How to Install an Inground Trampoline: A Guide for Parents - OutdoorToys

Ready to make your garden the coolest spot in the neighbourhood? Installing an inground trampoline is a fantastic way to get your kids outside, active, and having a blast - because everyone knows every bounce on a trampoline is a leap into fun.

Why choose an inground trampoline?

Health benefits for kids

  • Physical exercise: Trampolining is an excellent form of exercise. It helps improve cardiovascular health, strengthens muscles, and enhances coordination and balance.
  • Mental health: Jumping on a trampoline releases endorphins, which can help improve mood and reduce stress.
  • Motor skills: Regular trampoline use helps develop motor skills and body control.
  • Bone density: The repetitive bouncing motion helps improve bone density, which is essential for growing kids.

Advantages of inground trampolines

  • Aesthetics: An inground trampoline blends seamlessly into your garden, unlike above-ground trampolines, which can be bulky and obtrusive.
  • Safety: An inground trampoline significantly reduces the risk of falls from a height, making it a safer option, especially for younger children.
  • Space efficiency: Inground trampolines are flush with the ground, allowing for more efficient use of space in your garden.
  • Ease of access: Kids and adults can easily get on and off the trampoline without needing a ladder or steps.

Step-by-step guide on how to install an inground trampoline

In this guide, we've covered everything you need to know about installing an inground trampoline, from digging the hole to attaching the trampoline mat.

Grab your spades, and let's get started!

Materials and tools needed

Before you begin, ensure you have all the necessary materials and tools:

  • Inground trampoline kit (frame, trampoline mat, springs)
  • Retaining wall materials
  • Spray paint
  • Spades and digging tools
  • TDU vented pads (optional for enhanced airflow)
  • Safety net
  • Measuring tape

Step 1: Choose the location

Select a flat area in your garden, free from tree roots and hard surfaces. Ensure there is ample space around the trampoline for safe play. Measure and mark the area using spray paint.

Step 2: Dig the hole

Here’s how to dig the hole for your inground trampoline:

  1. Dimensions: The hole should be slightly wider than the trampoline frame. Check your trampoline's manual for the exact dimensions.
  2. Bowl shape: Dig the hole in a bowl shape, with the centre being the deepest point. This shape helps with drainage and provides optimal bouncing conditions.
  3. Required depth: The depth will depend on your trampoline's size. Larger trampolines will need deeper holes. Ensure the hole is at the correct height for the trampoline frame to flush with the ground.
  4. Entire hole: Dig out the entire hole, ensuring it matches the required dimensions.

Step 3: Install retaining walls

To prevent the sides of the hole from collapsing, install retaining walls around the perimeter. This step is crucial for maintaining the integrity of your inground trampoline. Use materials like treated wood, metal, or specially designed retaining wall blocks.

Step 4: Set up drainage

Proper drainage is essential to prevent water from accumulating in the trampoline pit. If your area is prone to heavy rain or poor drainage, install a sump pump* at the bottom of the hole. This will help keep the trampoline area dry and safe. Or, instead of installing a sump pump, you could build a soakaway. A soakaway is a pit filled with a combination of stone, shingle or brick and helps any rainwater drain away.

At the bottom of the hole for the trampoline, build a pit approximately 600 x 600 x 600 and fill it with the above.

Step 5: Assemble the trampoline frame

Follow the manufacturer’s instructions to assemble the trampoline frame. Place it into the hole, ensuring it sits at ground level. Check that the frame is level and secure before moving on.

Step 6: Attach the trampoline mat and springs

This step requires some muscle, but it’s worth it!

Use the springs to attach the trampoline mat to the frame. Make sure the tension is even around the entire trampoline to ensure a smooth and safe bounce.

Step 7: Backfill around the trampoline

Carefully backfill the space around the trampoline frame with soil, ensuring there are no gaps. This will keep the trampoline stable and secure. Make sure the soil is compacted well to prevent any settling.

Step 8: Install TDU vented pads

Consider adding TDU vented pads around the trampoline for extra safety and comfort. These pads help with airflow and provide additional cushioning, making the trampoline more comfortable to use.

Step 9: Add a safety net

If you want extra protection for your kids, install a safety net around the trampoline. This step is especially important for younger children, providing an added layer of safety.

  • Backfilling: Ensure the backfilling is done properly without leaving any gaps that could cause instability.
  • Top layer: To blend the trampoline with your garden and enhance its appearance, add a top layer of turf or soft padding around it.
  • Test the trampoline: Before letting the kids jump, test it to ensure it is secure and provides an even bounce.

Additional tips and tricks for a smooth installation

When installing your inground trampoline, a few additional tips and tricks can make the process smoother and ensure a better end result.

First, calculate how much soil you'll need to backfill around the trampoline frame, always erring on the side of having a little extra to ensure complete coverage. It's also wise to dig the hole a few inches deeper than the required depth to account for soil settling over time, ensuring that your trampoline remains at the correct height.

Proper installation requires that the trampoline frame sit flush with the ground, both for safety and aesthetic reasons. By paying attention to these details, you'll create a safe and durable play area that your kids will love for years to come.

FAQs about installing an inground trampoline

What do you put under an inground trampoline?

Under an inground trampoline, you typically install a drainage system to prevent water accumulation. Additionally, you might place a layer of gravel or sand at the bottom to facilitate drainage and provide a stable foundation.

Do in-ground trampolines need drainage?

Yes, in-ground trampolines need proper drainage to prevent water from pooling in the pit. Installing a sump pump or creating a gravel drainage layer can effectively manage water and keep the area dry and safe.

How do you prepare the ground for a sunken trampoline?

To prepare the ground for a sunken trampoline, start by marking the area and digging a hole with a bowl shape. Install retaining walls to support the sides, add a drainage layer to manage water, and ensure the hole is the correct depth and dimensions for the trampoline frame.

Can you put a normal trampoline underground?

You can put a normal trampoline underground, but it requires additional modifications. You’ll need to ensure proper drainage, support the sides with retaining walls, and adjust the trampoline frame to sit at ground level, ensuring safety and stability.
