Concrete Repair – What You Need to Know

A professional concrete repair contractor has the expertise and experience to assess the extent of damage and determine the best method of repairs. They can also guide preventative maintenance to help avoid future damage.

Moisture is a common problem that can degrade concrete structures. It can trickle into cracks and voids, weakening the bond with the concrete matrix. Proper curing can reduce moisture loss and promote the longevity of your repairs. Visit to learn more.Concrete Repair

Cracks in concrete should be repaired immediately, especially if they are wide enough to allow water to enter. This will keep the concrete from further deteriorating and will minimize the risk of structural damage to the structure. The first step in repairing concrete is to identify the factors that caused the cracking. This will help determine the type of repair needed and whether or not it is possible to successfully repair the concrete.

Once the cause is determined it is important to clean the cracks, removing all dirt and debris from the area. Using a pressure washer is recommended to ensure a clean surface for the repair material to adhere to. It is also helpful to remove any rust or paint from the concrete surface, especially if it is contaminated with oil or other solvents. In some cases a hammer can be used to chisel out any loose concrete in the crack. It is important to take good notes and photos at this point, and make sure the area is free of any contaminants. Upon completion of the cleaning process, a thin layer of bonding adhesive should be applied to the surface of the concrete.

Generally a latex or polyurethane product will be used to fill the cracks. Some products require a caulking gun while others can be mixed and troweled into the cracks with a putty knife, broad knife or trowel. Once the crack is filled, it should be sanded to smooth the finish and remove any air pockets in the concrete.

Wide cracks should be undercut against the sides of the crack to give it an inverted ‘V’ shape. This helps to promote a stronger mechanical bond between the concrete crack repair material and the existing concrete. It is also a good idea to use a concrete patching compound that contains fibers. This will give the patching material additional strength and flexibility.

Most concrete repair products will not resist the weather elements that caused the cracking, but it is important to look for a product that will at least hold up well in normal conditions. A product that has a high early strength may be desirable, but often the ingredients required to achieve this result can cause shrinkage cracking and shorten the service life of the repair.


Resurfacing is a process of applying a new surface over existing concrete, restoring its strength and appearance. It is ideal for driveways, sidewalks, patios, pool decks, and other outdoor concrete surfaces that have experienced a lot of wear and tear over time. Resurfacing is a cost-effective option when compared to breaking up the old concrete and pouring a new slab, plus it is faster and more environmentally friendly.

Prior to resurfacing, the concrete surface needs to be thoroughly cleaned. This can be done with a wire brush, broom, or power washer, and it is important that the entire concrete area is free from loose and crumbling concrete. Once the surface has been prepared, concrete patching material can be applied to fix any cracks or pits in the concrete. It is best to use a concrete patching product that has been designed specifically for concrete repair, such as Sakrete’s Top ‘n Bond, as these products have excellent adhesion and are formulated to bond well with concrete.

It is also important that the resurfacing concrete is thoroughly hydrated. This can be accomplished by spraying the surface with water before applying the resurfacing material. This will ensure that the new material adheres to the existing concrete properly and prevent any future problems, such as deterioration of the concrete or a loss of the surface finish.

A common mistake made by unexperienced contractors is over-wetting the resurfacing concrete. If too much water is added to the resurfacing concrete, it will lose its ability to adhere to the existing concrete and will begin to break down and peel away from the surface. It is also possible that the resurfacing material will begin to crack or chip if it is applied over an area of very poor concrete.

Resurfacing concrete is not suitable for structural repairs, but it can be used to repair minor cosmetic issues and extend the lifespan of the concrete. Using high-quality materials, professional installation, and routine maintenance can help to keep the resurfaced concrete in good condition for a long time. In addition, a contractor with experience in concrete resurfacing can offer helpful advice and recommendations for the care of the resurfaced concrete.

Structural Repairs

A major structural repair in concrete involves reinforcing steel or other structural materials being placed to strengthen a failing structure. This type of repair is generally carried out in conjunction with a complete condition evaluation of the structure to assess its current state and determine its causes of deterioration or distress. This is accomplished through a combination of visual inspection, destructive and nondestructive testing, review of design and construction documents, and laboratory results from chemical and petrographic analysis of concrete samples.

Once the cause of the damage is determined, it is time to start making repairs. Structural damage can be caused by a number of different factors such as corrosion, spalling, or cracking. The best way to repair a problem like this is to prevent it from happening in the first place. Concrete maintenance programs can help keep structures in good condition and reduce the need for costly repairs or replacements.

It is essential that any concrete repair work is done correctly to ensure a long lasting solution. Choosing the wrong type of repair for a particular problem can cause further damage to the structure and lead to a failed repair. The first step is to make sure that all unsound concrete and contamination is removed from the damaged area. This is followed by a thorough cleaning of the area to create a clean surface for application of the repair material.

The concrete used in a repair should be the same as the original, but it should contain less water. This will help to reduce shrinkage and improve the bond strength with the existing concrete. The new concrete should also be placed as thick as possible. This will help to limit the movement of the reinforcing bar once it is cured and will make it more resistant to cracking.

Once the concrete is mixed and placed, it should be thoroughly consolidated by hand or mechanically compacted. The final step is to skim coat the entire area with Sakrete Top ‘N Bond to smooth the finish and add a uniform appearance. Once this is done the area should be covered with plastic and misted regularly to keep it moist.

Repairing Leaks

Concrete is an extremely durable material that, like most things, shows signs of wear and tear over time. These signs are usually visible as cracks or areas of deterioration in the surface. When these problems are left untreated, they can lead to leaks that can be very destructive to the structure. This is why it is important to have these issues repaired as soon as possible.

One way to do this is to use polyjacking. This method is less expensive than replacement and can be performed in a fraction of the time. This is especially useful if you are looking to fix a large area of damage.

Another way to repair leaks in concrete is to use hydraulic grout. There are a variety of products available, including foams and quick-setting mortars. However, many contractors recommend using a product called Kryton’s Krystol Concrete Leak Sealer. This is a fast-setting, low-shrink, hydraulic cement that uses crystalline technology to react to water ingress and prevent it from passing through the crack.

This method is effective for repairing both active and inactive leaks. To begin the process, you should identify the source of the leak. This can be done by examining the concrete for water stains or damp spots. You can also check the plumbing system to see if any of the pipes have been damaged.

The next step is to clean the concrete and the surrounding area. Make sure to remove any weeds, roots, or other debris from the surface of the concrete. Once the area is clean, you can then prepare it for the hydraulic grout. To do this, you need to dig down to the level of the leaking water. You should then create a chase that is the same length as the cracked area. Then you can fill in the chase with the hydraulic grout.

If you have any questions or concerns about concrete repairs, it’s always best to hire a professional contractor. They have the experience and knowledge to complete the job quickly, efficiently, and safely. In addition, reputable contractors offer warranties and insurance coverage to provide you with peace of mind.
