# How Deep Do You Need to Dig For a Gravel Driveway?

Posted on: July 23, 2022

If you have a gravel driveway, you need to know how much gravel you will need to fill the trench. It is important to dig a deep enough trench, because shallow trenches will have poor drainage. In this article, you will learn how to calculate the amount of gravel needed for your driveway, create a gravel border, dig a drainage trench, compact the driveway, and more.

## How to calculate the amount of gravel needed for a driveway

How to calculate the amount of gravel needed for your driveway depends on the size of the area to be covered. Measure the length, width, and depth of the driveway to determine how much gravel you will need. Then, multiply the dimensions by the depth of the gravel. Then, multiply those numbers by seven to get the total amount of gravel. You can use the same formula for other projects, such as driveways.

To get the exact number of cubic feet of gravel required, multiply the length, width, and depth measurements together. Multiply this total by 27 to get the volume in cubic yards. Then, use that volume to estimate the total amount of gravel needed. Make sure to consider other costs in the process of preparation. A gravel driveway calculator will help you with this. Here are some tips for making the most of your driveway gravel project.

## Creating a border for a gravel driveway

To protect your gravel driveway, you may want to create a border around the perimeter. Driveway edgings can come in many materials, and are not only protective of the gravel, but also beautiful. If you’re going with a natural appearance, you can use boulders as a border. Boulders are a beautiful and natural way to keep loose gravel inside your driveway. For an even more natural look, you can find rock locally. You can also choose Belgian blocks. These large paving stones are typically made of granite and are extremely robust. They provide a timeless design element to your property.

If you’re going with a natural border, you may want to choose a light-colored grass. A vibrant green plant will provide a nice contrast to the dark-colored gravel. You can also opt for a softer border by planting lavender bushes. A light-colored gravel will complement the vibrant greenery in a natural setting. Using an attractive, natural border around the gravel driveway is an ideal way to add privacy and character.

## Digging a drainage trench

Digging a drainage trench for a new gravel driveway requires a bit more work than digging a regular one. The proper drainage requires a steep slope of 2 inches for every 10 feet of driveway length. This slope should be towards the point where the water will eventually drain. Digging a shallow trench will result in poor drainage. Once you’ve gotten the drainage right, you can put down the gravel.

The gravel that you lay on the driveway should be small enough to fit in the trench. It should have a depth of approximately 12 inches. You can use a walk behind trencher to dig this trench for you. Once you’ve dug the trench, add landscape fabric and three inches of coarse gravel. Once you’re satisfied with the slope, place a pipe and drain it from the trench.

## Compacting a gravel driveway

Before you begin laying gravel, you should prepare the area by gathering the proper tools for the project. These tools include a wheelbarrow, shovel, rake, gardening gloves, and a backhoe or tractor. The next step is to clear any topsoil and grass. If you cannot do this by yourself, you may want to hire a bulldozer operator to do it for you. Once the area is level, you can compact it using a mechanical compactor.

The base layer of your gravel driveway should be properly graded and cohesive to prevent weeds from growing through it. It can be composed of gravel, crushed stone, or a combination of these materials. Ideally, it should be made from fully fractured aggregate without excessive fines. This will ensure maximum density, but further compacting the material may cause it to shift. Make sure the base layer is completely level. Once it is level, install the gravel driveway and install any required timber edging.
