Plastic parking grids are an eco-friendly and cost-effective solution for households and businesses. They are usually made from recycled plastic, making them environmentally friendly, and are designed to be used on gravel driveways, car parks, and paths to help keep the gravel in place and provide a more stable surface. Laying plastic parking grids is a straightforward process that can be accomplished with basic DIY skills and does not require any special tools. The process involves preparing the area, laying a non-woven geotextile membrane, interlocking the grids, filling them with gravel or other infill materials, compacting the gravel, and smoothing the surface.

What You'll Learn

Prepare the area
Preparing the area is the first step in installing plastic gravel grids. This process involves several stages, starting with taking accurate measurements of the area. Since most driveways are not perfectly square, it is recommended to divide the area into smaller square sections and calculate the length and width of each section to determine the total surface area. It is also important to consider whether you are creating a new surface or replacing an existing one. If there is already a surface in place, such as concrete, tarmac, or block paving, you need to decide if it needs to be removed.
The next step is to excavate the existing surface to a depth that accommodates the grid thickness and any sub-base material. This is followed by installing a sub-base layer, such as crushed stone or gravel, to create a stable foundation. It is crucial to ensure that the sub-base is level and well-compacted to prevent future settling.
After preparing the sub-base, it is time to lay a permeable weed membrane over it. This step is essential to prevent weed growth while maintaining proper drainage. The membrane will help inhibit weed growth while allowing water to drain through, ensuring the longevity of your gravel surface.
Once the membrane is in place, you can begin levelling the ground using a rake and a compactor if needed. This step ensures that the surface is even and ready for the installation of the gravel grids.

Lay a membrane
Before laying the membrane, you should prepare the area by removing any surface soil, debris, weeds, and roots. Then, level the ground using a rake and a compactor if required.
Once the ground is level, lay a non-woven geotextile membrane. This membrane will help stop the gravel from sinking into the dirt beneath and allow for water drainage. The membrane should be laid below the gravel grids and can also be used to cover the sub-base.
When laying the membrane, ensure that it is level and covers the entire area. You may need to cut the membrane to size using a knife or scissors. Make sure there are no gaps or overlaps in the membrane, as this will ensure the stability of the grids above.
After the membrane is in place, you can begin installing the gravel grids.

Interlock the grids
Interlocking plastic parking grids is a straightforward process that can be done quickly and easily. Before interlocking the grids, you should prepare the area by removing any surface soil, weeds, and debris. You can then level the ground using a rake and compactor.
Once the ground is level, you can start laying the grids, starting at one corner and working outwards. The grids should be gently tapped into place with a rubber mallet or a similar tool. As you lay the grids, interlock them securely, following the manufacturer's instructions. For example, some grids simply require you to push down from above, while others may clip together.
If you need to cut the grids to fit the space, mark the line to be cut, secure the grid, and carefully cut along the line with a circular saw or fine-toothed saw. Always follow safety guidelines when cutting.
After all the grids are in place, you can fill the area with gravel, soil, grass seed, or another suitable infill material. Use a rake to distribute the material evenly, ensuring that all gaps are filled. Finally, compact the material with a wacker plate to ensure a stable and even surface.

Fill with gravel
Once the area has been levelled, compacted, and the membrane installed, you can start filling it with gravel. Using a rake, spread the gravel evenly over the grids, ensuring that all gaps and spaces are filled.
After spreading the gravel, you will need to compact it to ensure a stable and even surface. You can use a wacker plate or similar tool to gently compact the gravel.
When installing gravel grids on a brand-new surface, ensure that the sub-base layers are compacted and deep enough. The sub-base should be at least 150mm deep when compacted. Beneath the sub-base is a permeable geotextile/membrane that allows water to trickle through to the soil below.
Gravel grids are usually filled with clean gravel, which has fewer fines, so less dust is likely to become airborne during dry weather. The gravel size should be between 10-30mm, with 20mm angular gravel being the best option. Using stone smaller than 10mm may cause it to get stuck in tyres, while stone larger than 30mm can be difficult to fill.

Smooth the surface
To smooth the surface of your plastic parking grids, follow these steps:
First, prepare the area by removing any surface soil, including debris, weeds, and roots. Then, level the ground using a rake and a compactor if required. This step is crucial to ensuring a smooth and even surface for your plastic parking grids.
Next, lay a non-woven geotextile membrane. This membrane helps prevent the gravel from sinking into the dirt beneath and allows for proper water drainage. Make sure to cover the entire area with the membrane to ensure maximum stability.
Now, you can start placing the plastic parking grids. Begin at one corner of the area and work outwards, interlocking the grids as you go. Use a rubber mallet or a similar tool to gently tap the grids into place, ensuring they are securely interlocked.
Once all the grids are in place, it's time to fill them with gravel. Use a rake to distribute the gravel evenly, making sure to fill all the gaps and spaces within the grids. Spread the gravel across the grids in a smooth and level manner.
After the gravel has been evenly spread, it's important to compact it to create a stable surface. Use a wacker plate or similar tool to gently compact the gravel. This step will help remove any air pockets and create a sturdy base.
Finally, use a broom or rake to smooth out the surface of the gravel and remove any excess. Sweep the gravel gently in a consistent direction to create a uniform finish. This final step ensures a neat and tidy appearance for your plastic parking grids.

A sub-base is a layer of material such as crushed stone or gravel that provides a stable foundation. It should be compacted and levelled before laying the plastic parking grids.
Measure the area you want to cover with gravel grids and calculate the number of grids by multiplying the area in square meters by 4. Then, use a gravel calculator to determine how much gravel you need.
