Hey all

So I was in talks this evening with a friend who was asking me about in-ground trampolines and what it would take. Has anyone here done this? I’m assuming it’s a full size residential round trampoline, so a hole would need to be about 3-4’ deep? I’m not sure at what height retaining walls come into play. Any insight or help is appreciated.

Thank you

Steve

Not sure but I would think a french drain for the hole would be needed!

Sounds like an interesting project, I'd be concerned with how much stuff would "fall" including rodents into the hole, causing a pain to remove. Before anything confirm that his home owners insurance doesn't have an exclusion.

I remember as a kid there was a place that had a number of in ground trampolines, and they were fun. Better and probably safer than the ones that are up off the ground.

Still...I can't imagine a place like I remember being in business today.

I agree with the drain idea. Who wants a mosquito pit?

Right, so the water collection would be the biggest thing. But being southern NJ, it’s very sandy pine barren type soil. I would have to figure that digging below the necessary depth, putting a gravel pit, with sump pump, would most likely address that issue.

And upon quick research, in-ground trampolines are sold as kits themselves. Interesting.

Then my next concern is, the cost of all of this, for a trampoline…..Hey, not my money.

I did one for my grandkids. It is on a slight incline, so I only had to take down part of the hill. It's pretty dry where I live, but we've had no issue with runoff. We raised the area around the front to eliminate almost all of the height and provide a level area and saved the dirt for another project. I reinforced the upper side of the hill with OSB.

We did an 8 ft diameter stock tank "pool" the same way except no reinforcement of the pool was required.
