Maccaferri was selected for the supply of DT Mesh in a project on the Durango-Mazatlan Highway
Across Mexico’s Sierra Madre Occidental mountains, the Durango-Mazatlan Highway features a combination of topographical and morphological conditions that produced highly fractured slopes, with 0.75:1 average inclination and approximately 90-meter height. Due to the occurrence of high rainfall, sudden temperature changes and incidence of wind, the area is affected by high weathering of the slopes, resulting in fallen of rocks from 0.1 to 5-meter diameter.
Following an evaluation from the experts of the National Transportation Department, Secretaría de Comunicaciones y Transportes (SCT), the designers in charge of the project proposed to apply Maccaferri double twist wire mesh on the slopes that carried blocks bigger than 0.5 meters, along with 1-meter long anchors installed in a 3×3-meter grid. The DT Mesh in use was then reinforced at specific points with 8-14-meter-long friction anchors and shotcrete.
Maccaferri was selected for the supply of Double Twist Mesh as well as the installation provider. Used for over 50 years, our DT Mesh is a core component of our rockfall mitigation and natural hazard protection engineering solutions. It is engineered from our double twisted hexagonal woven steel wire and is used as a drapery system to prevent rocks and debris from falling onto roads and railways
