Concrete Enhancement & Anti-Corrosion.
Stop chloride-induced corrosion before it eats the reinforcement.
What it is
Concrete Enhancement & Anti-Corrosion, defined.
Anti-carbonation coatings, sacrificial galvanic anodes, and corrosion-inhibitor impregnation for reinforced concrete in coastal and aggressive environments.
Reinforced concrete in coastal Nigeria fails by chloride-induced corrosion of the rebar. Salt enters through the cover concrete, depassivates the steel, and the corrosion product expands - bursting the cover off the structure. Anti-corrosion work is about getting ahead of that process, or arresting it before it spreads.
