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 which 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 means 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.

A Har-Tru court requires water to remain compacted and stable. Water can be added to a court with an above ground or sub-surface irrigation system. Close to 75% of all new courts built today choose a sub-surface irrigation system such as Lee Tennis’ HydroCourt as it improves playability while reducing maintenance requirements.
