Once the layers of clay, geotextile, plastic, soil and gravel have been laid (the combination of those is dependent on the site owners’ preferences and agreements made upon application), next the cells are formulated. Cells, in landfill terms, are the name of the sections where waste can be tipped. When one cell is full another is usually being prepared until the site is complete. After every occasion or waste disposal a compactor drives over the waste in order to create a level surface and use the space effectively. At the end of each day a layer of soil or matting is spread over the top to prevent odours and prepare the ground for additional levels or simply to finish that cell. If it’s full a plastic cap is also placed over the top before work begins to restore the land.
