Can You Put a Normal Trampoline In The Ground

Trampolines are beloved backyard staples, but they’re often large, visually dominant, and potentially hazardous if not properly secured. One increasingly popular idea among homeowners is to place trampolines in the ground, creating a flush, safer play area. But can you put a normal trampoline in the ground?

The answer is yes—but with some serious qualifications. While it’s possible to install a standard above-ground trampoline below grade, doing so requires significant planning, customization, and attention to safety. It’s not as simple as digging a hole and dropping in the frame. Whether you’re looking to create a sleek, low-profile trampoline or want to reduce fall risks, here’s what you need to know.

Understanding In-Ground vs. Above-Ground Trampolines

Above-ground trampolines are designed with elevated frames that rely on legs and anchoring systems. In-ground trampolines, by contrast, are engineered specifically for sub-surface installation. They typically include special retaining walls, ventilation systems, and corrosion-resistant parts.

Attempting to install a normal (above-ground) trampoline in the ground means adapting a product not meant for that purpose. Without modifications, issues like poor bounce, trapped moisture, and rust can quickly arise.

Excavation and Site Preparation

To place a normal trampoline in the ground, the first step is excavation. The hole must be deep enough to accommodate the frame and jumping mat movement—usually around 3 feet. But it’s not just about depth; the hole should have sloped sides and a slightly wider base to allow air to move and water to drain.

Poorly prepared pits can result in muddy buildup, standing water, or air compression that hampers bounce performance. A French drain system or gravel base is often necessary. According to Ready.gov’s outdoor safety guidance, proper drainage and air circulation are two of the most important features in any in-ground setup.

Frame and Material Modifications

Normal trampolines are not designed to resist underground conditions. Their frames may corrode faster due to increased exposure to moisture and soil. Coating the frame with rust-resistant paint or galvanizing it can slow degradation.

Additionally, placing a trampoline in the ground can restrict airflow, which is necessary for proper bounce. Many in-ground trampoline kits come with ventilation panels to solve this. If you’re adapting a regular trampoline, you’ll need to allow for airflow using perforated trench walls or installing vent tubes.

Safety Considerations

One of the key motivations for placing a trampoline in the ground is reducing fall risks. Without a raised edge, children are less likely to suffer injuries from falling off. But this doesn’t eliminate all hazards.

Ground-level trampolines can become hard to see, especially if surrounded by grass or landscaping. Installing a safety border or colored edge around the trampoline helps with visibility. Additionally, ensure the trampoline pit is covered when not in use to prevent accidents, particularly with small children or pets.

Impact on Bounce Performance

Standard trampolines rely on open air beneath them to absorb force and rebound properly. Placing them in a confined pit without ventilation can limit their bounce. This issue can frustrate users and increase stress on the frame and springs.

To combat this, ensure the pit includes adequate space under the jumping mat and that air can move freely. This is why many in-ground trampolines feature built-in airflow channels. Without this feature, a normal trampoline’s bounce may feel sluggish or uneven.

Maintenance and Long-Term Use

Once installed, an in-ground trampoline made from a standard model requires regular maintenance. Check for water pooling after rainfall, inspect for corrosion or mold buildup, and ensure the frame stays level as soil settles.

Weed control is another concern. Use landscaping fabric and gravel or stone around the perimeter to reduce unwanted growth. Keep the area clean and free from debris, which can build up faster in a pit than on a raised surface.

Covering the trampoline when not in use also protects it from the elements and keeps pests out. In colder climates, consider winterizing it by removing the mat or covering the entire pit with a weatherproof tarp.

Professional Installation vs. DIY

Installing an above-ground trampoline in the ground is not typically recommended as a DIY project unless you’re experienced in excavation, drainage, and structural work. A poorly executed job can lead to costly damage or safety hazards.

Professionals who specialize in in-ground trampoline installations understand the importance of airflow, drainage, and frame stabilization. While it adds to the upfront cost, hiring a pro can save significant money and stress down the line.

When It’s Better to Use a Purpose-Built In-Ground Trampoline

If you’re set on the idea of a ground-level trampoline, it’s worth considering a model specifically designed for that purpose. In-ground trampolines come equipped with features to address all the challenges discussed above. Brands that specialize in these setups include systems for drainage, airflow, rust protection, and ease of access.

While you can technically adapt a normal trampoline, using a purpose-built model reduces the need for extensive modifications and boosts performance and safety.
