Concrete is porous. When left exposed to the elements, it absorbs moisture, carbon dioxide, and chloride ions (especially in coastal areas).

This leads to carbonation - a process where the alkalinity of the concrete drops. When this happens, the internal steel rebar begins to rust. Rust expands, cracking the concrete from the inside out (spalling).

The Solution: Anti-Carbonation Coatings

Specialized protective coatings act as an impenetrable barrier against CO2 and chlorides, while remaining breathable to allow trapped moisture vapor to escape.

By investing in a high-quality protective coating, you can double or triple the lifespan of bridges, parking garages, and structural facades. Speak to Sichern Engineering about our anti-carbonation solutions today.
