Leveling Help

[Scruffy01]

16' 48" round pool. I have an area covered in sidewalk blocks that is not perfectly level so I am thinking of building an octagonal frame with two x four's to create a level area and fill it with sand. Maybe even capping it with 3/4" plywood to give a complete level area???? Does anyone have any thoughts to this? Any help is appreciated. Cheers

Building up can cause future problems. The wood moving and sand being washed out You would be better off lifting the blocks excavate and levelling it with sand

Due to the winter this will only be up for about 3 months and then taken completely down. I have plans to use a heavy poly to stop the wash out. The area is a dog run and I don't want to remove the blocks as we will be getting another dog at some point. Appreciate your response. Cheers
