No, it is generally not recommended or safe to install a regular trampoline directly in the ground.
Why Burying a Regular Trampoline is Not Recommended
Attempting to install a standard above-ground trampoline by burying it presents significant safety and structural issues. The primary reason lies in the fundamental design of regular trampolines compared to those specifically made for in-ground installation.
Frame Deterioration and Safety Risks
One of the critical differences is the frame material and treatment. Metal frames used in regular trampolines are not intended to be buried underground. These frames are typically designed for exposure to air and are not treated or constructed to withstand constant contact with soil moisture.
- Moisture and Rust: When buried, the metal frame is continuously exposed to moisture from the surrounding earth. This environment accelerates rusting and corrosion.
- Structural Weakness: Over time, moisture and rust will cause the frame to deteriorate and break. A weakened or broken frame poses a severe safety hazard.
- Risk of Injury: One does not want to tumble onto a broken trampoline. The structural failure of the frame while someone is using it can lead to serious injuries.
Installation Challenges
Beyond the frame issues, attempting to sink a regular trampoline also creates practical installation difficulties:
- Deep Excavation: The hole needed to sink a normal trampoline is deep to accommodate the frame and the necessary air displacement for bouncing.
- Retaining Wall: It must be supported with a retaining wall to prevent the surrounding soil from collapsing into the pit, which adds complexity and cost to the installation.
In contrast, purpose-built in-ground trampolines feature frames made from materials better suited to subterranean conditions (like galvanized steel with thicker coatings or alternative materials) and often have integrated venting systems to manage air displacement during bouncing without requiring such extensive pits and retaining walls.
Therefore, for safety, durability, and ease of installation, it is best to use a trampoline specifically designed for in-ground placement if you wish to have a trampoline flush with the ground level.
