Step to Follow on How to Build a Raised Deck Over Concrete

Step One: Get a Permit

If you want to include a deck in your home, you should get a permit from the local authorities before starting any construction. A deck is a huge structure and can cause problems when they are not constructed properly. For this reason, many cities require the owner of the house to get a permit before anyone starts building on their property.

It is usual for a homeowner to wait around 30 days before getting a permit. This is because the local authorities have to do a thorough inspection of the property to determine whether it is safe or sound enough to support a deck.

Step Two: Choose Your Decking Material

There are many different types of materials that you can use for your deck. The most common material is wood, such as cedar or redwood, but other options include metal and plastic. There are also composite materials that combine the strength of wood with the low maintenance aspect of plastic or metal.

Composite Wood Is Better Option for Decking

Once you have chosen your material, you then have to choose a design for your deck. Again, there are many different designs available, so pick one that will suit the style of your home and be unique enough to stand out from similar houses in the area.

Step Three: Build Your Frame

Once you have chosen material and a design, it is time to build your deck frame. For most decks, you will want to use four posts spaced evenly apart at each corner of the deck. The posts should be about 2 feet in diameter, and they should sink around 3 feet into the ground so that they are strong enough to support the floor.

Building Frame Over Concrete

With this method, it is also recommended to include diagonal beams to attach the four posts. This will ensure that your deck is properly supported, and it will also make it more durable because it will be less likely that the frame will shift or move over time.

Step Four: Lay Your Joists

After your frame is complete, it is now time to lay the joists. The joists are what connect the floor of your deck to the posts and beams. This keeps everything supported as well as allows you to walk around on the deck. The joists should be laid between 16 and 20 inches apart, depending upon your personal preference.

This measurement should also determine how many joists you need to put in place for your deck frame. For instance, if you use 16-inch joists and the boards are 2 feet long, then you will need to put five joists in place for each board.

Step Five: Lay Your Flooring Material

The floor of your deck is most important, as this is where you will be able to walk and layout. It needs to be made from a material that can withstand rain and sunlight for extended periods. The best materials are synthetic deck boards like wood plastic composite.

This material is excellent because it will be able to stand up against the weather for years without discoloring or warping. It can also be cut with a saw, so you do not have any complex tools to build your deck. This will help in how to build a raised deck over concrete.

Step Six: Build Your Railings

The last step to building your deck is to build your railings. The railing defines the edge of the deck and provides a place for you and others to hold on when walking around the outside of the structure. Most decks have at least one section with a railing all around it, if not most of the deck.

Deck Railing Is a Safety Measures

If you want to sit on your deck, then most building codes will require you to put at least one railing along the edge where a person will be sitting. This is because it gives people a safe place to sit and relax while also keeping them from accidentally falling off the side of the structure.

Step Seven: Maintain Your Deck

Once you have finished building your deck, there are still a few precautions that you should take. Usually, the first thing you will want is to clean your deck so it looks its best. You can wash off dirt and debris using a garden hose with a high-pressure nozzle or even a power washer if you have one available. 

Additionally, you will need to make sure that your deck is maintained regularly. This is because decks are exposed to the elements every day, and they can start to degrade if not cared for properly. Keep your deck; it is best to sweep or power wash away dirt and debris regularly.

Step Eight: Enjoy Your New Deck!

Once you have finished building your new deck, you can enjoy the fruits of your labor. You will now be able to spend time with friends and family enjoying drinks or meals on a whole new level. You can even choose to host parties in this special outdoor space, which can be a great way to entertain guests.

In addition to being an excellent place to have gatherings, you can also use your deck as a sunroom or an additional living area. This way, you can enjoy the benefits of having a deck without having to go outside every time you want to sit down and relax with a cool drink.

Is It Cheaper to Pour Concrete or Build a Deck?

Pouring concrete is far more expensive than building a wooden deck, but it’s also necessary for some circumstances. For example, concrete may be the best option if you have high traffic coming into your yard or perhaps even just children who are likely to run through the area.

It’s also worth considering pouring concrete where you might want to install some water features such as a pond or fountain. With a wooden deck, those features would be difficult to install and then maintain. Other than those considerations, getting a wooden deck installed is likely to cost you far less money than having concrete poured.


The process of building a deck over concrete is straightforward. Even with the few steps involved, it can be done by anyone who has some basic carpentry skills and time on their hands.
