Overview of the construction site - on the right the old solution with visible gabion mesh which turned out to be not sufficient for the conditions. TECCO® SYSTEM³ was designed to be placed over the old layer of mesh

Year of installation

2017

Situation

The revision works at the railway line no. M202 Zagreb-Rijeka were done together with the installation of a slope protection system. In the past, regularly occurring rock falls limited the speed of the trains.

Geology

Limestones covered by scree

Description

When designer Vanja Kovačević received data from the geologist, he chose TECCO® G65/4 for this slope protection. TECCO® G65/4 was combined with 4 meters long self-drilling nails (32/21 mm) and 6 to 14 meters long nails (51/34.3 mm).

This is the first TECCO® G65/4 installation in Croatia.
