Sewer Joint Test and Seal Systems and Equipment

General Information
ARIES Joint Test and Seal Systems are used to test the watertight integrity of clean structurally sound pipelines and line joints. Each sewer line section or joint is isolated using an inflatable test device called a packer. Air is injected at a controlled pressure into the isolated area and then shut off. A pressure transducer measures the isolated area pressure over a set time period. If the pressure remains constant or there is only a small pressure drop, the line or joint is considered good. If the isolated area cannot hold the air pressure, it is considered a failure and sealing chemical grout is injected into the isolated area. When located, the leaks are stopped by injecting a chemical soil sealing grout that stabilizes the soil and fills voids outside of pipe and stops ground water flow through the soil.

Packers
ARIES systems operate with all standard main line and lateral grout packers for six inch and larger lines. ARIES systems are supplied with LOGIBALL brand packers.

Remote Pressure Sensing System
All packers use the void pressure sensing transducer. Any void pressure change is transmitted electronically to an LED readout on the control panel and is shown on the TV screen. The control panel is equipped with a timer system so that void pressure changes can be monitored for a selected time period. The sensing system allows constant monitoring of void pressure during air pressure testing and chemical injection sealing.

Grout Materials
Grout begins its sealing process as two separate liquid chemicals. Each chemical is pumped through a hose and packer to leaking cracks and pipe joints. Here they flow through the cracks or joints, into the surrounding soil where they combine with each other and the soil to form a gel. The gelled mass forms a waterproof collar around leaking pipes. Infiltration and exfiltration cannot penetrate the mass. This watertight collar adheres to the outer surface of a pipe and stays there unless removed by excavation.ARIES equipment operates with all commonly used grouting materials.

Sewer TV, Test and Seal Truck
Test and seal procedures are performed from a sewer TV inspection truck equipped with remote pressure test and seal equipment. The truck contains all of the equipment necessary to inspect and test pipes, mix and inject grout, and clean and store materials.
