5200 |a"Methane entry into basements is a widespread problem for housing structures situated close to either natural or manmade sources of methane. This study was aimed at determining a solution to a methane problem at a group of townhouses situated in Kitchener, Ontario. The source of methane at this site originates from nearby buried refuse. Various remedial solutions including passive venting systems installed at foundation levels and perimeter gas collection systems have proven ineffective. More expensive solutions, such as the removal of onsite refuse, have also been suggested"--Abstract, p. ii.
