Situation 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. Massnahme For the following reasons designers together with the Polish National Roads selected TECCO SYSTEM³ as a stabilizing solution: complicated ground conditions about 12 geotechnical layers were described, only 4 of these were rocks and all others soil in different compositions there was an apprehension that after digging and taking off such mass of material, there will be a release of the energy and consequently, the slopes will be prone to collapse - which is quite common especially for such high slopes the system can be designed and dimensioned against superficial instabilities which offer the possibility to arrange the nails in a more economical way due to the capability of TECCO mesh in absorbing and transferring high loads when slopes stabilized with TECCO SYSTEM³ are combined with anti-erosion mats, they can regain a natural or vegetated appearance, which is aesthetically preferred. 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.

4 Deep cut along the A1 Highway between Pyrzowice and Piekary Śląskie - nailing and flexible facing using TECCO SYSTEM³ ensure safety and a natural look For the cuts along the highway the top down method with benching was applied. The benches were subsequently nailed and covered with TECCO SYSTEM³ To make the nailing as efficient as possible, some subcontractors used drill rigs installed on an excavator. This allowed drilling works flexibility Böschungsstabilisierung A1 Highway Pyrzowice-Piekary Śląskie, PL 4/8
