Repairing Cracks with Epoxy & Polyurethane Injection


Cracks in foundation walls can unnerve even the savviest homeowners, as they cause immediate concern about foundation issues. However, not all cracked walls indicate a severe problem. The fact is — concrete cracks. Usually, wall cracks are common shrinkage cracks that occur as the concrete cures. These cracks are typically vertical and usually less than 1/16″ wide. They are quite different from structural or settlement cracks which can happen due to differential loading, lateral pressure, or from vertical movement due to soil shrinkage.


Regardless of which type you have, it’s important to find the cause of the crack, repair it properly, and prevent future cracks from forming. When necessary, we add a structural component to the crack repair by adding carbon fiber stitches. Stronger than steel, the staples will prevent the crack from reopening even if the wall begins to move again.


No matter how your wall became cracked, we can perform a quick and effective repair. Please contact Rapid Concrete Raise & Sprays today for a free estimate to get started!

Cracks in Foundation Wall Corners are a sign of trounle!

Often times concrete footers and wall corners crack because of increased pressure over time. When it was poured, the concrete itself was strong enough. But over time, the concrete weakens and the pressure increases. A Carbon Fiber-Kevlar wall brace will double the strength of your concrete and will not allow for future cracking. 

Sometimes cracks are caused by unstable soils. Stabilize it with foam now, it could save you $1000s in the future!

Unfortunately, many home builders do not use proper compaction techniques when building foundations. This can cause the soil to move and shift under the foundation over the first few years of its life. Sometimes it is necessary to inject polyurethane foam under the horizontal slab before repairing the cracks in either that slab or the adjacent wall slabs.

Sealing Concrete is essential in Colorado elements

It still amazes us how few people understand benefits of sealed concrete. When concrete gets wet, the water will absorb into the surface. The moisture sits inside the concrete and when freezing temperatures come, the moisture freezes and creates cracks in your concrete. Our sealing products create a waterproof membrane over the top of the concrete's surface, and our joint sealer resists anything from reaching the soil beneath the surface.

When proper drainage is not present, voids next to foundations walls create hydrostatic pressure!

If for whatever reason water is allowed to persist outside of foundation walls, voids are created on the outside of these walls. When water returns, those voids fill with water, and put extra pressure on those foundation walls. In order to fill those voids properly, we can inject polyurethane foam through the walls the same way we do to lift flat concrete.

Common Questions

  • Why does concrete crack?

    Concrete is a popular building material that is known for its durability and strength. However, even the strongest concrete can crack over time. Understanding why concrete cracks is important for homeowners and business owners alike, as it can help prevent costly repairs and ensure the longevity of their concrete structures.

    There are several reasons why concrete may crack, including:

    1. Shrinkage

    One of the most common reasons for concrete cracking is shrinkage. As concrete dries and cures, it can shrink slightly, which can cause cracks to form. This type of cracking is often referred to as "drying shrinkage" and typically occurs within the first few weeks after the concrete has been poured.

    2. Settlement

    Another common cause of concrete cracking is settlement. When soil beneath a concrete slab shifts or compresses, it can cause the slab to settle unevenly. This can lead to stress on the concrete, which can result in cracking.

    3. Overloading

    Concrete is designed to withstand a certain amount of weight and pressure. If too much weight or pressure is placed on a slab of concrete, it can crack under the strain.

    4. Freezing and Thawing

    In colder climates, water can seep into small cracks in concrete and freeze during the winter months. As water freezes, it expands, which can cause small cracks to widen and become more pronounced over time.

    At Rapid, we specialize in polyurethane concrete lifting and crack stitch concrete crack repair services that are designed to address these issues head-on. Our team of experts uses state-of-the-art techniques and materials to lift settled slabs back into place and repair cracks before they become larger problems.

    By understanding why your concrete may be cracking in the first place, you can take steps to prevent further damage from occurring down the road. And if you do need professional help with your cracked or settled concrete, know that Rapid Raise & Sprays has got you covered!


  • What are my options for repairing a concrete crack?

    Depending on the severity, it may be possible that you need to remove and replace the concrete. However, if you would like to save over half the cost of replacement, first look into a carbon fiber repair system or polyjacking. 

  • What is the best way to prevent future cracking?

    The best way to prevent future cracking of concrete is to keep the concrete well-maintained and regularly sealed. This will help protect the concrete from damage caused by moisture, temperature fluctuations, and other environmental factors. Additionally, look out for any signs of possible stress when checking your concrete and act quickly if a crack is noticed. Check out our joint and hydrophobic sealers if you want maximum life out of your concrete. 

  • Are there different types of sealers I should use on my concrete?

    Yes - different sealers suit different uses depending on what kind of protection you need for your concrete. For instance, some sealers are ideal for outdoor use while others are better suited for indoor applications. It’s important to understand which type of sealer would work best in each situation for optimal performance and protection. We offer a full line of sealing products that are reasonably priced and are what we believe to be the best on the market, and we've done our research.

  • How do I know if I need to repair a concrete crack?

    If you notice a crack that is more than 1/4 inch wide, it’s likely time to repair it. Also, any cracks that appear to be getting bigger should also be repaired.

  • How long will repairs last?

    The longevity of your repair depends largely on how well it was done and how much strain is placed on the repaired area over time. Generally speaking, repairs can last anywhere from several years to decades, depending on the extent of damage and care taken during the repair process.Generally, we can extend the life of existing concrete by double or triple what it would have lasted if it goes untouched. 

  • Is it possible to repair large cracks?

    Yes, but it typically requires professional intervention due to the complexity of the repair process. With professional help, you can use a variety of methods such as foam injections or structural repairs depending on the size and severity of the crack.Call us today to schedule a free inspection and estimate. 

  • How do I know when I should reseal my concrete?

    Generally speaking, you should reseal your concrete every three to five years depending on the conditions it’s exposed to (e.g., weather). If you notice that your sealant is starting to wear off before this recommended time period or if water begins seeping through cracks or into small holes in your surface, then it may be time to reapply a new coat of sealer. We generally use a 10% per year degrading scale.
