Vent Details

 

 

 

Flap vents are installed at the crest of the slope to allow for venting of air or gas trapped under the liner during the covering operation. Once the liner has been completely covered, these vents serve no further purpose.

 

Landfill covers require venting to relieve gas pressure under the liner.  This detail shows a typical gas vent utilizing perforated and solid PVC pipe.
