decking over concrete is a quick and easy way to add an additional floor or finished space to your property. To build a deck over an existing concrete foundation, you don’t need any special tools or materials, though you will want to gather instructions and learn how to calculate your building materials.
If you love a nice outdoor space that is close to the house where you feel like you’re in your own little world and not in the middle of the city, then a deck is for you. Decks can be made in many different sizes and shapes, with different materials and prices.
How to build a deck over a concrete patio
A low deck is a great way to build a deck over a concrete patio because it’s inexpensive and easy. The trick is to build the frame for the deck so that it overhangs the concrete by about 1/2 inch. That way, when you pour the cement board, you can use it as a guide to make sure the top of the board is level with the top of your frame.
The first step in building a low deck over a concrete patio is to decide how large you want it to be. You’ll want enough room for at least two people to sit comfortably (and four if possible). If there aren’t any trees or shrubs nearby, you may want to consider adding some shade cloth or an umbrella for shade during warm weather.
Once you’ve decided on size, measure and mark off where your support posts should go. The best place for them is usually midway between each corner and centered on both sides of the patio. These will support all of the weight of your deck and help keep it from sagging over time.
If your yard slopes away from your house or another building, you’ll need to install footings under all corners of your deck so they won’t sink into soft ground over time
Deck framing can be attached directly to concrete, but you should use posts made of pressure-treated lumber.
Deck framing can be attached directly to concrete, but you should use posts made of pressure-treated lumber. The support posts should be at least 6 feet tall, with the top of the post below the frost line. The decking boards will rest on top of the posts, so make sure they are spaced no more than every 16 inches apart. Use screws to fasten the joists to the support posts and to connect them together.
If your patio has been poured with concrete blocks rather than poured concrete, you can build a deck frame directly over the patio blocks. This is especially true if your existing patio is very low and does not have any kind of wall surrounding it (such as an 8-foot-tall cinder block wall). If you’re going to build a low deck over an existing concrete patio, follow these steps:
Make sure that there’s enough depth between each block on your patio so that you can attach deck joists without hitting any blocks when they’re installed in their final position.
Install support posts at each corner of your deck area and attach them securely into
Building a deck over a concrete patio is not that difficult. There are several options for building the deck. The first option is to attach the deck directly onto the concrete. The second option is to build a frame and attach the decking to it. The third option is to build the frame, then let it dry out, and then pour more concrete on top of it. This will make sure that there is no movement in your new decking.
A low deck can be built by attaching 2×6 or 2×8 pressure-treated joists directly onto the concrete patio surface. You can use joist hangers to attach them into place or you can use metal fasteners. To attach them properly you will need to predrill holes through the joists and into the concrete surface.
Adding a deck to your home is an excellent way to increase the value of your property. It also creates a great space for entertaining and enjoying the outdoors.
If you are thinking about adding a deck to your home, you might be wondering how to build a deck over concrete. A concrete patio is an excellent spot for building a deck because it gives you something solid on which to build. The edge of the deck can be attached directly to the concrete patio. This will create a very sturdy base for your deck and make it very strong.
Before you begin building your deck, you will need to make sure that there is enough room around the area where you want to put it. If there isn’t enough room, then you will need to move some bushes or other plants so that there is enough room for both the new addition and any plants that remain in their current locations. Once this is done, then you can start building your new deck!
A deck over a concrete patio is a great way to expand your living space and enjoy the outdoors year-round. The first thing you’ll want to do is install an exterior grade plywood subflooring on top of the slab. You can use pressure-treated plywood or exterior grade, but you don’t need a moisture barrier since concrete doesn’t absorb water.
The next step is to build a frame for the deck using 2×6 pressure-treated lumber. Then install joists on top of the frame, fastening them securely with 3″ deck screws every 6″. Add 2×4 ledger boards at each end for attaching your railing posts (if desired).
Once your framing is completed, attach 1×6 tongue-and-groove deck boards along the bottom edge of each joist with 1 5/8″ galvanized nails driven every 6″. Make sure that these boards are installed flat so that they don’t warp or split due to unevenness in the concrete slab below.
How to Build a Deck on Uneven Concrete
Building a deck over concrete is not difficult, especially if the concrete is relatively flat. If your existing concrete is uneven, you can use it to create a unique look. The steps below will help you build a deck over uneven concrete.
Step 1: Locate the Level Areas
Measure the length and width of the area in which you will be building your deck. Identify any low spots or sags in the concrete that may cause problems when building your deck.
Step 2: Cut Your Decking Boards
Measure and cut each board to fit over the low spots on your concrete surface. You may need to trim some boards down at the ends so that they fit into corners or around posts. Use a circular saw for these cuts if possible; otherwise, use a handsaw or even an axe if necessary!
Step 3: Mark Your Outline With Chalk
Draw an outline of where your deck will go using chalk or spray paint. This outline should include any posts that you want to place along the edges of your decking surface (for support). Make sure that this outline includes any low spots in your concrete so that your decking boards will sit flush with
How to Build a Deck Over Concrete. Building a deck over concrete is an excellent way to create a multi-level deck for a small yard. The only drawback is that it can be difficult to build a level surface on top of uneven ground.
Building a deck on concrete requires some extra attention and patience, but the end result is worth it. Not only does it create extra room for entertaining, but it also adds value to your home when you decide to sell it.
Deck Over Concrete Step-by-Step
1) Start with a level base before you put any pressure on your new deck. You want the area where you will be building your new deck to be as flat as possible so that the structure is stable and doesn’t shift or sink over time. This also makes it easier for you when adding stairs or railings later down the line.
2) Once your base has been leveled out, use stakes and strings to mark off where each joist will go so they all line up properly with each other and meet at the same height across all four corners of your future patio; this will ensure that everything stays aligned when you start nailing down boards in place later on in this process!
3) Now take out
This is a question that comes up a lot, so here’s your answer.
There are two ways to build a deck over uneven concrete. You can either use pressure-treated wood or composite decking that’s designed for use over concrete slabs. The pressure-treated wood will last for 20 years or more, but the composite decking is much lighter and easier to install. It also looks better than pressure-treated wood because it doesn’t need to be stained or sealed as often.
If you’re not sure which option to choose, we recommend composite decking because it’s so easy to work with. But if you have questions about this topic, check out our article on how to build a deck over uneven concrete.
If you want to build a deck over concrete, there are some things that you need to consider. First, you need to ask yourself if the concrete is strong enough to support your deck. If it is cracked or has been damaged in any way, then it probably won’t be able to support the weight of a deck. Also, if the concrete is uneven or has dips in it, then it will be difficult for the joists to rest on it properly. In this case, it would be better to remove the concrete and install plywood instead.
In order for your new deck to be sturdy, you need to make sure that all of the joists are level with each other and even with the ground beneath them. You can do this by using a laser leveler or by shimming one side up until it’s level with its neighbors (you’ll have to do this on all four sides). Once they’re all level, screw them down into place using lag screws so they don’t shift around while you’re building your decking boards over them.
After this step is complete, measure out how much material you’ll need for each board so that they cover all of your joists evenly without overlapping too much or leaving gaps between them where water could settle in between
I want to build a deck on my existing concrete slab. The slab is about 3 feet high and I want the deck to be about 4 1/2 feet high.
I have looked at plans for decks that are built on slabs like mine and they have all been very low decks (about 6 inches off the ground). I am not sure how to make it higher than that.
I looked at the plans for a 12×10 deck and there were no instructions for making it higher.
