Concrete is one of the most commonly used floorings for outdoor areas. They are stable, durable, and quite easy to set up. Concrete is also long-lasting, as long as done correctly. And it’s also quite easy to maintain. Unfortunately, it’s not very appealing. The good news is, fixing composite decking on concrete is possible. The truth is, it can even make it easier for you to do so. And you don’t need to worry about the functionality, durability, and low-maintenance qualities of your concrete that you’ll be giving up.
Some decks offer the same advantages while giving you a beautiful yard. One such example is composite decking. They are easy to install, don’t require as much maintenance as wood, and can last for a long time. You may have wondered how to install composite decking on concrete. The good news is, it is very easy. Here are some helpful steps and tips on how to do it.
Check the Concrete
The first thing you want to do is to check the concrete. Ideally, you want the slab to be in good condition. Otherwise, it can affect the overall life and performance of the deck.
How can you tell if the concrete is in good condition? First, look at the surface of the concrete slab. Does it have cracks? If so, how big are they? If they are too big, the concrete is likely unusable. How about the drainage problems? Do water regularly pool on your concrete slab? Another thing to look at is whether it’s flat.
While most of these problems have workarounds, it’s best to be realistic when building a deck over concrete. If it’s unusable, it’s better to make some repairs early on rather than doing it after the patio is already on the concrete.
Design and Plan the Deck
Next, you will need to design and plan the deck. For concrete slabs around dirt, you will most likely use most, if not all, the area. If not, you should start marking the boundaries and drawing the layout for the frame.
It’s also crucial that you take consideration of all the issues regarding the concrete slab. For instance, if the deck is flat, make sure to take note of which areas are lower than others.
Build The Frame
After the planning stage, it’s now time to build a deck. There are many ways to go about it, depending on what type of deck you’ll be building. But in general, you will want a floating deck. A floating deck is a deck that is not attached to the walls of the house. The reason behind this is that you can prevent damage from your house whenever something goes wrong about the deck or the concrete slab.
For the frame, you can do the typical joists set up. Do this by installing the rim joists first, followed by regular joists. If you are not going to install beams, you can install blocks in between the joists. They will make the frame more stable. Another way is by using a sleeper system. Like joists set up, you will need to set up sleepers and sleeper joists on the surface of the concrete.
If your concrete is not levelled, you may want to use bricks to elevate some parts of the frame. You can also use brackets and other similar tools to achieve the same effect. Take note, you can not install decking boards directly on concrete. Doing so can damage both the concrete and the decking boards.
Installing The Decking Boards
After setting up the frame, all that’s left to be done is to install the composite decking boards. You can attach them to the deck frame the same way. Depending on what type of boards you’ll be using, you may use screws, nails, or clips.
Attach them using the appropriate fastening system. Make sure to follow the instructions from the boards’ manufacturers, if available. Also, make sure that you observe proper deck spacing, as this helps with drainage and airflow.
Aside from composite decking boards, you can also use composite decking tiles. Fixing composite decking on concrete is easy. They offer the same features as the boards. The difference is that they are easier to install. Most tiles lock in place using simple clips and systems. Regardless of what you use, one thing is for sure; you can say goodbye to your old, boring concrete slab, welcome a new and beautiful composite decking.
