What is Concrete Scaling/Flaking and How do I Prevent It?
What is Concrete Scaling?
Scaling is a fairly common problem with concrete. It refers to the flaking or peeling of a hardened concrete surface, typically due to repeated exposure to freeze/thaw cycles.
Scaling occurs when parts of the concrete surface start to flake or chip away, eventually exposing the coarse aggregate below. While light scaling does not expose the coarse aggregate particles below, very severe scaling (the most extreme version) is marked by surface mortar erosion, coarse aggregate loss, and surface loss that exceeds 20 mm.
In addition to harsh freeze-thaw cycles, concrete that is not properly air-entrained will result in scaling as well. Deicing chemicals can also accelerate and worsen scaling. Poor finishing practices are also a known culprit that can lead to scaling in the future.
Scaling typically starts in one area of the concrete, but if left untreated, it can expand to others.
What Do I Do About It?
While scaling can be addressed after it’s begun, it’s wiser to prevent it beforehand. Fixing it yourself can be a huge undertaking if it’s a DIY project and calling in a professional will cost you money.
A high-quality concrete mix, topical or integral sealer, and strengthening fibers can reduce the chances of scaling in the first place. Ozinga’s OzFlat series includes all of the above and much more:
- OzingaShield integral sealer that protects your concrete flatwork from day one
- 4000-5000 PSI (5-8% air)
- Micro fibers (available in OzFlat standard and OzFlat Premium)
- Water reducer
- Plus many more benefits
