Thank you so much for taking to time to answer my questions. I get so many different opinions and have to sort out the right way. Sadly, I am going to have to let this installer go and take the time to hire another. He is not being honest with his billing. Such outlandish ways to pad the bill, and him leaning on his shovel for half the time he is here. I shouldn't have gone with someone who charges and hourly rate.
How many inches of 57 stone are necessary? 3", 4"? Then the crusher dust to the level of the pavers? One more question as stupid as it sounds: It's a 24' round pool, should the pavers be placed 24' across from one another exactly? There are 16 of them and it is easy to spray paint a 24' circle, then set the pavers just outside of that circle. Is that the usual paver placement?
