Can a cracked concrete slab be repaired?
Oftentimes cracks in slabs are repaired by epoxy injection or filling the surface of the crack, and while that may appear to fix the problem, these repairs usually fail and result in call-backs or further problems.
Should you fix hairline cracks in concrete?
Broken Rule One: Hairline cracks are not worth the trouble fixing. Did you know that just about every crack in concrete started out as a hairline crack? Some so fine, you can not even see them with the naked eye. Cracking naturally occurs in concrete slabs as the concrete cures and shrinks.
Does Flex Seal work on concrete cracks?
Flex Seal can be used on almost every surface: wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, porcelain, drywall, rubber, cement, and vinyl. Plus, it won’t sag or drip in the summer heat, and it won’t crack or peel in the winter cold. It even prevents corrosion.

Is cracking in concrete normal?
When you see a crack in your concrete slab or wall, your first assumption is typically that something has been done wrong–but that’s not always the case. Actually, concrete cracks are very common, some are even inevitable.
Is a cracked slab a big deal?
A crack in a slab of 1/8 inch or less is typically a normal shrinkage crack and not a cause for concern. If the crack is larger or growing larger (an “active” crack), or one side of the crack is higher than the other, then you may need to have the work reviewed by a structural engineer.
How much does it cost to fix a cracked slab?
Average foundation repair cost for homeowners is typically just over $4000, or between $1800 and $6500. Minor patching of small cracks is often as low as $500, whereas major structural repairs or underpinning might cost over $10,000.
How do you repair hairline cracks in concrete foundation?
Thin hairline cracks can usually be repaired with a vinyl concrete patching compound. If recommended by the manufacturer, apply a concrete bonding adhesive or primer/additive to create the best bond possible between the old surface and the patching material.
Why is my fresh concrete cracking?
Probably the single most common reason for early cracks in concrete is plastic shrinkage. When the concrete is still in its plastic state (before hardening), it is full of water. This water takes up space and makes the slab a certain size. As the slab loses moisture while curing it gets a bit smaller.
