How To Build a Raised Concrete Deck

Identify the Type of Concrete Deck You Want

The type of concrete decking you choose will depend on the size and use of the deck, as well as your budget. 

A poured concrete deck may be the best option for building a large outdoor entertaining deck. 

This type of deck requires a professional to install, but it is the most solid and durable option. 

A stamped concrete deck may be a better choice for a smaller patio that won’t use for entertaining often. This option is more affordable and can install by a DIYer. 

A precast concrete deck is the least expensive option if you’re on a tight budget. It is quick to install and is perfect for patios and small decks.

Planning & Designing for The Raised Concrete Deck

Planning and designing for your raised concrete deck is an important step and should not overlook. The first step is to determine the size and shape of the deck. 

Consider all the activities you plan to use the deck for and ensure the space can accommodate them.

Once the size and shape are determined, the design must finalize. 

Measure the space and draw a detailed plan that includes the location of the posts and any other materials you plan to use for the structure.

Consider any obstructions, such as trees and other structures, and ensure the design will fit the space. 

Finally, consult a professional to ensure the design meets local building codes.

Preparing The Area for The Raised Concrete Deck

Before building your raised concrete deck, you’ll need to prepare the area. Start by measuring the area you plan to build on and marking the corners with stakes. 

If you plan to build onto an existing structure, check to ensure it can support the weight of the new deck. Clear vegetation from the area, dig down 8-12 inches, and remove any dirt. 

Level the ground, fill any low spots with gravel, and tamp it down. Once the area is flat and level, you can begin laying the concrete.

Calculate the Size and Location of the Deck

Once you have decided on the size and shape of your deck, you will need to calculate the size and location of the deck. 

It does a critical step, as the location and size of the deck will determine the number of materials you will need to purchase. 

If the deck is in an area that is too small, it may not support the weight of the deck and the people on it. 

If the deck is in an area that is too large, you may save materials. 

To calculate the size and location of the deck, use a measuring tape and calculate the area of the proposed deck. 

Once you have this information, you can determine the deck’s exact size and location.

Gather Necessary Materials and Tools

Before getting started with the construction of your raised concrete deck, gathering all the necessary materials and tools is crucial.

It includes concrete, rebar, lumber, screws, nails, a power drill, shovels, trowels, a level, and a wheelbarrow. Additionally, it is crucial to double-check that you have all the supplies you need to complete the job, such as concrete mix, sealant, and any other materials you may need for the specific project. 

Prepare the Foundation of the Deck

The deck’s foundation is essential for creating a safe and secure structure. The deck must be able to support the weight of the people using it. 

To prepare the foundation, you will need to excavate the area where the deck will build. 

Remove any dirt or debris from the area and level the ground. If necessary, use concrete blocks or gravel to create a level surface slightly higher than the ground surrounding the deck.

Once the foundation is complete, you can build the raised concrete deck.

Build the Frame and Arrange the Beams

One important step in building a raised concrete deck is to make the frame and arrange the beams. Start by attaching the four posts corner ones) to the concrete footing and then secure the interior seats. 

You may need to use shims to adjust the height of the beams to ensure that the frame is level. Once the frame and beams are in place, you can begin pouring the concrete.

Install the Forms and Reinforcements

After the foundation of the raised concrete deck has been laid, it’s time to install the forms and reinforcements. 

First, measure the area you want to pour the concrete and mark it off with stakes and string. 

Then install the documents, typically made of wood, plastic, or metal. These hold the concrete in place once it’s poured. 

Reinforcements, such as metal mesh or rebar, should also be installed. 

The struts provide extra support and strength to the concrete and help prevent cracking. Once the forms and reinforcements are in place, you’re ready to pour the concrete.

Pour the Concrete and Level the Deck

Pouring concrete and leveling the deck are essential in constructing a deck. The concrete provides a foundation for the deck and ensures that the deck is stable and safe. 

Before pouring the concrete, it is vital to ensure the area is clean, level, and free of debris. Once the area is ready, the concrete should be mixed according to the manufacturer’s instructions and poured into the room. 

The concrete should then be spread evenly and leveled with a trowel. After the concrete has dried, the deck can build on the ground surface. 

Following these steps will provide a secure and stable foundation for the deck that will last for years.

Finishing the Deck and Curing the Concrete

Finishing the deck and curing the concrete are essential steps in construction. Properly finishing a deck includes sanding and smoothing the surface and then adding a sealant or a finish to protect it. 

Curing the concrete is a process of allowing the concrete to dry slowly and harden over time. 

We should reduce the amount of water exposed to the concrete over several days, followed by gradual dampening.

By doing this, the concrete will become more durable and resistant to cracking or chipping.

Pay attention to the curing instructions provided by the concrete manufacturer to ensure the best results. 

Taking the time to finish the deck and cure the concrete properly will help ensure the longevity and durability of the installation.

Add Railings, Steps, and Other Accessories

Adding railings, steps, and other accessories to a patio or outdoor setting is a great way to add style, safety, and convenience to the area. 

Railings provide a sturdy hand-hold for those needing it and prevent falls. Steps can offer a safe way to move from one level to the next. 

Other accessories, such as planters, benches, and furniture, can help add a personal touch to the space. Whether you are looking to upgrade an existing area, or create a new outdoor space, consider adding these accessories to make it both aesthetically pleasing and functional.

Not only will they improve the look, but they also offer safety and security.

Sealing The Deck

Sealing a deck is an essential part of deck maintenance. It helps protect the wood from weathering and makes it look brand new. 

It also helps keep the wood from rotting and splintering. Before sealing a deck, it is crucial to ensure it is clean and free of dirt, debris, and mildew. 

If you are planning to paint the deck, it is vital to use a primer before applying the sealer. Allow the sealer to dry completely before adding the paint. This guide may assist you if you want to learn about the painting cost.

Sealing a deck helps ensure its longevity and makes it look inviting and inviting to guests.

Adding Structural Supports

Adding structural supports to a raised concrete deck is integral to any construction project and can be critical to maintaining the structure’s safety. 

It involves building supports such as columns, beams, and foundations to support the structure’s weight. 

Structural supports are also crucial for preventing structural movement due to wind and seismic activity. 

Should carefully calculate the size and strength of the supports to ensure that they can adequately support the structure’s load. 

Finishing Touches & Maintenance Upkeep of the Deck

Regular upkeep is critical when it comes to finishing touches and maintenance of outdoor decks. 

To ensure a safe and durable deck, periodic cleaning with mild detergent and a pressure washer do recommend. Additionally, a sealant should be applied every two to three years to protect the wood from weathering and staining. 

Finally, inspect the deck for loose nails, screws, and boards and for any signs of rotting or splintering.

If any of these issues do identify, it’s essential to address them promptly to prevent further damage. 

Regular outdoor deck maintenance will help ensure a long, healthy lifespan.
