Identifying and Remedying Concrete Spalling: A Practical Guide

 

Concrete cancer, also known as concrete spalling, can pose a severe threat to your building or structure. But there’s good news – a remedy is available, provided you address it promptly.

 

The cost of repairing concrete spalling / cancer escalates with time. This should not be a concern for conscientious building or project managers who routinely conduct inspections and maintain records. If you’re not already doing this, it’s imperative to start paying attention to concrete spalling risks and issues.

 

Understanding Concrete Spalling and Concrete Cancer

 

To comprehend concrete spalling, we must first delve into the composition of concrete structures. Concrete, being a porous material, incorporates reinforcing steel to enhance its strength. Due to its porosity, it can easily absorb water and salt air, leading to corrosion of the embedded steel.

 

This corrosion process is what triggers concrete spalling. When concrete absorbs water and salt air, it initiates the rusting of the steel within. As the steel corrodes, it expands, causing cracks in the concrete.

 

The development of these cracks accelerates the concrete cancer, as it exposes more of the steel, significantly weakening the structural integrity of the building. The term “cancer” is employed because, much like a disease, if left untreated, the damage will progress rapidly and become increasingly severe. Therefore, early intervention is crucial.

 

How To Spot Signs of Concrete Deterioration

 

Identifying concrete deterioration, commonly known as concrete cancer, is essential to prevent serious structural damage. Fortunately, recognizing the signs is relatively straightforward. Regular inspections are key to catching the issue early. Here are some of the most common indicators:

 

  1. Cracks in the concrete.
  2. Sections of the concrete showing signs of crumbling.
  3. Rust stains on the concrete surface.
  4. Detection of leaks within the concrete.
  5. Bubbling or blistering on the concrete.
  6. Noticeable expansion of the concrete.

 

By consistently watching for these signs, early detection and prompt action can significantly reduce repair costs and prevent extensive damage to your building or structure. If you do spot any of these signs, it is advisable to consult a professional for a thorough diagnosis.

 

 

Professional Evaluation and Diagnostic Analysis

 

It’s essential to remember that only a qualified concrete professional can provide a comprehensive diagnosis for your concrete issue. When you observe a sign such as a crack or rust stain, your initial thought shouldn’t jump to “concrete cancer.”

 

Instead, it should prompt you to recognize the need for professional assessment. A concrete expert will accurately identify the root cause of the problem and recommend an appropriate solution to address it effectively.

 

Concrete Spalling and Concrete Cancer Causes

 

Concrete cancer, also known as concrete spalling, can be attributed to several factors, with moisture being the primary cause. To gain a comprehensive understanding of potential triggers for concrete degradation in your building or structure, consider the following:

 

  1. Inadequate Waterproofing: Inefficient waterproofing systems can allow moisture to infiltrate the concrete, accelerating the deterioration process.

 

  1. Exposure to Salt Air and Chlorides: Structures located near the ocean or rivers are susceptible to concrete cancer due to the corrosive nature of salt air and chlorides.

 

  1. Building Defects: Poor construction practices and defects in the initial building process can contribute to concrete cancer over time.

 

  1. Environmental Factors: Humid or rainy weather conditions, combined with general wear and tear, can exacerbate concrete deterioration.

 

  1. Low-Quality Concrete: The use of subpar concrete materials in construction can increase the risk of concrete cancer.

 

  1. Shifting Earth Foundations: Buildings constructed on foundations prone to movement and shifting may develop cracks, which can facilitate the onset of concrete cancer.

 

Structures most vulnerable to concrete cancer are those exposed to these factors. While older buildings, typically over a decade old, are at a higher risk, it’s essential to remain vigilant in identifying signs of concrete cancer, even in newer constructions.

 

 

Buying a House with Concrete Cancer:

 

Buying a house or building with concrete cancer can be financially risky. Discovering concrete cancer after your purchase can lead to significant concrete repair expenses. Therefore, it’s advisable to inspect thoroughly before making a commitment.

 

 

 

Concrete Maintenance vs. Repair Work:

 

Regular maintenance is essential to prevent major repair costs. Coating your concrete with waterproofing and conducting routine inspections can save you from costly repair bills later on.
