Pressure Grouting
Pressure Grouting is the term used to describe the pressurized injection of a sealant into an underground leaking pipe joint which penetrates and stabilizes the surrounding soil and permanently stops ground water from entering the joint. Pressure Grouting is performed from the inside of the pipeline with the aid of a special video camera to inspect the pipeline and to accurately position a joint sealing apparatus known as a "packer" over a leaking joint.
This new and revolutionary method of internal pipeline inspection and repair was the vanguard of the "trenchless technology" industry. For the first time, municipalities and private industry could actually see, in real time, the operation of their waste and storm water pipeline and make informed decisions regrading preventative maintenance.
To this day, the Pressure Grouting Process is considered the most effective, cost efficient method of permanently stopping ground water infiltration into wastewater pipelines. By embracing this technology, municipalities and private industry, worldwide, have realized tremendous savings in their underground infrastructure maintenance and wastewater treatment costs.
