I will be building a backyard playground this spring. I have been searching online and most of what I find is "free plans"
I was planning on using pea gravel as a base, but I want to make sure I have proper drainage.
I was planning on leveling and digging down some with my tractor. Installing all of the poles Putting down a heavy layer of plastic Timbers around the edges to contain the gravel. Then filling with pea gravel.
But I think I need to add something for drainage.
