The Owner’s Problem: Biogenic Corrosion

The SewperCoat® Solution: the only proven 100% calcium aluminate mortar

When the right conditions exist in a sewer system, Acidophilic* bacteriafeed on sulfur from H2S gas and release sulfuric acid that corrodesconcrete, mortar, steel, and ductile iron. In the most severe cases,bacterial activity can destroy up to 1 inch (25 mm) of concrete per year.

Why is SewperCoat® superior? It’s simple, the right chemistry…SewperCoat®’s outstanding durability in the most severe sewerenvironments relies on the unique “bacterio-static effect” of calciumaluminates. The metabolism of acid-generating bacteria is inhibitedon calcium aluminate surfaces, thus maintaining a pH level above 3.

The unique SewperCoat® equation:much less bacterial activity,much less sulphuric acid production,much less corrosion damage,

… it’s that simple!

“FROM MICROSCOPIC BACTERIA…

…COME BIG PROBLEMS”

Biogenic Corrosion Principles

SewperCoat® provides the Owner with following key benefits:Easy monolithic installationReadily adheres to damp concrete surfacesHigh early strength/High abrasion resistanceRestores structural integrityRock solid barrier to infiltrationEconomical to apply, and cost effective in the long runLasts for generationsSupports sustainable developmentBacked by a no-nonsense 10-year labor and materials warranty

*Acidophilic describes bacterial strains thatdevelop best in acidic conditions. ThiobacillusThiooxidans generates its own sulfuric acid tomaintain its environment to a pH close to 1 onconventional surfaces.

The ease of a cementitious mortar…… with unequalled durability !
