Types of Foundation Repair
If you spot cracks in your foundation, get them fixed as soon as possible. Waiting leads to more damage and costlier repairs.
Cracks in the exterior walls of your house are early signs of foundation problems. If the cracks are thin, they can be sealed with epoxy or polyurethane injection. Visit Website to learn more.
Steel piers are one of the most reliable types of pier foundation repair options. The process involves drilling a series of holes through the concrete slab foundation and then driving steel rods into the ground to a depth that can support the structure’s weight. The piers are then either connected to a hydraulic manifold or supported by the slab foundation itself. The entire process can take less time than traditional concrete pier installation, which saves construction costs and limits site disruption. Steel piers also tend to have better longevity and durability than concrete piers, as long as they are properly maintained.
Despite their reputation for reliability, there are some drawbacks to steel piers that homeowners should consider. For one, the metal may be susceptible to corrosion if not regularly coated with protective sealant. Additionally, the piers may not provide the same level of aesthetic customization as a concrete foundation, which can be problematic for homeowners with design preferences. Finally, the equipment necessary for installing a steel foundation pier is expensive to purchase and rent, which can increase project costs.
The piers themselves are highly durable, which means that they can hold up to the weight of a home and other structures for decades. This makes them a good choice for situations in which soil conditions are unstable, but the structural integrity of a building needs to be preserved. However, because the piers are installed beneath the surface, they can be exposed to moisture swelling, which can compromise their long-term structural stability.
Another benefit of steel piers is their ability to be driven through hard or frozen soil with minimal damage. This is an important feature for residential construction projects in which the property owners want to avoid tearing up the landscape or disrupting local traffic patterns. In addition, the installation of steel piers produces relatively little noise and vibration compared to concrete foundation construction.
While many companies in the foundation repair industry offer a variety of solutions, some focus on steel piers as their primary solution for homes. The most prominent providers of these services emphasize the use of push piers, a specific type of steel pier, in their foundation repair. This type of pier is distinct from other types such as bracketed or helical piers because it is designed to be concentrically loaded, meaning that the entire weight of the house rests on a single pier.
Concrete Pile
Pile foundation repair involves the transfer of a building’s load to stronger soil or bedrock. They are particularly useful when the upper layer of soil is weak and cannot support the weight of a building. Pile foundations are usually made from concrete, although they can be made from steel and other materials. The installation process is quick and requires minimal equipment, so there’s less disruption to the surrounding landscape.
Concrete piles consist of vertical cylinders that are inserted into the ground. The installer digs a hole around the foundation where they want to insert the piles. Then, they use a hydraulic machine to push the cylinders deep into the ground. They continue pressing until they reach a certain point, called the point of refusal. This is when the crew should stop, because if they continue to push beyond this point, the cylinders will break and damage the house foundation.
While pressed piles offer a number of benefits, including being much more affordable than other foundation repair methods and requiring little space, they also have some disadvantages. For example, the cylinders used for this type of foundation repair tend to shift in different directions as they go through the soil, which can cause them to lose their load-bearing capacity. Moreover, they are not as strong as other types of piles and can crack or break easily.
Fortunately, there are several ways to mitigate these risks. For instance, the piles can be connected to a footing or a bearing plate that is attached to the bottom of the foundation. This can help increase the load-bearing capacity of the piers and prevent them from shifting. In addition, the piles can be capped with a concrete slab to further protect them from external forces.
Another way to enhance the stability of a pile foundation is to install a helical anchor. This is a galvanized steel pipe that is driven into the ground to a competent, load-bearing stratum. It is then attached to the pile with a remedial bracket to secure, stabilize, and lift the foundation. This type of solution is perfect for second-story homes or heavy structures.
Poured Concrete Piers
A variation of the steel pier is the concrete pier, made from precast 3000 PSI concrete blocks that are stacked side by side. They form a flat platform surface that is then placed under the foundation. A 20-ton bottle jack is then used to raise the house intermittently at all pier locations until the foundation reaches the optimal lifting point to restore functionality to the dwelling and alleviate the problematic symptoms of settlement. Once the home has been lifted to a satisfactory level, shims are then hammered between each block to ensure that the concrete is firmly in place.
Poured concrete piers have a long history of use under homes. The poured pier method is more expensive than slabjacking, and requires excavation around your foundation to dig a hole for each of the piers.
Like steel piers, concrete piers are susceptible to corrosion from acids in rain and minerals in soil. This corrosion can be mitigated by having the piers galvanized, which adds a protective layer of molten zinc to the metal to prevent damage from environmental factors.
Another option for a concrete pier is the helical pier. This is similar to the steel pier in that it uses segments of helix-shaped pipe to penetrate the earth and support the house, but it’s faster because there’s no need to manually mix and pour concrete into each pile hole.
A pressed concrete pier is a round, solid cylinder of reinforced concrete that’s inserted into a hole in the ground. It looks a lot like an empty toilet paper roll, and it’s typically made in a factory. It is often used in areas with poor bearing capacity, because it distributes the design load over a larger area.
Like the helix-shaped pier, a pressed concrete pier is installed in a similar way to a steel or concrete piling, except that instead of using segmented pipes, repair crews insert precast concrete cylinders into a hollow hole and use a hydraulic tool to press them into the ground. Like the other pier types, this technique can be used to lift and stabilize entire foundations, but it is also a good choice for small projects such as leveling patios, sidewalks, garage floors, and other nonstructural concrete slabs.
Pressure Grouting
Pressure grouting is a type of soil stabilization that uses cement-based grout material to fill void spaces and improve the structural integrity of foundations, footers, walls, and other structures. The process of pressure grouting involves injecting grout materials under high pressure to fill cavities and voids that are generally inaccessible to other means of repair. There are several types of grouting materials that can be used, including cement grout, chemical grout, and polyurethane foam. Our experts can help you decide which type of grouting will work best for your specific project.
The purpose of pressure grouting is to correct soil instability that has caused damage or a sinking foundation. It can also be used to reduce the rate of settlement and increase a structure’s structural support by reducing soil permeability. To perform a pressure grouting project, our team first inspects the site to determine strategic places to drill holes. Then, we use a pressurized pump to insert the grout. The grout will fill void spaces and strengthen the foundation, eliminate cracks, fix faults, and reduce water flow.
One of the biggest benefits of using a pressure grouting contractor is that it is a less invasive method than other repair methods. This is particularly true for areas where access to the ground is difficult or requires heavy machinery. Another advantage of this type of repair is that it is a quiet solution, so you will not have to worry about disruptions in your daily life while the job is taking place.
There are certain factors that can influence the outcome of a pressure grouting project, such as the quality of the materials used, the skills of the technician, and maintenance practices. Moisture management is particularly important to prevent the buildup of water pressure that could compromise the grouted area.
If you have noticed that your foundation is beginning to show signs of settling or cracking, it is vital to get the issue addressed as soon as possible.

The Importance of Concrete Repair
Charleston Chimney Repair involve a condition evaluation to determine the current state of the structure and its causes of deterioration or distress. Suitable repair methods and materials are then selected to achieve the desired results.
Surface prep, mixing the correct material, and curing conditions all impact the durability of repaired concrete. Contractors should follow manufacturers’ advice and connect with experts to ensure a successful repair.
Concrete is a strong and durable material, but it can still crack. When this happens, it is important to repair it immediately. This will help to prevent water and other contaminants from entering the structure and causing damage or posing a health risk. Several methods can be used to repair concrete cracks. One of the most common is routing and sealing. This involves using a router to cut a V-shaped groove along the length of the crack and then filling it with an appropriate sealant. This quick and cost-effective method can fix a wide range of cracks.
Other crack repair methods include drilling and plugging. This consists of drilling holes along the length of the crack and then filling them with grout or epoxy. This will create a “key” that locks the crack and reduces the movement of surrounding concrete sections. This relatively quick and cost-effective method can repair cracks in old and new concrete structures.
In some cases, injecting concrete into a crack may be necessary. This is often used in structural repairs but also for aesthetic purposes. When injecting concrete into a crack, it is important to ensure that the correct ratio of water and concrete is used. Too much water can lead to a loss of strength, while too little water will result in a shrinkage crack. In addition, it is essential to use a high-quality injection material.
Some cracks can be injected with polyurethane or epoxy materials. This type of injection can be very effective in repairing cracks in concrete, but it is important to consult a professional before doing so. These professionals can advise on the best materials to use and provide guidance on the proper injection technique.
If a concrete slab has a wide crack that runs across the entire surface, it may be necessary to repair it. This will prevent the crack from reoccurring and can help improve the structure’s appearance. Sometimes, this can even be done without removing the existing concrete.
Concrete is intended to last a long time; however, if left untreated, the surface can degrade, and damage may occur. This can lead to holes or cracks in the concrete, which can be dangerous for pedestrians and vehicles. By repairing concrete surfaces early on, you can prolong their lifespan and prevent future damage, saving money in the long run.
Concrete repair can also have environmental benefits as it helps to avoid the need for expensive replacements. Removing old concrete is costly and laborious; however, fixing minor damage like holes and cracks can reduce the need for removal, which helps keep costs down. Concrete repair also helps to reduce waste as it eliminates the need for demolition and disposal, which can be detrimental to the environment.
When repairing small holes in concrete, the best option is to use a patching compound available in many different forms. It is important to clean the hole of any loose debris and ensure it is flat and level before applying the patching compound. Once you have brushed on a bonding agent (which can be purchased in a kit), you can use the patching material to fill the hole.
For larger holes in concrete, it is a good idea to use a slab jacking technique, which involves drilling several tiny holes into the damaged slab. Then, a foam is pumped into the holes, which lifts the slab back to its original position. This is much quicker, more affordable, and less invasive than removing the slab and pouring a new one.
Hiring a professional concrete repair contractor for required repairs is always a good idea. Not only will they have the necessary expertise and experience to complete the repair correctly, but they will also be able to advise you on preventative maintenance, which can help to keep your concrete in good condition for as long as possible. They will also have the proper equipment and high-quality materials to ensure your repairs are done properly.
A concrete slab is a rebar-enforced structural component built onsite using a form-work boxing mold. Concrete slabs are often used for floors and ceilings between support beams, girders, or columns. They are also used for outdoor paving. Regardless of what type of use they are put to, slabs are vulnerable to damage from earthquakes and soil movement. As such, they need to be checked regularly for cracks and damage. The earlier they are repaired, the less likely they will need replacement.
Concrete slab cracking or sinking is often a normal part of aging. However, it is important to err on the side of caution and consult an expert before dismissing any issue as normal. The good news is that many of these issues can be corrected with simple, permanent repair methods.
Slab cracks often occur when water erodes the materials under a slab, causing it to sink. This can be caused by flooding; water flows through pipes or burrowing animals. Regardless of the cause, most slab cracks do not present significant structural problems and can be fixed superficially by patching when minor or epoxy injection when over 18″ wide or structural.
Even though the load-bearing capacity of a concrete slab is high, the heaviness of cars and trucks on a driveway or garage floor will eventually wear down the concrete until it cracks. This is especially true for unevenly distributed vehicle weight, as some parts of the slab are subjected to more pressure than others.
Unlike other concrete repair methods that involve demolition and pouring a new slab, airlift’s polyurethane foam lifting method (known as “polyjacking” or “concrete leveling”) allows us to raise sunken concrete without the cost and hassle of tearing down a structure. We use a polyurethane foam that expands underneath the slab, filling any voids that may have formed, raising the slab, and sealing the underside of the slab to prevent it from sinking again. This is a much quicker and more economical alternative to traditional concrete slab repair methods such as mudjacking or slab jacking.
Although many DIY enthusiasts enjoy taking on home improvement projects, certain repairs are best left to professional foundation repair contractors. These contractors will have a variety of methods at their disposal to fix a range of problems that can affect the strength and stability of a foundation. Depending on the issue, specific techniques can be used to ensure the solution will be long-lasting.
One common method is helical piling. This involves a series of concrete cylinders driven below a foundation until they reach soil with the necessary load-bearing capability. A contractor will drill these cylindrical holes and pour liquid concrete into them to lift and stabilize the foundation. This will also help to correct any sinking that may be occurring.
Another popular technique is epoxy injection. This is usually carried out after event damage and can effectively repair cracks. This is a great option for fixing a wide range of issues and will ensure that the cracks in a concrete foundation are fixed permanently.
Aside from being an excellent method of repairing structural damage to a foundation, this is a quick and affordable approach to concrete repair. This is because it doesn’t require removing and installing new concrete.
In addition to these techniques, professionals can use several other solutions to fix various problems. These solutions can combine several approaches or be used for more complex issues.
Most importantly, the correct foundation repair method is chosen for each unique situation. Using the wrong method can lead to further damage and even more costly repairs.
If a crack in your foundation is 1/8 to 1/4 inch, it’s not a serious problem and doesn’t pose any structural risks. However, it’s a good idea to seal these cracks to keep out moisture, soil smells, and radon gas. If the cracks in your foundation are wider than this, you’ll need to hire a professional for concrete repair.
