Why do cracks form in the wall?
Its causes are diverse and, in general, can arise from expansion, dampness, poor quality of materials, inadequate application of coatings, errors that can be made both in the design and in its execution, etc. One of the most frequent causes is settlement of the building itself.
When are cracks dangerous?
In this case, the most dangerous cracks are those that are typically inclined at a 45-degree angle to the ground. It is also extremely serious if there are cracks in 20% of the structure (even more so if they run diagonally upwards).
Vertical structural cracks are usually caused by minor settlement problems or normal shrinkage phenomena; however, if they exceed 3 mm, this may indicate a more serious settlement problem, which would require an inspection by structural engineering experts.
How can you tell if a crack is serious?
Vertical cracks usually arise due to minor settlement or normal shrinkage. However, if they widen to 3 mm or more, it can be an indication of a serious settlement problem, which would require inspection by structural engineering experts.
When should you worry about a crack?
If you notice cracks that intersect, then you're dealing with a serious pattern. Also, pay attention to cracks where you can insert a pencil, those that run diagonally to the ground, and those that are stair-shaped.
Why do cracks appear in the floor?
The settling of the building to the ground, humidity problems, expansion, quality of materials and the vibration of new constructions, as well as earthquakes are some of the reasons for the appearance of cracks in the floor.
Furthermore, special emphasis is placed on the difference between cracks and fissures: the former has a thickness or opening of more than 1 centimeter, while the latter can measure less than 0.5 centimeters.
Which cracks are more dangerous: horizontal or vertical?
In reality, horizontal cracks are more dangerous than vertical ones because they are less likely to appear. Due to the nature of the wall, a crack should only form from top to bottom.
What is the difference between a fissure and a crack?
A crack is a small, superficial opening. Later in this post, we'll tell you how to easily repair this type of crack. A fissure is a deeper, larger opening that generally affects the entire thickness of the material (brick, ceiling, slab, etc.).
Should I seal cracks in the concrete?
If you notice cracks in the concrete near or inside your home, it's best to seal them. This is because water leaks can cause further damage; in fact, uneven drying will lead to even more damage to the concrete slab than it had initially.
Today, you can find 'plastic cement' capable of sealing or repairing small cracks exposed to the elements; it is highly effective.
