No homeowner wants to see cracks in their foundation. Foundation cracks will affect the value of your home. Fortunately, some cracks are not as severe as others. Foundation cracks occur in all shapes and sizes. Homeowners must know the difference between a minor crack and a foundation crack that could be a severe problem.
What Are Vertical Foundation Cracks on a Property?
Foundation settlement can cause several types of foundation cracks.
Vertical Foundation cracks are those that run up and down your foundation walls. These cracks are the least problematic, and you can repair these cracks quickly and easily.
Vertical cracks are typically smaller than ⅛ inch in width. Concrete shrinkage can cause these cracks in your basement walls, and you usually notice them towards the middle of the walls. You should cover cracks until you can repair them to prevent bugs and water leaks.
If you notice larger vertical cracks in different areas, it may be an indication that you need to contact a professional. You should get a foundation contractor to determine the cause of the damages.
Horizontal foundation cracks are more severe and are often caused by hydrostatic water pressure against your foundation wall. You will often find horizontal cracks in a block foundation, and a frost heave will contribute to unbalanced pressure against your foundation walls.
Stair step cracks are common in block foundations. You will find these cracks along the mortar joints, which are generally caused by foundation settlement or shrinkage. These types of cracks can pose a severe threat to the structural integrity of your house. A call to your local foundation contractor is in order.
Hairline cracks are common in new construction, and you will notice these small cracks within a year as your new home’s foundation settles and dries. Repairing hairline cracks is an easy diy project for most homeowners, and you can cover most hairline cracks with a coat of paint.
Diagonal cracks do not cause structural problems, and they occur with the natural settling of the foundation. Owners can repair a diagonal wall crack with epoxy injection.
Shrinkage cracks occur as your foundation settles and loses moisture. New constructions are prone to shrinkage cracks within the first year. Check your warranty because it may cover the crack repair.
A non-structural foundation crack is relatively common and does not threaten the house’s structure. Homeowners may find that rainwater and melted snow leak into the basement through these cracks.
Structural foundation cracks are the most serious. These are horizontal cracks and cracks that are wider than 1/4 inch. Movement of the house causes these cracks, and changes in temperature, soil pressure, and shrinkage can contribute to this movement.
These cracks will take more than an epoxy injection, and you need to install carbon fiber countersunk staples or straps for support.
Some cracks are more problematic than others. If you have any doubts, your best bet is to ask for a free inspection by a foundation expert, and they will provide you with a free quote detailing the foundation repair cost. Sometimes, the wisest route is to have a professional foundation contractor repair the damage, and most companies will warranty their repairs.
How To Identify Vertical Foundation Cracks
Vertical foundation cracks are standard, but it is essential to identify their cause and repair them.
You may see vertical cracks in masonry between two structures. This damage often happens due to differential settlement or thermal movement. Homeowners may see this when they add an extension to their home, which can be dangerous if not properly addressed.
There are also very straight vertical lines or wandering lines in poured concrete. These occur as the concrete shrinks and do not threaten your concrete foundation’s structural integrity.
Vertical foundation cracks that are straight and found near the end of the walls can be dangerous, and these cracks can lead to an eventual collapse.
You might also see vertical foundation cracks that are wider at the bottom. Foundation settlement due to a frost heave will cause these. These cracks are not serious unless you find them in a brick wall.
