I use 1/4" hardibacker. It's the material used behind you shower tiles.
You can find it at Home Depot stores. It's easy to cut to size... just score
and snap off.
I use it on indoor/outdoor mosaics and they have held up really well. I
haven't used anything underneath.... it doesn't seem necessary. If the 1/4"
seems too thin it comes 1/2" also.

My tables are 24" x 32 and seem fine, not so big a span. I think the
original
person's question referred to a four foot span which is why I suggested a
support
to keep the durocrete from flexing.. Plywood underneath would work ..just
need a
thicker lip.
I wouldn't use only plywood for outdoors though. I guess you could, but I
think of
the durocrete is more natural to use with tile.
