At Lerici in Liguria a hiking path under the famous Castle di San Terenzo was endangered by rockfalls from the slope above.
Mica schists, phyllite.
As a solution active slope stabilization with nailing and TECCO® System was applied (with a smaller mesh opening band at the top). With a slope ranging from 60 ° to 80 ° the nail pattern is 3.0 x 3.0 meter, with nails of 28 mm in diameter. To ensure the stability of the debris cover, the nails have been drilled to a depth of 3 meter.
Due to high corrosion resistance requirements (coastal area), special mesh was chosen: TECCO® System 45/2 STAINLESS.
