Quantity of grout (if applicable) used to seal the joint. <br />g. Post-grout pressure test results. <br />h. Regrouting and retesting giving above data as required. <br />4. Calculation of the annular space between the lateral tap connection packer and host <br />pipe. <br />5. Manufacturer’s Representative’s Certification per Paragraph 1.02 C. <br />C. Informational Submittals: <br />1. Manufacturer’s product data including handling and storage requirements, <br />application requirements and SDS Sheets <br />2. Manufacturer’s Representative name, contact information, and resume. <br />D. Closeout Submittals: <br />1. Locations of injection grouting, by station and clock position where applicable. <br />1.04 HANDLING AND STORAGE <br />A. Products are to be kept dry, protected from weather, and stored under cover. Products <br />are to be stored and handled according to the MSDS and Manufacturer’s <br />recommendations taking into account actual site conditions. <br />PART 2 PRODUCTS <br />2.01 MATERIALS <br />A. Grout must have the following minimum characteristics: <br />1. While being injected, the grout must be able to react/perform in the presence of <br />water (groundwater) and pumpable over the distance required to install and stage. <br />Minimum of 500 feet. <br />2. The cured grout must withstand submergence in water without degradation and not <br />be biodegradable. <br />3. Catalyzation shall take place at the point of injection/repair. <br />4. Resultant grout formation must prevent the passage of water (infiltration) through <br />the pipe joint or defect. <br />5. After curing, grout must be flexible, under both dry and wet conditions and be <br />chemically stable, resistant to acids, alkalis, and organics found in sewage. <br />6. Residual grout shall be easily removable from the sewer line to prevent blockage of <br />the sewage flow. <br />2.02 PIPE SEALING GROUT <br />A. Pipe Sealing Grout shall be acrylamide, acrylic, or acrylate based and shall have the <br />following characteristics: <br />1. A minimum of 12% base material by weight in the total grout mix. A higher <br />concentration of base material may be used to increase strength or offset dilution <br />during injection.
