Permanent Landfill Safety: Geomembrane Cover-Up Solutions
Waste management is crucial for the Environmental and public health protection. RNP (Non-Hazardous Waste) landfills are among the most common methods for the disposal of municipal solid waste. However, their management requires specific precautions to ensure safety and sustainability.
In this article, we present a success story that leverages the Reinforced geomembrane Cover Up for the permanent securing of an RNP landfill.
Setting Up and Closing the Deposit Cell
The creation of an RNP landfill begins with construction of a handover cell where we collect and separate waste. Once the planned fill level has been reached, we close the cell and start the permanent safety phase. This phase consists of protecting the landfill from erosion and the infiltration of water and gas.
The standard final cover includes several layers: a mineral layer, a compacted clay layer, a drainage layer, and a vegetation layer.
Preventing Leachate with Geomembranes
Rainwater infiltration can produce leachate, a highly polluting liquid that can damage the surrounding environment. To prevent this problem, we integrate a reinforced geomembrane in the final coverage.
Permanent Safety and Cover-Up Technology
The landfill remediation required a series of interventions:
Biogas capture.
Clay compaction.
Installation of the reinforced geomembrane.
Surface water drainage.
Thanks to the reinforced Cover Up geomembrane, We have minimised on-site welding., Furthermore, the lightness of the product allows for quick installation, reducing exposure times and the overall costs of the intervention.
The Cover Up series geomembranes they solve environmental problems while ensuring economic sustainability. Their high mechanical strength, flexibility and adaptability make them a very effective for the permanent securing of RNP landfills.
Technical Details of Coverage and Benefits
For the final cover, we requested:
A compacted mineral layer.
A compacted clay barrier.
A drainage system for biogas and water.
A final green restoration.
To minimise infiltration, we suggested the integration of Reinforced geomembrane Cover Up, having proven to be an effective barrier (20,000,000 square metres already installed).
Following active landfilling, we implemented permanent capping through landfill body reshaping, biogas collection, clay compaction, the installation of a reinforced geomembrane, and surface water drainage.
Finally, We have started the environmental remediation of the site, restoring the topsoil to protect the barriers and facilitate seeding against erosion.
Essential Advantages of Cover-Up Geomembranes
We chose the reinforced Cover Up geomembrane because protects clay soil and ensures a double waterproofing barrier thanks to:
High tensile strength It takes the load of the topsoil and the settlement phenomena of the waste.
Flexibility and adaptability: It supports the drainage layer and topsoil, preventing slippage.
Reduced welding: We will minimise site welding by carrying it out in the workshop.
Cost savings The executing company can quickly install the reinforced geomembrane.
The Cover Up geomembrane, functional and convenient, they are designed with high mechanical strength values. An internal HDPE fabric acts as a reinforcing armour, and the hot lamination with a triple layer of LDPE ensures the impermeable barrier. The work was completed with low investment costs and reduced exposure times.
