Instant Classic: Har-Tru Green Clay

Har-Tru Green Clay is the world's leading clay court surface.

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, instantly recognizable, and improves visibility as well.

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.
