How to Lay a Patio for Beginners: The Importance of Leveling Concrete

Written on .

If you’re planning to transform your outdoor space, laying a patio is one of the best ways to create a functional and visually appealing area. Whether for hosting summer BBQs, relaxing with a book, or creating a safe play space for kids, a well-laid patio can significantly enhance your garden’s usability and aesthetics.

For beginners, laying a patio might sound intimidating, but with the right approach—and a focus on correctly leveling the concrete—it’s an achievable DIY project. Here’s a step-by-step guide to help you lay a patio and understand why leveling your concrete is critical to success.

Step 1: Plan Your Patio

Before you begin, determine the size, shape, and purpose of your patio. Sketch a rough plan to visualize the layout and decide what type of pavers or slabs you’ll use. Keep in mind the slope for water drainage—typically, a fall of 1:60 away from buildings is ideal.

Step 2: Gather Tools and Materials

You’ll need the following tools and materials for the job:

  • Patio slabs or pavers
  • Sand or sub-base material (such as MOT Type 1)
  • Concrete mix
  • A spirit level
  • A trowel and spade
  • A plate compactor or tamper
  • String and pegs for marking out
  • A rubber mallet

Step 3: Mark and Prepare the Area

  • Use string and pegs to mark the area for your patio.
  • Dig out the area to a depth of around 150-200mm (6-8 inches), allowing space for your sub-base, concrete, and slabs.
  • Clear away debris and level the ground to create a stable foundation.

Step 4: Lay the Sub-Base

Spread a layer of MOT Type 1 or crushed stone (about 100mm deep) across the excavated area. Use a plate compactor to compress the material firmly, ensuring it’s level. This creates a stable and durable base for your patio.

Step 5: Mix and Pour the Concrete

The next step is preparing your concrete mix. For patios, a standard mix ratio of 1 part cement to 5 parts ballast (or sand and gravel) works well. Add water gradually until you achieve a smooth consistency.

Pour the concrete over the compacted sub-base, spreading it evenly using a trowel. Here’s where leveling becomes critical:

Why Leveling Concrete is Crucial

A perfectly level concrete base ensures:

  • Even Surface: Prevents wobbling pavers or slabs, providing a stable surface for walking and furniture.
  • Proper Drainage: Avoids water pooling, which can damage your patio over time.
  • Long-Term Durability: Minimizes the risk of cracks or uneven settling, which can lead to costly repairs.

To achieve proper leveling, use a straight-edge or screed board to smooth the concrete. Check the level frequently using a spirit level to maintain consistency and the correct slope for drainage.

Step 6: Lay the Patio Slabs

Once the concrete base is level and slightly firm, start laying your patio slabs. Begin in one corner, using a rubber mallet to tap each slab into place. Maintain even spacing between slabs, using spacers if necessary.

Step 7: Fill the Joints

After laying all the slabs, fill the gaps with jointing sand or a mortar mix. Sweep the sand into the joints and compact it to ensure a secure finish.

Step 8: Finishing Touches

Once everything is in place, clean the surface of the slabs and let the patio set for at least 24-48 hours before using it.
