How to lay decking on soil
If you’re looking to create a stylish outdoor space, installing a deck can be a great option. Decking not only enhances the aesthetic appeal of your backyard but also provides a practical area for relaxation and entertainment. While many people opt for laying decking on a concrete or stone base, it is also possible to lay decking directly on soil. This can be a cost-effective and relatively simple way to create a deck, as long as you prepare the soil properly and follow some important steps.
Planning and Preparing the Area: Before you begin the installation process, it is important to plan and prepare the area where you want to build your deck. Measure and mark out the dimensions of the deck, considering factors such as the size, shape, and intended use of the deck.
Next, clear the area of any vegetation, rocks, and debris. This will make the installation process smoother and prevent any damage to your decking boards. Remove any plants, roots, or grass from the soil using a shovel or spade. Ensure the soil is level and firm, making any necessary adjustments to create a flat surface. Adding a layer of landscaping fabric to the soil can help prevent weed growth and improve drainage.
Preparing the Soil
Before you start laying your decking on soil, it’s crucial to properly prepare the ground. By doing some groundwork, you can ensure that your deck will be stable, long-lasting, and able to withstand the elements. Here are the key steps to follow:
1. Clear the Area
Begin by clearing the area where you plan to lay the decking. Remove any plants, weeds, or grass from the site to create a clean and even surface. It’s important to thoroughly remove all vegetation as it can grow underneath the deck and cause problems in the future. Use a shovel or a spade to dig up and remove any roots or rocks that may be present.
2. Level the Ground
Next, you need to ensure that the ground is level. This will provide a sturdy foundation for your deck and prevent any future issues. Use a level and a long, straight board to check the ground’s surface. If you notice any unevenness, use a shovel or a rake to level it out. By doing this, you’ll create a flat and even surface for your deck to rest on.
Additionally, consider installing a weed barrier or a geotextile fabric to prevent any unwelcome plants or weeds from growing up through the deck. Simply lay the barrier on the leveled ground, overlapping the edges, and secure it in place with landscape pins or staples.
3. Compact the Soil
To further ensure the stability of your deck, it’s vital to compact the soil. Use a compactor or a tamper tool to firmly press down on the soil. This technique will help to eliminate any air pockets and provide a solid base for your decking. Make sure to compact the soil evenly across the entire area where you’ll be laying the deck.
By properly preparing the soil before laying your decking, you’ll create a solid foundation that will help to ensure the longevity and stability of your project. Taking the time to clear the area, level the ground, and compact the soil will greatly contribute to the success and durability of your deck.
Removing Vegetation
To ensure a stable and long-lasting deck, it is important to remove any vegetation from the area where you plan to lay your decking. Vegetation can grow and cause the deck to become uneven or unstable over time. Here are some steps to properly remove vegetation:
Step 1: Clear the area
Start by clearing the entire area of any plants, grass, or weeds. This can be done by using a shovel or a garden rake to remove the top layer of vegetation. Make sure to dispose of the vegetation properly.
Step 2: Prepare the soil
After clearing the area, you’ll want to prepare the soil to prevent any future vegetation growth. This can be done by using a root killer or weed control fabric. Apply the root killer according to the instructions on the packaging or lay the weed control fabric on the soil. Ensure that the entire area is covered.
Note: If you choose to use a root killer, make sure it is safe for use around plants and other living organisms.
Step 3: Level the area
Once the soil is prepared, use a leveling tool such as a rake or a leveling board to ensure that the area is even and smooth. This will help to prevent any unevenness or sloping in the deck.
By following these steps to remove vegetation, you’ll create a solid foundation for your deck and increase its overall longevity.
Leveling the Ground
Before laying your decking on soil, it is crucial to ensure that the ground is level to prevent any future problems. Here are the steps to level the ground:
Step 1: Clear the area
Start by clearing the area where you plan to lay the decking. Remove any weeds, rocks, or debris from the surface.
Step 2: Mark the perimeter
Use a tape measure, stakes, and string to mark the perimeter of the decking area. This will give you a clear idea of the size and shape of the space you will be working with.
Step 3: Excavate the soil
Use a shovel or a spade to excavate the soil within the marked perimeter. Remove the top layer of grass or vegetation along with any other organic matter. You will need to dig down to a depth of about 4-6 inches.
Step 4: Level the ground
After excavating the soil, use a rake or a shovel to level the ground. Break up any large clumps of soil and fill in any low spots. The goal is to create a smooth and even surface for the decking.
Step 5: Compact the ground
Once the ground is leveled, use a tamper or a plate compactor to compact the soil. This will help to stabilize the ground and prevent any future sinking or shifting of the decking.
Step 6: Check the level
After compacting the ground, double-check the levelness using a spirit level or a straightedge. Make any necessary adjustments to ensure that the ground is perfectly level.
With the ground properly leveled, you can now proceed to lay your decking boards. It is also recommended to lay a weed barrier or a landscape fabric before installing the decking to prevent weed growth.
