Steps To Put a Trampoline on Unlevel Ground

Steps To Put a Trampoline on Unlevel Ground

1. Evaluate the Ground

Before you start digging or shimming, you need to assess the slope of the ground.

Grab your level tool and let’s get to work!

Using your level tool, check the slope of the ground and identify the high and low points.

Now, if the slope is more than 2 inches, my friend, it’s time to level up or move along.

However, if the slope is less than 2 inches, we can use shims or build a retaining wall to level the trampoline.

Ah, but what the heck are shims and retaining walls, you ask? Keep reading, my dear jumpers.

Level the Ground

Now comes the fun part: leveling the ground.

As someone who’s had their fair share of bouncy mishaps, trust me, you don’t want to skip this step.

First, mark the area where you want to install the trampoline using stakes and string.

This will help you stay on track and avoid any unnecessary digging.

Now, remove any rocks, debris, or plants from the area.

The last thing you want is to bounce into a prickly cactus.

Use a shovel or tiller to loosen the soil and remove any high spots.

Remember, we want a nice, flat surface to bounce on.

Add new soil or sand to the low spots until the ground is level.

Now, this is where things can get a bit perplexing.

How do you know if the ground is level?

Well, you can use your level tool, or you can use your feet to feel for any unevenness.

Finally, use a plate compactor or a hand tamper to tamp the soil down.

Tamping may not be the most glamorous part of the process, but it’s crucial for keeping the ground level and preventing any sinkholes from forming.

Build a Retaining Wall

Now, what if your unlevel ground has more than a 2-inch slope?

Fear not, because you can still put your trampoline up with a retaining wall.

Here’s how to build one: first, mark the area where you want to install the trampoline using stakes and string.

Next, dig a trench around the perimeter of the area, about 6 inches deep.

This trench will be the foundation for your retaining wall.

Insert landscape timbers or retaining wall blocks into the trench, making sure they’re level.

  • If you’re using timbers, stack them on top of each other and stagger the seams to give your wall more stability.
  • If you’re using blocks, make sure they interlock and are secured in place with adhesive.

Once you’ve inserted the timbers or blocks, backfill the trench with soil or gravel, and tamp it down.

Finally, add a layer of sand or gravel on top of the retaining wall to create a flat surface.

This will be the base for your trampoline.

Voila, you now have a level ground for your trampoline to safely bounce on.

Now, that wasn’t so hard, was it?

But what if you don’t want to build a retaining wall?

No worries, my bouncy friends, because there’s another way to level your trampoline on unlevel ground.

Use Shims

If your unlevel ground has a slope of less than 2 inches, you can use shims to level the trampoline.

Shims are small, wedge-shaped pieces of material that you can place under the legs of the trampoline to make it level.

Here’s how to use them:

  • First, determine the height of the low point by using a level tool.
  • Once you’ve identified the low spot, cut a piece of pressure-treated lumber to fit. Make sure the shim is thick enough to raise the trampoline to the desired level.
  • Next, place the shim under the leg of the trampoline that’s on the low spot. Use your level tool to check if the trampoline is level. If it’s not, adjust the shim as needed until the trampoline is level.
  • Repeat the process for the other legs of the trampoline until it’s level all around.

Now, you may be wondering, what kind of material can I use for shims?

Well, you can use anything from wood shims to rubber mats to achieve the desired level.

Secure the Trampoline

Now that your trampoline is level, it’s time to secure it to the ground.

This step is essential to prevent the trampoline from moving or tipping over during use.

Here’s how to do it:

  • First, attach the trampoline legs to the frame using bolts or screws. Make sure they are tight and secure, as this will provide the foundation for anchoring your trampoline.
  • Next, use an anchor kit to secure the trampoline to the ground. Anchor kits come in various forms, such as corkscrew-shaped anchors or strap-based systems. The type of kit you choose will depend on the soil type and weight of your trampoline.
  • Make sure the anchor kit is compatible with the soil type and weight of the trampoline. For instance, if you have rocky or hard soil, you may need heavier-duty anchors. Similarly, if you have a larger or heavier trampoline, you’ll need a stronger anchor kit.
  • Follow the manufacturer’s instructions for installing the anchor kit. This will ensure that the kit is installed correctly and will provide maximum safety and security for your trampoline.
  • Finally, test the trampoline to make sure it’s secure before using it. Give it a good shake and make sure it doesn’t move or wobble. Jump on it a few times to make sure it’s stable and doesn’t tip over.

Congratulations, my bouncy friends, you have successfully put your trampoline on unlevel ground!

Now, go forth and bounce with confidence, knowing that your trampoline is safely secured to the ground.

But remember, safety always comes first, so make sure to follow all the necessary precautions when using your trampoline. Happy bouncing!

Frequently Asked Questions (FAQs)

Can I use sand to level the ground for my trampoline?

Yes, you can use sand to level the ground for your trampoline. Just make sure you use enough sand to fill in the low spots, and tamp it down to create a stable base.

Can I build a retaining wall using bricks?

Yes, you can use bricks to build a retaining wall. Just make sure the bricks are interlocking and secured in place with adhesive. Backfill the trench with soil or gravel, and tamp it down to create a solid foundation.

How do I know if the anchor kit is compatible with my trampoline?

To know if the anchor kit is compatible with your trampoline, check the weight and size specifications of the anchor kit and compare them with the weight and size of your trampoline. Make sure the anchor kit can hold the weight of your trampoline and is suitable for the soil type in your area.

How often should I check the anchor kit of my trampoline?

It is recommended to check the anchor kit of your trampoline at least once a month, especially after a storm or strong winds. Make sure the anchor kit is still secured to the ground and the bolts or screws are tight.

Can I use foam as shims to level my trampoline?

No, foam is not a suitable material to use as shims for leveling your trampoline. It is not strong enough to support the weight of the trampoline and can compress over time, leading to instability. Use pressure-treated lumber or rubber mats instead.

In Conclusion: How to Put a Trampoline on Unlevel Ground?

Putting a trampoline on unlevel ground may seem like a daunting task, but with a little perseverance and creativity, you can do it!

Whether you choose to level the ground, build a retaining wall, or use shims, always remember to prioritize safety and have fun bouncing!
