POST-TENSION COURTS

Post-Tension Courts

What is Post-Tensioning?

Post-tensioning is a method of strengthening concrete or other materials with high-strength steel strands of barsor tendons. Common applications include office and apartment buildings, parking structures, bridges, sports stadiums, and slabs-on-ground. Oftentimes this type of reinforcement allows for construction that would otherwise be impossible due to either site constraints or architectural requirements.

Although a Post-Tensioned system requires specialized knowledge and expertise to fabricate, assemble and install, the concept is easy to explain. Imagine a series of wooden blocks with holes drilled through them, into which a rubber band is threaded. If one holds the ends of the rubber band, the blocks will sag. Post-Tensioning can be demonstrated by placing wing nuts on either end of the rubber band and winding the rubber band so that the blocks are pushed tightly together. If one holds the wing nuts after winding, the blocks will remain straight. The tightened rubber band is comparable to a Post- Tensioning tendon that has been stretched by hydraulic jacks and is held in place by wedge-type anchoring devices. 

Post-Tension Benefits

Post-tensioning is a great way to reduce or eliminate control joints and resisting and controlling cracking as a result of the compression into the concrete by steel pre-stressing tendons. Without joints, you can experience better play and durability. These types of systems can be installed right over existing asphalt or clay courts, which eliminates the need for costly demolition. The surfaces are resistant to cracking, heaving, and settling.  Post-tensioned slabs are ideal for active New England soils.
