Plastic under pool/rocks.

I'm planning on using Indian Creek Gravel in the back yard to make an "oasis" around and under the pool. It's larger than pea gravel and has a nice smooth texture. The plan is to lay about 5 tons of it in the back yards about 2-3" thick.

I want to use 1" insulation board over top of the gravel for "smoothness", tarp, then pool. The AGP's legs will be on 12x12" concrete pavers set in/on the stone and leveled.

The goal was to relieve the requirement to mow around the pool and between the pool and back deck. I got some free 7+ mil thick heat shrink wrap (think the stuff they use to wrap a boat) that I was going to lay down over the grass, under the rock. This is two fold. One, it keeps the rock separate from the soil so if we plan to remove it it's easier and also stops weed growth so I can limit my weed killer spraying. My only worry now is that water will have no where to go generally as the plastic isn't permeable so I was thinking of poking small holes in it here and there to let water drain.

Anyone done anything like this? Will this defeat the purpose of weed barrier?

Weeds and grass grow through plastic all the time, and every time, so in my opinion spray is the best week barrier.

Poking holes in the plastic is a good idea and is what I would do.

Sounds good. I have some laid out in the area and noticed puddling when it rained on it. Thought about putting some drains through it as well and pipe it out.
