Typical final cover systems eventually become damaged over time, and may develop problems related to slope veneer failure. Normal landfill gas collection and control systems, commonly referred to as GCCSs, comprise several large mechanical components and are designed to assist with odor and emissions control, as well as landfill gas migration control, to minimize unexpected explosions. In some cases, to address and solve additional leachate production problems, a geosynthetic leachate collection and removal system (LCRS) can be put in place.
Excessive landfill gas (LFG) pressure below the structured geomembrane barrier layers can also become problematic and will need to be swiftly addressed. To remedy this, sub-barrier layer LFG collection systems can be installed beneath the geomembrane to increase strength and stability in the site layout. LFG control systems are specifically designed to accommodate the varied, inconsistent nature of various different types of landfills, such as C&D (Construction and Demolition) landfills and Municipal Solid Waste (MSW) landfills.
When it comes to landfill gas control solutions, many different landfill liners, covers and/or capping systems are utilized together depending on the amount of waste present, as well as the specific contents of the site. Using our years of experience in the industry, the skilled team at Watershed Geo specializes in the design and construction of landfill waste and gas odor control products that guarantee that your landfill site is as safe and sanitary as possible.
Our landfill covers, liners and capping systems reduce leachate, storm water runoff and methane gas emissions. If you require dependable, cost-effective landfill gas collection and control products, ClosureTurf® and VersaCap® can help!
