Over the past 15 years this steep slope, located within the Antisana National Park in Ecuador, had experienced several failures. Due to its remote location, the slope presented many logistical and operational challenges. Materials had to be transported by helicopter and the site could only be reached on foot.
Difficult access to the slope face meant that all equipment and installation teams had to be connected to abseil points. To stabilise the slope, 220 Platipus B4 anchor systems were installed to a depth of 8m, using a core drill rig with mounted compressor. In addition, 20 Plati-Drains were installed to reduce pore water pressure and increase stability. Over 820m2 of HPTRM was then placed across the entire slope face and secured in position using load plates and load nuts to complete the installed B4 anchor systems. A further 200 Platipus S2 ARGS Systems were installed to hold the HPTRM tight to the slope surface to provide erosion control measures and encourage re-vegetation.
