Benefits of In-Ground Trampolines

In-ground trampolines offer several advantages over their above-ground counterparts:

Increased Safety

With their lower height, in-ground trampolines reduce the risk of injuries from falls. This makes them especially suitable for families with young children or those concerned about safety.

Aesthetics and Space Saving

In-ground trampolines blend seamlessly into your yard, making them more visually appealing. They also save space, as they don’t require the additional clearance needed for above-ground trampolines.

Step by Step Guide to Install an In-Ground Trampoline

Follow these steps to install your in-ground trampoline:

Step 1: Choose the Right Location

Select a flat area in your backyard, free of obstructions and potential hazards like trees, rocks, or fences. Make sure there’s adequate space around the trampoline for safe jumping.

Step 2: Purchase a Suitable Trampoline

Invest in a high-quality, in-ground trampoline specifically designed for this purpose. These trampolines usually have a galvanized steel frame and rust-resistant springs to withstand underground conditions.

Step 3: Gather the Necessary Tools

You’ll need the following tools for the installation:

  • Shovel
  • Measuring tape
  • Level
  • Stakes and string
  • Tarp or wheelbarrow (to hold the dirt)
  • Landscaping fabric
  • Gravel
  • Sand
  • Water

Step 4: Dig the Hole

Mark the trampoline’s circumference using stakes and string. Then, dig a hole slightly wider than the trampoline and about 3 feet deep, depending on the model’s specifications.

Step 5: Prepare the Ground

Ensure the bottom of the hole is level and compact the soil. Lay landscaping fabric on the bottom to prevent weed growth, and then add a layer of gravel for drainage.

Step 6: Assemble the Trampoline

Assemble the trampoline according to the manufacturer’s instructions. Ensure the frame is level, and attach the jumping mat and springs.

Step 7: Install Drainage System

A proper drainage system is essential to prevent water buildup and potential damage to the trampoline. Dig a trench leading away from the hole and fill it with gravel. Next, lay perforated drainage pipe along the trench and cover it with more gravel. This will help divert water away from the trampoline.

Step 8: Backfill the Hole

Carefully backfill the hole with a mixture of soil and sand, making sure not to damage the trampoline frame or springs. Tamp down the soil firmly around the trampoline to provide stability and prevent future shifting.

Tips for Maintaining Your In-Ground Trampoline

Proper maintenance is crucial for ensuring the longevity and safety of your in-ground trampoline. Follow these tips:

Regularly Inspect the Trampoline

Check the springs, frame, jumping mat, and other components for signs of wear or damage. Replace any damaged parts immediately to prevent injuries.

Keep the Area Clean

Remove leaves, branches, and other debris from the trampoline surface and surrounding area. This prevents mold, mildew, and potential damage to the trampoline materials.

Properly Winterize Your Trampoline

If you live in an area with harsh winters, consider disassembling and storing the trampoline indoors to protect it from the elements. Alternatively, you can invest in a weather-resistant cover to shield it from snow and ice.

Frequently Asked Questions

Is an in-ground trampoline more expensive than an above-ground trampoline?

In general, in-ground trampolines tend to be more expensive due to the additional installation costs, such as excavation and drainage systems. However, the safety and aesthetic benefits often outweigh the extra expense.

Do in-ground trampolines require professional installation?

While professional installation is an option, many homeowners choose to install their in-ground trampolines themselves. Just follow the step-by-step guide provided in this article, and you should be able to complete the installation successfully.

Can I convert my existing above-ground trampoline into an in-ground trampoline?

It’s possible, but not recommended. Above-ground trampolines are not specifically designed for in-ground use and may not have the necessary rust-resistant materials or proper drainage systems.

What should I do if water collects in the trampoline hole after heavy rain?

If you have a properly installed drainage system, water should not accumulate in the hole. However, if water does collect, you may need to reevaluate your drainage system and make necessary adjustments to prevent future issues.

How often should I inspect and maintain my in-ground trampoline?

Regular inspections and maintenance are key to the longevity and safety of your trampoline. Inspect your trampoline at least once a month during peak usage and more frequently if you notice any issues.
