Drainage Solutions for In-Ground Trampolines

Drainage Solutions for In-Ground Trampolines

Many people think that installing an in-ground trampoline is as simple as digging a hole and placing the trampoline structure inside, but that’s simply not the case. Not only do you need to plan for things like retaining walls and ventilation when installing an in-ground trampoline, but you also need to consider how to drain any excess water that might collect inside of your trampoline pit.

Do I Need a Drainage System for an In-Ground Trampoline?

The short answer is yes. Unless you live in an area with a very low water table, there is always a chance that your trampoline hole could fill with water during a storm. Instead of dealing with that scenario when and if it happens, it’s a much better idea to be proactive and create a drainage system when you initially install your sunken trampoline.

Drainage Options for In-Ground Trampolines

There are several ways to accomplish adequate drainage for your in-ground trampoline:

Temporary Drainage Pumps

If you don’t expect to have much rain based on the soil and climate in your area, a temporary type may be the best solution for you. With this solution, all you need is a small drainage pump and an extension cord. Simply plug the pump in, insert the inflow hose into the trampoline pit, switch it on and the excess water will be gone in no time.

Permanent Drainage Pumps

If you foresee water retention as something that could be an ongoing problem under your in-round trampoline, you might consider placing a permanent drainage ump into your pit during the installation process. These pumps go under your trampoline, connect to a permanent electric source, and require you to dig a small trench for the cable and outlet hose. They are typically turned on using a switch in your shed or garage or with a float switch that turns on automatically when the water rises to a certain level.


Often the easiest and most cost-efficient option, this drainage solution only requires you to dig a trench from the bottom of the trampoline pit and connect it to a nearby drainage ditch. After that, you can place a 4” drainage pipe into the trench and watch as water is automatically whisked away. 

Drainage Pits or Soakaway Holes

To implement this drainage solution, all you need to do is dig a small 2’x2’x2’ hole in the center of your trampoline pit and fill it with gravel. This hole, also known as a French drain, will soak up excess water and keep your trampoline pit nice and dry.

Can You Put a Normal Trampoline In the Ground?

Can You Put a Normal Trampoline In the Ground?

Whether your HOA is upset about your existing above-ground trampoline or you’re just looking to make your yard a little more aesthetically pleasing, an in-ground trampoline is a great solution. That said, many parents who already have a normal, above-ground trampoline might be tempted to simply sink it into the ground themselves.

Unfortunately, this is not a good idea. Not only can sinking a normal trampoline into the ground cost you more money than purchasing an in-ground trampoline would, it can also be dangerous. Below are just some of the reasons why you should never bury a regular trampoline in your yard:

  1. They require much more digging. Because of the length of the legs, people who find themselves attempting to sink an above-ground trampoline are also going to find themselves doing a whole lot of digging. According to Capital Play, above-ground trampolines need a hole that’s 40% deeper than an in-ground trampoline would.
  1. They increase the risk of serious injury.
    Burying an above-ground trampoline doesn’t mean it’s as safe as a purpose-built, in-ground trampoline would be. Because you have to dig a significantly deeper hole and you won’t have the benefit of the retaining wall that comes in in-ground trampoline kits, there is a very real possibility that soil will begin to fall down and fill the hole over time. If your child is bouncing and hits the dirt that’s fallen down underneath the trampoline, they could sustain a sprain or broken bone.
    1. They aren’t made to be underground.
      The metal used in above-ground trampolines is designed to be exposed to light and wind, not to be buried in a warm, moist, underground environment. Prolonged exposure to moisture and a lack of airflow can cause an above-ground trampoline frame to rust rather quickly when it’s buried underground.
      1. They are prone to edge collapse. 
        Without proper drainage and retaining wall, there’s no way to prevent the soil underneath your trampoline from shifting over time. This can cause one side of your trampoline to sink over time. It also increases the risk that a bouncer will jump too hard and cause the trampoline to tilt suddenly, throwing them off in the process.

      So you see, by the time you take the necessary precautions and pay for additional digging materials, soil removal, and the materials needed to build a retaining wall and drainage system, you will have almost certainly exceeded the cost of a new, in-ground trampoline.

      Keep your kids safe by going with a trampoline that was built to be used in the ground. Check out Trampoline Superstore’s inventory of in-ground trampolines, nets, and covers, and don’t hesitate to get in touch with us if you have any questions regarding installation
