Concrete degradation often refers to the damage inflicted by the rusting of steel in the reinforced concrete. As a result, concrete might crack and or crumble off. Degradation weakens the concrete foundation and may result in collapse.
The cause of concrete degradation is often the penetration of carbon dioxide (CO²), a process called carbonation. Another reason for concrete degradation is chlorides penetration.
Penetration by chlorides is often linked to de-icing salt. Thus, viaducts, bridges, and loading docks are especially susceptible to concrete degradation. The reinforcing steel was, in the sixties and seventies, less deep into the concrete structure. Therefore, buildings from that time period are more susceptible to concrete degradation.
The penetration of chlorides can also cause concrete degradation; this happens more often in a humid sea climate.
Borèl protects against carbonation
Due to its porous nature, concrete allows for oxygen and moisture to reach the reinforcing steel. This increases the risk for carbonation.
Moxilon 200 nano Hydro / Colour is the solution for the concrete porosity. Additionally, concrete becomes impenetrable by moist and oxygen. Borèl guarantees such impenetrability for 20 years.
Recognising concrete degradation
The presence of big red-brown rust stains around the reinforcing steel and tears and or concrete crumbling indicate concrete degradation.
Fixing concrete degradation
To treat degraded concrete, one needs to remove and replace the concrete corroded parts. Treating degraded concrete might also involve the placement of new reinforced steel. A combination of the Moxilon 200 Nano hydro / Colour in combination with cement based repair mortar is used to repair degraded concrete.
