How to Dig Through Clay

Digging through clay can be a daunting task, but it doesn’t have to be. With the right techniques and tools, you can easily break through even the toughest clay soil. Whether you are starting a garden or building a foundation, understanding how to dig through clay is essential in many construction and landscaping projects.

In this guide on, we will discuss the different types of clay soil, the challenges of digging through clay, and important tips to help you successfully dig through it.

Types of Clay Soil

Clay soil is made up of tiny particles that are densely packed together. These particles stick together easily when wet, making the soil heavy and difficult to work with. There are several types of clay soil, each with its own unique properties:

Kaolinite

This type of clay soil is typically found in areas with warm, humid climates. It has a low shrink-swell capacity, meaning it does not expand or contract significantly with changes in moisture levels. However, it can become very hard when dry and waterlogged when wet.

Bentonite

Also known as “swelling clay,” bentonite is able to absorb large amounts of water, causing it to expand significantly. This makes it a challenging type of clay soil to dig through as it can become very compact and sticky when wet.

Montmorillonite

Similar to bentonite, montmorillonite has a high shrink-swell capacity and can also hold large amounts of water. This type of clay soil is often found in areas with moderate to high rainfall and can be difficult to dig through due to its swelling properties.

Illite

Illite is a type of clay soil commonly found in mountainous regions or areas with lower levels of precipitation. It has a medium shrink-swell capacity and is easier to dig through compared to other types of clay soil.

Needed Tools and Materials

Before you begin digging through clay, it’s important to have the necessary tools and materials on hand. Here are some essential items that can make the process easier:

Shovel:

A sturdy shovel with a sharp edge is crucial for breaking through the tough layers of clay soil.

Pickaxe:

If the clay is particularly compacted, a pickaxe can help loosen it up before using the shovel.

Mattock:

Similar to a pickaxe, a mattock is a heavy-duty tool that can be used for breaking through hard clay soil.

Wheelbarrow:

A wheelbarrow will come in handy for transporting large amounts of clay soil or other materials as you dig.

Water:

Water can be used to soften the clay and make it easier to break apart. Keep a hose or spray bottle nearby for this purpose.

Protective Gear:

Clay soil can contain sharp rocks, debris, and even toxic materials in some cases. Be sure to wear gloves, safety glasses, and a dust mask to protect yourself while digging through clay.

11 Step-by-step Guidelines on How to Dig Through Clay

Step 1: Prepare the Area

Before you start digging, clear the area of any debris, rocks, or plants. This will make it easier to work with the clay and prevent any potential accidents. You may also want to mark out the area you need to dig with stakes and string. The more precise your outline, the easier it will be to keep a consistent depth as you dig. It’s also a good idea to wet the area with water before you begin digging. But be careful not to make the soil too wet, as this can create a muddy mess.

Step 2: Assess the Type of Clay Soil

Knowing what type of clay soil you are dealing with will help you determine how much effort and time will be needed to dig through it. If you’re unsure about the type of clay in your area, take a sample to a local soil testing center for identification. The results can also provide valuable information on the soil’s pH levels and nutrient content, which can help with future planting or construction plans. The type of clay soil can also affect the types of tools and techniques needed for digging.

Step 3: Create a Trench

Start by using a shovel to dig a trench along one side of the marked area. This will provide you with a starting point and help define the depth you want to reach. Make sure the sides are angled slightly outward, as this will prevent them from collapsing as you dig deeper. Otherwise, you may need to use wooden planks or other materials to reinforce the walls of the trench. It’s also a good idea to have someone assist you in this step, as it can be physically demanding.

Step 4: Wet the Soil

Once the trench is dug, use water to wet the soil. This will help soften the clay and make it easier to break apart. Use just enough water to moisten the soil without creating a muddy mess. You may need to periodically re-wet the soil as you dig, especially if it starts to dry out. The moisture will also help prevent excess dust from being kicked up while digging. But be cautious not to over-wet the soil, as it can become too heavy and difficult to work with.

Step 5: Use a Pickaxe or Mattock

If the clay is particularly compacted, use a pickaxe or mattock to break it up before using the shovel. This will make the digging process much easier and save you time in the long run. Use the tool to break up the surface of the clay and then use the shovel to remove the loosened pieces. It’s important to take breaks and not overexert yourself, as digging through clay can be physically demanding. You may also want to switch between using the pickaxe and shovel to avoid muscle strain.

Step 6: Start Digging

Using a sturdy shovel, start digging from one end of the trench and work your way across. It’s important to keep a consistent depth as you dig, so refer back to your markings if needed. Try to break the clay into smaller, manageable pieces as you go rather than trying to remove large chunks at once. This will make it easier to transport and dispose of the soil. It’s also a good idea to periodically wet the soil as you dig, especially if it starts to dry out.

Step 7: Remove Excess Soil

As you dig, you may need to remove excess soil from the trench to prevent it from filling up too quickly. Use a wheelbarrow or other container to transport the soil to a designated area. If the clay is particularly wet and heavy, you may need to let it dry out a bit before removing it from the trench. You can also use the water to your advantage by softening and breaking apart the clay as you dig. But be careful not to let the water pool in the trench.

Step 8: Take Breaks

Digging through clay soil can be physically demanding, so be sure to take breaks when needed. Stretching and staying hydrated can also help prevent injuries and fatigue. If you’re working with a partner, take turns digging to prevent overexertion. The key is to pace yourself and listen to your body. It’s better to take frequent breaks than risk injuring yourself. You can also use the breaks to assess your progress and adjust your technique if needed.

Step 9: Monitor Progress

As you continue digging, periodically check the depth and make any necessary adjustments. It’s important to keep a consistent depth throughout the entire area to ensure an even surface once the digging is complete. You may also need to re-wet the soil as you go, especially if it starts to dry out or becomes too tough to break apart. The type of clay and its moisture content will determine how frequently this is needed. It’s also helpful to have a partner monitor the depth while you dig.

Step 10: Finish Digging

Once you have reached the desired depth, remove any excess soil and smooth out the bottom of the trench with a rake or shovel. You can also use this opportunity to remove any remaining rocks, roots, or debris from the soil. Once the surface is even and free of obstacles, you’re ready to move on to your next project. Although digging through clay can be challenging, the end result will make it worth the effort. But remember to take care of yourself and the environment while digging.

Step 11: Clean Up and Store Tools

After you have finished digging, be sure to clean up the area and store your tools properly. If you plan on using them again in the future, make sure to clean off any excess clay residue and dry them before storing them. This will help prevent rust and other damage to your tools. It’s also a good idea to wear gloves while cleaning up, as the clay can still be sharp and abrasive even after it has been dug up. With proper maintenance, your tools will be ready for the next time you need to dig through clay soil.

Following these steps on how to dig through clay will make digging through clay soil a much easier and more manageable task. By properly assessing the type of clay, creating a trench, wetting the soil, using the right tools, taking breaks, monitoring progress and finishing with proper clean-up and tool maintenance, you can successfully dig through clay soil without too much difficulty. Remember to always take your time and stay safe while
