A Complete Guide to Installing Inground and Flatground Trampolines

Trampolines provide endless fun for children and adults alike, and inground and flatground trampolines offer a safer, more aesthetically pleasing alternative to traditional above-ground models. However, installing these trampolines requires careful planning and execution to ensure safety and longevity. This guide will walk you through the step-by-step process of installing both inground and flatground trampolines in your garden.

Understanding the Difference: Inground vs. Flatground Trampolines

Before starting the installation process, it is essential to understand the differences between inground and flatground trampolines:

  • Inground Trampolines: These trampolines are partially submerged, meaning they sit slightly above the ground with a small gap for airflow. They require a retaining wall or frame to hold the trampoline securely in place.
  • Flatground Trampolines: These trampolines sit completely flush with the ground, offering a seamless appearance and safer entry. They require a more precise excavation and an airflow system for optimal bounce quality.

Planning Your Installation

Before installing your trampoline, consider the following factors:

  1. Choosing the Right Location: Select a level area with adequate clearance from fences, trees, and other obstacles. Ideally, leave at least 2m of space around the trampoline for safety.
  2. Checking Underground Utilities: Ensure there are no pipes, cables, or irrigation systems beneath the installation site.
  3. Assessing Soil Type: Softer soils require additional reinforcement to prevent shifting over time.
  4. Ensuring Proper Drainage: Since the trampoline sits in a hole, ensure water drainage is in place to prevent flooding and mud buildup.

Installing an Inground Trampoline

Step 1: Gather Materials and Tools

Before digging, gather the necessary materials:

  • Trampoline frame and jump mat
  • Springs and safety pads
  • Digging tools (spade, shovel, or mini digger)
  • Tape measure and marking spray
  • Retaining wall materials (optional)
  • Drainage system components (gravel, drainage pipes if needed)

Step 2: Mark and Dig the Hole

  1. Measure and Mark: Mark out the hole dimensions based on the trampoline size. Ensure a slightly wider perimeter for adjustments.
  2. Excavate: Dig a bowl-shaped hole:
    • The outer edge should be slightly shallower (around 40-50 cm deep).
    • The center should be deeper (approximately 75-100 cm) to allow for better bounce and airflow.
  3. Slope the Edges: Ensure smooth, sloped edges to prevent the soil from collapsing.

Step 3: Prepare the Foundation

  1. Install Drainage: If your area has poor drainage, lay down a gravel bed and install perforated drainage pipes leading away from the hole.
  2. Add a Retaining Wall (If Necessary): If your soil is loose, install a retaining wall around the perimeter to prevent collapse.

Step 4: Assemble and Install the Trampoline

  1. Place the Frame: Position the trampoline frame inside the hole and ensure it sits level.
  2. Attach the Springs and Jump Mat: Secure the jumping mat with the springs following the manufacturer’s instructions.
  3. Secure the Padding: Install safety pads over the springs to minimize injury risk.
  4. Test Stability: Ensure the trampoline is level and stable before first use.

Installing a Flatground Trampoline

Step 1: Gather Materials and Tools

For flatground trampoline installation, you will need:

  • Flatground trampoline frame and mat
  • Digging tools (spade, shovel, or mini digger)
  • Tape measure and marking spray
  • Retaining wall materials (if required)
  • Airflow system components (if needed)
  • Leveling tools

Step 2: Mark and Dig the Hole

  1. Measure and Mark: Outline the trampoline size with marking spray or a rope.
  2. Excavate the Hole:
    • The entire area should be excavated to the depth specified by the manufacturer.
    • The bottom of the hole should be completely flat.
  3. Ensure Smooth and Even Walls: The sides of the hole should be vertical to support the trampoline frame.

Step 3: Install the Trampoline Frame and Airflow System

  1. Lay a Solid Base: Place a layer of gravel for drainage if needed.
  2. Install Retaining Walls (If Necessary): To prevent soil collapse, a retaining wall may be required.
  3. Position the Frame: Ensure the frame sits completely flush with the ground.
  4. Attach the Jump Mat and Springs: Follow the manufacturer’s guidelines for secure installation.
  5. Install Airflow Mechanism: Since flatground trampolines sit flush, some models include an airflow system to optimize bounce. Make sure vents or gaps allow for adequate air escape.

Step 4: Final Adjustments

  1. Secure the Safety Padding: Install the protective pads over the frame and springs.
  2. Ensure Even Ground Level: Check that the trampoline is perfectly level with the surrounding ground.
  3. Test the Bounce: Before use, test the trampoline’s bounce to ensure proper functionality.

Post-Installation Maintenance Tips

1. Regular Inspections

  • Check the frame and springs periodically for wear and tear.
  • Tighten bolts and springs as needed.

2. Keep It Clean

  • Remove leaves and debris from the jumping mat.
  • Use a cover during long periods of inactivity.

3. Monitor Drainage

  • Ensure water is not pooling in the hole after heavy rain.
  • Adjust drainage systems if necessary.

4. Safety First

  • Encourage single-person jumping to avoid collisions.
  • Check padding for signs of deterioration.

Conclusion

Installing an inground or flatground trampoline requires careful preparation and proper execution. While inground trampolines offer a slightly raised jumping surface with airflow space, flatground trampolines provide a seamless look with a flush finish. By following the steps outlined in this guide, you can ensure a safe and long-lasting trampoline setup that will provide years of enjoyment for your family.
