Nearly everyone has experienced using a trampoline at one time or another. Bouncing and somersaulting on the coil sprang stretched material is the fun part, but falling off and injuring yourself is the not-so-fun part. A ground-level trampoline, otherwise known as a pit tramp, is a less visible installation than the more common upright version, and because it's flush with the ground is also safer too. To install such a device in your garden is a straightforward process, but a little planning and excavation is needed.

Things you need
- Spirit level
- Digging implement
- Interlocking retaining wall
Start by marking out the area and digging a hole three feet deep and one foot greater in diameter than the width of your chosen trampoline (a circular trampoline is recommended because the new models usually come with an interlocking retaining wall). Ideally, you need to locate the hole where the ground is flattest.
Make sure your newly dug pit is drained of any water and free of rocks. You may need to provide an additional method of drainage to prevent the hole sinking or shifting.
Attach the interlocking panels (retaining wall) to each other around the sides of the frame. Raise the panels up until they're flush with the trampoline ring, then secure them with screws/fasteners.
Lower the trampoline into the hole, making sure it stands level and is flush with the surrounding ground.
Use dirt and gravel (this substance will help create a sump effect and help prevent standing water) to backfill halfway up the panels on the inside and pack down. This will leave you with a bowl-shaped hole in the interior of the structure. With the remaining dirt, fill in around the outside of the trampoline until it is flush against the frame.
Add the springs, stretch out the mat and add a safety pad.
Tips and warnings
- Understand that the consistency of your soil and the level of the water table in your area are important issues to research before installing a ground-level trampoline.
