Concrete Pitting, Flaking, & Staining

Understanding Common Concrete Problems: Pitting, Flaking, and Staining

Though it is sturdy, concrete isn’t impervious to damage. Over time, various factors, both external and internal, can compromise its integrity. 

Concrete Pitting 

Pitting appears as tiny dents or depressions on the concrete surface. They may appear as small pockmarks or holes in the concrete surface, which can collect debris and make the surface unstable.  

Discoloration and Staining

Uneven color or patches on your concrete indicate discoloration, which can result from several factors, including vehicle oil. Some of these factors can significantly weaken concrete over time.  

These issues may appear on a range of concrete surfaces, including:  

Causes of Pitting, Flaking, and Discoloration 

Concrete, as strong as it may seem, has its vulnerabilities. By understanding the root causes of common issues like pitting, flaking, and staining, homeowners can take proactive measures to maintain their surfaces. 

Causes of Pitting 

Pitting, characterized by small indentations on the concrete surface, can be attributed to: 

• Air Entrapment: Air bubbles trapped during the pouring and setting process can lead to pitting once the concrete dries. 
• Corrosive Chemicals: Prolonged exposure to chemicals, especially de-icing salts, can erode the surface. 
• Abrasion: High-traffic areas, especially those exposed to heavy machinery or sharp objects, are more susceptible to pitting. 

Concrete Flaking and Its Origins 

Flaking, the process where layers of concrete start to chip off, often results from: 

• Water Damage: Repeated freeze-thaw cycles can cause water to expand within the concrete, leading to flaking. 
• Poor Concrete Mix: Insufficient cement in the mix can lead to a weak top layer that is prone to flaking. 
• Rapid Drying: If the concrete dries too quickly after being poured, the surface can become weak and flaky. 

Causes of Discoloration 

Concrete discoloration can manifest as uneven shades or prominent patches and can be due to: 

• Inconsistent Curing: If parts of the concrete dry faster than others, it can lead to uneven coloring. 
• External Contaminants: Spills, mold growth, or tannins from leaves can stain the concrete. 
• Variation in Mixtures: If different batches of concrete are used for a single surface, it can result in varied shades once the concrete dries. 

Awareness of these causes allows homeowners to take preventive action, ensuring the longevity of their concrete installations.

Concrete Pitting, Flaking, and Staining FAQs

How often should I check my concrete for damage?

We recommend inspecting your concrete at least once a year, and more often if you notice sudden changes such as new cracks, sinking, or surface wear. If you’ve had concrete lifting completed, an annual service visit can help ensure your concrete stays protected long-term. Contact JES to learn more and schedule a free concrete inspection.

How quickly can concrete pitting get worse?

Concrete pitting can take years to appear, but once it starts, it often progresses quickly and can lead to cracking, flaking, and surface deterioration. Addressing the issue early helps prevent more extensive damage and costly repairs.

How can I prevent concrete pitting, flaking, and staining?

To help prevent concrete pitting, flaking, and staining, limit the concrete’s exposure to water by improving drainage so that runoff flows away from slabs. In winter, shovel snow promptly and maintain gutters and downspouts to reduce freeze-thaw damage and excess moisture.
