Post-Tensioned Concrete Tennis Courts
Renner Sports Surfaces has over 27 years experience in the design and construction of post-tensioned concrete tennis courts, utilizing installers trained and certified by the Post-Tensioning Institute.
Post-Tensioned concrete is the preferred method for new construction and rebuilding of old tennis courts. Post-tensioning provides the best long term value for the following reasons:
- Ability to span unstable soils
- Increased resistance to settling and/or heaving
- Elimination of cold joints around net posts and fence posts
- Better uniformity of play
- More controlled slope for drainage
- Stable, attractive concrete edge
- Lower maintenance costs. This is important if future access is limited by landscaping, structures, etc.
- Eliminates the potential liability from structural cracking
- Ability to construct over existing courts, thereby saving valuable resources associated with demolition and disposal
The Post-Tensioned Concrete Construction Process
 |
1. laser grading After rough grading, the fine grade is achieved with the use of a laser controlled machine to create a true plane with tolerances to ± 3/8”. A perimeter beam is then excavated for the cable anchors. |
 |
2. cable placement Forms are set to grade using laser technology to assure uniform planarity throughout. The post-tensioning tendons are placed in both directions, with spacing determined by slab length and soil conditions.. |
 |
3. concrete placement Steel forms are used to assure uniformity of planarity. These forms are pre-drilled to accept the cable anchoring system. |
 |
4. concrete finishing Using equipment specifically designed for working large areas of concrete, the slab is finished in multiple directions, assuring planarity and texture across the entire court complex. |
 |
5. fence posts Fence posts are installed at the perimeter beam into the wet concrete to eliminate cold joints at these locations. |
 |
6. tendon stressing Once the concrete has achieved a specific compressive strength, the tendons are hydraulically tensioned to 33,000 p.s.i. and anchored at 28,900 p.s.i. Following final stressing, cable ends are cut off 3/4” inside the edge of slab and the pocket is grouted to prevent rusting of the tendons. |
 |
7. surfacing Standard surfacing consists of multiple coats of acrylic color applied to the prepared concrete. For resilience, a variety of cushioned surfaces are available. |
 |
8. accessories A full line of accessories, including windscreens, lighting, benches, and other amenities, is available to customize your project. |
