In-Ground Trampolines

What a great idea!

There are two approaches one can consider when lowering a trampoline into the ground.

1. With the legs on the trampoline
2. Without the legs, but using leg brackets that are bolted to the retaining wall.

When trampolines are lowered into the ground with the legs attached there will be a retaining wall which is exposed. The custom-made pads that cover this wall can dramatically increase the cost of this application.

The second approach is to bolt the trampoline to the top of the retaining wall by means of leg brackets.  Since the legs are no longer assisting in supporting the trampoline, we recommend that rigid pipe (which we supply) be inserted into the frame for added support.

Trampoline Country offers a copy of an architectural drawing (as a guide) for both these in-ground applications. Please call the office 1-877-251-5867 for more information.

 In-Ground Trampoline Information

In-ground trampolines are a great addition to most backyards.

Important aspect to consider are as follows:

The shape of the trampoline is of utmost importance. While a hole can be dug for any shaped trampoline, the simplest hole to excavate would be for the rectangular trampoline.

Retaining Wall

Retaining walls are required to hold the soil in place. There are a number of options available for this. If a more permanent retaining wall is required poured concrete, or cinder blocks work well. If a less permanent wall is required one could consider pressure treated wood.

Soil type, water table and drainage

Proper drainage under the trampoline is essential. If there is insufficient drainage a drainage system will be required.


Trampolines need to be level and have a solid base. The legs should be placed on concrete pads or a wooden base. If they are placed on a wooden base they need to be clamped firmly in place. A ¼” layer of rubber is required under legs placed on concrete. This prevents damage to the underside of the legs.


We recommend that the trampoline be elevated above the ground level by approx 3” – 5”. This is essential for air movement under the trampoline. If the trampoline is level with the ground surface, the performance may be hampered.  Air that is forced down by the bouncer needs a place to go when it return to the underside of the bed. If the trampoline is flush with the ground  there is not place for the air to go except the underside of the trampoline bed. This will reduce the quality of the bounce.

Industry standards for clearance is 5 feet from the outside of the bed. We suggest a clearance of 5 feet from the outside of the frame.
