Post Tensioned Concrete Tennis Court
Wade walks you through this 125ft by 65ft concrete tennis court during the final placement of concrete. This concrete slab is 6" thick of 3500 psi concrete. It is post-tensioned to provide durability and longevity by reducing the chance for cracking.
What is post-tensioning? It is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Afterwards, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete
- It reduces or eliminates shrinkage cracking-therefore no joints, or fewer joints, are needed
- Cracks that do form are held tightly together
- It allows slabs and other structural members to be thinner
- It allows us to build slabs on expansive or soft soils
- It lets us design longer spans in elevated members, like floors or beams
