Why Concrete Repair Is Important

Concrete repair requires a good understanding of what causes cracking and using products designed to address those issues. Most importantly, a repair must last.

Concrete Repair

Typical repair methods involve conventional placement of new concrete. This method works best on wide cracks. Contact Top Coat Technicians for professional help.

Another alternative is concrete stitching. This involves drilling entry and exit holes across the crack and securing them with metallic staples.

Cracks in concrete are a common problem that can occur due to many different factors. They range in size and severity, from hairline cracks that are barely noticeable to wide cracks that can compromise the structural integrity of a concrete slab. The severity and cause of a crack will determine the best repair methods.

Structural cracks that develop from faulty design, construction or overloading of concrete structures are the most serious and require immediate attention to ensure safety and durability. Non-structural cracks, on the other hand, are usually caused by internally induced stress in building materials and do not pose a significant risk to the structural integrity of the structure.

When a concrete slab is initially constructed, cracks will often form in the surface and surrounding areas as it hardens. These cracks are not necessarily a sign of a failure in the construction process, but may indicate that there is a problem with the sub-grade or the underlying soil. Typically, non-structural cracks can be repaired by applying an appropriate joint sealant to prevent water penetration and other damaging environmental contaminants.

The most effective method of repairing concrete cracks is by using a polyurethane resin injection. This is a high-pressure injection technique that is extremely effective in sealing wet and leaking cracks. The resin reacts with the water in the crack, chasing it away and expanding the crack to fill it up. This is a very strong and durable repair that will also help to stop any future water leaks. This type of crack repair is suitable for both dormant and active cracks.

Another option for repairing cracks in concrete is to use epoxy compounds or latex patching products. These products should be mixed according to the manufacturer’s instructions and applied to a clean crack in concrete. It is also important to clean the area around the crack to remove any dirt, mud, debris, moss or weeds that are growing in the crack.

Early thermal contraction cracks, which are caused by extreme temperature changes within a concrete structure or its immediate environment, can be repaired with a high-pressure polyurethane injection. The concrete is heated, then injected with the polyurethane resin to melt it into the concrete surface, creating a seal that will prevent future water penetration.


Concrete structures are subject to a wide range of environmental and in-service stresses that can lead to degradation. These stresses can be related to loading, movement, internal or external chemical attack or corrosion of reinforcement and may lead to cracking. The design of a structure must take into account these environmental stressors. During construction, the concrete must be poured properly to ensure that it is strong enough to carry loads, durable to resist weathering and long-term exposure to chemicals, and economical not only in terms of first cost but also in its ultimate service life.

The first step in a successful concrete repair should be an investigation to determine the cause of deterioration. This should include a thorough inspection of the structure, including the identification and recording of crack dispositions, patterns and intensities and their relationship to structural geometry, concreting sequence, localized detailing (especially where cracking may coincide with water leakage) and both environmental and in-service conditions.

Once the cause of deterioration has been identified, the next step is to develop an appropriate repair strategy. This should involve arresting the rate of deterioration and, where possible, protecting or reinforcing the exposed concrete. This may require the removal of existing concrete, either a full slab or just the sound section, which is then replaced using normal concrete placement techniques. It is important to note that the depth of replacement should not exceed 6 inches or the void could cause future problems.

A common mistake is to pour new concrete in the void of sunken concrete. This can cause a host of issues, from settling and spalling to premature concrete cracking. The best way to fix this is to remove the old concrete, correct the sub soil/base problem and then pour the concrete again.

Concrete repair can be very complex. It would be unrealistic to suggest that it will be possible to identify a single cause for each symptom detected during the evaluation of a structure. It is more likely that a combination of several mechanisms will be responsible. These might include corrosion of reinforcement, freeze-thaw action, carbonation, chemical alkali-silica reaction, frosting damage and sulfate attack.

Water Infiltration

Water infiltration is a common issue in concrete structures and can cause damage to the slab or foundation. It may be due to flooding, heavy rains, plumbing leaks or soil movement. This type of damage can weaken the concrete’s integrity and result in structural cracking. It is important to have this problem addressed immediately to prevent future issues such as mold, mildew, and structural damage.

Some of the signs that water infiltration has occurred in concrete include cracking and spalling. Spalling is when the surface of the concrete chips away and can be caused by a number of factors such as a high water table, hydrostatic pressure or normal shrinkage of poured concrete.

A professional contractor can assess the concrete structure and determine the appropriate repair method to prevent further damage. They will use the right tools and materials to ensure the repairs are done correctly and that they will last. Professional contractors also have the expertise to advise customers on preventative maintenance practices.

Often, hair cracks that appear in concrete walls and aren’t sealed will eventually lead to moisture infiltration. These cracks should be filled with cementitious waterproofing materials that will seal the crack and stop moisture from entering the structure. It is recommended to use a product that has good adhesion properties, can accommodate movement and be easily painted for an attractive finish.

If the cracks are larger and have formed a cavity, it may be necessary to fill these with concrete patching materials that will repair and level the concrete. This can be done by hand or with a power float depending on the size of the cavity. The cracks should then be cleaned and sanded down to prepare them for the patching material.

Although some cracks are minor and don’t affect the structure’s stability, it is still a good idea to have them repaired as soon as possible. Not only can this protect against structural damage, but it can prevent mold and mildew from growing, as well as keep soil gases such as radon out of homes and occupied spaces.


Keeping up with the windows, appliances, kitchen cabinets and siding on a house takes work, but don’t forget the concrete surfaces around your home. Trip hazards like out-of-level sidewalk slabs and steps are not only a nuisance, but could also lead to expensive lawsuits if someone is injured on your property.

Concrete repair requires careful inspection to determine the root cause of the problem. It’s vital to understand that cracking and deterioration are only the visible symptoms of the underlying problem. If the underlying cause of the problem is not addressed, it will continue to damage and degrade the concrete.

Maintenance is the best way to keep up with a concrete structure’s needs and extend its service life. This includes cleaning the surface, inspecting for signs of deterioration, and responding to any problems promptly.

In addition to extending the service life of the concrete, proper maintenance helps reduce environmental damage, which is an important aspect of sustainable construction. An increase in repair activities due to durability failure has a direct impact on the environment, depleting natural resources and producing massive amounts of waste.

Concrete structures are weakened by exposure to water, salt and other chemicals. These elements penetrate the concrete surface to reach the steel reinforcing, causing corrosion and internal damage that can eventually lead to failure. This type of damage is the most common reason for concrete repairs.

When repairing damaged concrete, it’s important to ensure that the new material is properly cured. Long moist-curing times are essential for achieving adequate strength and durability. Insufficient curing can weaken the bond between the new and old concrete, causing it to crack or become loose.

Whether you’re building a commercial or residential concrete project, there are some things that every contractor should know about maintaining the integrity of their structure. Avoid these common mistakes to get the most out of your concrete repair projects. This will save you time, money and prevent future problems down the road.


Masonry Repair

Brick and stone buildings can last a lifetime with proper maintenance. The key to longevity is recognizing and responding quickly to minor damage.

If you spot any masonry issues, contact us for a free assessment and estimate. We can recommend the right solution, whether it’s tuckpointing, parging, waterproof caulking or any other repair. For more information, visit this website at

Brick structures are susceptible to a variety of stressors. These can include weather variations that cause expansion and contraction, movement of building materials such as doors and windows, corrosion of steel or iron reinforcements and the movement of soils that impact foundations.

The result of these stressors is the development of mortar cracks in masonry walls, structures and sidewalks. While mortar cracks are a normal part of the process of deterioration, they should be addressed promptly to prevent further issues. If left unchecked, they can lead to the need for more extensive masonry restoration work.

To repair cracks in mortar, start by cold chiseling out the cracked material to a depth of an inch or less. Afterward, clean the crack and then mist the area to keep the new mortar from drying too quickly. Mix up a batch of fresh mortar and apply it to the crack using a masonry trowel, working in small sections so as not to overfill the crack. After it is filled, use a masonry jointing tool to mold the joints to a more uniform look.

Once the joints are finished, spray the area with water to keep it from drying too rapidly and then brush away any residual debris. If the crack continues to develop, consider mechanically stitching the masonry with a crack stitching system such as PowaTwist, which uses stainless steel bars with a special grout that locks everything in place. These types of systems can be much more effective than simply filling in the cracks with a simple patch, as they redistribute tensile loads throughout the structure.

It is always best to prevent these cracks from developing in the first place, as it can save you a lot of money and time in the long run. A general cleaning of your masonry surfaces and regular inspections can help to detect problems before they become too serious, as well as prevent the need for costly masonry repair. Water repellants are also an excellent way to prevent moisture from damaging masonry structures. While these products cannot stop all cracking and crumbling, they can significantly increase the life of a brick structure.

Repairing Damaged Units

Masonry is a material used to construct many buildings, structures and walls. It is a popular choice because of its durability, strength, fire resistance and sound-proofing. But like any material, masonry will eventually wear down and require repair. Periodic inspections should be conducted to assess the condition of a masonry building, and a masonry repair plan should be devised accordingly.

Masonry repairs can include everything from re-pointing to patching and repairing damaged brick units. Re-pointing involves replacing old mortar with new mortar of the same strength and composition as the original mortar. This is an essential part of masonry restoration, and it can help to keep the underlying brick, stone or concrete from being exposed to too much water.

The most common masonry repairs are to fix damage caused by impacts, such as cracks that are a result of movement or the impact from a car or other vehicle. Cracks can also be caused by the contraction and expansion of masonry due to changes in temperature or by the natural freeze-thaw cycle. In some cases, the masonry unit may be completely removed and replaced with an appropriate replacement.

Repairs to damaged masonry units should be made as close as possible in size and appearance to the existing unit. This will ensure that the repaired area is as functional and visually compatible as the rest of the masonry. In addition, any masonry repair should be as minimal as possible in order to preserve the historic integrity of the structure.

Masonry repairs should be carefully designed to preserve the structural and visual integrity of a historical or existing building. These repairs should not be confused with a building restoration, which is usually a larger and more involved project. Restoration projects typically involve restoring a building to its original appearance.

Historic masonry structures can be difficult to maintain and repair, but with proper care they can continue to serve their owner for generations. Regular masonry repairs and maintenance can extend the life of a masonry building significantly, and they can prevent the need for costly restorations. The best way to ensure that a historic masonry structure is properly cared for and protected is to have a thorough inspection done by qualified professionals.

Repairing Control Joints

Masonry is a common construction material, and many buildings are constructed of brick or stone. Some building use masonry as the primary structure, while others incorporate other materials such as wood or steel but have a masonry facade to add interest and beauty to the exterior. When a masonry structure experiences damage, it is important to hire a professional mason to repair the damaged areas and restore the structural integrity of the building.

Control joints are vertical weak planes intentionally built or cut into masonry to control where cracking occurs. They are typically required in concrete block masonry structures, but are recommended in any masonry system expected to experience net shrinkage, including precast concrete and cast stone.

When properly detailed and located, movement joints can help reduce the damaging effects of expansion, contraction, moisture related shrinkage, lateral forces and other structural stresses. The type, location and spacing of these joints depend on a variety of factors, including the masonry material, climatic conditions, size and shape of the building, and the experience and expertise of the contractor.

Most cracks in masonry walls are the result of failure to provide adequate design provisions for movement within the structure. Most of these structural failures occur at the interface of masonry veneers and window or door frames, where inadequate gaps between the frame and the masonry are created. These gaps provide a pathway for moisture to penetrate the wall, which is the leading cause of water penetration and freeze-thaw damage.

In order to minimize the occurrence of these cracks, designers are encouraged to illustrate and dimension gaps at the interface of the masonry veneers with window and door frames in their construction documents. These dimensions should be used to locate movement joints which, when properly detailed and located, can help prevent cracking of the masonry veneers at these openings.

To prevent moisture intrusion through these openings, a good quality caulk or joint sealant should be used. QUIKRETE Masonry Sealant is ideal for this purpose, as it has the proper formulation to accommodate expansion and contraction of masonry, while providing a long-lasting, weathertight seal. To properly install this product, it is first necessary to clean the surface of the joint by scrubbing it with a stiff bristle brush and scrub pad. Then, the gap should be backer rodd with a masonry jig and caulked with a high-strength, solvent-based polyurethane joint filler.

Repairing Damaged Stone

The stone surfaces of a wall should be repaired as soon as possible to prevent further damage and to ensure that the building has an attractive appearance. Small problems, such as cracked mortar or crumbling stone, can be dealt with quickly and inexpensively. More serious problems may require more extensive repair or even restoration by a commercial masonry contractor. Regular inspections by a masonry professional can help identify problem areas and prevent expensive and time-consuming repairs later on.

The first step in repairing stone masonry is to clean the damaged area of debris, dirt and loose mortar. Then, the cracks and gaps should be dampened with water to promote a good bond between the new repair material and the existing masonry. Depending on the size and location of the cracks or gaps, different types of repair materials will be used. For example, smaller gaps can be filled with a lime grout mix, while larger cracks or voids should be patched using a specialized stone epoxy or other product.

Once the cracks and gaps have been repaired, any damaged or missing stones should be replaced with similar stone. Before applying the replacement stone, it is important to find an appropriate stone that will match the existing texture and color of the wall. After the replacement stone has been carefully cut, it should be misted and then spread with a mason’s trowel over an area of the wall that is slightly larger than the cavity it will fill. It is also helpful to use a pointing tool to create grooves in the mortar for increased adhesion to the stone.

For more severe defects, sandblasting and dry pointing (injecting mortar into horizontal pores of a masonry surface) can be used to restore stone surfaces. However, these methods are not suitable for all exposures or for all stone types and should be limited to very sheltered walls. A more comprehensive approach to repairing stone masonry includes the use of a variety of repointing techniques, including traditional saddle joints that direct rainwater flowing onto cornices and other projecting elements away from perpendicular joints.

All You Need To Know About Concrete Services

Concrete is a ubiquitous building material. It makes up sidewalks and roads, and it’s even used in our homes. Concrete is also incredibly versatile. It can be colored and textured to make it look different than its usual dull light gray color.

Choosing the right concrete contractor is important for any home improvement project. Finding the right professional will save you time and money.

What is Concrete?

Concrete is one of the most widely used building materials on earth. It is strong, durable, fire resistant and simple to use. In fact, it is the backbone of most modern buildings and infrastructure including houses, schools, hospitals, airports, highways and rail systems. It is also the material of choice for many garden ornaments like water fountains, gnomes and statues as it can be molded to take on almost any form.

Generally, concrete is made of water, cement and aggregates (such as small stones, sand or crushed gravel). The ratio of these components can be adjusted to achieve different properties when the mixture hardens. This is called a design mix and the proportions of each ingredient are determined by the conditions the concrete will encounter, such as exposure to freezing temperatures or extra durability.

Once the cement, sand and gravel are mixed with water, it is poured into forms to create various shapes and sizes of structures. It may be poured by hand or by using chutes or buggies or it can be pumped or sprayed. Once the concrete is placed, it is vibrated or worked manually to ensure an even settlement into the forms and around any reinforcement. It is then left to cure, which typically takes a month or more.

Unlike steel or wood, which require coatings to protect them from weathering, concrete is naturally weather resistant. This means that it will not rust or decay over time and will keep its attractive appearance. Furthermore, concrete does not require regular painting or staining as these coatings can wear off over time. It is also a more environmentally friendly material than other building materials since it can be recycled and reused at the end of its life span. In addition, concrete can be molded into nearly any shape and is therefore more adaptable than other building materials. This makes it ideal for constructing curved walls and other structures that are difficult to build with other materials.

How to Find a Good Concrete Contractor

You should also ask about their pricing structure and why they charge what they do. Lastly, make sure to check that they have a valid license and insurance before hiring them.

Once you have chosen a concrete contractor, it is important to keep in contact with them throughout the process. This will ensure that any questions or concerns are addressed in a timely manner and that the project is completed on time. It is also a good idea to request a sample of their previous work, as this will give you an idea of the quality of their work. Finally, it is important to choose a contractor that provides you with a timeline for the project and will stick to it. This will ensure that the work is completed in a reasonable amount of time and that you are not overcharged for any materials or labor. In addition, it will also help you avoid any unexpected delays or setbacks. By following these tips, you can be sure to choose a concrete contractor that will meet all of your needs.

What Types of Concrete Are Available?

Concrete is one of the most versatile construction materials available, allowing it to be used for nearly any type of project. Its strength and durability make it a vital part of many airport runways, bridges, and roadways across the globe. However, it also has many residential and commercial uses. It is even an important ingredient in many different types of flooring and walls. There are many different types of concrete, and each type is used to suit specific construction needs.

Plain concrete is made from a basic mix of cement, aggregates, and sand. The essential constituents are mixed in a ratio of 1:2:4, which is known as the standard mix design. This type of concrete is typically used in construction of pavements and buildings where high tensile strength is not required. It can withstand compressive loads, but is not as durable against the stresses of vibrations and freezing temperatures.

Precast concrete is fabricated in a controlled environment and then delivered to the construction site. It is often used for structural walls, floors, and pavements because it allows for greater flexibility in size, shape, and thickness. It is also less susceptible to cracking, and it can be made with a variety of aggregates. However, it is expensive to transport and must be expertly installed.

Ready mix concrete is a mixture of water, cement, and aggregates that can be delivered to the construction site in either a truck or a batch plant. It can be mixed by hand or with a machine, and it can be customized to the needs of each project. This type of concrete is ideal for projects that require quick installation, as it can be mixed and placed within hours of delivery.

Air-entrained concrete is a type of concrete that contains small air bubbles in the mix. This reduces the amount of water in the concrete, making it lighter and more pliable. It is also more resistant to chemicals, abrasion, and freeze-thaw action than regular concrete.

Lightweight concrete is a type of precast concrete that contains a reduced quantity of coarse and fine aggregates and a higher proportion of lightweight admixtures. It is commonly produced using natural light aggregates such as clays, pumice, shale, and scoria, but it can be made with processed aggregates as well. This type of concrete has low thermal conductivity, making it more energy efficient than traditional concrete.

Why Should You Use Concrete?

Concrete is an extremely durable and affordable material that can be used for a variety of construction projects. It is highly sustainable because it is typically produced close to the site of a project using local materials. This reduces transportation costs and environmental impacts while boosting the local economy. Concrete is also one of the most energy-efficient building materials available. Its low permeability and thermal mass help to regulate temperatures, reducing heating and cooling costs.

Concrete can be easily molded to fit into any space or shape, making it a versatile choice for a wide range of construction applications. It can also be mixed with other ingredients to modify its properties or create specialty blends that meet unique needs. New types of concrete are being created every year, incorporating additives to change its color, surface texture, and other characteristics.

Compared to other building materials, concrete is non-combustible and fire-safe, making it resistant to heat, wind, water, rodents, and insects. It is also strong and durable, so it can withstand earthquakes and other natural disasters. This makes concrete an ideal building material for areas prone to seismic activity.

Another benefit of using concrete is that it can be poured in place or cast into a form. This eliminates the need for additional structural supports, which cuts down on construction costs and time. It is also non-porous, meaning it does not absorb moisture or stains. This makes it easy to clean and keeps it free from mold, mildew, and other contaminants.

In addition, concrete is a relatively inert material, so it does not promote the growth of bacteria and other pathogens. This is important in a health-conscious society, especially in the case of hospitals and other public buildings where sanitation is critical.

The fact that concrete is made from recycled and renewable resources is a huge selling point for environmentally conscious customers. The industry is constantly looking for ways to lower its carbon footprint and make concrete even more eco-friendly. This is achieved through a “whole-life performance” approach, where all impacts are taken into account—from raw materials extraction and manufacturing to construction and use of the building, to disposal or reuse at end-of-life.
