What is post tensioned concrete?

Post-tensioned concrete is a type of reinforced concrete that uses high-strength steel cables or tendons under tension to compress the concrete and provide additional strength to the structure. The tendons are typically anchored at both ends, stretched and then anchored to the concrete using anchorage devices.

This results in a structure that is able to withstand greater stress, allowing for longer spans, thinner sections and reduced overall material usage. Post tensioned concrete is reinforced with steel cables or bars called tendons that are pulled and secured after, or ‘post,’ pouring of the concrete.

In some cases, post-tensioned slabs and beams are also ‘draped,’ meaning the tendons sag at the midpoint during installation and are then tensioned after the concrete is placed, achieving the highest tension possible on the cable. We often do post-tensioning in construction of high-rise buildings and car dealerships with large, open showrooms.

What are the benefits of post-tensioning?

Post-tensioning permits the construction of large open spaces in concrete structures and also permits slabs with a thinner profile. By eliminating interior supports and making suspended slabs lighter, you need less concrete, and the structure weighs less when complete.

The benefits of post-tensioning include:

Increased strength and stability
Post-tensioning enhances the strength and stability of concrete structures, allowing for longer spans, thinner sections, and reduced material usage.

Improved durability
The high-strength steel cables used in post-tensioning resist corrosion, providing long-term durability to the structure.

Reduced cracking
By applying compressive stress to the concrete, post-tensioning reduces the risk of cracking caused by tensile stress.

Increased versatility
Post-tensioning can be used in a variety of structures, including bridges, buildings, parking structures, and more.

Reduced construction time
Post-tensioning enables quicker construction times, as it eliminates the need for traditional reinforcing materials, such as steel bars.

Increased design flexibility
Post-tensioning allows for greater design flexibility, as it allows for longer spans, thinner sections, and more slender elements.

What is post tension repair and modification?

Post-tension repair and modification refers to the process of repairing and modifying existing post-tensioned concrete structures. This may be necessary due to a variety of reasons, such as damage to the concrete or steel tendons, changes in the load requirements of the structure, or design modifications.

The repair and modification process typically involves cutting the concrete to access the tendons, assessing the condition of the tendons, and then repairing or replacing any damaged components. In some cases, the post-tensioning system may also need to be adjusted or strengthened to meet new load requirements. The concrete is then repaired and the structure is restored to its original strength and stability.

Post-tension repair and modification requires specialized knowledge and equipment, as well as a thorough understanding of the existing post-tensioning system and the structure's load requirements. It is important to ensure that the repair and modification work is carried out by qualified professionals to ensure the safety and reliability of the structure.

Post-tension repair and modification are a specialty at our company. Our highly skilled crews are trained and equipped to repair and replace post tension tendons in existing buildings. Our crews can also do modifications on existing structures to inspect and re-purpose post-tensioned beams, slabs, and other concrete structures for building enlargements or repair.

What is barrier cable?

Barrier CablesBarrier cable is the name for a variety of special steel cables used for guardrails in open concrete structures like parking garages, outdoor walkways, and rooftop use areas. This wire is usually galvanized, making it rust-resistant and suitable for exposure to the elements.

Barrier cable is a type of cable used in post-tensioning systems for the construction of concrete structures, particularly for the construction of bridges and sound barriers.

Barrier cables are typically made of high-strength steel and are designed to resist the tension forces generated by the weight of the structure. They are installed within the concrete and are used to provide stability and prevent cracking by distributing the load evenly throughout the structure.

Barrier cables are typically anchored at both ends and run continuously along the length of the structure, providing a barrier against wind, water, and other external forces.

In barrier cable construction, heavy-duty anchors are set into pillars or walls and then connected to thick wire strands. Eight or more wires are placed about 6-inches apart to create a safe railing between the columns. In a barrier cable system in a parking garage, multiple wire cables span horizontally between the concrete posts where they anchor securely.

Barrier cables are an important component of post-tensioned concrete structures, as they help to enhance the structural integrity and stability of the structure, while also providing protection against environmental and other external factors.

If a person or vehicle hits the cables, the wires go into tension and resist the impact, preventing a catastrophic fall accident. Barrier cables also have the advantage of allowing plenty of sunlight and visibility into the interior of the parking structure.

What is 'form and pump' repair?

Form and pump repair is a method of repairing concrete structures, particularly those with post-tensioned cables. It is a process that involves the injection of a specially-formulated concrete mixture into cracks or voids in the structure using a pressure pumping system.

The first step in the form and pump repair process involves the creation of a form or a temporary casing around the damaged area. The form helps to contain the concrete mixture and ensures that it is distributed evenly throughout the damaged area.

Next, the concrete mixture is prepared and placed into a pressure pump. The mixture is then injected into the damaged area through small openings in the form, filling any cracks or voids. The pressure pump is used to control the flow of the mixture, ensuring that it is evenly distributed throughout the damaged area.

The form and pump repair method is effective for repairing concrete structures that are under tension, such as post-tensioned concrete bridges, buildings, and parking structures. It is a fast, efficient, and cost-effective method of repairing concrete structures that provides long-lasting results.

The form and pump repair method is often used in conjunction with other repair techniques, such as surface repair or surface sealing, to ensure a complete and thorough repair.

Air Pockets

In the form and pump repair method, it is important to ensure that no air pockets are trapped inside the injected repair material. Trapped air pockets can weaken the repair, causing it to fail over time, and potentially leading to further damage to the structure.

To avoid this, Strengthening Technologies uses specialized air vent tubes, which are strategically placed into the existing concrete. These tubes allow any air to escape during the injection process, ensuring that the repair material fills the damaged area completely and without any voids.

This step is crucial in ensuring the longevity of the repair. By removing air pockets, the repair material can bond effectively with the existing concrete, creating a strong and stable repair that will last for many years.

The form and pump repair method is a reliable and effective solution for repairing concrete structures, particularly post-tensioned concrete structures. With its focus on quality and safety, and the use of specialized techniques and equipment, Strengthening Technologies is well equipped to carry out this type of repair work, ensuring that your structure is safe and secure for years to come.

What is carbon fiber strengthening?

Carbon Fiber Reinforced Polymer (CFRP) is widely used in the concrete repair industry. It is lightweight with tremendous tensile strength, meaning it resists forces that try to pull it apart. 

Carbon fiber strengthening is a method of reinforcing concrete and masonry structures using carbon fiber composite materials. The process involves the bonding of thin, high-strength carbon fiber sheets to the surface of the concrete or masonry using a specially formulated adhesive. The carbon fiber sheets provide additional strength and stability to the structure, helping to prevent cracks and other forms of damage.

Carbon fiber strengthening is used to reinforce concrete and masonry structures that are showing signs of deterioration, such as cracking, spalling, and other forms of damage. It is also used to retrofit existing structures to meet current design standards and improve their overall performance.

One of the key benefits of carbon fiber strengthening is that it is non-invasive, meaning that it does not require the removal of any existing material. It can also be used in hard-to-reach areas, making it an ideal solution for structures with limited access.

Another advantage of carbon fiber strengthening is that it is lightweight, which means that it does not add significant additional weight to the structure. This makes it ideal for structures that are already at or near their weight-bearing capacity.

What is FRP (Fiber Reinforced Polymer) jacketing?

FRP (Fiber Reinforced Polymer) jacketing is a type of jacketing material that is used in the strengthening of concrete beams and columns. It is a composite material made up of a matrix (typically a polymer resin) and reinforcing fibers, which can be made from glass, carbon, or other materials. The fibers provide the necessary strength to the material, while the matrix binds the fibers together and protects them from damage.

The process of jacketing involves wrapping the FRP material around the concrete structure, effectively encasing it and providing additional strength and stability. The thickness of the FRP jacket depends on the specific requirements of the structure and the desired level of reinforcement. The material is easy to work with, as it can be molded and formed into various shapes and sizes to fit the structure being reinforced.

FRP jacketing is highly effective in increasing the structural capacity of concrete beams and columns, and is particularly useful in seismic strengthening projects, where additional resistance to earthquakes is required. The material is also lightweight, making it easy to transport and install, and has a high strength-to-weight ratio, making it an efficient solution for structural strengthening.

How is epoxy injection used for fixing concrete?

Epoxy injection is a method used to repair concrete structures by filling cracks and voids with a resin-based material. The epoxy is injected into the crack or void under pressure, ensuring that it penetrates deeply into the concrete and bonds to the surrounding material.

This method is useful for repairing cracks in concrete walls, floor slabs, bridges, and other structures, as it provides a strong and durable repair that can withstand heavy loads and harsh environmental conditions. The process of epoxy injection is performed by the experienced professionals at Strengthening Technologies, who use specialized equipment to carefully clean, prepare, and inject the epoxy into the damaged area.

Epoxy injection has several benefits when used for fixing concrete, including:

Epoxy is a very strong material, which makes it ideal for repairing cracks in concrete. The bond between the epoxy and the concrete is very strong, which helps to restore the structural integrity of the concrete.

Epoxy is a highly durable material, and the repair made using epoxy injection is designed to last for many years.

Ease of use
Epoxy injection is a relatively straightforward process that does not require extensive training or special equipment. This makes it a cost-effective solution for repairing cracks in concrete.

Epoxy injection can be used to repair cracks of various sizes, from hairline cracks to large cracks that measure several inches in width.

The repaired crack will be nearly invisible once the epoxy has cured, which can improve the overall appearance of the concrete.

Compared to other concrete repair methods, epoxy injection is often a more cost-effective solution, especially for smaller cracks.

What is Liquid Concrete Repair (LCR)?

Liquid Concrete Repair (LCR) is a type of repair method that uses a liquid product to repair cracks and other surface damage in concrete. The liquid product used by Strengthening Technologies is a polymer-based material that is applied to the surface of the concrete and then left to cure.

This method is commonly used for repairing small to medium-sized cracks and surface damage in concrete structures, such as sidewalks, driveways, and patios. It can also be used to repair surface damage caused by freeze-thaw cycles, salt scaling, and other environmental factors.

Some benefits of using Liquid Concrete Repair include:

Ease of application
Liquid Concrete Repair is easy to apply, and does not require special tools or equipment.

Fast curing time
Liquid Concrete Repair typically cures quickly, which means that the repaired area can be used again soon after the repair is complete.

Liquid Concrete Repair is often a more cost-effective solution than other repair methods, especially for smaller cracks and surface damage.

Liquid Concrete Repair can be used to restore the appearance of damaged concrete surfaces, making them look new again.

Liquid Concrete Repair is designed to be durable and long-lasting, helping to prevent further damage to the concrete surface.

Liquid Concrete Repair can be used on various types of concrete surfaces, and can be tinted to match the color of the surrounding concrete. Liquid Concrete Repair (LCR) can be used in a variety of concrete applications, including:

  • Concrete Driveways
  • Concrete Sidewalks
  • Concrete Car Garages
  • Concrete Parking Lots
  • Concrete Garage floors

LCR is particularly useful for small to medium-sized cracks and surface damage, and is suitable for both indoor and outdoor concrete surfaces. It is also ideal for repairing concrete surfaces that are subject to heavy use, such as driveways and sidewalks, as it provides a durable and long-lasting repair.

What is rebar?

Rebar is short for reinforcing bar and is a type of steel bar that is used to reinforce concrete structures. It is made of high-strength steel and has a rough surface that helps it bond to the concrete. Rebar is placed in concrete before it is poured and provides additional tensile strength to the concrete, helping to prevent cracking and collapse under stress.

Rebar is placed in a grid-like pattern within the concrete, with the bars spaced a certain distance apart and tied together with wire. This helps distribute the stress placed on the concrete evenly, reducing the risk of cracking and failure.

Rebar is an economical way to add strength to concrete structures, as it is relatively cheap and easy to install. It is widely used in construction, particularly in the building of concrete bridges, buildings, and other large structures.

Rebar should not be confused with post-tensioned tendons, which are also used to reinforce concrete structures. Post-tensioned tendons are high-strength steel cables that are placed in a concrete structure and then tightened to create tension. The tension in the tendons helps to hold the concrete together and prevent cracking, making it a useful technique for repairing large concrete structures, such as bridges and high-rise buildings.

What are slab-on-grade post tension repairs?

Slab-on-grade post-tension repairs refer to the repair of concrete slabs that have been constructed using post-tensioning techniques. A slab-on-grade is a concrete slab that is poured directly on the ground and is used for a variety of purposes, such as flooring in buildings, driveways, and parking lots.

Post-tensioning is a technique used in the construction of concrete slabs that involves placing high-strength steel cables (post-tensioned tendons) within the concrete before it is poured. The tendons are tightened after the concrete has been poured and cured, creating tension within the concrete that helps to prevent cracking and failure.

Slab-on-grade post-tension repairs refer to the repair of cracks and other surface damage in concrete slabs that have been constructed using post-tensioning techniques. The repairs may involve repairing the concrete surface, or repairing the post-tensioned tendons themselves.

Some benefits of post-tensioned slab-on-grade repairs include:

Increased durability
The post-tensioning provides additional strength to the concrete, making it more resistant to cracking and other forms of damage.

Improved load-bearing capacity
The post-tensioning helps to distribute stress evenly across the slab, increasing its load-bearing capacity.

Slab-on-grade post-tension repairs are often more cost-effective than replacing the entire slab.

Minimal disruption
The repairs can often be done with minimal disruption to the surrounding area, making them a good choice for repairing concrete slabs in busy locations.

Aesthetically pleasing
The repairs can restore the appearance of the concrete slab, making it look new again.

Are concrete and cement the same thing?

No, concrete and cement are not the same thing. Cement is a key ingredient in the mixture that forms concrete. Concrete is a mixture of water, aggregate (such as sand, gravel or crushed stone), and cement that hardens over time to form a solid mass. Cement acts as a binding agent in concrete, holding the other components together and allowing the mixture to harden into a strong and durable building material.

Cement is typically made from a mixture of limestone, clay, and other minerals that are processed and heated to create a powdery substance. This substance, known as clinker, is then ground into a fine powder to form cement. The exact composition of the raw materials and the process used to create cement can vary depending on the type of cement being made and the manufacturer.

The raw materials used to make cement are abundant and widely available, making it a widely used and accessible building material. The majority of cement production takes place in large-scale factories, which extract the raw materials, process and heat them, and then grind the resulting clinker into a fine powder for use in construction projects.

Concrete is made by mixing together a mixture of cement, water, aggregate (such as sand, gravel, or crushed stone), and any additional ingredients that may be included to improve its properties (such as air-entraining agents, pozzolanic materials, or chemical admixtures).

This mixture is typically produced in a concrete plant, where the ingredients are carefully measured and mixed to ensure consistent quality and performance. The mixture is then transported to the construction site, where it is poured into forms and shaped to the desired shape. Over time, the concrete hardens and sets into a solid, durable material.
