RE:
>The problem is that once you draw air from the under-slab plenum, the plenum is under negative pressure, and soil gasses, such as radon, water vapor, biological
by-products, etc., can be drawn into the plenum through cracks, and then
blown into the living space.
Blowing into the plenum pressurizes it and would seem to eliminate those dreadful problems.
