Chemical Grouting and Decommissioning in Metro Vancouver
Chemical grouting is an effective and proven method of pipe rehabilitation. It stops groundwater from entering the sewer pipe through openings in manholes, joints, or connections. ABC Pipe Cleaning Services Ltd provides efficient chemical grouting for maintenance or pipe decommissioning in Vancouver and the surrounding areas.
Understanding Chemical Grouting and Decommissioning.
Chemical grouting and decommissioning play a fundamental role in maintaining the integrity of pipelines and sewer systems. Grouting is conducted to prevent water infiltration, which prevents damage and extends the lifespan of unground structures. Decommissioning is performed to safely seal unused connections, preventing leaks and environmental contamination.
The Chemical Grouting Process
Before applying chemical grout, we perform joint testing so that we can identify leaks or defects in the pipe system. This process may use water or air pressure to ensure each joint is watertight. If a joint fails the test, chemical grout is injected for effective sealing and to prevent groundwater infiltration, contributing to the overall integrity of the sewer system.
The Solution for Many Situations
Grouting Decommissioned Connections
Services that are no longer in use or required are decommissioned. Instead of capping the abandoned service, sometimes the city also requires that the service be filled with grout. Should you need this done, we can easily use our truck-mounted grout system. Call us for a quote.
Surface Interface Grouting
Sometimes the pipe leaks where the service pipe connects to the mainline pipe (a.k.a. the interface). We have the equipment to stop infiltration at the interface. After isolating the interface, grout is pumped into it and then tested to make sure it has been sealed.
Mainline Grouting
Sometimes the pipes have faulty joints or cracks. In these cases, the joints are air-tested first. If it fails the air test, then grout is pumped into the joint (or crack). The grout forms a gel that helps prevent water coming into the pipe. As long as your pipes are 150 mm (6”) to 1050 mm (42”) in diameter, we can seal it. The joint is retested after the grouting process. The procedure is repeated until the joint has passed the air test.
About the Grout
Materials
-
Acrylamide – This type of chemical has been used for many years in North America with great success.
-
Urethane – This premixed grout is easy to apply and has great compressive strength.
