Concrete patios are the cheapest and one of the most popular outdoor flooring options available. However, there are several disadvantages of having a concrete patio. For instance, it is susceptible to cracks and staining. They also don’t add as much property value compared to other outdoor flooring choices. For this reason, you may want to replace it with a better option, such as a wood deck. But how can you turn your outdoor concrete patio with a wood deck? 

Replacing a concrete patio with a wood decking is generally straightforward. In most cases, you can build a deck over an existing concrete patio. However, there are cases that you may need to do a few extra steps to ensure the structural integrity of your new deck. 

When Can You Build Over An Existing Concrete?

If the concrete patio is severely damaged, building a deck over it is not recommended. Cracked concrete sinks in the ground over time. Installing a deck over shifting ground can both be harmful to the deck and the people using it. Cracked patios can also have water pooling and freezing problems, which are very detrimental to decking. Water causes moulds, mildew, and rotting in wood.

So if you have a worn-down concrete patio, what are your options? First, you can wait for the concrete to sink completely before building a deck. However, you will still need to fix the cracks to avoid freezing and water problems. Another option is an elevated decking above the concrete using deck posts and a ledger board. For this, you will need to drill holes in the concrete patio for the deck posts, and the deck needs to be attached to the house. 

Lastly, you can take out the concrete patio and work from there. In most cases, if not all, you don’t have to worry about damaging the foundation by removing the old concrete patio.

Step 1: Preparation – Before you start building a deck over the patio, you’ll need to make sure you have the right tools and enough materials to finish it. You’ll need usual construction tools, such as saws, hammers, screws, and levels. You’ll also have to accost for all the deck materials, including the boards and the framing. Besides wood, you can also choose alternatives such as PVC and composite decking. You’ll also want to fix any issue in your concrete, such as water pooling and cracks.
