Are cracks in basement walls normal?
It’s not uncommon to be in any basement and notice a few cracks here or there. Yes, they can be frustrating to the homeowner, but they’re a common occurrence. Stress points are one of the reasons cracks are created in your walls. They can occur when you’re installing lines for the electric, gas or sewer.
When should I fix a crack in my basement wall?
When you see basement wall cracks, you most likely want to fix them right away. You will especially want to do so if the cracks are large, or if they are horizontal, as that may be a sign of major structural damage.
How can I fix my cracked walls permanently?
Use a utility knife to cut a 1/8 inch to 1/4 inch V-notch along the length of the crack. Vacuum out loose material. Cover the crack with either mesh joint tape or joint compound and paper tape, followed by a thin layer of joint compound, extending about 2 inches on each side of the tape. Allow to dry.

Homeowners insurance will cover foundation repair if the cause of damage is covered in your policy. But damage caused by earthquakes, flooding, and the settling and cracking of your foundation over time are not covered.
Does Flex Seal work on basement walls?
Flex Shot and Flex Seal Liquid are great options for attacking a basement wall leak. Pour the Flex Seal Liquid into any larger cracks, then you can use a roller or brush to cover larger areas. Be sure to apply several coats and cover the area as much as you can. For best results, allow 24 hours for each coat to dry.

How do you know if a wall crack is serious?
The cracks are wide
A damaged wall would be considered severe when it’s 25 millimeters or wider (2.5 centimeters or one inch) as it could be a sign of structural damage, subsidence (the sudden sinking of a house and its foundations) or something else.
What is considered a bad foundation crack?
Foundation cracks that run sideways (horizontally) are the most serious type of crack to look out for, as they can signal serious damage to your home’s foundation and structural integrity.
How do you waterproof a cracked basement wall?
Polyurethane has become the overwhelmingly preferred material by basement waterproofing professionals because it remains flexible after it has cured, preventing the crack from re-opening that could be caused by minor foundation movement.
