Pros Foundation Repair Greensboro NC is designed to fix conditions that cause damage. It’s often a more cost-effective and less invasive option than replacing your home’s foundation.
Symptoms of foundation problems include cracking walls and doors and windows that don’t open easily. Cracks wider than 1/4 inch can indicate serious issues that need to be addressed quickly.
Concrete piers are a popular and trusted method of foundation repair. They transfer the weight of a building from the structure to more stable soil layers or bedrock, unlike footings which spread the load horizontally. When a concrete foundation shifts or settles, it can cause visible cracks in walls and floors, doors and windows that won’t open or close, and uneven or sloping floors. Depending on the extent of the damage, a shifting foundation can be costly and disrupt daily life.
Piers can be installed in a few different ways. One method involves pouring a new foundation underneath the existing concrete, but this can be incredibly expensive and can take weeks to complete. Alternatively, concrete piers can be installed beneath the existing footing using hydraulic machinery. A concrete pier is a precast cylinder made of concrete that is driven into the ground. Hydraulic jacks are then used to lift the foundation back to its original position.
Another option is to use steel piers, which are more suitable for deeper soils than concrete ones. Unlike concrete piers, which can be damaged by water, steel piers are less affected by moisture. However, this solution is not recommended for homes with a basement because it can create problems with the waterproofing of the basement.
Regardless of which type of pier you choose, make sure to hire a professional with experience in pier installation. Ask for referrals from past clients and check their reputation. Make sure the professionals have insurance coverage, including worker’s compensation and liability, as this will protect you if something goes wrong during the process. They should also be members of reputable industry associations and have certifications. Additionally, make sure the company offers a written warranty. This will give you peace of mind that the repairs will be performed to a high standard and will last for years to come. A foundation repair company should also offer to install a drainage system, which will help keep the soil around your foundation dry and prevent water from seeping into the piers and damaging them.
Steel Piers
Steel piers, a cornerstone of modern foundation repair, are structural saviors that stabilize and strengthen settling or shifting homes and commercial buildings. They are typically used when the soil beneath a building is unstable, as they can be installed far into the ground to reach load-bearing bedrock. This gives them a superior load-bearing capacity over concrete piers, which may degrade or shift over time. Additionally, they have high resistance to environmental factors, such as moisture or changes in soil composition.
A popular choice among our Dallas-Fort Worth clients, steel piers are ideal for properties with a slab or pier and beam foundation that’s been damaged by shifting or sinking. In many cases, signs of this damage include widening cracks in walls and floors or doors and windows that are sticking or jamming when opened or closed.
To prepare the site for a steel pier installation, our team typically clears the area and excavates a hole directly beneath the foundation footing bottom. This allows the crew to properly position each steel pier, which is also known as a piling. Then, using specialized hydraulic equipment, the crew drives each steel pier into the ground until it reaches stable soil or bedrock. Once the piers are in place, they are connected to the foundation, which transfers the structure’s weight to them.
In addition to their impressive strength and stability, steel piers are also known for being cost-effective, durable, long-lasting, and environmentally friendly. They’re also an excellent choice for repairing residential and commercial buildings, as they can be installed with minimal disruption to the property.
During the installation process, our expert team ensures that each pier is properly aligned and secured with a cap to prevent water or other contaminants from seeping into the foundation. Once the piers are installed, our team performs load testing to verify that they’re capable of supporting the foundation’s weight. This is an important step, as it helps to ensure that the piers are capable of stabilizing and supporting your home or commercial building’s foundation for years to come.
Tieback Anchors
Helical tieback anchors are designed to stabilize foundation walls or retaining walls by transfering loads deep into the soil. They are especially useful for sloped or unstable sites, and they can also be used to reinforce existing retaining walls to prevent future collapse of the wall. However, like any other building structure they can be subject to failure from a variety of factors including groundwater intrusion, soil movement, and general wear and tear. In these instances, it is important to address leaks in tieback anchors quickly and effectively.
One of the most common issues affecting foundation walls is bowing. This occurs when the pressure exerted on the foundation by expansive soils or hydrostatic water pushes against the basement walls beyond their structural capacity. This can be a dangerous situation for homeowners, so it is critical to contact a foundation repair company as soon as you notice that your basement walls are bowing.
Professionals can correct a bowing basement wall by installing helical tieback anchors. These are long rods that work like corkscrews to straighten a bowing foundation wall by applying constant force. They are installed from inside the basement and require minimal excavation, making them ideal for properties with limited outside space. Additionally, helical tieback anchors can be loaded and tested immediately after installation to ensure that they will hold up to the load they are intended to carry.
When a helical tieback anchor is leaking, it is important to address the issue promptly in order to prevent further damage to your home or business. In these cases, it is recommended to use chemical grouting solutions that are effective at sealing leaks in tieback anchors. One such product is SealBoss 1510 Water Stop Foam, a high-performance polyurethane that expands rapidly upon contact with water to fill cracks and voids and create a strong, durable seal. This product is available through professional concrete contractors and engineers.
Another option for addressing leaks in helical tieback anchors is to install a mechanical grout system. These products are designed to penetrate deeper into the soil than traditional hydraulic grouts, allowing them to effectively fill the voids created by cracking and shifting of the surrounding soil. These systems are typically injected through small holes that are made in the concrete surface, and they can be loaded and tested right after installation to ensure that they will hold up against the loads they are intended to bear.
Soil Stabilization
Before any foundation or concrete structure is put in place, the soil it’s sitting on needs to be stabilized. This process helps prevent erosion and other environmental hazards, such as contamination of groundwater.
Soil stabilization is a vital step that all contractors must take for construction projects of any size, including homes, commercial buildings and even roads. If the subgrade is not stabilized, these projects are at risk of becoming structurally deficient over time. Stabilization techniques include chemical, mechanical or biological methods.
The first step in determining what method of stabilization will be best is conducting comprehensive soil testing. This allows us to see exactly what the soil is made of, how much moisture it contains and other important characteristics that will affect the project’s success. Then we can select the appropriate stabilizing agent based on this data.
Once the correct stabilizing agent is selected, it can be injected into the soil by spraying or pumping. Whether it’s an advanced ionic solution that reduces the expansive properties of clay soils, a cement mix with lime or fly ash, bitumen, tar, tree resin or something else entirely, this material changes the molecular makeup of the soil to improve its overall strength and durability.
Stabilized soils can provide a wide variety of benefits for construction and repair projects. This includes enhanced load-bearing capacity, reduced settlement and decreased susceptibility to changes in moisture levels. This can significantly reduce the need for costly foundation repairs and other structural damage.
It’s also worth mentioning that properly stabilizing the soil beneath your home will help protect it from flooding and stormwater damage, which are often caused by the same factors that can weaken the foundation itself. If you have an existing foundation that’s suffering from these issues, a professional contractor will be able to recommend the right solutions.
A professional can also advise you on the proper drainage options for your property to keep water away from the foundation and other problem areas. It’s important to choose a company with the right expertise, tools and equipment for both soil stabilization and foundation repair.
