Inground trampolines have surged in popularity as a stylish and safer alternative to traditional above-ground trampolines. Installed flush with the surrounding ground, these trampolines provide a sleek, minimalist appearance, enhanced safety features, and significantly reduced fall risks. However, proper installation requires thorough planning, effort, and attention to detail. This comprehensive guide covers everything you need to know about inground trampoline installation, including the step-by-step process, associated costs, key benefits, and expert tips for a successful setup.
What Is an Inground Trampoline?
An inground trampoline is a trampoline that is installed level with the ground, with its jumping surface flush with the lawn or soil around it. Unlike traditional above-ground trampolines that sit elevated on legs, inground models are recessed into a dug hole. This innovative design improves backyard aesthetics, enhances user accessibility, and significantly lowers the risk of injuries due to falls.
Benefits of Inground Trampolines
- Enhanced Safety
By eliminating the trampoline’s elevated height, inground models greatly reduce the risk of falls and associated injuries. - Attractive Design
These trampolines integrate seamlessly into your outdoor space, maintaining an unobtrusive and neat landscape appearance. - Improved Accessibility
Ground-level entry makes it easier for children, seniors, and individuals with mobility challenges to use the trampoline comfortably. - Durability and Stability
Proper installation ensures inground trampolines are less susceptible to tipping over or damage from strong winds, providing a stable and long-lasting recreational feature.
Steps for Installing an Inground Trampoline
Installing an inground trampoline involves several detailed steps that require precision and care. Here’s an optimized installation process:
1. Choose the Ideal Location
Select a suitable spot based on the following criteria:
- Flat and Level Surface: Choose a flat area to reduce excavation work and ensure stability.
- Efficient Drainage: Avoid low-lying or flood-prone zones. Proper drainage prevents water accumulation beneath the trampoline.
- Clearance Space: Leave a 3–5-foot buffer zone free from trees, fences, or other obstructions to provide a safe jumping environment.
2. Select a Trampoline Designed for Inground Use
Opt for trampolines specifically engineered for inground installation. These models typically feature vented pads for water drainage and reinforced frames. Common shapes include round, rectangular, and oval designs.
3. Excavate the Hole
Digging the hole is the most demanding stage.
- Mark the Dig Site: Place the trampoline frame on the ground as a stencil to outline the digging area precisely.
- Proper Dimensions: Excavate a hole matching the trampoline’s base, usually 3–4 feet deep at the center with slightly sloped sides for structural stability.
- Digging Approach: Choose between manual digging with shovels or hiring professional excavators for a faster, more precise job.
4. Establish Effective Drainage
Prevent water buildup by incorporating drainage solutions such as:
- Installing a French drain or sump pump system below the trampoline.
- Laying a crushed gravel base at the bottom of the hole for improved water percolation.
- Ensuring proper grading so soil slopes away from the trampoline pit.
5. Assemble the Frame
Construct the trampoline frame within or above the pit, following the manufacturer’s guidelines for secure assembly and ensuring the frame sits flush with the ground.
6. Attach the Jumping Mat and Springs
Connect the mat to the frame using springs, making sure they’re evenly spaced and tightly secured to provide consistent bounce and performance.
7. Backfill and Secure the Edges
Fill the gaps around the frame with compacted soil to lock the trampoline into place and prevent shifting over time.
8. Add Safety Features
Install protective vented pads over springs and frames to reduce injury risks. Optional enclosure nets add an extra layer of safety, especially for children.
Costs of Inground Trampoline Installation
Costs vary widely depending on trampoline size, installation complexity, and accessories.
- Trampoline Purchase: $450–$3,000, varying by size, shape, and manufacturer.
- Excavation Services: $600–$1,800 if outsourced; DIY options reduce costs but require physical labor.
- Drainage Installation: $150–$600 for materials and professional setup.
- Safety Accessories: $150–$400 for pads, nets, and related equipment.
Typically, a full inground trampoline installation ranges between $1,200 and $4,500.
Maintenance Tips for Inground Trampolines
- Regular Inspections: Frequently check the frame, springs, and jumping mat for wear, corrosion, or damage and replace components promptly.
- Clean Debris: Keep the trampoline surface and drainage areas free from leaves, dirt, and other debris that could hinder performance or drainage.
- Monitor Drainage Efficiency: After heavy rainfall, verify that water drains properly and address any pooling immediately.
- Protective Covering: Use a weather-resistant cover during off-season or severe weather to minimize UV damage and extend the trampoline’s lifespan.
Final Thoughts
Installing an inground trampoline can transform your backyard into a fun and safe recreational area while enhancing its visual appeal. Although the installation demands time, labor, and investment, the long-term benefits—improved safety, durability, and seamless integration into your landscape—are well worth the effort.
