Cracking walls are a common issue for many homeowners and builders, but often these cracks are symptoms of a much deeper problem: foundation movement. While cracks might seem harmless at first, ignoring them can lead to costly repairs and even structural failures. So, how do you know when to take them seriously?

What Causes Foundation Movement?
Foundation movement occurs when the soil beneath a structure shifts, often due to changes in moisture levels, soil composition, or pressure. Here are the main culprits:
• Soil Expansion and Contraction: Clay soils, in particular, are prone to expanding when wet and contracting when dry. This repeated movement can cause your foundation to shift, resulting in cracks in walls and floors.
• Poor Drainage: If water is not effectively directed away from your home, it can saturate the soil, causing it to swell and put pressure on your foundation.
• Tree Roots: The roots of large trees near your home can absorb moisture from the soil, causing it to shrink and destabilise the foundation.
• Inadequate Footings: If the foundation wasn’t properly designed or built to accommodate local soil conditions, it can lead to uneven settlement over time.

Signs That Foundation Movement is Occurring
Recognising the signs of foundation movement early is key to preventing more serious damage. Here are some indicators:
• Diagonal Cracks in Walls: Cracks that appear at an angle, especially around windows and doors, are often a sign that the foundation is shifting.
• Uneven Floors: If your floors are sloping or feel uneven when you walk across them, it could be due to a sinking foundation.
• Doors and Windows Sticking: Difficulty opening or closing doors and windows can result from warping caused by foundation movement.

Why You Should Act Quickly
Ignoring signs of foundation movement can lead to more severe problems down the road, including structural instability, water infiltration, and even collapse in extreme cases. By addressing the issue early, you can save yourself from costly repairs later.
