Definition - What does Rebar Corrosion mean?

Rebar corrosion refers to the corrosion of reinforcement bars present in reinforced concrete sewer and water pipes. Corrosion primarily weakens a pipeline by attacking its structure, making it susceptible to pits, cracks, and fractures. Corroded pipes if not repaired can lead to rupture of the pipeline.

Materials such as high-density polyethylene (HDPE), polyvinyl chloride (PVC) and glass-reinforced plastic (GRP) can be used to replace damaged pipelines using trenchless rehabilitation methods such as sliplining and pipe bursting. These materials never corrode, are flexible and easy to maintain.

Trenchlesspedia explains Rebar Corrosion

Corrosion can be controlled using cathodic protection, corrosion inhibitors, and the use of corrosion-resistant materials. Cathodic protection uses direct current to fight the corrosion in a metal pipeline. It can also prevent corrosion from beginning in a new pipeline and prevent existing corrosion from getting worse.

Corrosion inhibitors are chemicals that are added to the environment surrounding the affected pipeline in order to curb the attack. These can also help in extending the serviceable life of the pipeline and prevent failure of pipeline.

Materials such as high-density polyethylene (HDPE), polyvinyl chloride (PVC) and glass-reinforced plastic (GRP) are excellent materials that never corrode, are flexible and easy to maintain.
