravel driveways can last for at least 100 years if properly maintained?

Gravel driveways are a popular choice for homeowners because they offer benefits such as a traditional aesthetic and minimal maintenance. Gravel driveways boast natural drainage due to their permeability. This permeable paving benefits homeowners by removing the need to apply for planning permission when installing a gravel driveway.

The cost of gravel driveways is relatively low compared to that of other driveways, making them a cost-effective choice for homeowners.

A typical plastic grid driveway will cost around £2500.

What Is A Plastic Gravel Driveway Grid?

A plastic grid driveway uses plastic cellular grids that come in a honeycomb structure, designed to keep gravel in place on your driveway. This grid system prevents gravel migration by keeping gravel tightly in place. Recycled plastic versions of these grids are available for the environmentally conscious.

One of the issues associated with traditional gravel driveways is the formation of potholes if the gravel is not looked after. The unstable surface of the gravel driveways can make it difficult to wheel buggies or wheelchairs across the drive. Installing permeable paving grids can solve these problems.

Gravel driveways benefit from natural permeability, which is maintained even when plastic grids are installed. Gravel grid mats prevent rutting and pitting while retaining the porous nature of a gravel driveway. The vast majority of these grids are non-toxic and chemically inert, making them safe for use in your driveway.

Benefits Of Plastic Gravel Grids

Stability

Plastic grids prevent migration by holding the gravel in place. These grids prevent erosion and potholing, meaning your driveway will require less maintenance throughout the year.

Each grid is designed to withstand significant weight so that it won’t break or weaken due to cars or footfall.

Easy To Install

Installation of plastic driveway grids is a speedy and straightforward part of the driveway installation process. Once the first few grids are in place, installing the remaining grids is simple.

Solid

Adding a plastic grid model to your driveway will make it a more stable surface, increasing accessibility. A stable driveway surface allows wheelchairs and buggies to be pushed across the surface with ease, without the risk of the wheels falling into a pothole.

People with mobility issues will benefit from this stable surface because the plastic grids prevent gravel from slipping out from under your feet.

Increased Lifespan

Driveway grids are made of tough plastic, a material that is rot-resistant and has a long lifespan. Having driveway grids in your gravel drive prevents issues associated with gravel driveways, such as gravel erosion and gravel migration. Preventing gravel migration lengthens the lifespan of your driveway with minimal maintenance required and reduces the amount of gravel lost to the road.

Plastic Grid Driveway Price

You can expect to pay between £10-£15 per square metre for grids to keep the gravel in place on your driveway. Your choice of grid colour and the quality of plastic may affect the cost.

Though they add to the cost of your gravel driveway at the outset, driveway grids offer a considerable return on investment. They increase your driveway’s lifespan and minimise the time and money needed for driveway maintenance.

Types Of Gravel

Gravel comes in different forms, with some types being more suitable for use in the sub-base and others for the surface layer. They also vary in texture, shape and colour. The price of each type of gravel is similar. For an 850kg bag of gravel, you can expect to pay on average around £70.  Smaller 20kg bags come in at less than £5 each.

Pea Gravel

Pea gravel, also known as pea shingle, is made up of small stones in various shapes and sizes. Each stone measures 20mm or less, and every individual pebble has a smooth surface. Pea gravel requires edging to keep the stones in place because they don’t lock together like other stone varieties. Pea gravel is relatively cheap, with an 850kg bag costing around £70.

Quarry Stone

Quarry stone is also known as dirty stone, MOT Type 1, and blinding. Quarry stone consists of a mixture of 40mm stones, smaller 10-20mm stones, sand, and dust. It’s a suitable material for use as a sub-base because of its stable surface. An 850kg bag typically comes in at £60.

Crushed Stone

Crushed stone gravel is made up of coarse sand and small stones. Crushed stone can be used as either a sub-base or top layer depending on the ratio of coarse sand to small stones. You can expect to pay £70 for an 850kg bag.

Washed Stone

Washed stone is similar in appearance to crushed stone, but the main difference is that it’s washed, which gives it a shinier finish. The smaller stones are suitable for use in the sub-base, and the larger stones are ideal for use in the top layer. The average cost of an 850kg bag of washed stone is £70.

Blue Grey Slate Chippings

Slate chippings give a unique finish and a touch of colour to your driveway. Because of their trendy look, blue-grey slate chippings are more expensive than other types of gravel. Blue-grey slate chippings cost around £150 for an 850kg bag.

Polished Pebbles

Polished pebbles are pebbles that have been polished by a body of water. They are a popular choice of gravel because of their unique finish and the range of colour options available.

Polished pebbles can be slippery, which means they don’t provide the ideal surface material for a driveway. If you like the aesthetic of polished pebbles and you want to incorporate their use in your gravel driveway, consider using them as edging material. This way, you can create an attractive border for a more stable variety of gravel.

Because of their unique look, polished pebbles cost more than other types of gravel. An 850kg bag of polished pebbles will set you back around £300.

Stone Dust

Stone dust is similar to very coarse sand. It is typically used as a binding agent for the sub-base or the top layer and can be used by itself or in a mixture with small and large stones. The average cost of an 850kg bag of stone dust is £70.

Marble Chips

Marble chips can provide your driveway with a unique and stylish finish. Marble chips tend to migrate more than other types of gravel, hence the importance of having your gravel driveway installed with plastic grids beneath the top layer. Installing edging is another way to keep these chips in place.

Marble chips are more expensive than the average type of gravel, coming in at £145 for an 850kg bag.

FAQs

How are plastic grids installed?

Installing plastic driveway grids is a simple part of the gravel driveway installation process. Once the ground of the driveway area has been excavated, and the sub-base has been installed, you can lay the grids to hold the gravel in place. The grids should be applied across the whole driveway in an interlocking pattern.

Once the grids have been installed, you can lay your top layer of gravel, filling all the grids and ensuring the gravel surface is level. If desired, you can add another thin layer of gravel across the top surface to give the driveway a smooth finish.

If the gravel grids are being used in a pedestrian or light-duty application, they can be installed directly onto the soil.

Can I install a gravel driveway myself?

Installing a driveway yourself isn’t recommended unless you have previous related experience. It’s advisable to contact a local tradesperson to carry out the installation. To ensure that you’re hiring a competent professional, look for reviews and testimonials from their previous customers.

If you decide to install the grid driveway by yourself, follow a detailed installation guide to ensure you don’t miss any vital steps in the process.

How do I maintain my gravel driveway?

Installing plastic grids reduces the frequency of maintenance needed, but regular maintenance is still valuable. Regularly remove debris and weeds from your driveway to keep it looking clean.

After your gravel driveway has been in place for a few years, you should look into the cost of a professional driveway clean.

Where do I install the weed-proof membrane?

It’s advisable to install a weed-proof membrane to prevent weeds from sprouting up between your gravel rocks. If you’re using one of these membranes, it should be installed underneath the grids after the sub-base has been laid.

Are gravel driveways cheap compared to other driveways?

Other popular driveway surface materials include block paving, concrete, resin, tarmac, and asphalt. The cost of laying a plastic grid-bound gravel driveway is relatively cheap.

The cost of tarmac driveways is similar, but tarmac provides a less traditional aesthetic than gravel and lacks natural permeability. Asphalt driveways cost around the same amount.

Like gravel, cobblestone driveways are a great excellent option for people wanting a traditional finish to their driveway. However, the price of a cobblestone driveway is higher than that of a gravel driveway.

The Bottom Line

If you want to enjoy all the advantages of a gravel driveway while improving its lifespan and effectiveness for a minimal cost, invest in gravel driveway grids.

Plastic grid driveways are attractive, accessible, and benefit from natural permeability. Contact a local tradesperson today for an accurate quote and further information on how you can install a gravel grid-bound driveway.

Once your plastic grid driveway is installed, you’ll get to reap the rewards of an attractive, solid and stable gravel driveway.
