How Gravel Grids Work

The primary uses of gravel grids for driveways, lawn and/or patio, and walkway areas include the following:

Gravel grids are used to stabilize gravel

Gravel tends to move when a lot of pressure is applied to them. You can support your patio, lawn, driveway, or walkway with the use of gravel grids that hold the gravel in place, thereby reducing shifts. They prevent gravel from moving into flower beds and areas they are not meant to be.

Gravel grids can help limit rainwater runoff

Runoffs have become a major concern whenever torrential rainfall occurs. But the porous ground surface created when gravel is used allows the drainage of rainwater in a more natural way, which can help in reducing runoff. Gravel grids aid this process by prolonging the rainwater's time to reach the water table.

The grid also limits the amount of sediments rainwater carries during movement, thus curbing the impact of flooding.

How Do You Install A Gravel Grid?

When installing gravel grids on your driveway, patio or walkway, make sure to follow these best practices:

1. Create a good base underneath

Having a good base will prevent the gravel from sinking into the ground. It would also make it easier to maintain the surface with minimal upkeep. A good base is usually made up of sand, soil, and stone dust mixed with water until it becomes thick enough to stay in place when dry.

2. Always make sure your edges are well bound on every side

When your edges are properly bound, the chances of damage to your grids are low. This is one of the crucial parts of gravel grid installation as it determines how long your gravel grids will last. Mistakes at this point may cause the stones to spill out.

3. Ensure that the appropriate size of infill material is used

The drop height of your infill material should be no more than 3.28 feet. Also, make sure that your infill material is adequately arranged to avoid lifted cells. While filling each cell, it is advisable to fill and spread them equally using a shovel or rake.

There are different types of gravel with dissimilar sizes that you can use to fill your gravel grids, but it's better to choose the right size of gravel, depending on where you are working on. For driveways and walkways, it's best to use pea gravel.

If you desire a natural-looking driveway, you can also consider using crushed granite (decomposed granite). Creek stones can also be used on walkways, patios, and driveways.

Is Installing Gravel Grids Worth It?

Yes, gravel grids are worth installing, especially with their positive sides that outnumber the downsides.


  • Gravel grids are easy to install (in any weather) and require less maintenance. This makes them ideal for people who don't want to spend their time shoveling or scraping ice off their driveway daily. Since gravel grids are permeable and easy to clean, they are a great alternative to other types of hard surface materials like concrete or asphalt.
  • Gravel grids are usually made from natural stones, which makes them durable.
  • They are among the affordable base system designs.
  • Gravel grids can be installed on any type of surface.
  • This type of flooring provides good drainage so you don't have to worry about water pooling on the surface, which may cause damage to your home's foundation or siding.
  • They can benefit people living in a sloppy area as they serve to keep the gravel in place.


  • Gravel grids can be slippery if they get wet or when it rains.
  • They can be difficult to walk on if not properly installed, so it's important to ensure that the base is well leveled before laying down the gravel grid.
  • When going for a more traditional look outside your home, gravel might not be the best option.

Taking Care of Your Gravel Grids

To keep your gravel grid in good shape, you need to remove any weeds that sprout up from time to time and rake it once or twice a year. Gravels can eventually break down if they are not well taken care of, so they should be maintained.

Always be mindful of debris that accumulates on top of the gravel grid and make sure you clean them up. This will prevent the growth of weeds, making it easier for you to maintain the rest of the area around the gravel grid.

Gravel Grid on Slope

As a homeowner, you may want your gravel to stay stable on sloppy areas of your home. This can be achieved when gravel grids are installed. Gravel loss can be prevented when gravel grids are used on any sloping surface. Using decorative gravel for sloppy areas can be problematic, but with good gravel retention grids, a gravel slope can be effectively stabilized. Also, the development of ruts and potholes can be prevented when gravel grids are installed on sloping surfaces.
