What is the difference between subsidence and settlement?
Settlement usually occurs in new or relatively new buildings. They are very heavy and cause the ground to compact, but this normally stops after a short while. … Subsidence on the other hand is far more serious and occurs when the ground beneath the building is unable to support it.
What kind of foundation cracks are bad?
Of all the foundation cracks, the stair-step cracks are the most dangerous. They normally run in a diagonal line and assail concrete blocks and brick foundations. Cracks start in a joint or at the end of the wall then taper down or climb up. Like all diagonal cracks, they’re caused by differential settlement.
Do subsidence cracks look like?
The tell-tale sign of subsidence is a diagonal crack, next to a door or window, which is often narrow at the bottom and wider at the top. Look out for cracks that can be seen on both the inside and outside of the house. If they are underneath wallpaper, they may cause it to wrinkle.

Why do cracks occur on walls? Here are a few common reasons: Contraction and expansion: The materials (paint, plaster) that make up your wall contract and expand because of fluctuations in humidity levels and temperature changes. … In addition, using different paints for each paint coat can also cause cracks on the wall.
Do cracks in walls indicate a structural problem?
Hairline cracks over doors and windows are likely due to settling.

What do settlement cracks look like?

How long does it take for settlement cracks to stop?
This ‘settling’ process can take up to three years and is a normal part of the change in temperature, the drying out of the cement, plaster, bricks and so on,” explains Mbuso Mahlanga of Cosmopolitan Projects, national developers of affordable housing.
Are vertical or horizontal cracks worse?
The simple answer is yes. Vertical cracks are usually the direct result of foundation settling, and these are the more common of foundation issues. Horizontal cracks are generally caused by soil pressure and are normally worse than vertical cracks.
