If you want to level the trampoline completely, the core logic is actually a few steps: first take a level ruler to find out where it is low, and then we have two ways to go-either dig out the soil on the high leg to make a groove, or put a stackable leveling block on the low leg . However, no matter which road you choose, you have to pad the foundation with concrete or floor tiles and then apply a professional ground anchor fixing kit.

The following is a detailed explanation of two specific operation schemes:

Why Does A Trampoline Have To Be Leveled?

Many people feel that the trampoline is a little crooked just look uncomfortable, this is a big mistake. This is first and foremost a security issue. If there is a slope in the backyard, the rebound force when jumping will become very strange, easy to throw people low, directly increasing the risk of falling out of the net or hitting the spring.

Moreover, from the point of view of equipment maintenance, the uneven frame force is extremely uneven. Those long-term uneven stress on the shelf, the long time legs will bend, the joint is also easy to break. The simple summary is: either use leveling blocks (suitable for small slopes, save trouble) or dig trenches (suitable for large slopes, secure).

Method 1: Use Trampoline Leveling Block (Labor Saving Scheme, Suitable For Small Slope)

If you, like me, don’t want to sweat and dig in the hot weather, and the slope is not too exaggerated, then leveling blocks are definitely the first choice. The principle of this trick is very simple: pad the short leg high and accommodate the long leg.

Positioning And Assessment:

First move the trampoline to the final position you determine. Take a carpentry level on the frame and see which side is lower. Don’t be lazy in this step, you need to find out exactly how much height to add to the “low legs” in order to make the bed level completely.

Select The Right Material:

I have two suggestions here.

Special Leveling Block: Special products like “Level Dry Blocks” are preferred. They are designed with interlocking structure, good weather resistance, but also load-bearing.

Hardcore DIY Materials: If you don’t want to buy special, use thick paving stones (pavers) or concrete blocks. But be sure to choose a large enough and strong load-bearing, after all, the trampoline jump that the impact is not a joke.

Placement And Stacking:

Lift your lower leg up and tuck in your chosen pad.

Tiny Slope: One brick may be enough.

Large Slope: Need to stack up. If it is a special block, lock them with a buckle. If bricks are used, be sure to put them neatly to ensure that they will not shake. Your goal is to keep fine-tuning until the bubble of the level is completely centered.

Fixed:

After the pad is good, one side is high and the other is low, and the shelf is actually relatively “hanging.” In order to prevent the children from jumping and sliding their legs, they must add ground anchors (I will elaborate on the safety part later).

This video demonstrates how to level a trampoline using simple DIY methods:

Method 2: Digging Trench (Suitable For Large Slope, More Stable)

If the slope of the yard is visible to the naked eye, it will make the trampoline’s center of gravity too high and unstable if the low leg is forced to be high. At this time, it is more professional to honestly dig out the soil on the other side of the height and let the “high legs” come down.

Mark And Excavate The High Side:

First, find out which legs are on the high ground and move the trampoline temporarily to make room. The purpose of digging shallow ditches at the corresponding positions of these legs is to remove excess soil and let the high legs “sit” in the pit to make do with the height of the low legs.

Return And Adjustment:

Move the trampoline back and let the legs fall into the pit. On the level again. If it is still uneven, then we have to continue to dig down. Sometimes it is necessary to dig a little under the lower legs to ensure that all legs are firmly “embedded” in the ground, rather than floating on the soft turf.

Compaction And Support (Key Steps):

Never stick the metal leg directly into the soft soil that has just been dug loose!

Compaction Of Soil: The soil at the bottom of the ditch must be compacted with force.

Add A Base: In order to prevent the legs from getting stuck in the mud for a long time (then the trampoline is crooked again), I strongly suggest to pad a paving stone or anticorrosive wood at the bottom of the ditch as the base.

Hardcore Recommendations For Stability And Safety

Whether you choose to raise the height or dig the hole, the last few steps are mandatory and not negotiable, unless you want to rework in two months.

Build A Solid Foundation: Trampoline legs are like high heels, which can easily sink into the soil after rain or under long-term pressure. If you dig a trench, you must put bricks in the trench; if you use a leveling block, the ground must be compacted under the block.

Install A Ground Anchor (Anchors): This is a life-saving step. A ground anchor (usually something that spirals into the earth) must be fitted with a strap to lock the frame to the ground. It can not only prevent the trampoline from shifting from the leveling block, but more importantly, on windy days, it can prevent your trampoline from turning into a kite and flying to the neighbor’s house-I have seen this kind of thing more often.

Regular Review: The soil will settle and the cushion will shift. Form a good habit and take a level ruler to measure it every other time. Equipment maintenance is not done once and for all.
