Above Ground Pool On Artificial Grass

Artificial grass generally performs better compared to natural grass around a swimming pool. Turfs can withstand any pool chemical which will quickly kill the natural grass. Moreover, if you properly install the turf it will also provide a drainage system, that is sometimes better compared to the drainage provided by natural grass.

Above Ground Pool On Natural Grass

Placing an above-ground pool on natural grass might not be the best idea out there. There are many reasons that explain why natural grass and above-ground pool both do not mix well. If you intended to do so, remember the pool will kill the grass. Even if you keep the pool for a short length of time, the grass underneath the pool will die.

It would be good for you to take the pool down over winter, so the grass will come back over time, especially with re-seeding. There is a chance that natural grass will look good again as the weather will be warming up over time, and you will be eager to bring the pool out again, and the endless cycle continues. Apart from this, it is hard to maintain the natural grass around the pool. Since natural lawn grass gets muddy when wet, mud slipping into the house can be a safety issue. They can be quite slippery.

Another thing is, it is also important to check the place where you place the pool. Even a gentle slope causing discrepancy can shorten the lifespan of your pool and cause the lower wall to fall. If you are planning to install an artificial grass lawn, we suggest you rely on your turf installer.
