we just had a 10x10 4 in thick with 2 wire mesh overlapping in the center mainly, for 500.00. We live in So.Cal. We put it over our newly filled in pool. I hated it. finally it is gone. got our spa today. it is great . wish i COULD STAY IN L0NGER. Ours will surely fail before everyone elses because eventually the dirt will compact no matter how big of a CAT they drove over it. Am I worried, nope cause the pool is gone and the spa is here.
