Tips On How to Burn Brush in the Backyard Safely
1. Use a Long Tarp
The main solution to invest in will be a long tarp that’s water-resistant, robust, and can handle rigorous use such as people sliding on top of it.
If it moves too much, the tarp is going to be utterly useless and not an ideal solution for your setup!
It’s recommended to go for a high-value tarp that is long enough to be placed under the water slide in your backyard. Just having the tarp in place will ensure the water doesn’t spread underneath the water slide and/or do damage to the grass.

2. Rinse the Water Slide Before and After Use
While learning how to protect grass from water slide, you will want to have one eye on how clean the product is.
This means you will want to rinse the top and bottom of the water slide each time. It doesn’t take long but will go a long way in keeping the grass safe.
Make sure you don’t rinse on top of the grass!
This defeats the purpose of what you are doing as the fungus and bacteria will still get into the soil. Instead, you want to make sure to rinse it somewhere else and then place it in the backyard.
This is how you are going to keep it clean. You should also give it a quick rinse after you are done for the day.
3. Don’t Place at the Top of a Slope/Hill
Placing a water slide on top of the hill always seem like a good idea, but it isn’t!
You are going to have water trickling down to one spot in the backyard. What this does is it exposes that part of the backyard to a lot of water, which can result in damaged soil, plants, and/or grass.
You have to be care when learning how to protect grass from water slide.
Having it on an even part of the backyard is recommended. Even a small slope can do quite a bit of damage, if you are using the water slide in the same spot throughout the warmer months.
Make sure to find a flatter side of the backyard and go from there.
This will ensure the water doesn’t dribble down into one spot creating large puddles that aren’t going to dry easily.

4. Switch Spots Regularly
You will have to make sure to switch spots regularly when setting up the water slide in your backyard.
This means not always having it positioned in one part of the backyard or at one angle. Instead, you should look to move it around.
In fact, you shouldn’t have it in the same spot again for months at a time. It just won’t keep the grass safe.
Final Thoughts
This is how to protect grass from water slide.
Using a water slide is loads of fun and highly recommended during the warmer months, but it is your responsibility to have a good-quality tarp underneath.
The tarp should be water-resistant, easy to set up, and robust.
This is a must and it is the only way the grass is going to stay safe for years to come!
