A twenty-mil Drago soil gas barrier or engineer-approved alternative installs over a sub-base and extends up the face of a concrete column. A twelve-ounce non-woven geotextile layer sits beneath the gas barrier. Drago seal tape and a Stego termination bar (batten bar) secure the barrier to the column face. Drago tack tape applies at the base of the column to seal the transition between the barrier and the concrete surface.
