The project was complemented by preliminary drilling, installation of steel reinforcement, anchors and soil nails using self-drilling bars, and sprayed concrete lining to protect the exposed surfaces. <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Operational challenges<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The works were carried out in a constrained urban environment, requiring careful management of interferences with existing infrastructure and continuity of operations in restricted spaces. Particular attention was paid to injection parameter control, correct column overlap and the management of works in heterogeneous soils. <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Results<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The project improved the mechanical properties of the ground and provided the stability required for the planned works. Coordinated use of different ground improvement technologies allowed the site to operate effectively despite urban constraints and service interference, while maintaining continuity and control throughout construction. <\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"1024\" data-id=\"619\" src=\"https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1-576x1024.webp\" alt=\"\" class=\"wp-image-619\" srcset=\"https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1-576x1024.webp 576w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1-169x300.webp 169w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1-768x1365.webp 768w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1-864x1536.webp 864w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-2-1.webp 1148w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"1024\" data-id=\"618\" src=\"https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4-576x1024.webp\" alt=\"\" class=\"wp-image-618\" srcset=\"https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4-576x1024.webp 576w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4-169x300.webp 169w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4-768x1365.webp 768w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4-864x1536.webp 864w, https:\/\/cosidra.com\/wp-content\/uploads\/2026\/04\/sestri-levante-4.webp 1148w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Works completed: Project overview In the municipality of Sestri Levante, Cos.Idra carried out ground improvement works in an urban setting characterised by limited working space and the presence of existing utilities.
