Our Crawlspace Project
Crawlspace ventilation lowers indoor radon levels by reducing the structure's suction on the soil and by diluting the radon beneath the building.  Sub membrane depressurization involves covering the earth floor with heavy plastic sheets.  A vent pipe and fan are used to draw the radon from under the sheets and vent it to the outdoors.
