Internal, or chemical, grouting is the most common method for sealing leaking joints in structurally sound sewer pipes.

Using special techniques and tools, chemical grouts can be applied to pipeline joints, manhole walls, wet wells in pumping stations, and other leaking structures. Small holes and radial cracks also may be sealed by chemical grouting.

Chemical grout has been used to stop leaks in sewers, manholes, tanks, vaults, tunnels and many other applications all over the worls. Grouting is a long-term defense against infiltration of groundwater into structurally sound sewer systems.

Many different processes are available for structural rehabilitation of pipelines, manholes and even service laterals. Stopping leaks with chemical grout will result in much stronger pipes with more uniform wall thickness.

Every step of the test and seal operation can be recorded on video tape to provide a permanent record of the exact condition of the pipeline..
