Paver Patio Base Grading
I'm building a 17'x23' paver patio and have finished the 6" compacted crushed stone base. My question relates to flatness of this layer. While I maintain an overall pitch away from the house, does the crushed stone base need to be perfectly flat before the slag sand/stone dust goes down? In other words, can one area have 1.5" of stone dust, while another may only have 3/4"? The overall slag sand layer will be perfectly flat and pitched, but does it need to be a uniform thickness throughout?
I ask because getting the crushed stone base perfectly flat has been a chore, and I am still left with small valleys and hills. Albeit the variance is probably 1/2" on average, but I want to ensure this won't affect the final [seasoned] level of the patio.
Thanks for the guidance with this!
