Tilting trampolines can cause the jumper to fall off their side. A perfectly level, flat lawn is the best surface for erecting a trampoline. Unfortunately, many lawns do not meet this requirement. You can rectify a lawn that slopes less then 2.5 cm (1 in) for every 17.5cm (7in) horizontal distance by digging trenches to the top-slope legs. While this can require some supervision, it is worth the effort to ensure the best trampoline setup.
The trampoline should be placed in an area where it will be used. Place a plank in the middle of your trampoline so it runs in the same direction as the slope.
Place the carpenter’s level on top of the trampoline. Lift the plank so that the level of the carpenter shows the level of the plank (the bubble lies in the middle of these lines). Measure the distance from the trampoline’s top to the edge of your board using the ruler. You will need to adjust this total slope.

- The ruler can be used to determine the distance from the trampoline’s top to the edge of your board.
Divide the trampoline’s overall diameter by its slope. If this is higher than 17.5cm (7inches), then the trampoline area needs to be adjusted. You should relocate the trampoline.
You will need to move the trampoline from the path and make a trench underneath the place where you’ll be placing the trampoline’s uphill legs. You should measure the slope and dig the trench to equal its depth. To ensure that the trench is level, use the carpenter’s level.
Divide the trampoline’s diameter by the slope total.
- You will need to move the trampoline from the path and make a trench underneath the place where you’ll be placing the trampoline’s uphill legs.
Place the trampoline in its original place, keeping the uphill legs at the trench. Due to the fact that the trampoline has side legs higher than its uphill and lower legs, the trampoline may become unstable. Make trenches beneath the side legs to ensure that the uphill- and downhill legs remain firmly in place.
Make sure the trampoline has been leveled in all directions. If necessary, adjust the trenches.
You may have to put 2.5 cm (1 in) of gravel into the trenches, if your trampoline is to be used on sandy soil. For the whole trampoline base, you can dig a level round hole approximately 7.5cm (3 inches). Although this makes mounting the trampoline much easier, it also reduces the chance of it falling. However, it takes a lot more digging. As you dig trenches, take your time and ensure that the soil is level. It is easier to dig a trench deeper than it is to fill one with too much soil.
The risk of injury is greatly increased by a trampoline that is unstable or sloping. Be sure to follow all manufacturer instructions. With continued heavy use, trampolines may settle. Check the trampoline’s level regularly and rectify any slopes. Trenching is not safe for certain types of trampoline legs. Refer to the manufacturer’s instructions.
