I had an install drain tile system installed (approx. 80ft). This is where the floor along the footing is busted up, drain tile and weep tubes are added to the cinder block cores, and then re-concreted. My question arises because a 1/2" gap is left along the perimeter to allow any condensate to drain into the system. I plan on finishing these perimeter walls with an insulated 2 x 4 wall. I have noticed sow bugs crawling out of this gap. If I finish the wall, won't these bugs cause problems? Does this gap increase the chances of Radon problems? Should I seal this gap? I was planning to add a bubble wrap type of vapor barrier into the gap, and go up an additional 16" on the block wall, and install vapor barrier the "warm side" of the new insulated wall.

was going to do some basement remodeling but from floor to ceiling is only about 5'6" i would like to dig upthe concrete and remove about 1'6" of the dirt and repour the floor my ? is will there be any problem doing so would there be a problem with the footing or anything thanks in advance for the advice
