Pool Krete on Top of Gravel in Pool Bottom
I am building vinyl liner inground pool. PB was doing the pool krete on the bottom today. In the shallow end I noticed there was an inch or 2 of gravel. He was putting the pool krete over the gravel. Everything I read said bottom should be free of rocks and lumps before putting it down. (He is gone now, raining of course)Is this right?
Is he doing something he shouldnt? Before I ask I would like to know my facts, since I have been asking him alot lately.
