RAM Vent™ is a lightweight entangled geomatrix manufactured for use in an active radon mitigation system. RAM Vent™ is manufactured with a heat bonded filter fabric on one or two sides allowing air to flow freely based on our 95% open entangled design.
Additional Information
Unroll RAM Vent™ along the perimeter of the footings on top of the soil.
Lay a cross piece of RAM Vent™ through the center parallel to the longest wall every 15 to 20 feet. Then, overlay the subfloor with a vapor barrier extending up the wall.
Cut a 3” (8cm) hole in the vapor barrier near the most appropriate corner. Next, glue a 4” (10cm) flanged riser pipe with a detachable cap to the vapor barrier and sitting on top of RAM Vent™ (The pipe stub should be long enough to extend above the top of where the slab is poured). Then, pour the slab. Finally, extend the vent pipe through the roof.
Additional Instruction— Make sure to seal any cracks/ seams etc. on top of the concrete with a sealant, such as silicone.
