The Project
The City of North Las Vegas recently undertook the Sloan Channel RCB Repair Project, which involved the installation of a pipe liner within an existing reinforced concrete box along the Sloan Channel alignment, extending from the City’s Water Reclamation Facility (WRF) to its confluence with the Las Vegas Wash. A critical aspect of this project was the need to address the irregular void space left by the new liner, which required careful grouting with a flowable fill to ensure structural integrity.
A notable highlight of this project was the use of Class III cellular concrete for the annular grouting process. Over the course of the project, our team performed 3 miles of grouting, with the longest reach exceeding half a mile from the injection point to the vent location. This innovative approach was meticulously calculated to prevent any damage to the existing pipe by managing the pressure applied during the grouting process. In total, more than 2,500 cubic yards of cellular concrete were utilized, effectively filling the voids and reinforcing the channel infrastructure. This project not only enhances the durability of the water system but also showcases the advantages of using advanced materials like cellular concrete in critical infrastructure repairs.
