Understanding Wall Cracks

Are you concerned about cracks in your walls? Cracks can signify underlying issues with your property’s foundation. Addressing these cracks promptly is essential to prevent further damage and maintain your property’s structural integrity.

We specialise in repairing cracks in residential and commercial properties using advanced methods to ensure long-lasting results. Partnering with Alchatek, we utilise top-of-the-line structural foams that are stronger than crystalline bedrock.

Causes of Wall Cracks

Cracks in your walls can arise from several factors, including:

  • Foundation Movement: Changes in the ground beneath your property can lead to instability and cracks.
  • Soil Conditions: Different types of soil react differently to moisture, affecting the stability of your foundations.
  • Poor Drainage: Excess water from poor drainage systems can soften the soil, causing subsidence.
  • Tree Roots: Vegetation near your property can draw moisture from the soil, destabilising it.
  • Construction Issues: Poorly designed or inadequately constructed foundations can result in wall cracks.

Types of Wall Cracks

Identifying the type of wall crack is crucial for determining the appropriate repair method:

  • Step Cracking in Brickwork: These stair-step or zig-zag cracks indicate foundation subsidence or shifting ground pressure.
  • Horizontal Cracks: These cracks suggest localised ground movement, potentially impacting the entire structure.
  • Door Frame or Window Cracks: Often hairline cracks, they highlight foundation movement and loss of load-bearing capacity.

Cracked walls, ceilings, and sinking floors are often the result of compromised foundations. If you’re concerned about foundation cracks due to subsidence or settlement, the well-being of your entire property could be at risk.
