Gravel is necessary for many landscape projects and not just beautiful rock gardens. Retaining walls and other features that require drainage make great use of large gravel to allow water to drain away faster than soil would. When you’re doing a DIY landscape project, it’s important to choose the right type of gravel. Here is an explanation of your options and their benefits.
Gravel intended for drainage projects needs to be large. That way it will not become compacted. Instead, it should stop debris like leaves right at the top layer, and have plenty of room between stones for water to drain down.
In general, you want to aim for ½ inch to 1-inch gravel for drainage. Areas that will see especially heavy flow may need larger gravel. Or, projects without drainage pipes may also need larger gravel. For example, a French drain without perforated pipe needs 1 ½ inch gravel.
On the bottom layer of your project or drain you need stone that is ideally sized for your project. The beauty and coarseness of the stone don’t matter, because it should be covered by a top layer of gravel.
One of your best options is our ¾ inch clear drainage stone. This stone is the perfect middle ground between the ½ inch to 1-inch range that is suitable for drainage projects. It is available at all of our locations. Give our team at Grand River Natural Stone a call today.
You should have a separate layer of gravel for the top of the feature. If you wish to cover this with sod, you don’t need to worry about how it looks. However, for projects where the top layer of gravel will be visible, you want to choose a stone that will enhance the beauty of your project. Here are some options:
For drainage projects, you do not want to use any type of pea stone. While this stone is beautiful and great for other applications it is too small to drain properly.
