Can You Put a Trampoline on Decking? [SAFETY TIPS]

Wondering if you can put a trampoline on a deck? The good news is that you can put a trampoline on decking. You just need to make a few adjustments first.

For many kids, there’s nothing more fun than bouncing on the trampoline. Ideally, a trampoline should be put on the grass, so the kids won’t be landing on wooden decking if they fall off.

But there is a saying that goes “good, better, and best”. Sometimes, all we have to work with is “good enough”, and that’s the case with putting a trampoline on decking. So while it’s not recommended if you have other options, we understand it might be your only option, so let’s discuss how to make it work best!

Safety of Using a Trampoline on the Deck

The first thing to determine is whether it will be safe to use a trampoline on the deck. These are some of the things you should consider when making this decision. 

Condition of the Deck

The best place to start is by looking at the condition of the deck. It needs to be able to cope with both the weight of the trampoline and the person jumping on it. Plus, there will be other objects, like tables or chairs, adding weight to the deck. Sometimes, this can be enough to break the wooden deck. At other times, it will cause the deck’s foundations to shift. Both will leave you with an expensive repair bill.

There are some ways that you can determine whether it will be safe to use the trampoline on the deck. You should start by inspecting the boards. They shouldn’t show any signs of rotting or mold. Both of these can eat through the wood, making it weaker.

It can also be a good idea to get in contact with the people who constructed the deck. They should have completed an engineering assessment of the project. This would have told them how much weight the structure will be able to withstand. You can then calculate the amount of weight that will be on the deck once you add the trampoline. As you are doing this, it’s best to add a little additional weight, to err on the side of caution.

Sometimes, the additional weight of the trampoline will mean that you need to reduce the number of people who can go on the deck at the same time.

Lastly, a trampoline will need flat ground. If it’s uneven, there is a chance that the bouncing might force it to tumble over, injuring the jumper. Usually, this isn’t something that you have to worry about when putting the trampoline on a deck. But it’s a good idea to double-check with a spirit level.

Overhead Space

It sounds obvious, but you need to consider the overhead space associated with the trampoline. We don’t want to risk people hitting their heads against the ceiling as they are jumping. There are a few other potential hazards that you should be wary of. For example, keep them away from trees.

 Most trampolines will come with a mesh enclosure that will be three meters (nine feet) high, though it is possible to bounce higher than this. In most cases, it’s recommended that you have at least six meters (20 feet) of overhead space. But there is no upper limit. Because of this, you don’t want any overhead obstacles.

Amount of Space Around the Trampoline

It’s also important to consider the amount of space that will be around the trampoline. Usually, you will need to have at least 1.5 meters (5 feet) of space around the trampoline. You don’t want to put the trampoline too close to the edge of the deck, particularly if it’s raised. There is a chance that your child can bounce out of the trampoline, over the railing, and end up landing on the ground. As you can imagine, there is a chance that this can lead to some serious trampoline injuries.

It’s also a good idea to consider the size of the trampoline. You don’t want to get something so big that it overwhelms the deck, leaving the rest of the space unusable.

Type of Trampoline

Finally, you should think about the type of trampoline you want to use. On a deck, it’s best to get something that is enclosed. This ensures that your children won’t be able to bounce off and hit the wooden deck. If you are choosing a trampoline, pick something that has a strong mesh. In some cheaper trampolines, the enclosure can break if a child bounces into it.

If you don’t have an enclosure around the trampoline, you can try laying foam mats on the deck when people are using it. While this can be cumbersome and irritating, it will protect people from bouncing off and landing on the concrete floor. These hard surfaces can cause severe injuries.

Using a Trampoline on the Deck

If your deck is suitable for using a trampoline, it’s time to start thinking of how you can set up the trampoline to preserve the decking. Here are some of the ways you can do this.

Protecting the Decking

You don’t want the metal supports of the trampoline to be sitting on the decking. When bouncing on the trampoline, they will move slightly. This can scratch the wooden decking. Plus, the movement of the trampoline can create an annoying knocking sound.

Thankfully, this is an easy problem to solve. All you need to do is place some foam pads underneath the trampoline pads. This will allow them to absorb the movement of the trampoline and dampen the sound. You just need to make sure that you use the same height of foam on both sides, so the trampoline remains even.

You’ll still need to take action if you have a concrete patio. The hard surface will wear down the metal supports on the trampoline. Because of this, you will need to replace the trampoline more frequently. Again, using foam supports should allow you to prevent damage.

Secure the Trampoline

One of the most important things to consider is how the trampoline will be secured. We don’t want it to fall over while people are using it. There are a few ways you can do this, depending on how long you intend to have the trampoline on the deck.

If you only intend to have the trampoline on the deck, you can use sandbags. Put them beneath the trampoline struts. The weight should hold them in place. You can try moving the trampoline, but it should be relatively stable. The sandbags should be heavy enough to stop the trampoline from blowing away in a strong wind.

If you plan on having the trampoline for a longer period, you can drill some small holes through the deck. Then, you can add tie-downs, anchoring them in the ground below. This will be a more permanent solution than sandbags. Though you should consult with your builder before you do this. You don’t want to impact the stability of the deck, increasing the risk that it will collapse. 

To take things to the next level, you can ask your builder about creating a built-in space for a sunken trampoline. While this might be a little more expensive, it does have its benefits. You’ll be able to get the metal legs out of the way, opening up more space on the deck. Plus, it won’t make the deck look as cluttered.

Though it’s best to put a trampoline on the grass, you might be able to use it on a deck. There are a few checks you’ll need to do first. Make sure the deck can handle the weight and there is enough space for people to bounce safely. If it meets these requirements, it should be a simple matter of assembling the trampoline and securing it in place. From there, it’s happy bouncing.
