Site Assessment: Identify the source of the leak or areas where waterproofing is needed.Assess the type and severity of cracks or voids.Determine the appropriate grout material and pressure required for the job.

Preparation: Clear the work area of any debris and ensure it is clean and dry.If necessary, drill holes or ports into the structure at the locations where grout will be injected. These holes should be spaced appropriately and reach the desired depth.

Mix the Grout: Prepare the grout mixture according to the manufacturer's instructions. The consistency of the grout should be appropriate for injection.

Setup Injection Equipment: Attach the grout hoses and injection ports to the grout pump or injection packers.Ensure all connections are secure.

Start Injection: Begin injecting the grout into the prepared injection holes or ports.Monitor the pressure gauge to ensure that the grout is injected at the recommended pressure.Continue injecting grout until the cracks, voids, or voids are filled or until the specified quantity of grout has been used.

Reinjection and Testing: In some cases, you may need to wait for the initial injection to set and then perform a second injection to ensure all voids are properly filled.Conduct pressure testing to confirm that the waterproofing is effective. This may involve monitoring the pressure and checking for any signs of grout leakage.
