[vc_row][vc_column][vc_custom_heading text=”Restoration of a seafront staircase (Sori – Genoa area – Liguria region)” use_theme_fonts=”yes”][vc_column_text]Some structures are in poor condition due to various factors: their location, which is also linked to their geographic location, the complexity of the structure itself, and, last but not least, poor maintenance.<\/p>\n

One case that saw the use of PROIND products was the restoration and safety of a seafront staircase located on the eastern Ligurian coast, where the state of the art had obviously concerned both the condominium and the designer.<\/p>\n

The project also involved the use of a company that operates with acrobatic construction techniques, as certain situations presented the obvious drawbacks of applying products in “complex” situations. Therefore, the following issues were addressed:<\/p>\n

    \n
  1. Treatment of corroded reinforcing rods<\/li>\n
  2. Reconstruction of missing parts<\/li>\n
  3. Reconstruction of the steps for the staircase and the “balconies”<\/li>\n
  4. Application of a suitable lime-based leveling compound<\/li>\n
  5. Treatment with water repellent<\/li>\n<\/ol>\n

Treatment of corroded reinforcing bars” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes”][vc_column_text]Regarding the corroded reinforcing bars, we proceeded with the traditional treatment system, cleaning and removing the disintegrated and non-cohesive portions from the bars (also using pressure washers) and then applying SIRIOCEM PF MONO<\/b> cementitious passivator. This intervention obviously involved various portions within the structure and in a wide variety of application conditions.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2668″ img_size=”full” alignment=”center”][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2670″ img_size=”full” alignment=”center”][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2672″ img_size=”full” alignment=”center”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1731415801949{padding-top: 40px !important;}”][vc_column][vc_custom_heading text=”2. Reconstruction of the missing parts” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes”][vc_column_text]The missing sections were reconstructed using SIRIOBETON FA<\/b><\/a> mortar, which proved to be the ideal solution thanks to its characteristics, which offer extremely high adhesion, durability, and waterproofing. This fiber-reinforced, microsilicate-based, shrinkage-resistant mortar is specifically designed for vertical structural repairs.<\/p>\n

    SIRIOBETON FA is ideal for repairing and remediating concrete cover in aggressive environments or those exposed to frequent freeze-thaw cycles, plastering, and structural consolidation of dams or canal banks, viaducts, or highway and railway bridges. It offers the advantages of quick and easy application on vertical surfaces or ceilings, high mechanical strength, strong and immediate adhesion to the substrate, and the ability to apply thick layers (from 1 to 6 cm), with volumetric stability and excellent durability against chemical attack and the action of water, even under pressure.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2681″ img_size=”full” alignment=”center”][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2679″ img_size=”full” alignment=”center”][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”2677″ img_size=”full” alignment=”center”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1731424547808{padding-top: 40px !important;}”][vc_column][vc_custom_heading text=”3. Reconstruction of the steps for the staircase and the "balconies"” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes”][vc_column_text]For both the steps and the balconies, we chose SIRIOBETON FLEX\/M<\/a><\/b> mortar, which offers both effective color and effective protection.<\/p>\n

    SIRIOBETON FLEX\/M is a two-component cementitious compound (with a 3:1 mixing ratio), elastomeric, and waterproof. It is part of the range of products and systems that, when applied, increase the durability of concrete and reinforced concrete structures.<\/p>\n

    From a classification standpoint, SIRIOBETON FLEX\/M<\/strong> complies with UNI EN 1504-2, coating (C) according to the PI, MC, and IR principles (concrete surface protection systems) and UNI EN 1504-9 (products and systems for the protection and repair of concrete structures).<\/p>\n
