What Is a Horizontal Foundation Crack and What Causes It?
A horizontal foundation crack refers to a crack that forms in a horizontal direction along the foundation wall of a building or structure. These cracks in foundations can be caused by various factors, including:
Soil Pressure
Excessive pressure from the surrounding soil can push against the foundation walls, causing them to crack horizontally.
Hydrostatic Pressure
When water accumulates around the foundation due to poor drainage or heavy rain, it can pressure the walls, leading to horizontal cracking.
Frost Heave
In colder climates, freezing and thawing cycles can cause the soil to expand and contract. This can result in pressure against the foundation, causing horizontal cracks.
Settling or Sinking
Uneven settling of the building’s foundation can create horizontal cracks as the structure shifts and adjusts over time.
Poor Construction
Inadequate reinforcement or structural flaws during construction can lead to horizontal cracking in the foundation walls.
How Severe Is a Horizontal Crack in a Foundation Wall, and When Will You Call a Professional
If you suspect any issues with your foundation, it’s always best to consult a qualified professional for an accurate assessment. However, here are some general considerations:
Size and Width
Horizontal cracks that are wider than about 1/8 inch (3 mm) or have a noticeable width increase should be taken more seriously than hairline cracks. Larger cracks can indicate more significant movement or structural issues.
While hairline cracks may not cause immediate concern, larger or widening cracks near crawl space foundation jacks should be evaluated by a professional to determine the underlying structural integrity and the potential need for repairs.
Length and Progression
If the crack extends for a considerable distance across the wall or has been observed growing over time, it may suggest an ongoing problem that requires professional attention.
Location
The location of the crack can also be significant. Cracks near corners, doorways, or windows are usually more concerning as they may indicate stress concentrations or foundation settlement.
Structural Impact
Observe any visible signs of structural damage, such as bowing or tilting of the wall, displacement of bricks or blocks, or any associated issues like water seepage or moisture problems. These signs may indicate a more severe problem requiring immediate professional intervention.
Expert Opinion
If you’re not sure what to do, it’s always best to ask an expert. Structural engineers or foundation experts are trained to look at cracks and make suggestions based on how bad they are. They can do a full inspection, run any necessary tests, and come up with good ways to fix any problems they find.
Time To Fix Those Horizontal Foundation Cracks
Horizontal foundation cracks are a sign that the foundation is settling, which could lead to further damage. Foundation specialists should be consulted for an inspection as soon as possible to identify the problem and create a plan to repair the damage. Early prevention can save significant time and money in foundation repair costs, so don’t hesitate to contact a local specialist today!
