In Ground Trampolines: How to Install A Sunken Trampoline?

A trampoline is a great feature for every yard. If you have kids, you can’t do anything more joyful for them. Even grownups love trampolines.

To install it you have two options. You can either install one above the ground or make it a sunken.

The sunken or ground trampoline has the same level as the ground. It offers more safety for the persons using it. Even if someone falls off, the height from which they’ll fall will be much lower than the other option.

If you choose the ground trampoline, we’re here to show you what you need to do for having it perfect. Follow up if you want to learn how to install a sunken trampoline perfectly.

1. Find the perfect place for it

Before you do anything, you need to find the perfect spot for installing it. The in ground trampoline requires the ground to be leveled perfectly. Additionally, it’s crucial not to have any obstacles around it.

Think about issues that might hurt the users. For example, trees, bushes, rocks, or anything that nature might have placed around it. The best option is a grass yard with nothing surrounding the location. Put aside any toys, objects, or anything that might be a problem if a person lands outside the trampoline.

2. Dig the perfect size

Depending on the size of the trampoline, you need to dig an adequate hole. Measure how much you’re going to need for placing it ideally. See in the instructions about how wide it should be, but pay attention to the depth.

If it can hold people of over 100kg, then be sure that these people will make the pressure higher and the surface to go much lower than what kids would make it go. In other words, make sure the depth is deep enough so people won’t touch the bottom. If they do, some serious injuries might occur.

3. Make sure you add reinforcement in the pit

Digging the hole is not enough. You must reinforce it and make sure that the walls won’t be destroyed under the vibrations or rains that will soften the ground. You should place metal holders and wooden plates to hold it.

There are other options available too, so this is a matter of personal preference. In any case, you must do it properly so the pit isn’t going to be destroyed after a while. Learn more about building a reinforcement here.

4. Install drainage

A pit is perfect for water to get in and stay there. You don’t want to jump in and get soaked. You need the water to be drained from there. That’s why a drainage system must be installed.

Aside from the draining, the trampoline also needs proper air ventilation. Placing flexible pipes that will let the air go in and outside of the pit is crucial for the whole system to work properly. If there’s no air ventilation, it may be destroyed right away.

5. Level the trampoline after placing

At this point, you’re ready to place the trampoline over the pit. Make sure it is perfectly attached to the ground. One of the most important things you need to mind here is the leveling. If there’s one place that is higher than another, then very soon the system will break, and the surface will be torn off.

For this, you need to get a leveling measurement tool and see if something is causing a problem. Check if there are issues to cause this problem. If there is, fix it. You can do this by installing additional materials like wood or rock, which will make the level even on all sides.


Installing an in ground trampoline is not an easy job. It takes a lot of work and perfect planning. However, the results are amazing. It is a lot safer than the other type, and kids simply love it. See more about this here:
