A Strong Foundation

A post-tensioned slab on grade is a durable and economical alternative to other forms of conventional slab reinforcement. Some of the benefits include faster and more efficient construction schedules and less concrete and rebar potentially needed, resulting in savings.

Post-tensioning imparts an internal compressive force into the concrete. This increases resistance to deflections and cracking caused by expansive soil problems such as lift, shrinkage, or swelling due to temperature or moisture changes.

Providing better quality with lower costs, CMC Cable’s post-tensioning systems assure superior, lasting, high-quality surfaces and can improve performance and durability for a wide variety of applications:

• Single Family Residential Slab On Ground
• Multi-family Residential Slab On Ground
• Industrial and Commercial Floors
• Super Flat Warehouse and Industrial Floor Slabs
• Mat Foundations

* Engineering services provided by qualified partners in North Carolina.

Barrier cable types and sizes

Barrier cable for parking structures and other large-scale projects must be engineered very specifically. 
Success starts with the right product. Our barrier cable is most typically a half-inch diameter strand. We can 
also accommodate other sizes if needed, depending on the project's requirements. Three kinds of barrier 
cable systems are:

1] Galvanized
2] Plastic coated

The most widely specified coating is Class A-ASTM A475 galvanization. Enhanced coatings include a zinc-aluminum alloy ASTM B750 Galfan, which enhances 3-to-1 corrosion performance. Whether your goal is aesthetics and function or function alone, CMC Cable can work with you to ensure you 
have a solution that meets your project's requirements and provides only the highest safety and security.

Barrier cable anchorage and end fittings

CMC Cable provides standard end anchorages and specialized end fittings. Our qualified engineers understand the exact formulas to ensure our barrier cables can handle the proper force.

Standard end anchorages are utilized where access for stressing is available on the back side of the terminating support. These anchorages may be either recessed into a concrete column or wall or be surface mounted.

Specialized end anchorage components are available where access is not available on the back side of the cable termination. The end anchorage fittings and components may be protected through hot dip galvanizing (ASTM A153) or zinc plating conforming to ASTM B633.

All end anchorages and specialized end fittings allow for back stressing, as the Post-Tensioning Institute (PTI) requires.

Cutting into concrete should only be done under expert guidance. CMC Cable is a premiere provider of concrete scanning and coring services. As leaders in manufacturing and repairing PT cable, our team is highly experienced and qualified. Our concrete services 
have supported major building, bridge and structure renovations and construction.

Understanding the foundational risks and requirements of concrete coring and concrete scanning is essential. 

The risks include:

• Structural Instability
• Security Risks
• Property Damage
• Unanticipated costs and delays

Cable free guarantee

With our Cable Free Guarantee, we will replace or repair any PT cables damaged or broken by the CMC Cable team from coring at no additional cost to the customer. With each repair ranging from $7,000 to $10,000 a cable, you know we take our work quality seriously and are willing to reduce risk, even at our own cost.

Concrete scanning

A concrete scan is a preliminary step to executing a concrete demolition or concrete work. The plumbing, fiber optics, rebar, tension cables, and other items that may be contained within concrete walls must be located. A concrete scanner will provide real-time images to mark the location of these components.

Concrete scanning services can offer image-based detection and protect the utility of items encased in concrete. When construction teams plan a project based on accurate concrete scan images, they will avoid mishaps or delays.

Concrete scanning is commonly performed with a Ground Penetrating Radar (GPR). Whether facing a new construction project or carrying out a renovation, you can’t afford the cost of damage to structurally vital or costly materials. The cutting, coring, and drilling process should be based on the correct data from an effective concrete scan. Ground penetrating radar scanning is a non-invasive and efficient choice to achieve this.

GPR scanning is part of our process. The experts at CMC Cable can read concrete scan images and understand various aspects of a concrete structure. This understanding will inform the project. In concrete scanning, you may detect:

• Concrete reinforcement
• Concrete thickness
• Voids, including air gaps in the concrete slab on grade and more
• Embedded electrical lines and wires
• Fiber optic cables
• Reinforcing steel


Any project, from installing drains to demoing a concrete structure, should begin with a concrete scan.

Concrete corring

A concrete core project is accomplished by removing cylindrical sections of concrete. Core drilling concrete requires highly capable machines and operators. A concrete core drill penetrates the slab with precision. Any inaccuracies can result in high-cost repairs or incredible structural damage.


CMC Cable provides comprehensive engineering and construction work. Our concrete coring work is performed for general contractors, concrete contractors, MEP (mechanical, electrical, and plumbing) contractors, MEP engineers, structural engineers, forensic engineers, and building owners and managers.

Concrete drilling and concrete coring are often performed to enhance structural strength. The process should be dust-free, non-percussive, and give off low noise, making it an ideal choice for active work sites. Holes may be drilled at numerous angles. CMC Cable has knowledgeable teams that can achieve optimal results even in confined spaces or sensitive areas. With minimal disruption and virtually no cosmetic damage, concrete coring has many useful applications.



Our team has decades of experience providing world-class concrete restoration for structures on every scale. Our expert services include a talented group of engineers, specialists and concrete restoration teams. We are highly skilled and understand how to implement best practice work for concrete construction and repair in the markets we serve.
