Step 1: Gather your Materials and Tools

Before you start, you’ll need to gather your materials and tools. 


You’ll need:


  • Measuring tape
  • Wooden stakes
  • String
  • Shovel
  • Wheelbarrow
  • Compacting tool (such as a tamper or plate compactor)
  • Concrete mix
  • Water
  • Concrete mixer (optional)
  • Trowel
  • Level

Step 2: Prepare the Site

The first step is to prepare the site for your concrete base. Choose a location that is level and has good drainage. Use the measuring tape to mark out the area where you want to lay your concrete base. Then, hammer the wooden stakes into the ground at each corner of the area, and tie a string around them to create a frame. Make sure the strings are level and square to ensure your base is the right size and shape.

Next, dig out the area to a depth of around 15-20 cm, removing any plants, stones, or debris. Use a spirit level to ensure that the bottom of the excavation is level.


Step 3: Mix and Pour the Concrete

Now it’s time to mix and pour the concrete. You can do this manually using a wheelbarrow or hire a concrete mixer if you prefer. Follow the instructions on the concrete mix bag to get the right consistency, and add water as necessary. You should aim for a consistency that is firm but not too dry.


Pour the concrete into the excavation, starting at one corner and working across the area. Use a trowel to spread the concrete evenly and ensure it fills all the corners and edges. Once the area is covered, use a compacting tool to smooth and level the surface of the concrete. This will help to remove any air pockets and make sure the base is strong and stable.

Step 4: Allow the Concrete to Cure

Now it’s time to let the concrete cure. This can take anywhere from a few days to a few weeks depending on the weather and the thickness of the base. You should keep the surface of the concrete moist during this time to prevent it from cracking. You can do this by spraying it with water or covering it with a plastic sheet.

Step 5: Add Finishing Touches

Once the concrete is fully cured, you can add any finishing touches you want. For example, you could add a layer of gravel or sand on top of the concrete to improve drainage and create a smooth surface for your structure. You could also add a coat of sealant to protect the concrete from moisture and staining.


In conclusion, laying a concrete base is a crucial step in building a strong and stable structure in your backyard. With the right tools and materials, you can create a solid foundation that will last for many years. By following these simple steps, you’ll be on your way to a successful project.
