What is a Har-Tru Clay Tennis Court?

Ironically, even though Har-Tru is often referred to as clay, it is actually created from crushed stone. It possesses extremely fine particles, making it a phenomenally smooth tennis court playing surface.  Har-tru surfaces have a reputation of strength and consistency when compared to other types of European clay courts.

Har-tru is an ancient natural green stone called Pre-Cambrian metabasalt, located in the Blue Ridge Mountains. It is ideal for tennis court construction because it is quite hard and angular. This level of angularity allows the stone particles to adhere closely together, fashioning a stable court surface. The amount of hardness coming from the stone allows for the court’s long lifespan.

Laser graded construction process:

Sport Surfaces specializes in Har-Tru and clay court construction using our exclusive dual-grade laser grading system, and high quality surfacing materials. This elite system allows us to build your new world-class Har-Tru clay court in an efficient and cost-effective manner. A layer of finely crushed green stone particles is installed over a porous base of crushed stone aggregate, producing a finished surface.

Even after many years of play, Har-Tru courts remain free of bumps, pits, buckles, and cracks. Every Har-Tru court is backed by a full complement of engineering and design services, as well as onsite technical consultation.

  • We start by laser grading the sub-base using our exclusive dual laser system to precisely prepare the subgrade
  • A concrete curb is installed around the perimeter of the court to hold the concrete screenings and clay in place
  • Installation of a standard above ground hydrocourt or hydrogrid irrigation system. Note: All of our irrigation systems have passed rigorous inspections for quality control. This ensures that they evenly disperse water to your entire court surface in order to maintain it at the proper consistency.
  • Crushed concrete is then laser graded over the entire court surface, providing proper stabilization and drainage as needed
  • 1 inch layer of Har-Tru is evenly dispersed over the entire surface and is then brushed, swept with a broom, and thoroughly rolled
  • Center anchor and net posts are retrofitted to industry specifications
  • Line tapes are installed, and secured with aluminum nails


Benefits of a Har-Tru or Clay Court Surface

  • Easy installation, with the bonus of its ability to be constructed directly on top of a hard court
  • Cracks are nonexistent, and surface repairs are much simpler and cost less than other types of court surfaces
  • It’s a porous surface that minimizes runoff and soil erosion.  Because of this eco-friendly quality, Har-Tru tennis courts are able to be installed in multiple locations.  Less zoning issues with municipalities
  • Low maintenance surface, with simple procedures for court surface care
  • 10-15 degrees cooler surface for game play than a hard court
  • Less bodily impact because of its softer surface, thus minimizing common tennis injuries
  • Har-Tru is a type of court surface that is also known as “fast-dry”, because of how efficiently it dries after a rainfall. This allows players to resume their games, even during a light rain shower


Har-Tru and Clay Court Daily Maintenance


Brushing the court is imperative to keeping a smooth surface after a tennis game. The loose top dressing is moved around the court to even out the playing surface. Brushing can also dry the court if it has just recently been watered. Be careful if you brush the court before watering, or if the court is too wet for usage.


It is mandatory to water your court to keep the court’s playing surface in perfect condition, guarantee proper traction, and maintaining court stability and firmness. The time to water a court is typically at night and during mid-day. The most crucial factor is to verify that the court is in a safe condition for game play.


Rolling a clay court is beneficial for ensuring firmness and speed. It works as a mechanism for stopping too much loose top dressing material from building up on the court surface.  Rolling a court during the morning is optimal because that is when a clay court has the most moisture.


Periodic Maintenance for a Har-Tru Court

  • Fixing low spots and divots
  • Checking tapes for areas where the lines are raised or the edges have curled upwards
  • Removing any grass or weeds that have grown around the court’s perimeter
  • Scarification of any hard or slippery spots
  • Clearing out the drainage system
