Sunken Trampoline problems

Trampolines are a great way to keep kids active and entertained, but sunken trampoline problems can quickly turn that fun into a headache.

From drainage issues to critter control, there are many factors to consider when deciding whether to sink your trampoline into the ground. While it may seem like a good idea to create a seamless look in your backyard, there are several reasons why sinking a traditional trampoline is a bad idea.

For one, the springs can become accessible, leaving your kids vulnerable to injury. Additionally, the cost of sinking your existing trampoline into the ground can really add up, and the end result is often disappointing and unsafe.

In this article, we’ll explore common sunken trampoline problems, their causes, and potential solutions to help you make an informed decision about your backyard setup.

What is a sunken trampoline?

A sunken trampoline is a trampoline that has been installed partially or completely underground. This type of installation is popular because it allows for easier access to the trampoline, and it can also be aesthetically pleasing. However, sunken trampolines can pose a safety risk because the trampoline is not at ground level, which can make it harder to see and avoid.

Identify Major Sunken Trampoline Problems::

Sunken trampolines can cause several problems, including:

i. High installation costs and longer installation time:

Installing a sunken trampoline requires more work and time than an above-ground trampoline. The ground must be excavated, and the hole must be filled with the proper material to provide adequate support. As a result, the installation cost of a sunken trampoline is usually higher than that of an above-ground trampoline.

ii. Ventilation Clearance Issues

Ventilation can lead to reduced bounce, water drainage problems, and hole erosion. A sunken trampoline can have reduced bounce if proper ventilation clearance is not provided. Proper ventilation clearance allows air to circulate under the trampoline, ensuring optimal bounce performance. Without proper ventilation clearance, the trampoline can become waterlogged, causing the trampoline hole to erode and become unstable.

iii. Water Drainage Problems

Potentially causing a waterlogged trampoline hole and erosion. If a sunken trampoline is not adequately drained, it can become waterlogged. This can cause the trampoline hole to erode, leading to instability and safety hazards.

Hole Erosion

Hole erosion is one of the other problems associated with sunken trampolines. It is necessary to ensure that the cavity walls are well structured while digging your hole.

If the walls are not well established, it will cause hole erosion, which can be disastrous in heavy rains.  Therefore, it is necessary to build retaining walls of long-lasting material like cinder, metal sheet or lumber around the hole to avoid hole erosion.

iv. Portability Limitations

As sunken trampolines are more difficult to move: Unlike an above-ground trampoline, a sunken trampoline is more challenging to move because it is fixed in the ground. This can be an issue if you need to move the trampoline for any reason, such as landscaping or moving to a new house.

v. Critter Control

Sunken trampolines can attract animals, including rodents and insects, which can cause damage to the trampoline and create a potential safety hazard. The use of Citter control can help get rid of this issue.

vi. Safety Concerns

A sunken trampoline can pose safety concerns, such as exposed springs, tripping hazards, and an increased risk of injury due to the trampoline not being at ground level. It’s important to take proper safety precautions, such as installing a safety net and padding, to reduce the risk of injury.

Causes of Sunken Trampolines Sinking

Several factors can cause a trampoline to sink, including:

i. Poor Installation

If the sunken trampoline is not installed correctly, it can sink over time due to the weight of the trampoline and the people using it. This can be a significant safety hazard, as a sinking trampoline can cause injuries or damage to the trampoline.

ii. Soil Erosion

Soil erosion can be a result of heavy rainfall, water runoff, or even wind. If the soil around the trampoline erodes or washes away, it can cause the trampoline to sink. Proper drainage and landscaping can help prevent soil erosion and prolong the life of the trampoline.

iii. Heavy Rainfall

Heavy rainfall can cause the soil around the sunken trampoline to become saturated, leading to sinking. This can be especially problematic if the trampoline is installed in a low-lying area or if the soil is not well-draining. In areas with heavy rainfall, it’s important to ensure proper drainage and avoid installing the trampoline in a spot that is prone to flooding.

iv. Natural Settling

Over time, the soil around the trampoline can naturally settle, causing it to sink. This can happen regardless of the quality of the installation or maintenance of the trampoline. Regularly inspecting the trampoline and the surrounding area can help identify sinking before it becomes a significant safety hazard. In some cases, the trampoline may need to be re-leveled or even relocated to prevent further sinking.

Prevention of Sunken Trampolines

There are several things you can do to prevent your trampoline from sinking, including:

i. Proper Installation

The first and most crucial step to preventing a sunken trampoline is to ensure proper installation. Make sure that you follow the manufacturer’s instructions carefully and accurately. It is essential to have a level surface for your trampoline, and you should avoid installing it on slopes or uneven ground. The site where the trampoline is to be installed should be free of debris and vegetation.


ii. Regular Maintenance

Regular maintenance is also important to prevent sunken trampolines. Ensure that the trampoline is kept clean and check for any signs of wear and tear, including rust, tears, and broken parts. Repair or replace any damaged parts immediately. Regular maintenance will help extend the life of your trampoline and prevent it from sinking.

iii. Proper Drainage

Ensure proper drainage around the trampoline to prevent water accumulation. Water accumulation around the trampoline can cause the soil to become saturated and sink. To prevent this, install a drainage system or ensure that the area around the trampoline has adequate drainage. This will keep the soil dry and prevent it from sinking.

iv. Use a Trampoline Cover

Using a trampoline cover is another effective way to prevent a sunken trampoline. The cover will protect the trampoline from water and debris, reducing the risk of damage. A trampoline cover will also keep the trampoline clean and dry, which will help to prevent the soil around it from becoming saturated and sinking.

v. Considering Portability and Garden Aesthetics

If you are concerned about the trampoline sinking in the future, you may want to consider using a portable trampoline or placing the trampoline on a raised platform. Additionally, landscaping around the trampoline can help improve drainage and prevent soil erosion.

vi. Preparing for Monsoon Season with Proper Drainage Options

In areas with heavy rainfall or monsoon seasons, it is important to implement proper drainage options such as a sump pump or a rain barrel to prevent the soil from becoming saturated and causing the trampoline to sink.

Comparison of Inground Sunken trampoline vs Above ground trampolines

Here is a comparison between in-ground sunken trampolines and above-ground trampolines that will help you choose the ideal option for your family’s entertainment while emphasizing safety features and aesthetics.

Balance Between Style and Safety

Trampolines sunk in the ground offer safety and stability, particularly for young kids. Above-ground trampolines are less integrated into landscaping but are more portable due to their elevated position on a frame. Make your decision depending on your aesthetic and safety preferences.

Cost considerations

Above-ground trampolines are more affordable, requiring less money for setup and installation. They provide a more cost-effective solution than sunken trampolines, making them perfect for small locations.

Easy Maintenance

 Regular cleaning and maintenance are necessary for in-ground trampolines, which require more care than their above-ground counterparts. Above-ground trampolines are a reasonable option for frequent usage because they have fewer moving parts and are thus simpler to maintain.
