What Causes Sloping Floors?

Sloping floors can happen when your foundation settles unevenly. It is often times one of many problems that will occur when your foundation settles.

Causes of Sloping Floors

Foundation settlement happens when there is downward, or sinking movement of a foundation from its original position within the soil. Soil movement can also be a culprit for foundation settlement. Soil can move, shift, or compact for a multitude of reasons including:

  • Poorly Compacted or Unstable Soil. If the soil beneath the home or structure is not correctly compacted prior to construction, foundation settlement can happen fairly quickly. Unstable soil beneath a structure makes way for erosion, expansion, and contraction of soil, all of which can be detrimental for foundations.
  • Change in Moisture Levels. When there is excess moisture in the soil surrounding a foundation, the soil will expand. Prolonged exposure to excess water will cause erosion, especially on hills and slopes. On the other hand, when there is a lack of moisture in the soil, it will contract and often crack. Large cracks under or surrounding a structure’s foundation are dangerous because it creates a gap that the foundation can sink or fall into.
  • Weak Bearing Soils. Some types of soil are not recommended for construction purposes, such as organic soil. Organic soil is high in peat content, and decaying organic matter. This type of soil is not structurally sound. Therefore if weak-bearing soils are present under your foundation, it can lead to a multitude of structural issues.

What to Look For:

  • Large Gaps. Check for any large gaps between the bottom of the wall and the floor. Large and uneven gaps in these areas are a tell-tale sign that your foundation has settled.
  • Uneven Floors. Check the levelness of your floors. Is one side of the room higher than the other?
  • Cracks. Look for any cracks in walls and floors. Any movement in concrete typically will cause cracking once there is enough pressure. Non-uniform or “spidering” cracks in walls or ceilings are a sign that something in your foundation has shifted.
