Preparing for Installation

Site Selection

Choosing the right location for your in-ground trampoline is crucial. Ensure the area is flat and free from obstacles like tree roots or rocks. It should also be easily accessible for kids and adults alike.

Pro Tip: Avoid areas with heavy shade to prevent moss and mildew from forming on the trampoline.

Measuring

Accurate measurements are essential for a successful installation. Start by measuring the diameter and depth of the trampoline. Add an extra 2-5 inches to your outline to make placing the frame easier.

Example: For a 14′ Avyna trampoline, the outer hole should be 14′ in diameter and 9″ deep. The inner hole should be 12’8″ in diameter and 36″ deep.

Tools Needed

Gather all necessary tools before you start. Here’s a handy checklist:

• Excavator or shovel
• Spray paint for marking the dig area
• Level for ensuring the frame is even
• Measuring tape for accurate dimensions
• Tin snips for cutting materials
• Two wrenches that fit the bolts and nuts
• Hammer and drill
• Pencil/Pen for marking
• Extra 2×4 or 1×2 to set the level on

Having these tools ready will make the process smoother and quicker.

Let’s move on to the next step: Choosing the Right Location.

How to Install an In-Ground Trampoline

Choosing the Right Location

Selecting the perfect spot for your in-ground trampoline is crucial. Here are some factors to consider:

• Accessibility: Ensure the trampoline is easily accessible for all users. Avoid placing it in a hard-to-reach corner of your yard.
• Sunlight: Position the trampoline where it gets a good amount of sunlight, but also consider some shade to avoid overheating the jumping mat.
• Drainage: Choose a location with good natural drainage to prevent water from pooling under the trampoline.

Pro Tip: If your yard has poor drainage, you might need to install a drainage system. This could involve laying gravel or installing drainage pipes.

Digging the Hole

Here’s where the real work begins. The hole needs to be the right depth and width for your trampoline.

• Depth: The depth varies based on the trampoline model. For example, a TDU trampoline requires a depth of 36 inches for the inner hole.
• Width: Make sure the hole is slightly larger than the trampoline frame. This extra space helps with installation and backfilling.
• Soil Type: Sandy and porous soils drain well, while clay soils may require additional drainage solutions.

Steps to Dig the Hole:
1. Mark the Area: Use spray paint to outline the area where you’ll dig. Add 2-5 inches around the frame for easier placement.
2. Remove Turf: Save some turf to backfill later.
3. Dig the First Hole: This is the outer hole. Use a measuring tape to ensure consistent depth.
4. Dig the Second Hole: This is the inner hole, also known as the bowl area. The sides should slope inward.

Setting Up the Frame

Once the hole is ready, it’s time to set up the trampoline frame.

• Assembly: Start by partially assembling the frame above ground. This helps you mark the dig area accurately.
• Positioning: Place the frame into the hole. Ensure it’s level using a 2×4 and a level tool.
• Securing: Attach the retaining walls to the frame. Use a drill and screws to secure them tightly.

Pro Tip: Use two wrenches to tighten bolts and nuts. This ensures the frame is secure and stable.

With these steps, you’re well on your way to mastering how to install an in-ground trampoline. Next, we’ll discuss ensuring safety and stability, focusing on retaining walls, backfilling, and ground leveling.

Ensuring Safety and Stability

Installing Retaining Walls

To ensure the longevity and safety of your in-ground trampoline, retaining walls are essential. These walls prevent soil from collapsing into the hole and provide structural support. Here’s how to install them:

1. Materials: Use high-quality materials like metal panels or specially designed retaining wall blocks. Avoid wood, which can rot, or low-quality materials that may fail over time.
2. Techniques:
3. Begin by placing the retaining wall materials around the perimeter of the hole.
4. Secure each panel or block to the trampoline frame using screws and bolts. Use a drill for precise and tight fastening.
5. Ensure the walls are flush with the ground and level. This helps in providing even support and prevents any gaps where soil could seep through.
6. Stability:
7. Double-check that every section of the retaining wall is firmly in place.
8. Use a level tool frequently to ensure the walls are straight and even.
9. For additional stability, you can reinforce the walls with stakes driven into the ground at intervals.

Pro Tip: If working on a slope, you may need to dig a trench to make the ground level before installing the retaining walls. This will provide a stable base.

Backfilling and Compacting

Once the retaining walls are in place, the next step is backfilling the space between the walls and the original soil. This process involves filling the gap with soil and compacting it to ensure stability.

1. Methods:
2. Slowly add soil back into the gap, a few inches at a time.
3. Use a shovel or small backhoe for even distribution.
4. Materials:
5. Use the soil you originally dug out, if it’s suitable. If not, use good quality fill dirt.
6. Avoid using clay or other materials that don’t compact well or could cause drainage issues.
7. Compaction Techniques:
8. After adding each layer of soil, use a tamper or plate compactor to compact it.
9. Compacting the soil in layers helps prevent settling and provides a firm base for the trampoline.

Pro Tip: Avoid getting soil inside the trampoline area. This can be done by covering the trampoline with a tarp during the backfilling process.

Ground Leveling and Preparation

The final step before you can start jumping is to ensure the ground around and inside the trampoline is level and well-prepared. This will make the trampoline safer and more enjoyable.

1. Leveling Tools:
2. Use a long 2×4 and a level tool to check for evenness.
3. A laser level can also be handy for larger areas.
4. Techniques:
5. Start by leveling the area immediately around the trampoline.
6. Fill any low spots with soil and compact it well.
7. If using synthetic turf, lay it down and secure it properly to avoid any wrinkles or uneven spots.
8. Final Checks:
9. Walk around the trampoline to ensure the ground feels firm and level.
10. Check the trampoline frame and retaining walls one last time for stability.
11. Make sure all screws and bolts are tight, and there are no loose parts.

Pro Tip: Consistently check for any signs of soil erosion or settling over time, especially after heavy rain. Early detection can prevent bigger issues down the line.

By taking these steps, you’ll ensure your in-ground trampoline is safe and stable for years of fun. Next, we’ll cover adding the fun and functional elements like springs, the jumping mat, and protective pads.

Attaching the Springs

Attaching the springs is the first step in making your trampoline bouncy and fun. If you’re installing a rectangular trampoline, start by attaching springs at the four corners and then at the middle of each side. This ensures the tension is evenly distributed.

Pro Tip: Work in opposites with a partner to maintain even tension. For example, if you attach a spring at the top right corner, your partner should attach one at the bottom left.

Safety Checks:
– Ensure each spring is securely attached to both the frame and the mat.
– Check for any signs of rust or wear on the springs before use.

Laying the Jumping Mat

Next, lay the jumping mat inside the frame. Make sure it is centered and aligned properly. Attach the mat to the springs, starting again with the corners and then the middle of each side.

Pro Tip: Use a spring tool or a hook to make attaching the springs easier and safer.

Safety Inspection:
– Ensure the mat is taut and evenly stretched.
– Check for any tears or weak spots on the mat.

Installing Protective Pads

Finally, install the protective pads around the trampoline. These pads cover the springs and frame, reducing the risk of injury.

Types of Pads:
– Standard Pads: Basic protection, usually made of foam and vinyl.
– Premium Pads: Thicker and more durable, often with UV protection.

Installation Tips:
