Understanding the types of cracks to choose the right repair tools
Before beginning any repair, it is essential to differentiate between the categories of cracks in order to adapt the tools and techniques. Ravalement Bordeaux – Ravalement33 emphasizes the importance of this preliminary diagnosis. The reasoning is simple: a superficial crack does not require the same equipment or the same approach as a structural crack, the severity of which could affect the stability of the building. The main categories of cracks:
🧱
- Microcracks : less than 0.2 mm, often simply aesthetic. They frequently appear due to the drying of materials or natural shrinkage. 📏
- Fine cracks (crazing): less than 1 mm, they can affect paint or plaster but are not harmful to the structure. ⚠️
- Deep cracks : from 0.2 to 2 mm, sometimes whisker-shaped, suggest more serious movement and require more robust tools. 🏚️
- Structural cracks : wide, penetrating the wall, often accompanied by cracks. Their repair must be immediate and professional to avoid further damage. 🌡️
- Thermal cracks : Associated with temperature variations, they often appear diagonally or vertically. To choose the right tools, it’s necessary to accurately measure the width and depth of cracks. A tape measure, sometimes replaced by a crack gauge, helps track their evolution over time. This assessment is crucial for guiding solutions ranging from simple filler coating to more complex techniques such as resin injection (e.g., Sika). 🔍 Crack Type
