Expert: Jonathan Radford - 8/13/2008
Question
I am laying a dry set flagstone walkway at the entrance to my home. What exactly do I place in the joints? The joints are about 1". I have the stones set in a layer of fine gravel/sand. I noticed you answered another question stating that a cement/dry sand mix should be used. But is it a good idea to use a cement/dry mix in the joints on a gravel base when i live in the northeast u.s.a. where we have snowy/icy/cold winters? Won't the walkway begin to heave eventually?
Answer
Hi Erik
A dry sand/cement mix is by far the most versatile of all the pointing techniques. However, if your flags are set on a thin or uneven base, it could create problems. A base of 8-10 inches should allow for any 'heaving' and then a dry mix will work fine.2 inches
The base should be a stabilising base of gravel and smaller particles (dust)and not just gravel. If it has to be just gravel, the pieces should be over 2 inches in diameter to ensure a solid base.
