Although it is referred to as clay, Har-Tru is actually composed of crushed stone. This is what makes it such an effective tennis court surface. It is more durable and more consistent than its European clay-court counterparts.

Har-Tru is made from billion-year-old Pre-Cambrian metabasalt found in the Blue Ridge Mountains of Virginia. It is a natural green stone that is extremely hard and angular, two very important qualities when it comes to tennis court construction. The angularity helps the stone particles lock together to form a stable playing surface.

The hardness provides exceptional durability. The natural green color is classically clay and instantly recognizable. The stone is crushed, screened, and mixed in the precise proportions necessary to produce a stable playing surface. It is then installed over a porous base of crushed stone aggregate to produce the final product.

Har-Tru is a unique crushed stone product that offers many benefits to court owners and tennis players.

1. Generically referred to as “fast-dry,” Har-Tru dries quickly after a rain and allows you to continue playing through light rain.
2. Har-Tru is 10–15 degrees cooler to play on than a hard court.
3. Har-Tru is easier on the body and reduces the incidence of common tennis injuries to the lower extremities.
4. Har-Tru is quickly and easily installed and can be constructed directly on top of hard courts.
5. Har-Tru is a porous surface that reduces runoff and soil erosion. Consequently, Har-Tru can be installed in locations where many tennis court surfaces cannot due to zoning restrictions.
6. Har-Tru never cracks and repairs are simple and inexpensive.
7. With simple, consistent care your Har-Tru court will last forever.
