Post-Tensioned concrete courts have been around for years. Although more expensive than standard asphalt base courts, it has been proven that PT Courts can last for 50+ years if installed correctly.
What Is Post-Tensioning?
Post-tensioning is a method of prestressing. The tendons are tensioned after the concrete has hardened, and the prestressing force is primarily transferred to the concrete through the end anchorages. It isn’t just tennis courts that use a prestressing method. Many of today’s “high-performance” concrete structures, including landmark bridges and buildings, parking garages, and high-rise residential towers also employ post-tensioning techniques.
Why Is It Great For Courts?
Post-Tensioned concrete courts provide many advantages. The design of the system will greatly decrease the chances of cracking, settling, and ponding, which are common issues that tennis court owners face. This type of concrete can also withstand strong storms. Cushioned systems can be applied on the concrete slab, and work great on both indoor and outdoor courts.
Concrete provides a durable playing surface that will withstand mother nature and is less susceptible to both extreme hot and cold weather.
A post-tensioned concrete court slab will have a greater thickness than asphalt (4″ as opposed to 3″) and also have prestressed reinforcing steel. Once the cables are reinforced and tighten, the system becomes stronger than any other surface on the market.
Post-Tensioned concrete is becoming very popular for new construction and rebuilding of existing tennis courts where access can be tough to get to with new construction equipment.
Post-tensioning concrete provides long term value for the following reasons:
• Increased resistance to settling and/or heaving, ponding (low spots)
• Easy to control slope and drainage
• Eliminates the potential liability from structural cracking
• Ability to reconstruct over existing courts without any major excavation or transporting of material
• Cushioned Systems can be installed on the new slap
• Great for all sports
