How To Install An In-Ground Trampoline


In-ground rectangle trampolines are great if you have a scenic view you wish to protect from the obstruction that a safety net can be, or you live in a high wind area and want to further minimize the risk of a trampoline blowing away. 

We are aware of the number of kids who are into running and flipping on and off objects freely in the name of Parkour and free running; they want an in-ground trampoline but installed above the ground so they can run and jump on and off it. For everyone else, we do strongly recommend although the design of the GeeTramp has legs, to install the in-ground trampoline in the ground in a purpose-designed hole with retaining walls and drainage.

A bonus of a rectangle in-ground trampoline over a, round in-ground trampoline is that the rectangle version is a lot easier to build with nice straight sides and no curves! If you decide to use an in-ground trampoline above ground to be aware of the risk of injury and the severity of it does increase off trampolines without nets.

Why Install a Trampoline "In-Ground"?

Some people have a preference to have their trampoline installed at ground level, here are some of their reasons:

 


How Is It Done?

There are quite a lot of blogs and articles about how to build your own in-ground trampoline. Having not built one in ourselves we don't feel qualified to say any more on the topic other than what many of our customers have fed back to us what they have done.

Here are some techniques used:

Pros And Cons Of An Inground Trampoline

Below we have outlined a few positives and negatives that can come from installing/having an inground trampoline......

 

                             Positives

                                    Negatives

Simple construction and assembly 

Drainage can be an issue for the garden 

Can revert trampoline back to

  above-ground style

The cost of inground installation

can be expensive

 The trampoline frame is still free

to flex as designed enabling

longer life of components 

 If you want to remove the

trampoline in future, you will

need to fill the hole 

The trampoline can be removed 

for any maintenance of the pit,

retaining wall or trampoline

 Trampoline legs can sink into the

dirt over time (needs to have

stable base on legs) 

 Retaining wall looks after all the

soil-related forces 

 

Keeps trampoline and retaining

wall separated 

 

Trampoline looks after all the

jumping forces

 

 


Trampoline Frame Installed Inground

Customers have dug a hole and then simply placed the trampoline with its legs into the hole.

For this type of installation, here is the list of materials you will need and how long it will take: 

 

Materials:

30 x Treated Pine Sleepers (200mm x 75mm x 3 meters) 
2 x Treated Pine Posts (100mm x 100mm x 3 meters)
1 x Large Box 100mm Galvanised Flat Head Nails
1 x Tennis Ball
7m x 5m Weed Matting
 

Timeframe:

4 days of hand digging/wheelbarrowing
1  1/2 days of retainer wall construction and grass replacement
 

 

 

   


Frame Mounted On Top Of Retaining Wall

For this style inground you need to dig a hole, provide some form of drainage to the hole, build a retaining wall the size of the trampoline frame and then secure the frame onto the retaining wall.

This makes the height of trampoline more stable (less likely to sink). It is a simple layout, as it has the least amount of trampoline parts required.

Please note: The retaining wall needs to be stronger than the original frame as it will now be taking all the stress from bouncing. There will need to be some sort of airflow system from under the trampoline.

Retaining Wall Built Around Above Ground Trampoline

This method uses a retaining wall built above the ground, to then put the trampoline inside the retaining wall.

Tips and Considerations:

*Please contact your local council to inquire if a permit is required in your area.

The hole and retaining walls need to be prepared with the following in mind:

 

Methods you can use to overcome restricted airflow when installing an in-ground trampoline:

 

Note:

The trampoline frame sizes listed on our website are for naming the generic size of a trampoline and should be treated as a ballpark reference only.

These nominal sizes should not be relied upon when digging the actual hole or for making the retaining wall. For our rectangle range, the long side rail bows out a little by design which needs to be factored in.

Depending on the installation method you choose, you may also need to allow for an airflow gap. When sizing up to make the hole or retaining wall, it is strongly suggested you already have the trampoline with the mat and springs assembled so you can then directly measure off the "actual" assembled product dimensions.
