Corrosion is the primary cause of failures in concrete.  When water reaches reinforcing steel the corrosion process begins. Corrosion produces iron oxide (rust). Rust is an expansive force that causes cracking in concrete.                

Cracking provides a pathway for water and environmental contaminants to reach rebar which results in more corrosion in a continuous cycle that can lead to costly repairs.  Repairs to concrete should always include treating rebar with an anti-corrosion coating.        

ECB (Electro-Chemical Barrier) incorporates zinc technology to prevent corrosion using sacrificial chemistry in addition to passive and integral anti-corrosion chemistries.           

ECB can be left uncovered on rebar for up to 30 days simplifying job site scheduling.
