I recently purchased a skid of what appears to be manufactured slate. I plan on digging a new walkway on my lawn and laying this stone and need some info on doin' it right! I live in Pa and have some pretty interesting weather which I believe is something to be taken into consideration. If its a good idea to lay this stuff in/on a bed of cement, could you offer some info on how to do it including what I should fill the gaps in between with.

The Tile Council has a spec for this which involves pouring a cement sidewalk, sloping it with mud, laying a membrane on top of that (to drain moisture), installing a TROBA drainage mat, and then floating a mud bed setting bed, also sloped.

This keeps moisture out of the substrate and setting bed and prevents frost heaves.

Check the moisture absorbtion rate on your tile. It needs to be very low, so it doesn't capture water, and upon freezing heave.
