What Are The Possible Causes Of Wall Cracks?

Plastering poorly executed: In this case, what counts is the good service of the professional who prepares and applies the plaster. A wrong amount of material and poor application can lead to the appearance of wall cracks ( รอยร้าว ผนัง which is the term in Thai) that will reach the plaster and paint.

Meeting of two different materials: The fact that they react differently to dilation can cause them to separate over time, causing cracks.

Oscillation of temperature: With the change of temperature, the materials can increase or decrease in size, making the surfaces susceptible to the appearance of cracks.

Construction overload: The work of the calculating engineer is essential to ensure the correct load distribution of a construction. When the weight of the construction is greater than the weight supported by its base, the structural elements begin to give warning signs through the cracks.

Hydroscopic variation: That is, constant exposure to periods of drought and humidity can cause dilations and tractions that give rise to cracks.

Poor sizing of the foundation: When the construction base is poorly dimensioned, it can move and sink into the ground, causing cracks in various structural components of the property.

How to repair them?

Superficial cracks, present only in plaster and paint, are easy to repair. Check the area affected by the crack and remove any plaster that is not entirely adhered to the wall. Scrape the material and perform new coverage and painting later. The deepest cracks that affect masonry and structural elements, on the other hand, must be evaluated by an expert to prove the cause and treat the problem. In this case, the repair may vary according to the location and severity of the problem. In other words, it can range from filling and covering the openings with flexible materials to reinforcing the structure in the most extreme cases.

How To Avoid Them?

Experts point out that a construction carried out with good technique, well calculated, and dimensioned should not present this type of problem. Thus, cracks can be considered a type of problem that must be foreseen by the engineer while still designing and executing the building. When a project is developed, account must be taken of the soil, the neighborhood, the trepidation of the street by the circulation of vehicles, the possibility of having new works in the vicinity, and especially respecting the time interval for making and curing all the elements of the building. Construction.

Keep An Eye On Your Home.

When observing the appearance of cracks, it is recommended to observe and carefully monitor their evolution. It is also essential to request a technician visit. Some information may be essential for the diagnosis of the problem:

  • Try to identify when the crack appeared
  • Track your growth
  • Check whether the structure crackles
  • Observe if the crack opens and closes periodically

If there was any factor that may have triggered the appearance of cracks (like a new work in the neighborhood, for example).
