How to Make a Concrete Deck

Transform your outdoor space into a functional and stylish oasis with a concrete deck.

Here's a step-by-step guide to help you create a concrete deck that's both beautiful and long-lasting.

Planning Your Concrete Deck

Before you start, it's crucial to plan your deck carefully. Consider the size, shape, and location of your deck, as well as any local building codes and regulations. Sketch out your design, including the dimensions and any features like stairs, railings, or built-in seating.

  • Concrete mix (ensure it's suitable for outdoor use and contains fibers for added strength)
  • Concrete forms (pressure-treated lumber works best)
  • Reinforcing bars (rebar)
  • Welded wire mesh
  • Concrete sealant
  • Tools: shovel, wheelbarrow, trowel, level, tape measure, saw, and safety gear (gloves, goggles, etc.)

Preparing the Site

Start by clearing the area where your deck will be built. Remove any vegetation, rocks, or debris. Next, stake out the perimeter of your deck using stakes and strings to ensure accurate dimensions.

Excavate the area to a depth of about 8 inches, ensuring the ground is level. Compact the soil using a plate compactor to create a stable base. If your area has poor drainage, consider adding a layer of gravel before compacting.

Building the Concrete Forms

Cut the pressure-treated lumber to create the forms for your deck. Assemble the forms, ensuring they're level and square. Use stakes to secure the forms in place. The forms should be about 4 inches high to accommodate the concrete and rebar.

Create any desired features, like stairs or built-in seating, by modifying the form design accordingly.

Adding Reinforcement

Reinforcing your concrete deck with rebar and welded wire mesh will help prevent cracking and increase its overall strength. Cut the rebar to fit within the forms, spacing them about 12 inches apart. Place the rebar on top of the soil, ensuring it's centered within the forms.

Lay the welded wire mesh on top of the rebar, securing it in place with wire ties. The mesh should also be centered within the forms.

Pouring and Finishing the Concrete

Mix the concrete according to the manufacturer's instructions, ensuring it's a consistent texture. Pour the concrete into the forms, using a shovel to distribute it evenly. Use a trowel to smooth the surface and remove any excess concrete.

Allow the concrete to set for a few minutes, then use a trowel or edger to create any desired patterns or textures. Be sure to wear safety gear, as concrete can be harmful to skin and eyes.

Let the concrete cure for at least 72 hours before removing the forms. Once the forms are off, apply a concrete sealant to protect the surface and enhance its appearance.

Maintaining Your Concrete Deck

To keep your concrete deck looking its best, clean it regularly using a mild detergent and a stiff-bristled brush. Rinse thoroughly with clean water and allow it to dry completely. Reapply the concrete sealant every 2-3 years to maintain its protective properties.
