2. Common Causes of Foundation Problems in Canada

• Soil Type and Moisture Content:

  • Impact: Different soils react to water differently:
    • Clay Soil: Expands and shrinks a lot, putting pressure on foundations.
    • Silt Soil: Bad at draining, holds water.
    • Sandy Soil: Stable but can wash away easily.

• Freeze-Thaw Cycles:

  • Weather Changes: Freezing and thawing make soil shift, affecting the foundation.

• Poor Drainage Systems:

  • Why It Happens: Bad water management erodes soil or puts pressure on walls.

• Tree Roots:

  • Influence: Roots from big trees can grow under foundations, causing cracks.

• Construction Quality:

  • Proper Techniques: Foundations built right last longer. Bad practices cause early problems.
