Hybrid Landfill Gas Mitigation System Implementation
OVERVIEW
The site is located in North Miami, Florida and is the site of a former landfill. Langan designed a hybrid landfill gas (LFG) mitigation system to control the potential intrusion of landfill gas (primarily methane) into a recreational building complex proposed to be built atop the former landfill.
The LFG mitigation system consisted of a vapor barrier and hybrid LFG venting system installed under the extents of the building complex floor slab. The innovative hybrid system design allows for both passive and active, if needed, venting of LFG generated below the slab of the building complex.
