How to Protect Structures Against Salt and Chloride Ions?

For structures to last, they must be protected against damage caused by salt and chloride ions. Seaside structures, historic buildings, and reinforced concrete structures are particularly at risk of salt crystallization and corrosion. So, how can we protect structures from these harmful effects?

Damage Caused by Salt and Chloride Ions to Structures

Salinization (efflorescence) occurs when soluble salts within building materials rise to the surface under the influence of water and humidity and crystallize. This condition not only poses an aesthetic problem but also leads to structural deterioration.

Reinforcement Corrosion: Salt and chloride ions reach the steel reinforcement within the concrete, causing rust. Over time, the cross-section of the reinforcement decreases, weakening the load-bearing system.

- Material Deterioration: Salt crystallization leads to expansion and cracking within building materials.

- Hidden Efflorescence: Salts can sometimes accumulate inside the material before reaching the surface, causing greater damage.

Protection Methods Against Salt and Chloride Ions

Salt Cleaning

The first step in preventing salt buildup is removing existing salts from the structure. Specialized products like Restora Desalt effectively remove salts from the surface and pores, extending the life of the structure.

Humidity Control

The most important cause of salt migration is humidity. Waterproofing should be installed in buildings to prevent moisture ingress and reduce humidity levels inside.

Surface Protective Applications

After salt cleaning, hydrophobic (water-repellent) coatings should be used to protect the surface against salt and moisture. This prevents water and salt ions from penetrating the structure.

Precautions Against Chloride Ions

Chloride Barriers: Special chemicals can be used to create barriers that protect the reinforcement against chloride ions.

Corrosion Inhibitors: Chemicals that slow down the rusting of reinforcing steel can be used.
