Important Tips for In-Ground Trampoline Installation

Here I’ll give you some important in-ground trampoline installation guidelines so you can build the sunken trampolines perfectly for the proper bounce.

Ensure Good Airflow

Ground-level trampoline safety pad provides airflow in this trampoline. But, it’s not enough to create good jumping. That’s why the mat of the sunken trampoline should be a few inches high from the ground.

This will help good air passing under the trampoline thus you will experience safe and higher bounce. Without enough air escaping, the trampoline won’t give you the right bouncing.

So, the safety pad should ensure proper airflow, as well as the structure, should be quite high (5 to 10 inches) from the earth.

Sunken Trampoline Pit

Sunken trampoline hole preparation is a mandatory task to install the in-ground trampoline. Depending upon, trampoline type, size, soil type, you have to dig the hole and prepare the ground. But, the most important thing is to follow the manufacturer’s guidelines.

While building retaining wall, consider the soil type and trampoline structure. If the trampoline comes with retaining wall kit, follow the manufacturer guideline during installation.

Here is a general guideline to dig sunken trampoline pit.

Water Drainage

While installing low to the ground trampolines, you might need to make water drainage. The drain joins the in-ground trampoline pit and central drain of the backyard. So, stagnant water will pass through the drain easily.

Without proper drainage, rainwater stays in place in the pit even may waterlog the trampoline. This could damage the trampoline mat and springs. Thus, making a good drain while installing an in-ground trampoline hole is important.
