In coastal regions surface water can contain high concentrations of salt which adds another component which not only can damage concrete but also can corrode steel.

Concrete structures such as bridges and buildings normally contain steel reinforcement. Generally, steel is chemically passive in concrete because of concrete's alkalinity, but it isn't immune to corrosion. That is, the rate of corrosion can be so low that normally we can neglect it for all practical purposes. But if conditions change, the corrosion rate could increase to problematic proportions.

The corrosion process requires water, oxygen from air, and a catalyst such as salt. Steel won't corrode in dry reinforced concrete, even if salt is present, nor will it in wet concrete, even in the presence of chloride ions, which are in salt solutions, if oxygen is essentially unavailable, for instance, at great depths under the ocean surface.

Concrete above the water level stays completely dry

As one can see, if one these component is missing the concrete is safe for a long time.

On a freestanding concrete structure, it is pretty hard to keep the salt away which may be in the air as salt spray. Oxygen is also all around us. The only possible option to protect concrete in such situations, is to keep the water away.

Keeping the water absorption low has also a significant effect on the way concrete treated with 3001 can handle  frost, thawing in strong winter conditions.

This image shows the comparison of concrete treated and untreated after 50 freezing and thawing cycles in a lab test.

Nanovations 3001 can protect the concrete from water and water soluble salt and other contaminations.

By becoming permanent part of the concrete, the durability is pretty much as high as the concrete itself.
