Tools You Will Need

Before beginning any construction project, it is important to gather the right tools and materials. Building a raised concrete deck requires a few specific items. These include:

6 Steps Guide on How to Build a Raised Concrete Deck

1. Prepare the Area: 

Preparing an area to build a raised concrete deck is a great way to improve your backyard. If you are preparing the ground where your new deck will be, there are some important steps you must do for it to be safe and long-lasting. Make sure the area is level and consistent by leveling the grade of the underlying soil. This can be done by marking off the area or using a laser level as holes should not deviate more than 2 inches from place to place. 

Great Way to Improve Your Backyard

Additionally, prep what kind of base you would like – gravel, crushed stone, cement or fill dirt – then install it over the entire area of your deck with about 1 inch of space between each layer. This will provide a stable surface for your concrete deck and help support the weight of people and furniture on top. With these steps completed, you can now build a secure raised concrete deck that may even last a lifetime!

2. Install Formwork: 

Building a raised concrete deck is an ambitious project, but it is one that you can do yourself with the right tools. The key to success with this type of project lies in setting up the formwork correctly because it will be the structure that supports and shapes your deck. When setting up the formwork, remember to take into account local regulations such as spacing requirements when placing reinforcing bars and soil conditions in your area. 

To ensure that your formwork remains stable over time, use boards that are at least ONE inch thick and secure them firmly with plywood or nails. Once your formwork is set up tightly and square, fill it with concrete mix and let dry before removing the formwork from around the deck. With patience and attention to detail, you can have a stunning new raised concrete deck in just a few days!

3. Lay the Membrane: 

Install a flexible membrane or foil to separate the ground from the concrete mix and prevent moisture damage. 

Building a raised concrete deck is a great way to provide an outdoor living area for relaxing and entertaining. The first step in creating this space is laying the membrane on which the concrete will be poured. This provides an effective barrier between the underlying deck frame and joists and the concrete, preventing water from seeping in and damage down the road. 

Provide an Outdoor Living Area

Once one layer of the membrane has been applied, additional layers may be put down according to local building codes, with each successive layer being securely sealed into place. Finishing touches to the lay of the membrane can include folding corners around posts and up walls, as well as cutting holes for drains or cables. With proper application of the membrane, you’ll have ensured that your raised concrete deck lasts through many outdoor seasons!

4. Add Reinforcement Bars:

When building a raised concrete deck, adding reinforcement bars is an important step in the process. Referred to as re-bar in the construction world, these metal rods add extra strength and stability to the concrete. Re-bar placement is crucial for the long-term durability of your deck; it should be spread out evenly across the space, making sure not to overlap any of the bars. 

Re-bar should even extend beyond the edges of your deck; when properly embedded into it, this will ensure that its structure remains intact and it can handle heavier loads over time. With proper installation, the re-bar will create a strong foundation that can provide years of use while also avoiding costly repairs down the road.

5. Pour and Level Concrete: 

Building a raised concrete deck is an excellent way to add outdoor living space in a minimal amount of time. Before you begin, there are a few things to consider and steps to follow so that the deck will come out even and secure. Prepare the area for the pour by ensuring that the ground is leveled and has enough support for the weight of the concrete. 

Ensuring That the Ground is Leveled

Once this is done, it’s time to mix up the concrete and start pouring. Make sure that you take your time as you spread out the concrete; be sure to keep it level and consistent as you go to achieve the ideal finish. Finally, use tools such as trowels or screeds to provide texture and ensure that it sets evenly before adding any decorative touches! With these easy steps, you can create a long-lasting raised concrete deck in no time!

6. Finish and Cure: 

Use a trowel to create an attractive finish on the surface of your deck and leave it to dry. Depending on climate conditions, this may take anything from 24 hours to several days. Make sure the area is completely dry before allowing people to walk or sit on it.

With the right steps, any DIY homeowner will be able to successfully build a raised concrete deck. To finish and cure a raised concrete deck so that it is safe and long-lasting, it should first be screeded and tamped until level. After this step is completed, the edges of the concrete should be tooled with an edging tool to create an even joint, which will also help prevent cracking in future use. 

Once the concrete has been allowed to dry thoroughly, it should be sealed or coated with an appropriate sealer or stain to protect it from the elements. With proper care and maintenance, your newly built raised concrete deck should provide many years of service.

By following these steps, you can easily build a raised concrete deck that will provide a beautiful and durable addition to your outdoor space. If you are looking for professional help, many contractors specialize in building raised decks and other backyard projects. No matter what route you take, a raised concrete deck could be the answer to creating your dream outdoor area!
