Concrete Foundation Cracks

How to Fix

Concrete Floor or Wall Cracks

Cracks in concrete floors or walls can range from harmless, due to natural settling, to indicators of significant foundation issues. Narrow cracks may allow water, termites, and pests into your home, while cracks over 1/16 inch often suggest structural damage.

Helitech Waterproofing & Foundation Repair offers free consultations to assess your foundation crack concerns, identifying whether a quick epoxy injection or a more extensive foundation repair is needed. With financing options available, Helitech ensures you receive the right solution for lasting foundation stability, giving you the peace of mind you deserve.

Cracks in concrete slabs:

Dormant Cracks v. Active Cracks

Not all foundation cracks are harmless—while some are benign, others signal serious structural issues that can jeopardize your home’s integrity. That’s why it’s essential to keep an eye on any wall cracks you spot—even small hairline cracks—to detect any changes, like L-shaped cracks growing into a stair-step pattern.

There are two types of cracks in concrete—dormant and active:

Dormant cracks that stay the same over time are typically harmless, while active cracks indicate foundation movement that may require attention. The crack’s shape often reveals its cause: stair-step cracks may signal uneven settling, which might require foundation stabilization using braces or helical piles, while minor vertical cracks from concrete curing can usually be treated with epoxy injections.

Dormant cracks remain stable, showing no significant changes in depth, size, or direction over time, making them less concerning, though they should still be monitored. Active cracks, however, indicate foundation movement and tend to grow in size or shift direction, which can be dangerous. Large stair-step or horizontal cracks doubling in size are serious warning signs.

Helitech offers free consultations to inspect any active foundation cracks, determine the root cause, and recommend repairs tailored to the severity of the damage. Don’t wait to fix your foundation! Call us today and let us heal your home.

Common Types of Concrete Cracks

Description: Cracks of any width or length that run left to right. 

Implication: Your foundation wall is at risk of failure. Most likely, the wall will need to be stabilized with helical piles to help prevent future cracking.

 

Description: Cracks of any width or length that run top to bottom.

Implication: Minor vertical cracks can be sealed with an epoxy injection for quick repair, while more severe vertical cracks require robust structural solutions to ensure lasting stability.

Description: Cracks in a wall with a stair-stepped pattern.

Implication: A shift in your foundation’s footing can lead to cracks, and the type of repair will depend on the crack’s severity.

Description: A web of small cracks in the concrete.

Implication: These are usually surface-level cracks, mostly cosmetic, but they should be checked for any growth or changes over time.

Description: Narrow, but deep, cracks

Implication: Due to the depth of hairline cracks, water damage is a concern.

Description: Deep surface cracks which follow the direction of the reinforcement bars (rebar)

Implication: Spalling cracks are usually caused by rebar corrosion due to the presence of excess water.

They were great, they got the whole thing done in one day and the next day it rained more than it has all year and no water in the basement thanks to the great work and perfect timing.

Aaron J.

I forgot to mention what a great job Brad and his crew did! Before they started any work, Brad went over everything that they were going to do and how they were going to do it which I really appreciated because then I knew we were all on the same page. They put up plastic during the jackhammering and suggested I turn off the A/C (I did have all the registers closed) so there was minimum dust that got up to the main level. They completed all the jackhammering by the afternoon of the first day, Tuesday. Throughout all three days (I couldn’t believe they completed the job in 3 days!) they were very professional and I sensed they took pride in what they were doing. I was so pleased, too, that they seeded and laid straw down where they dug and placed the drainage line from the sump pump. If every crew is like Brad and his workers, Helitech should be very proud of their employees. I would highly recommend Helitech to any of my family and friends.

And thank YOU, John, for your first assessment of my situation back in May and for keeping in touch especially the week prior to the scheduled work and immediately following the completed job. Helitech gets an A+ in my book because of its knowledgeable and caring employees.
