Post Tension Cables

Post tension cables are an important part of many concrete foundations because they add strength and help reduce cracking over time. They are commonly used in residential and commercial construction to improve the performance of concrete slabs. When installed correctly, these cables help the foundation handle changes in soil movement and everyday structural loads.

How Post Tension Cables Are Installed

Before the concrete is poured, post tension cables are carefully placed inside the form boards according to the engineer’s design. The cables are arranged in both directions to create a strong reinforcement grid across the slab. Plastic chairs are used to hold the cables at the correct height, while steel anchors are secured at each end to keep everything properly positioned during the concrete pour.

After the concrete has gained enough strength, the cables are tightened using specialized hydraulic equipment. This process places the concrete under compression, making the slab stronger and more resistant to cracking. Proper tensioning is essential to ensure the foundation performs as designed.

Benefits of Post Tension Cable Systems

Post tension cable systems provide several advantages over traditional reinforced concrete. They help reduce shrinkage cracks, increase the overall durability of the foundation, and allow the concrete to better withstand soil movement. This makes them an excellent choice for areas where expanding and contracting soils are common.

Proper installation and tensioning should always be performed by experienced professionals following engineering specifications. Using quality materials and proven installation methods helps create a durable foundation that delivers long-lasting structural support and dependable performance for years to come.
