IT Employment
I'm replacing cable between two of my buildings and we noticed water damage even though it was located in coduit. I'd like to make sure we put in cable that will resist the water if it gets in again. I can't seem to find any cable vendors that have this type of cable. Anyone have any suggestions?
TIA,

Check with a local electrical supply house.
They should have or be able to get either CAT5 aerial or burial rated cable for you.
Either should have sufficient water resistance for your needs.
You might want to discuss with an electrician how you can reduce condensation and seepage in the conduit.

Depending on distance and connection speed;
250ft Tbase10/100 should be able to use standard direct burial cable, copper shielded and rated for under-water use. 22ga icky-pic (soft-gel filled to seal against water) should do. Could use DS1 (T1) port and a pair of TSU's/CSU's to compensate for distance.
Sounds like either there is a hole in the conduit or neither end used sealant on the end of the conduit (approx. $15 for a 5lb block) Air conditioning will cause water (condensation).
I am thinking about a) drilling holes in the conduit, b) tilt one side of the conduit so the water could go to the other side, c) use a wireless radio 2.4 GHZ, 5.8GhZ or a fiber optic connection.

With the high cost of the Water Resistant CAT5, it is almost the same expense to go fiber optic.
You are never going to keep water out of underground conduit unless you have a system to pressurize it with dry nitrogen like the telephone company does.
Forget it, too much trouble.
Just think of the conduit as mechanical protection to prevent the cable from being crushed, and to make changes easier.
