In Ground Trampoline: Costs and How To Build an Underground Trampoline

Some people think that trampolines are only available to sit on top of the ground in their yard. This can cause people to worry about all the risk involved in owning a trampoline and when combined with the bulkiness of having one in their yard, may prevent them from enjoying one of the best ways to enjoy daily exercise. Now, there is a better way to enjoy jumping on a trampoline. An in ground trampoline is safer than traditional trampolines and according to many people, much nicer to look at in their yard.

What is an In Ground Trampoline?

An in ground trampoline is a trampoline that has the frame buried under the surface in a hole. It has the same support as an above ground, traditional trampoline, but there is less risk of kids falling off of it while playing. It is also more appealing to see a sunken trampoline in the yard instead of having a metal frame that stands out.

Some sunken trampolines are designed specifically for in ground use, that is, they come with the necessary parts/supports for in ground installation. They have heavier duty steel and some may have walls rather than legs for you to bury. These trampolines are significantly more expensive in some cases, depending on what type of trampoline you want. This has led to many people choosing the DIY underground trampolines instead, where you simply lower your trampoline into a pit.

Are In Ground Trampolines Safer?

A misconception we hear is that in ground trampolines are safer. If there’s no safety net the chances of a kid hurting him or herself is just as great as an above ground trampoline. If any child falls from 5 feet or more onto the hard ground there is a chance for injury. Also the hole where your trampoline sits in the ground needs to be bigger than your trampoline so it gets proper ventilation. This provides a gap where feet and hands could get caught in, which could lead to a severe injury.

In Ground Trampoline Costs

An underground trampoline will cost you a lot more money than an above ground trampoline. If you are really concerned with the atheistic looks of a trampoline in your backyard or live in a high wind area which could damage your trampoline maybe you should go the in ground route. There are some trampolines that come with the retaining wall which all are above $1000. For people going the DIY route you can buy the materials for a retaining wall which can cost as much as a trampoline depending on which one you buy. Then you have to factor in the time and costs to dig the hole. In the end a sunken trampoline will likely cost two to three times more than an above ground trampoline.

In Ground Trampoline Installation

Learning how to put a trampoline in the ground is not hard. Often, even the DIY type project is only a complicated process during the planning and digging stage. The rest of the assembly can mostly be completed within a couple hours. You simply plan out and dig your hole, set the already assembled trampoline into it, and put back some of the dirt to help support the trampoline. Please remember to dig a hole large enough so there’s a gap between the edge of the trampoline and the retaining wall. Without this gap the air will not be properly ventilated and the jumping surface will feel harder. This will lead to kids not being able to jump as high.
