How to Prepare the Ground for Trampoline


This may be easy or it may take a little work. How much work you have to do will depend on how your yard looks at the moment and whether your trampoline is in-ground (learn about in-ground trampolines safety vs above ground) or above ground. To learn how to prepare your yard for an above-ground trampoline, just continue to read our article.


Steps to Prepare Your Yard

There are a few important steps you need to take in order for your new trampoline to fit right and be safe to use. Here are those steps you need to do to achieve that goal.

#1. Measure your yard — this is important because the trampoline needs to fit inside of your yard’s boundary and have at least 3 to 4 feet to spare all the way around the trampoline. This extra distance is for safety reasons and to make sure your kids can have lots of fun.

#2. Do some yard work – this is the next important step that needs to be done before your new trampoline arrives or is set up. You will need to cut the grass, remove any trees or bushes that will be in the way of the trampoline’s final location. Plus, you will need to remove those trees and bushes to ensure that 3 to 4 feet of safe space is free from them

#3. Check the level – it is not safe to place your trampoline at an angle. This does not add to the fun, it just increases the risks of injury and other dangers. Check your yard to make sure it is level. If not, you may have to do some work and either add material to level the area or take some away. Keeping the ground level adds to the lifespan of the trampoline and keeps it from damage as well.

#4. Cut your grass – you really do not want long grass to continue to grow and reach the trampoline mat. Cut the grass, especially in the spot where the trampoline will sit. This will protect your trampoline and help it last longer. You should be able to cut underneath the trampoline once it is set up. It just might take a little more effort to do so. To improve trampoline safety, you can cut the grass long.

#5. Add a drain – when it rains it will pour and when the water has no place to go, you will be undermining the stability of the trampoline and raise the risk factor when the device is used. Add at least one drain so that the rainwater can move along and be directed to a safer area. You can always remove the grass and add drain rock if you want a low-maintenance trampoline area.

  • The number one reason why grass dies under a trampoline is because of lack of sunlight. Grass and plants need sunlight to grow. Without this, they will die. You will bear with me that underneath the trampoline, there is not enough sunlight.
  • Another reason is the lack of water. Most grasses under trampolines don’t get enough water and they eventually die.
  • There is also a lot of heat underneath. During summer, the jumping mat resisted more heat down to the ground as well as the steel frame passes excessive heat. As a consequence, the grasses die.

If you are wondering what will happen if the grass dies, then are some problems that you may face with dying grass under your trampoline.

The biggest problem will be the legs of the trampoline will shrink which will make the trampoline lopsided and can cause accidents.

What to Put under Trampoline on Concrete

If your backyard is all concrete but you still want to place a trampoline on it for the kids, then you should build the perimeter around the trampoline and install padded rubber mulch and extend the mulch around the trampoline to pad the concrete to prevent injury in case a person falls off the edges or through the springs.

Concrete is a hard surface to fall on. A person falling on a concrete floor from a trampoline jump can be very dangerous.

Even if the trampoline has a net around it, there is still a possibility of a fall, and the concrete floor is a dangerous surface.

Besides it been a dangerous surface to fall, it can also put stress on the frame of the trampoline from the impact over time. This can wear of the frame and cause it to break.

Another issue worth raising is that pea gravel can hide hazards such as broken glass, so be sure not to take any glassware to the area.

This is because of their coloration and size, they are able to hide these objects effectively. So always do regular inspections for these safety concerns.

However, while this may be of concern to you for toddlers, this won’t be the same if you have bigger children.

But the good thing about pea gravel is that it’s inexpensive and relatively attractive, it’s also easy to maintain. That’s why they are common in parks and playgrounds.

It is recommended that you have a protective netting or cage around your trampoline when placing it over gravel because the gravel will cause injuries if anyone falls into it
