Drain pipes/radon – GreenBuildingAdvisor

My contractor uses form-a-drain – thoughts on this in a high radon zone? is it better to have a separate radon pipe? I’m not sure how I feel about form-a-drain in general but it is what he prefers to use.

I’d prefer a designed footing drain system but can’t seem to find a specialist who does it where I am. Our architects are in Canada and we are building in Midwest.  They aren’t familiar with radon. Who would typically design footing drains/radon system?
