Landfill Temporary Cap, Italy

Project Details

There comes a time in the life of any landfill when it cannot accept additional material. When this occurs, it is necessary to construct a cover above the waste. Sometimes due to financial/operational reasons the construction of the final cover is delayed. In this situation the construction of a temporary landfill cap should be considered.

The benefits of temporarily capping the slopes during the postponement period may include:

• Preventing rainwater from becoming leachate (i.e., leachate reduction).
• Eliminating routine mowing.
• Eliminating maintenance of storm water swales on slope.
• Eliminating soil erosion during storm events.
• Controlling odors from the temporarily capped area.

The geomembrane to use in the temporary cap will be exposed to many environmental factors: ultraviolet radiation, extreme temperatures, impact load (wind), down-slope creep… For that reasons the geomembrane to use in this type of application need excellent weathering/UV resistant and mechanical properties.

ATARFIL HD geomembranes are manufactured from best in class High Density Polyethylene (HDPE) resins coupled with a specific antioxidant package by the most advanced in-house flat-die technology. This result in a quality and uniform product with excellent weathering/UV resistance and long-term performance. The cost/benefit ratio analysis appoint HDPE geomembranes as one of the best options for a temporary cap.
