The heterogeneous and fractured nature of the excavated materials has reduced slope strength, increasing susceptibility to shallow failures.<\/p>\n\n<p>During heavy rainfall, surface erosion, raveling of loose rock fragments, and localized detachment of weathered material were observed. These conditions not only threaten long-term slope stability but also pose safety risks to road users from potential rockfall and debris on the carriageway.<\/p>\n\n<p>With growing regional traffic and the need to ensure uninterrupted expressway operations, a durable and reliable surface-stabilization solution was required.<\/p>\n\n<h5 class=\"wp-block-heading\"><strong>The Solutions<\/strong><\/h5>\n\n<p>Maccaferri\u2019s <strong>MacMat\u00ae HS<\/strong> was selected as the primary surface-strengthening system. MacMat\u00ae HS is a high-performance erosion-control and slope-reinforcement geomat that combines a three-dimensional polymer matrix with high-strength steel mesh, delivering both surface protection and mechanical reinforcement.<\/p>\n\n<p>Installed directly onto the slope face, the system effectively confines loose and weathered material, preventing raveling and small rock detachment. Its high tensile capacity allows it to bridge minor discontinuities and restrain unstable surface layers, significantly reducing the risk of shallow failures.<\/p>\n\n<p>The geomat\u2019s three-dimensional structure also promotes vegetation growth, enhancing long-term erosion resistance and slope stability.ectivity. The completed works reinforce the surrounding landscape, enhance road safety, and support reliable operation for decades ahead.<\/p><\/div><div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\"><div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\"><div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><figure class=\"wp-block-image aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1200\" height=\"788\" src=\"https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4.png\" alt=\"\" class=\"wp-image-97609\" style=\"width:773px;height:auto\" srcset=\"https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4.png 1200w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4-300x197.png 300w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4-1024x672.png 1024w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4-768x504.png 768w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/2-4-120x79.png 120w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n<div style=\"height:22px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img decoding=\"async\" width=\"1200\" height=\"788\" src=\"https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4.png\" alt=\"\" class=\"wp-image-97606\" style=\"width:773px;height:auto\" srcset=\"https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4.png 1200w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4-300x197.png 300w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4-1024x672.png 1024w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4-768x504.png 768w, https:\/\/www.maccaferri.com\/my\/wp-content\/uploads\/2025\/11\/1-4-120x79.png 120w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n<div style=\"height:22px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div><\/div><\/div><\/div><\/div><p><\/p>","protected":false},"excerpt":{"rendered":"<p>Turning Challenging Landscapes Into Safe, Lasting Infrastructure<\/p>\n","protected":false},"author":28453,"featured_media":97610,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_joinchat":[],"footnotes":""},"categories":[1],"tags":[],"class_list":["post-97613","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.0 (Yoast SEO v27.0) -
