As the basis of proper project-specific dimensioning and sizing we have performed multiple tests:

• the bearing resistance of the mesh has been ascertained in test series at the Bavarian LGA Regional Trade Institution (Landesgewerbeanstalt) in Germany and at the University of Cantabria in Spain.

• the connections from the TECCO^® mesh to the support rope and rope anchor were tested in a test frame-work in 15 different test arrangements with force and deformation measurements.

The impact of a block of rock at an angle of 30 degrees into the TECCO^® mesh was defined as the endangering rockfall event. Instead of an impact away from the rockface, free fall into the TECCO^® mesh was selected in the test arrangement. The resistance values thus measured and evaluated form the basis for the project-specific dimensioning.
