Wondering if anyone can help me here:

I have a customer installing H20 rated (roadcrossing) cable trench and he wants to know what the "derating factor" (out of the Code) is on the HDPC (High Density Polymer Concrete) cable trench....One manufacturer of this material is a co called Trenwa.

Any help would be appreciated
