Well planned it looks great after
Inground trampolines are becoming increasingly popular because they are attractively integrated into the garden. The height of the trampoline above the ground is about 20-30 cm, depending on the model, and the safety net is often omitted. In order to have enough ground clearance when jumping, it is necessary to dig a trough under the trampoline. A distinction is made between Flatground and Inground.
Differences in the inground trampoline variants: flush installation or partial burial:
Trampoline flush buried
Effort greater
High cost, material, and time involved. Lateral concrete retaining walls, excavation work and a lot of excavation mean considerable input.
The air that is pushed away during jumping cannot escape on the side. Slightly reduced jumping dynamics are to be expected. The air escapes between the springs, lifting the spring cover, which leads to constant bouncing up and down of the cover. (disturbing noise). Objects or animals falling under the trampoline can be retrieved only conditionally, possibly the trampoline must be dismantled.
Risks:
Small children run onto the trampoline while adults are jumping and can be pecked away.
Jumping from the trampoline directly to the ground (risk of ankle injuries).
Because risks are less perceived, a flush buried trampoline requires special attention!
Trampoline partially buried
easier and cheaper
Manageable effort: much less excavation, no concrete. Can be created yourself.
The frame can be built in any place and then placed over the trough.
The air can escape laterally, so there is no annoying noise.
Small animals can independently crawl back out of the trough. A child can retrieve objects from under the trampoline.
The elevation makes the trampoline more clearly separated.
Here, too, the respect is less than with a normal trampoline and can tempt you to act rashly.
Parental supervision and respectful interaction is essential even with a partially buried trampoline.
If you want to install an Inground trampoline, the following points should be considered:
Das Wichtigste: Zuerst Trampolinrahmen aufstellen, dann erst mit dem Aushub beginnen!
Water drainage: depending on the soil conditions (clay or gravel), it may be necessary to plan for a seepage line / water drainage. During heavy rainfall, water may accumulate in the swale.
Weeds: Against annoying weeds can be laid a fleece in the trough, which is covered with gravel. The trough can also be equipped with seepage concrete.
A safe distance from other objects should be planned around the trampoline. This area should have a cushioning surface such as grass, wood chips or fall protection covering.
Recommendation: When planning the garden, it is advisable to plant trees and bushes so that access to the trampoline is only possible from one side. Otherwise, small children can easily climb onto the trampoline unnoticed when older children are bouncing.
Safety net: A standard safety net cannot be installed on all Inground trampolines. Here we offer custom-made products.
Quality: An Inground trampoline is a long-term affair that will be part of the garden for many years. We recommend installing only high quality trampolines.
Dynamics: Because the trampoline is positioned over a trough, the air has to overcome a little more resistance when escaping, which slightly reduces the dynamics. It is recommended to leave enough space between the ground and the edge cushion so that the air can escape as well as possible. This can also be ensured by means of vent pipes.
How big must be the trough under the trampoline?
Diameter of the trough = [outer diameter of the trampoline] – 60 cm
Lowest point of the trough = 100 cm below the jumping mat
Example of an Inground trampoline with a diameter of 420 cm:
