What are the pros and cons of
having a slab with set in mortar bricks and not. Sand set does seem to cost
less, but you do not want to make the wrong decision on that basis.

Depends how long you plan on living there,bricks set in mortar last alot
longer then in sand.you can even have cement colored and poured to look like
bricks but its really one slab .
