The engineer of record recommended a ground improvement plan that consisted of approximately 100+ cubic yards of compaction grout injected at varying depths. A mixture of cement, fly ash, sand, water, and other admixtures were injected into the loose soils and voids in the limestone and overlying sand strata.
Pumping continued until a grout pressure of 200 to 400 psi was achieved. Injection pins were installed throughout the research lab section of the building per site plan specifications. Each pin pile was hydraulically driven into the soil until enough pressure was reached for refusal.
All operations were performed under the observation of the engineer of record. Efficient planning & coordination was key to overcoming the challenges & limitations. \n\n[/cs_content_seo][/cs_element_layout_column][/cs_element_layout_row][/cs_element_section][cs_element_section _id=”36″ ][cs_element_row _id=”37″ ][cs_element_column _id=”38″ ][cs_element_image _id=”39″ ][cs_element_image _id=”40″ ][cs_element_gap _id=”41″ ][/cs_element_column][cs_element_column _id=”42″ ][cs_element_image _id=”43″ ][cs_element_image _id=”44″ ][cs_element_gap _id=”45″ ][/cs_element_column][/cs_element_row][/cs_element_section][/cs_content]
