What Is Concrete Repair?

Concrete Repair is the process of repairing concrete surfaces or structures that have been damaged by wear and tear, weathering, or structural damage. It involves the use of several products and techniques.

Concrete repairs are often necessary due to aging and weathering, as well as heavy foot traffic and vehicle impact. Whether repair or replacement is the better option depends on the severity of damage and how it affects overall stability.

Concrete Repair

Concrete cracks are one of the most common repairs needed for concrete surfaces. These cracks can be caused by both structural and non-structural issues. Structural problems can mean that your structure is in danger of collapse while non-structural issues can be less serious but still need to be addressed. It is important to repair these cracks as soon as possible to prevent further damage and to keep moisture out of your structure.

When repairing a crack in concrete, the first step is to determine what type of crack you have. There are three different types of cracks in concrete – narrow, wide, and expanding. Once you know which type of crack you have, it can help you decide on the best course of action. Narrow cracks are typically less than 1/4-inch wide and can be repaired using a simple concrete patching compound. Wide cracks require a more involved repair process that includes filling the crack with foam backer rod and then applying a concrete patch. Expanding cracks are typically a sign of instability in the soil that is causing the slab to shift. In these cases, the crack will likely appear again unless the underlying issue is remedied.

The next step is to clean the area around the crack. This is important as any debris that is left in the crack can prevent the repair from working properly. Cleaning the crack with a pressure washer can help remove any dirt or sand that has accumulated in the crack. This will also help to ensure that the crack is free of any contaminants that may prevent the concrete patching compound from adhering to the concrete.

Once the surface is cleaned, it is time to prepare for the crack repair. The crack should be chiseled to create a backward-angled cut that will allow the concrete patching material to better adhere to the concrete. It is important that any loose gravel or debris is removed from the crack as well. Leaving this debris in the crack can cause it to come loose and fail in the future.

Repairing Spalling

Spalling is one of the most common issues affecting concrete, and it can be a big problem for homeowners. It happens when the surface of the concrete flakes or chips away, exposing the aggregate underneath. It can happen on driveways, patios, sidewalks, or even in basements and garage floors. The good news is, it’s easy to repair.

The first step in repairing spalling is to remove the loose concrete and any debris. This process may take some time, but it’s essential for ensuring the final results are high-quality and durable. After the concrete is removed, it’s important to clean and prepare the area for the new layer of repair material. This includes cleaning the rebar and removing any corrosion or other contaminants. It’s also a good idea to use a water sealant after the repairs are completed to protect the repaired surface.

There are several types of repair methods for spalling, and the best option will depend on the extent of the damage and the cause of the spalling. If the concrete is simply damaged and a little worn down, resurfacing may be sufficient to restore its appearance. This process involves applying a thin layer of concrete, effectively giving the concrete a brand new surface.

If the damage is more serious and the surface has become pitted and deformed, deep patching may be needed. This method requires removing the existing damaged concrete and patching the area with a special concrete product. It’s important to use a high-quality repair material that is compatible with the existing concrete, as incompatibilities can lead to premature failure.

While concrete repair and resurfacing activities have a significant impact on the environment and society, they can be made more eco-efficient. The design process must consider the full life-cycle of the repair system to ensure that it meets performance requirements and minimizes environmental impact and costs. This can be done by using a life-cycle cost analysis to determine the most cost-effective repair methods and materials. Additionally, it’s important to take safety precautions, allocate enough time for the project, consider professional help when necessary, and practice proper maintenance.

Repairing Leaks

If you notice water pooling or running down the sides of your concrete building, it’s probably a good idea to get it fixed as soon as possible. If you don’t, it could lead to substantial damage in the future, and even a foundation failure that requires major repair or replacement. A professional concrete restoration company will take care of this problem quickly and efficiently to avoid further damage.

Depending on the size of the leak, the first step is to use an electric chipping hammer to chip away all the old concrete around the crack. This will reveal the extent of the crack and the area to be filled. The next step is to make a chase for the leak and then clean out the existing concrete in the chase and prepare it for the injection product of choice.

There are several types of products available for repairing concrete leaks including injection grouts, mortars, and concretes. A key factor in a successful repair is the quality of the concrete substrate, its thickness, and moisture content. The quality of the concrete affects cement hydration and microstructure development, and the moisture content influences bond strength between repair materials and the concrete substrate.

It is also important that any repair concrete be properly cured. This is a step that is often shortened or performed haphazardly due to the desire to move on to other tasks on a project. However, it is an essential part of the repair process and if it isn’t done correctly, the performance of the repair will suffer.

The traditional patch repair of corroding areas triggers corrosion initiation in the adjacent passive areas as the local protection provided by the active anode area is removed. This is called the incipient anode effect.

Slab leaks can be caused by a number of things including faulty installation, the chemical reaction of metals in the water line to metal in the concrete, soil shifting beneath the slab, or even just natural aging. If a slab leak is left untreated, it can cause serious water damage to flooring, walls, furniture, and appliances. A slab leak can be repaired using polyjacking or concrete raising techniques, both of which are less expensive and time-consuming than replacing the slab.

Repairing Damaged Slabs

Concrete slabs are a critical aspect of your home’s structure. They are often used for weight bearing purposes and, like the rest of your home’s foundation, need to be well-maintained to ensure structural integrity. Cracks, spalling, discoloration and uneven slabs can all be signs of damage to a concrete slab that needs to be repaired.

Slab damage is often the result of a combination of factors including water, heavy equipment or traffic and is most likely caused by a weak point that allows movement within the slab. This weakness can be a hairline fracture, a concrete wash or even an area that is not post-tensioned.

A common repair method for slabs is to surface fill with epoxy. However, this is not a permanent solution because over time the crack will reopen and the patch can chip away. A better option is to install carbon fiber in the concrete slab to strengthen it and provide a permanent repair.

Before the repairs can begin the existing concrete must be prepared. This includes cleaning, de-greasing and making sure the slab is free of debris that could interfere with the bonding process. The repair materials must then be mixed and applied to the existing concrete. Once applied, the repair material is then allowed to cure. This step is important to the longevity of the repair and is often shortened, performed haphazardly or skipped altogether by less-experienced concrete repair contractors.

Once the repair has been completed, a concrete testing firm will be called to test the strength of the repaired slabs. This is to make sure that the slabs have reached their proper strength and can withstand the load that will be placed on them.

While repairing cracked or damaged concrete may seem expensive, it is much cheaper and faster than replacing the entire slab. Typically, replacement can take over a week to complete and there is a 28 day wait period before the new concrete can bear weight. Raising the concrete with poly foam, on the other hand, can be done in a few hours and is ready to use immediately afterward.
