Can Your Cracked Walls Be Repaired Or Is It Subsidence?

Your property might face a numerous number of problems due to the changes in weather and condition of the surrounding soil. If your house is nearby a busy road, the rumble of the passing traffic and vibrations produced below the ground can be one of the causes of disturbances in your house.

So, what exactly are these disturbances? Basically, disturbances are major or minor faults that arise in your home’s foundation and are visible superficially in walls or house as a whole.

In this article, we will talk more about how certain disturbances in your building’s foundation can lead to subsistence and what it is best possible way to deal with it.

Subsidence and Its Causes

If ignored, it can lead to some of the most potent problems. And so, it is necessary to identify if your house is subsidizing and if it needs proper corrective measures.

There are many causes of subsidence, some of them being:

Cracked Walls: Reasons and Repair

Cracks on walls arise due to several reasons. One such reason is subsidence as stated above.  Cracks are of different types such as:

  • Hairline cracks are of 0.1 mm and require no action
  • Fine cracks can be covered by simple decorations
  • Horizontal cracks including diagonal and stepped that generally arise in brickwork along mortar joints
  • Vertical cracks arise in internal walls

Cracks that have a width of more than 5 mm require treatment and should be fixed early so that they may not pose some major threat to the house. The reason for cracks can be any:

  • Subsidence: the most common cause of cracks in a house. Such cracks are diagonal and facing downwards.
  • Settlement: here cracks arise due to downward movement of property.
  • Heave: upwards movement of soil and cracks produced due to this are generally wider at the bottom.
  • Thermal movement: here cracks arise due to expansion and contraction of the construction materials.
  • Seasonal movements: every season has its own impact on the soil structure and shrinkage, cracks arising due to this may be worrying.

Other common reasons for wall cracks are:

  • Contraction and expansion: the paint and the plaster that make up the walls expand and contract due to fluctuations in weather, temperature and the humidity levels
  • Low paint quality: poor quality of paint may also lead to developing of cracks with time
  • Impatience: sometimes, when a wall is cemented without letting the cement dry on the walls can also lead to the development of cracks at later stages
  • Poor painting: painting is a job that has to be done with patience and doing it impenitently can lead to the development of cracks on the walls

Cracks with a width of less than 5mm and that arise due to construction, painting and weathering defects can be easily managed and fixed either by proofing them with a layer of cement and re-painting them. But, if the cracks have a width of more than 5mm and have appeared due to subsidence or settlement of building foundations, in such cases you have to call the contractors and get your house underpinned as soon as possible.
