drain pipes embedded in mat foundations
drain pipes embedded in mat foundations
(OP)
Does anyone have any experience allowing installation of drain lines in mat foundations? We have an 8' deep mat and the mechanical engineer is asking if they can run a 6" or 8" diameter sloping drain line through the mat. I have never before permitted this, but in this case we don't have too many other options. We would have control over where the pipe was to be located and we would locate so that it does not compromise the strength of the mat - and we would add additional reinforcing steel around the drain for crack control. My biggest concern is the problem we would have if the pipe leaked. Perhaps we could require the pipe to be pressure tested before the concrete was poured. We will discuss this with the mechanical engineer. I think the drain line is for floor drains. It is not a sanitary drain that would have a constant flow of water.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
