1. Cause of the Wall Crack
- Shrinkage: This is due to the concrete foundation of the basement drying too quickly, causing it to shrink and lead to hairline cracks in the wall.
- Settling: This usually occurs after a building’s construction. Once the house is complete, the soil beneath it gradually compresses under its weight. As the house presses down on the soil, it will settle into the ground. The movement of the building leads to cracks, which can grow larger as the building settles further.
- Movement: Shifts in the ground due to seismic activity can cause cracks to appear. The more frequent and intensive the seismic activity is, the larger and more plentiful the cracks may be.
