Are you tired of elevated decking? Do you find it stressful to climb your decking anytime you want to use it? Or, do you want a decking in your garden among the grasses? If you answer yes to all these questions, then it is time for you to consider how to build a flush ground level composite decking.

What Is a Flush Ground Level Decking?

You can guess from the name that a flush ground level decking is one that is close to the ground. This is the kind of decking that you will build in your garden or your backyard. Also, if you want a decking that will connect your backyard to your home, then you should consider a flush ground level decking. This kind of decking is just some feet above the ground, and they are easy to build. 

The reason for that is they don’t require a ladder or railing. Also, depending on where you live, they may not require a permit. And they don’t need steps. This means that a flush ground level decking will save you money. Another benefit of a ground-level garden is that they don’t pose any risk—no need to fear that you will fall off your decking when you are walking on it. Also, you don’t have to fear that your flush decking will collapse under its weight if the supporting posts collapse.

Step One – Plan Your Decking

The first thing to do when building a flush ground level decking is to mark or measure the area you want to build your composite decking. Remember that you are building the decking in your garden, so you will have to remove grasses from the area. You can achieve this easily by using a shovel. After removing grasses, you can cover the area with fabric to prevent grasses from growing there again. 

Make sure that the spot is adequately landscaped so that you will get an even surface. You have to consider drainage in your garden. Is your garden or backyard slopy that water flows in one direction? Make sure that water does not settle on your composite decking by not building it in the waterway. We recommend that you landscape your garden if you have to, to make sure that it is balanced.

Step Two – Build the Substructure

Building a substructure might come as a surprise to you because you are building a flush decking that is not high from the ground. Remember that all building material must have a foundation for it to stay strong in the ground. Some might not recommend it, but we recommend using short treated wooded posts for the foundation of your decking. The posts should be short and sunk deep into the ground. Aside from wooden posts, you can use concrete. 

Just put concrete at strategic points in the area you will install your composite decking. It is on this concrete that you will put your composite decking joists. The same goes for the wooden planks. The part of the planks that is above the ground should be enough to support your joists. The posts and the concrete will serve as the foundation of your composite decking.

Step Three – Build the Joists

Your joists are what you will install your composite decking boards on when you build them. You should start with the outer joists. What this implies is that you should connect your planks to the posts and do it all around until you have finished.

 After joining the outer joists, you can do the same for the inner joists. The planks should intersect if you want a strong substructure. Make sure that the space between them should not be more than 16 inches apart. This is to support the composite decking boards well. 

Step Four – Lay the Composite Decking Boards

Arranging your composite decking boards is the next thing after you have built the joists. The best thing is to start from the edges of your decking. You should use starter clips for the first sets of composite decking.

 Starter clips are better when you use them close to a wall. It is the clips that will hold down the decking to the joists. After installing the first sets of decking, you should use intermediate clips for the other composite decking boards. Please ensure that the space between the composite decking boards is 5 mm apart.

Step Five – Cover the Edges of Your Composite Decking

Because your composite decking is not too high from the ground, covering the edges is not too difficult. To do that, you will need a fascia to cover the edges of your decking.


The best way to build a flush ground level decking in your backyard is by following our recommendation. Make sure you use good composite material to build the decking.
