Concrete Pitting, Flaking, & Staining

Homeowners take pride in the appearance of their homes, and concrete driveways, porches, and other surfaces are no exception. 

Concrete damage, like pitting, flaking, and staining, can undermine the visual appeal and the structural integrity of a home. While they may seem minor at first, these problems can indicate more substantial underlying issues that require attention. 

BQ Basements & Concrete understands these challenges and provides dependable solutions to safeguard your property’s value and aesthetic. Our innovative SettleStop™ PolyRenewal™ Injection concrete lifting system addresses the underlying issues and ensures they won’t return. 

Learn more about concrete pitting, flaking, and staining and how professional concrete lifting is vital to your home’s safety and longevity. 

What Is Concrete Pitting, Flaking, and Staining? 

Concrete pitting, flaking, and staining are interrelated surface defects caused by common underlying causes, such as poor concrete mix, inadequate curing, and exposure to harsh chemicals or weather conditions. 

Concrete Pitting 

Concrete pitting is a form of concrete surface deterioration that appears as small, coarse, uneven craters. Pitting is caused by errors in concrete production, such as using too much water or not enough cement. Concrete pitting can signal internal structural weakness and lead to cracks and other concrete damage. 

Concrete Flaking 

Concrete flaking is a surface condition that exhibits thin layers of concrete peeling or flaking. It is caused by exposure to elements like moisture and weather, which can weaken the concrete and make it more susceptible to damage. Concrete flaking can lead to surface erosion and other damage, so it is important to repair it promptly. 

Concrete Staining 

Concrete staining is a discoloration of the concrete surface caused by external agents like chemicals, oil, mud, or food. It can also be caused by ultraviolet (UV) ray exposure from the sun. Concrete staining can compromise the concrete’s integrity over time, making it more susceptible to water seepage and other damage. 

Despite their unique characteristics, these problems have a common denominator—they all indicate that the concrete is in a compromised state. If left unattended, these surface-level issues will continue to deteriorate over time. 

Concrete pitting, flaking, and staining are often accompanied by additional damage, such as cracking and sinking. These issues develop on various surfaces, including: 

Continued neglect of these surfaces will lead to further deterioration.  

What Causes Concrete Pitting, Flaking, and Staining? 

Concrete pitting, flaking, and staining are all signs of compromised structural integrity, but they have different underlying causes. Early detection and repair can help prevent further damage and extend the lifespan of your concrete structure. 

Causes of Concrete Pitting 

Concrete pitting is caused by a variety of factors, including errors in the initial mixing process, mishandling during curing, using too much water in the concrete mix, and exposure to harsh chemicals or weather conditions.  

Improper mixing and curing can lead to air pockets in the concrete, which weaken it and make it more susceptible to pitting. Using too much water in the concrete mix dilutes and weakens the concrete, making it more susceptible to pitting.  

Concrete pitting is often not immediately noticeable. It can take several years for pits to become visible. However, once pitting begins, it progresses rapidly. 

Causes of Concrete Flaking 

A variety of factors influence concrete flaking. When moisture infiltrates concrete over time, it interacts with alkaline compounds, leading to surface erosion and flaking. Exposure to natural elements, such as sunlight, extreme temperatures, and weather conditions can expedite this process. Also, improper concrete mixing, curing, and finishing techniques can heighten the susceptibility to flaking.  

Inadequate drainage can result in pooling water on concrete surfaces, enabling seepage and contributing to flaking. High-traffic concrete areas like sidewalks and driveways are more prone to flaking over extended periods. Additionally, internal defects in concrete, such as air pockets and voids, can also cause flaking. 

Causes of Concrete Staining 

Concrete staining occurs when external agents like oil, mud, chemicals, or food discolor the surface. This can potentially alter the concrete’s chemical makeup, compromising its integrity over time and making it more susceptible to water penetration, cracks, and other damage.  

Understanding and addressing concrete pitting, staining, and flaking efficiently is crucial for achieving long-lasting repair.  

BQ Basements & Concrete specializes in providing tailored, durable solutions. Our expertise ensures precise and effective remedies for your peace of mind. 

Can You Fix Concrete Pitting, Flaking, and Staining? 

Yes, concrete pitting, flaking, and staining is reparable. However, it’s vital to adopt a comprehensive approach for lasting results. Surface coatings and patching are short-term fixes. To establish a lasting solution and prevent future issues, you must address the underlying causes. 

After an expert identifies the underlying concrete issues, you can proceed in the professional repair process.  

How to Fix Concrete Pitting, Flaking, and Staining 

At BQ Basements & Concrete, we don’t rely on typical methods like patching or pouring. Instead, we use an advanced solution called PolyRenewal™ polyurethane injections. These injections stabilize the ground underneath and lift troublesome concrete slabs, providing a superior, long-lasting fix. 

This unique repair method includes the following essential steps: 

  • Conduct a comprehensive, free inspection to pinpoint the underlying problem. 
  • Carefully bore small holes, about the size of a penny, into the concrete. 
  • Securely install injection ports into the drilled openings. 
  • Prepare our exclusive closed-cell foam mixture. 
  • Infuse the high-density polyurethane foam beneath the concrete surface. 
  • Allow the foam to solidify (typically within 15 minutes). 
  • Verify that the concrete is lifted and securely stabilized. 
  • Carefully extract the injection ports. 
  • Fill and smooth the drilled holes. 
  • Seal all cracks and joints to prevent further damage. 
  • Conduct routine inspections and maintenance to ensure the concrete’s endurance. 

BQ Basements & Concrete has exclusive products to ensure homeowners receive customized, high-quality solutions. Our PolyRenewal™ system offers exceptional support, safeguarding the durability of your concrete.
