Concrete Pitting, Flaking, & Staining

Understanding Common Concrete Problems: Cracks, Pitting, Flaking, and Discoloration 

Concrete, as sturdy as it is, 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 gather debris and present an unstable surface.  

Flaking Concrete 

Flaking is the peeling or chipping away of the concrete’s top layer. When this continues, it can eventually degrade the concrete surface until it’s no longer smooth or waterproof.  

Discoloration and Staining:  

Uneven color or patches on your concrete indicates discoloration, which can be the result of several factors, some of which can significantly weaken concrete over time.  

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

• Driveways 
• Sidewalks 
• Pool decks 
• Porches 
• Patios 
• Steps 

Causes of Pitting, Flaking, and Discoloration 

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, 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 dried. 

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