Which of the following is NOT a component of base cell floor construction?

Surface sealing is not typically considered a component of base cell floor construction in landfills. The primary purpose of the base cell floor is to create an effective barrier that prevents leachate from contaminating groundwater and to manage the collection of leachate that may be produced during waste decomposition.

The other components play critical roles in this system. Geosynthetics and clay liner systems are used to provide a low permeability barrier that helps contain leachate and prevent it from reaching the underlying soil and groundwater. Leachate collection systems are essential for managing the liquid that collects in the landfill, allowing for safe removal and treatment. Protective soils are used as a foundation above the impermeable layers to help support the waste, provide an additional barrier, and help protect the integrity of the underlying liner systems.

Surface sealing, while important in certain context such as capping a completed landfill to prevent infiltration, is not part of the initial base cell floor construction process, which focuses on ensuring effective containment and leachate management from the outset of the landfill’s operation.
