If your home has a concrete slab patio or stoop, you may be wondering if it’s possible to build a deck over it. The answer is yes – but there are some important things you need to know before you get started.
In this post, we’ll outline the steps you need to take and provide some tips for making the process go as smoothly as possible. So read on to learn more!
Things You Should Consider Before Getting To Work
There are a few things you need to take into consideration before building a deck over concrete. First, you need to make sure the concrete is sturdy and in good condition. If it is not, the deck could potentially sink or wobble.
Additionally, you will need to make sure there is proper drainage around the concrete porch so that water does not accumulate and cause damage to the deck.
Finally, you will need to use a specific type of lumber known as “decking boards” for your deck, as regular lumber will not be strong enough to support the weight of people and furniture.
How To Make Sure The Concrete Is Sturdy And In Good Condition?
To determine if the concrete is sturdy enough for a new deck, you can use a hammer and punch it down with three solid blows.
Doing so will produce a hollow sound if there are any weak spots that need reinforcement.
How To Make Sure There Is Proper Drainage ?
Around The Concrete
If you decide to build a deck over concrete, you should also plan for proper drainage. Water will accumulate on the surface of your new deck if it does not drain properly which can be very damaging to the wood and cause rot over time.
The best way to plan for proper drainage is to dig a shallow trench around the edge of your deck and place gravel in it. This will allow water to run off quickly and avoid damaging your deck.
What Type Of Lumber To Choose For Your Deck?
Decks are typically made out of one of three types of wood: Cedar, Pressure Treated or Redwood.
You may also come across the term “Southern Yellow Pine” which, despite being a species of pine, is frequently used for building decks because it can last a long time outdoors without being treated.
Preparing The Concrete
If you are planning to build a deck over concrete, you will first need to prepare the surface. This involves patching any cracks or holes in the concrete and then applying a coat of sealant.
Once the sealant has dried, you will need to sand it down so that the surface is smooth and even.
Building The Frame Of The Deck
The frame of the deck is typically constructed out of pressure treated lumber, as it is strong enough to support the weight of people and furniture.
The frame is built in a square or rectangle shape, and the boards are then attached to it. It is important to make sure the frame is level before attaching the deck boards, as this will ensure that the deck is stable and does not wobble.
Attaching The Deck To Concrete
Once the frame of the deck is constructed, you will need to attach it to the concrete. This can be done by using either concrete screws or nails, and it is important to make sure that the deck is attached securely to the concrete.
If you are using screws, it is recommended that you use a drill bit that is the same size as the screw. This will help prevent the screws from stripping out of the concrete slab.
Installing The Deck Boards
After you’ve prepared the surface, you can start installing the deck boards. The easiest way to install a deck board to start at one end of the deck and work your way towards the other. Make sure to measure and cut each board before installing it, as mistakes can be costly and difficult to fix.
When installing the deck boards, make sure that they are flush with each other and that there are no gaps. This will allow them to support the weight of your furniture and people easily.
How Do I Choose The Best Decking Materials?
There are many factors to consider when choosing the best decking materials for your needs. For instance, if you are looking for a low-maintenance material, composite or PVC may be right for you.
On the other hand, if you are looking to save some money on installation costs, pressure treated lumber is usually the best option.
Railing posts are usually made from pressure treated lumber as well, and they form the outline of your deck. You will need to install railing posts around the perimeter of your deck with a gap in between them equal to one-half inch per foot width of your deck boards.
Finishing touches: apply a coat of paint or stain for extra durability.
6. Tips for maintaining your deck over time
Keep It Clean
One of the most important things is to clean it regularly. This can be done with a garden hose and a soft brush, or you can use a deck cleaner.
Make sure to read the instructions carefully before using any type of cleaner on your wood or composite deck, as some of them can be harmful to the surface.
