When concrete cracks or surface wear occurs, a simple repair can stop the problem from getting worse. But the right approach is critical.
Before a repair is attempted the existing concrete must be thoroughly cleaned. This is to ensure that all dust, dirt, oils and other contaminants are removed. For professional help, contact Concrete Repair Bismarck.
Concrete surfaces should also be profiled to increase their mechanical bond with the repair material. This increases both the strength and durability of the repairs.
Cracks are a normal part of the aging process, but they can lead to tripping hazards for people who walk on or around them. They can also let water, oxygen, and minerals enter the concrete and cause corrosion and deterioration. If you notice a crack in your concrete, it is important to have it repaired as soon as possible.
The question of how wide a crack must be before it becomes an issue is a complex one that can vary from person to person, and even from project to project. It depends on the location of the crack, its stability, and whether it is growing or getting wider. If you are concerned, it is best to consult with an engineer or concrete repair professional to determine the cause and recommend a suitable concrete crack repair technique.
Hairline cracks in concrete typically aren’t a concern, but they can allow ground water to leak into buildings or structures, causing structural damage. Cracks that are wider than a credit card, or that extend through the entire depth of the concrete, may be structural in nature and should be examined by a concrete repair expert.
If the concrete has become chipped and crumbling, it is likely beyond repair and will need to be replaced. It is better to have the work done now than risk someone falling and hurting themselves in the future.
Having a concrete surface that looks clean and undamaged helps to maintain the value of your home. It also gives a positive impression of your business or organization.
Concrete rendering can be used to cover up damaged or ugly concrete surfaces and give them a fresh, new appearance. This can help to protect the underlying concrete from further damage, as well as improve its durability and longevity.
Concrete repair requires careful planning, thorough inspection, and proper execution to ensure a quality result that will last. Skipping steps, using the wrong products or techniques, or not allowing sufficient time for the repair to cure, can lead to recurring problems and costly repairs down the road. Working with a reputable concrete repair contractor ensures that the right solutions are implemented to get your concrete back to its original condition and beauty.
Chips
When a concrete surface begins to deteriorate, the results can be more than just unsightly – they can impact the safety of those who use the space. Depending on the severity, it may be necessary to replace the damaged area altogether. However, for minor issues like cracks and chips, a concrete repair might be more suitable.
If your concrete has chips, you’ll want to use a high-quality cement patcher or concrete adhesive to make the repair. The best products will be able to bond with the surrounding concrete and create a visually uniform finish. They’ll also be able to stand up to abrasion and freeze-thaw cycles, as well as chemical attack.
You’ll need to thoroughly clean the damaged area before proceeding with any repairs. A wire brush or stiff-bristle brush can help you get rid of any loose dirt and debris. You’ll also want to ensure the damaged area is completely dry before moving forward with your project.
Once the cleaned area is ready, you can begin working on the concrete repair. It’s important to follow the manufacturer’s instructions carefully when using any concrete repair product, as incorrect application could cause the material to fail. You’ll also want to consider the material’s constructionability, which includes things like pumpability, slump, flow and hang / stickiness. This can have an impact on the time and labor required to install a specific type of repair.
For example, if you’re working on a large parking deck repair, a product with a high slurry viscosity will help reduce the amount of water needed to mix the materials. This can reduce the amount of time and energy required to complete a project, as well as increase the overall performance of the material.
Finally, you’ll need to decide if you’re going to use ready-mix concrete from a local concrete plant or site batched concrete for your repairs. Each type of concrete repair has its own advantages and disadvantages, so it’s worth discussing the options with a professional before choosing which one is right for your situation.
Sunken Areas
Sunken concrete surfaces don’t just affect curb appeal, they can also create trip hazards and expose your home to additional water damage. Although replacing concrete may seem like the only option, repairing sunken concrete is a far better choice.
The soil underneath a slab is constantly shifting, thanks to factors like moisture, temperature changes, tree root growth, and construction work. Those forces can weaken the concrete and cause it to sink or crack. The longer you leave it untreated, the worse the issue becomes, resulting in more cracking, further soil settlement, and eventual sinking of the concrete slab.
A professional can recommend the best course of action for fixing your sunken concrete. There are three main options: concrete replacement, mudjacking, and polyurethane foam concrete lifting. Concrete replacement and mudjacking both involve drilling holes into the affected slab and then pumping a material under the slab to lift it up. This material could be sand, cement, or gravel. The downside to these methods is that they don’t address the root cause of the problem. They’re also time consuming, expensive, and produce an uneven surface that can lead to future damage.
Unlike these methods, polyurethane foam concrete lifting is designed to stabilize the soil beneath a slab rather than just patching it. It’s faster, cheaper, and provides an attractive result. Plus, it doesn’t require a long curing period, which saves you money on energy bills.
Soil movement can be caused by a variety of factors, including erosion from rain or groundwater and poor drainage. A poorly graded yard can lead to water seepage along the edges of the concrete, which over time erodes and washes away the soil underneath the slab. It can also be caused by downspouts that direct water directly under the concrete or by over saturated, clay rich soils. Whatever the reason, fixing it quickly is important for preventing further issues and creating safe walkways around your home.

Structural Damage
Concrete structures are often subjected to heavy loads and vibrations, which can lead to structural damage. This can result in cracks, spalling or weakness. Structural damage in concrete must be repaired promptly to prevent further deterioration, reduce the risk of failure and minimize the cost of repairs. A professional engineer experienced in concrete construction should be consulted for the design of large-scale repair projects.
Identifying the cause of the damage is the first step in determining the best approach to repair. Surface damage is easy to spot, but identifying structural problems requires a thorough inspection by an expert. Different repair methods are appropriate for different types of damage, and it is important to use the right method for the specific problem.
Surface repairs, such as filling in cracks and chipping away loose concrete, can be effective for small areas of damaged concrete. However, for serious structural issues, replacement may be needed. Repairing and resurfacing are less invasive methods that target minor to moderate issues, while raising and replacing are typically reserved for situations when other repair options aren’t feasible or when aesthetics are a concern.
Freeze-thaw deterioration is common in many concrete surfaces, and proper repairs can help prevent the damage from worsening over time. Concrete is typically repaired by injecting epoxy resin into the damaged area, with or without added reinforcement.
In cases of major structural damage, it may be necessary to replace the affected section of concrete. This is a more extensive repair process that requires special equipment and skill, as well as careful preparation to ensure that the existing concrete is completely removed and replaced with high-quality concrete. Once the repairs are completed, the structure should be tested to ensure that it has been properly repaired. This can be done using a variety of methods, including acoustic sounding, x-ray, GPS imaging or ferro scanning. In addition, it is important to test the integrity of the repaired concrete after a period of time. This can be done using pull-off bonded coupon testing or other methods, according to ICRI and ASTM standards.
