Question of the Day - #106 2 rules for 1 application

1303.2402, subpart 2, requires soil gas retarders to be lapped 12 inches. R506.2.3 requires the vapor retarder under the slab, which will also act as the soil gas retarder, be lapped six inches. Now this isn’t anything new. The same conflicting conditions exist under the current code. But since it appears that the code gods were aware of this conflict and there was an opportunity available, why wasn’t there an effort made to coordinated the rules? Yah, yah, yah, I know about the rule that says the most restrictive applies but why do we need to play this game of “gotcha” with the construction industry. It makes us look like, well… bureaucrats!
