The Polish A1 highway connecting Poland from south to north leads through Silesia. Because of the morphology of the terrain, deep cuts were required. Due to geological conditions and also due to the fact that this area is strongly influenced by the hard coal mining activity, slope stabilization was a must.
For the following reasons designers together with the Polish National Roads selected TECCO® SYSTEM³ as a stabilizing solution:
TECCO® SYSTEM³ was designed to protect local instabilities of soil and rock masses. This worked perfectly, as first visible small movements occurred which were stopped by the TECCO® mesh shortly after installation.
