Chloride contamination in concrete, at the reinforcing steel, aggressively stimulates corrosion. How can it be arrested?
Chlorides are soluble and reactive. They enter concrete via constant movement of moisture, in and out of the capillary pores. Chlorides, together with oxygen and moisture, reach the embedded steel and set up electrochemical corrosion in the rebar.
Untreated steel corrosion will cause the concrete to break down well short of its planned service life. Marine structures are at particular risk because of the high chloride levels in the seawater.

How can the process be halted?
MARKHAM offers penetrating hydrogel treatment, the advanced and effective solution. This treatment penetrates deep into the porosity of the concrete, setting up a barrier against incoming moisture, and immobilizing the movement of chlorides and reducing oxygen.
This very effectively arrests the chemical process driven by the chlorides, protecting the rebar and restoring the concrete’s natural durability.
If you are responsible for the care of concrete structures in marine or other high-risk environments, get in touch with the friendly MARKHAM team today! We’re keen to talk about pro-active protection and maintenance solutions.
