This is an in-between event where we dug in some ventilation ducts to transfer fresh air to the rooms that need it.

Running the Radon Tubes thru the living room… 
Here is where the vent ducts pass thru the mechanical room wall. 
Registers are formed with insulation and then the concrete floor is poured around them. Later, we can dig out the insulation to access the duct. 
I used my Laser level to set the registers to match the floor hight. 
Ducts crossing the hall way to get into the bedrooms… 
This duct section is passing thru this room… We will add a register opening. 
Vent duct with a register knockout ready… 
They make lots of fittings and connections for these tubes, but they don’t make an “end cap”. I made my own with a coupling and a circle of rigid insulation. 
This is the last register on the duct… So it is the thinnest.
