i have several patches of dirt in my mostly concrete backyard that i would like to cover with paver stone so that weeds don't grow out of it. i am not much of a landscaper and prefer being surrounded with surfaces from which unwanted plants cannot grow.
so i was wondering what i should do to prepare the ground for paver stones. can i just set them over top of dirt or should i perhaps put some weed block first and then a later of gravel on top and then paver stones? basically, what is the most effective sequence of layers?
I'm no expert but I have put down pavers on bare dirt. Weeds and grass grew through the joints, and since I live in an area that freezes in the winter, I got a little frost heave. A base layer of anything that provides good drainage like gravel and maybe sand should reduce frost heave.
My thought is that after laying down the pavers, regardless of any weed barrier you'll need to throw down sand and vibrate it into the joints for weed control. Otherwise wind-blown dust gets into the joints and becomes soil that lets the weeds get started.
