POST-TENSION OVERLAY FOR DAMAGED COURTS
Post-tensioned concrete is the method utilized in the majority of new tennis
court construction. It is also the reconstruction method of choice for badly heaved or
cracked courts. This method has a pad of 4" thick concrete with 1/2"
sheathed tensioned cables centered in the concrete and anchored in a perimeter beam.
The concrete is poured monolithic, with the fence and net posts integrated into the slab. While the
concrete is curing, the cables are tensioned at approximately 7700 PSI, in both directions,
which puts an enormous amount of residual compression on the court. After curing, the surfacing system and lines are applied.
Concrete under tension is very durable and resistant to cracking & ground movement,
making post-tensioned construction an excellent long term value.
Post-tensioned concrete courts provide superior quality!
Their advantages over conventional asphalt courts are:
- Increased resistance to cracking.
- Increased resistance to settling and/or heaving.
- Elimination of cold joints around the net and fence posts.
- Better uniform planarity for play.
- More controlled slope for drainage.
- Stable, attractive concrete edge.
- Ability to integrate slab and retaining walls.
- Lower maintenance costs. **
**Very important if future access is limited by landscaping or other structures.
