Hi! I'm Mark Sullivan for Expert Village and today, I am going to show you how to set concrete paver's. The next step is to put some black plastic on the ground before we set down our paver's. We have this sheet of used black plastic that looks like it has been used for some spray paint projects and then we have our pit, barbecue pit here. So I think that what we are going to do is cut a whole in the black plastic and set it over our pit. I am going to measure from here to about here. We are just going to cut a big circle with a razor blade and we will fit this right over the barbecue pit.
