A method and apparatus is used for covering the exposed workface of a landfill with a film. The apparatus includes a compactor rotatably mounted on a frame which is hitched to a tractor. A film, spray and ballast deployer is mounted on the end of the frame for spraying the landfill, deploying the film onto the landfill, and deploying the ballast onto the film. The compactor includes a roller which compacts the waste prior to spraying the landfill and deploying the film and serves as a wheel for the frame. Hydraulics are provided to raise and lower the deployer. In operation, the assembly is pulled by the tractor causing the compactor to compact the waste just prior to the deployer laying the film on the workface and the ballast being deposited onto the film. Additionally, the apparatus is capable of casing the overlapping layers of laid film to adhere to the ballast in between thereby forming a seal between the adjoining layers.
