Radon Gas (as well as other potentially harmful
soil gases) flows upward, out of the earth following the
path of least resistance.
When this radioactive gas "hits" the EmeSeal
floor liner, it begins to build up pressure. Instead of
simply trying to "seal out" this pressurized gas
(something very difficult, that others try to do) the EmeSeal
Systems' radon gas dispersing drain fabric allows the gas
to flow beneath the floor liner to the radon gas ventilation
pipe, which surrounds the perimeter of the crawlspace. Then
the gas is passively vented to the outside through the radon
gas ventilation pipe, relieving the
built-up pressure beneath the floor liner.
This ventilation system combined with our exclusive
moldable roll adhesive and permanent seaming tape makes
the task of "sealing out" harmful soil gases a
reality.
