PLASTIC MEMBRANE FOR S.M.D. SYSTEMS


The captioned photos above are of the 6-mil cross-laminated reinforced plastic membrane exclusively utilized by Timmit Radon Systems for covering crawlspace floors in sub-membrane depressurization (S.M.D.) system applications.  The membrane, which is also available with a fire-retardant option, is purchased commercially which makes its use exclusive to Timmit Radon Systems.  The membrane is anchored to the foundation wall through the use of pressure treated 1" x 4" dimensional lumber and the top edge is normally sealed with caulk but expanding foam sealants may be necessary when the foundation walls have irregular surfaces.  All joints are overlapped at least twelve inches and are sealed with duct tape which ensures the applied joint sealant cures properly. Once the extremely durable membrane is installed, the crawlspace can still be used for storage purposes.
