Micropiles were installed to a depth range of 45-50 feet below existing grade. The support brackets for the micropiles allow not only prevention of further settlement of foundation elements but also can be utilized to provide some uplift of foundation elements. Chemical grout injections were completed to give additional support to the foundation. Efficient planning & coordination was key to overcoming the challenges & limitations. Helicon collaborated with the Geotechnical Engineer of Record throughout the work and confirmed all recommended criteria were followed. \n\n[/cs_content_seo][/cs_element_layout_column][/cs_element_layout_row][/cs_element_section][cs_element_section _id=”39″ ][cs_element_row _id=”40″ ][cs_element_column _id=”41″ ][cs_element_image _id=”42″ ][cs_element_image _id=”43″ ][cs_element_gap _id=”44″ ][/cs_element_column][cs_element_column _id=”45″ ][cs_element_image _id=”46″ ][cs_element_image _id=”47″ ][cs_element_gap _id=”48″ ][/cs_element_column][/cs_element_row][/cs_element_section][/cs_content]
