What kind of network cable to run underground?

I want to network 2 buildings about 15m apart with CAT6 cable through an underground 100mm PVC conduit. What could go wrong?

We will upgrade our telephone system soon. This will entail connecting the two buildings with said conduit at a depth of 1m. The smaller building is currently connected to our network via wireless bridge. This presents the perfect opportunity to connect the network with a physical cable and eliminate some stability problems and increase transfer speed. I plan on using CAT6 because of the extra shielding and outer jacket that seems to be a bit thicker than usual. Will this suffice? If it is laying safely within the dry conduit, do I need to use a special kind of cable? What if condensation builds up in the pipe after a while? I know there are some cables rated for underground use but I am unsure if this is only for cable being directly buried in the dirt a few feet below the surface or if this includes conduit runs as well. Also, if there are telephone cables running alongside the CAT6, will it still be safe from interference?
We did consider using fiber but it was a bit cost prohibitive and we need to have a connection up and running sooner than we can get technicians out here to do it. Maybe we'll do it later. The conduit will be laid with pull wires so we can pull additional cable in the future if we need to.
