1044 Figure 9 –Type C4 cover. 2.5 Coverage Installation Procedure The geosynthetics were installed in accordance with coverage types C1 and C3. Figure 10 – Installation of geosynthetics (left) and completed project (right). Preliminary work was carried out at the waste dump, such as removing surface material from the rocky area and profiling the slope, and C3 and C4 type coverings were installed. The complexity of the installation was due to the presence of rock, which meant that anchor bolts had to be used at the top of the slope to hold the topsoil inside the geocell.
