Can You Put Trampolines on Uneven Ground?

Trampolines need level ground for safe jumping - but don't worry if your garden isn't perfectly flat. With proper preparation and the right approach, you can create a stable, level base for your trampoline. Here's how to transform your uneven ground into a suitable trampoline area.

The Pros of Levelling Your Ground

Long-term Benefits

Taking time to level your ground properly doesn't just benefit your trampoline - it can improve your entire garden's usability. A properly levelled area provides better drainage, creates a more usable space, and ensures safer bouncing conditions.

Improved Safety

A level surface means predictable bouncing patterns and even weight distribution. This creates safer jumping conditions and reduces stress on your trampoline's frame and springs. It also helps your safety net and padding work as intended.

Potential Cons and Considerations

Initial Work Required

Levelling ground takes time and effort. You might need to remove turf, adjust soil levels, and ensure proper drainage. Some situations may require professional help, especially for significant slopes.

Cost Factors

While basic levelling might only need simple tools, larger projects could require machinery hire or professional services. Factor in materials like sub-base aggregate or timber if building a platform.

Choosing the Right Approach

Levelling Kit Solutions

Trampoline levelling kits are a practical solution for minor ground slopes. These adjustable legs or brackets allow you to raise individual legs to compensate for uneven ground. Premium kits offer better stability and rust resistance, making them worth the investment for long-term use. Look for kits with weather-resistant materials and precise adjustment capabilities.

Assessment First

Start by measuring your ground's slope. For gentle slopes, a levelling kit might be sufficient. More significant slopes could require additional ground preparation or platform construction. Consider both the immediate solution and long-term stability. Using a long spirit level or string line can help you measure the exact slope of your ground.

Method Selection

Your options include using levelling kits, basic soil adjustment, building platforms, or installing retaining walls. Choose based on your slope severity, budget, and long-term garden plans. Professional advice can help determine the best combination of solutions. For slopes greater than 5 degrees, consider combining a levelling kit with ground preparation.

Preparing Your Ground

Basic Levelling

Remove grass and topsoil, then redistribute ground material to create a level surface. Use a spirit level to check progress. Add sub-base material if needed for stability. Ensure thorough compaction of each layer. For best results, work in sections and check level frequently as you progress.

Drainage Solutions

Install proper drainage to prevent water pooling under your trampoline. This might include gravel layers or drainage channels. Good water management helps maintain your levelled ground long-term. Consider installing a French drain system for areas with persistent drainage issues. This involves creating a sloped trench filled with gravel and a perforated pipe to direct water away from your trampoline area.

Safety Considerations

When levelling your ground, ensure the area extends at least a metre beyond your trampoline's edge. This safety margin helps prevent issues if jumpers land near the edge of the trampoline. It also provides stable ground for entering and exiting the trampoline.

Maintaining Your Setup

Levelling Kit Maintenance

If using a levelling kit, check the adjustable legs monthly for stability and signs of wear. Ensure all locking mechanisms are secure and working properly. Apply rust protection to metal components, especially in areas where the legs contact the ground. Keep spare parts on hand for quick repairs if needed.

Regular Checks

Monitor your levelled trampoline regularly, checking both the ground condition and levelling kit adjustments. After extreme weather, verify that your trampoline remains level and all kit components are secure. Use a spirit level to check multiple points around the trampoline frame, adjusting as needed.

Seasonal Care

Different seasons bring different challenges. Check levelling kit stability more frequently during wet periods, and readjust if needed. Keep drainage clear and address any erosion promptly. Winter frost can affect ground stability, so additional checks are recommended during thaw periods. Document any adjustments you make to track patterns over time.

Cost Considerations

Equipment Investment

Quality levelling kits typically range from £30-£100 depending on your trampoline size and slope severity. While basic kits are available, investing in a premium solution often proves more economical long-term. Factor in additional costs for ground preparation materials and drainage solutions when budgeting.

Professional Services

If opting for professional ground preparation, expect to pay £200-£500 depending on the work required. While this represents a significant investment, professional preparation can prevent costly issues and ensure proper drainage and stability.

Alternatives to Consider

Platform Construction

For persistent slope issues, a purpose-built platform provides a permanent solution. This can include steps for access and built-in drainage. While more expensive initially, it offers excellent long-term stability.

Location Change

Sometimes another spot in your garden might offer naturally better conditions. Consider whether relocating your trampoline could provide an easier solution than extensive groundwork.
