124 Figure 15 - Filling and spreading soil over the geocells. In sections where vehicle traffic was necessary on the slopes, additional reinforcement was considered through the application of a second layer of geogrid, so that the geosynthetic coating could support the additional loads without compromising the stability of the cover. Once the soil filling was completed, the vegetation planting process began, as specified in the project, where the thickness of the soil layer allowed for vegetative development and avoided interference with the drainage and waterproofing system. Figure 16 - Finalized coverage, with soil layer implementation and early vegetation development and vegetation cover. 4. CASE HISTORY Nº3 - ASH DUMP CLOSURE COVER, TARAPACÁ, IQUIQUE, I REGIÓN, CHILE
