Commercial Buildings — Parking garages, office complexes, warehouses, and shopping centers.

Industrial Facilities — Factories, distribution centers, and large storage buildings.

Residential Projects — High-rise buildings, large apartment buildings, large homes with large floor plans.

Bridges & Overpasses — Post tensioning is also used in bridge construction to handle the large amount of weight and strain they are put under.

Tennis, Basketball, and Pickleball Courts — You may be surprised to find out that a lot of outdoor sports courts use post tensioned slabs. The post tensioned slabs allow for a level playing surface and a long lifespan without cracks.

Soil Conditions — Post tension slabs are ideal for some soil types found in North Carolina. We have 7 different types of soil in North Carolina. Some of those soil types are specific site locations that have poor quality soil that is subject to erosion and settling. Post tensioned slabs are ideal for high water tables and poor soil because they are able to resist ground movement.

Heavy Loads — When compared to traditional concrete slabs, post tensioned slabs are less likely to crack due to shrinkage, temperature changes, and external loads. If a concrete slab is likely to support heavy loads, post tensioned slabs are an ideal alternative to traditional concrete slabs.

Structural Instability — If your project requires more structural stability, post tensioned slabs can provide that additional stability. Post tensioned slabs are more rigid than traditional concrete slabs. Therefore, they are able to handle instabilities under the ground. In other words, post tensioned slabs can lead to increased stability and allow the structure’s integrity to stay intact over the long term.

Localized Settling — When one side of a foundation sinks faster than the others, this is referred to as localized settling. Localized settling can cause cracks and other structural issues. Post tensioned slabs are usually necessary for tall buildings because localized settling could cause a lot of damage.

Planning & Design — If there is not an existing blueprint design, our highly experienced team of concrete experts designs the post tensioned slab based upon the project’s requirements. The planning and design phase is one of the most important phases of a post tensioned slab project. Part of the design process includes designing the placement of the steel cables in order to optimize the load distribution and structural integrity.

Formwork & Tendon Placement — The next step is to set up the forms that the concrete will be poured into. Then steel cables (tendons) are positioned and run through conduit so the steel cables cannot come into direct contact with the concrete.

Concrete Pouring — Concrete is then poured around the steel cables where the slab structure is created. It is critical to make sure the concrete fully surrounds the steel cables (tendons) so there is a solid foundation for tensioning the slab.

Tensioning Cables — Once the concrete has fully cured, the steel cables (tendons) are able to be tightened by using hydraulic jacks. When the cables are tightened it compresses the concrete and enhances its load-bearing capacity.

Anchoring the Tendons — The heavy steel cables (tendons) are anchored in place at the edge of the concrete slab which locks in the strength of the post tensioned slab. Then the concrete can be finished so it can be made to reflect the desired texture and appearance.
