A well-drained area should be chosen, after which all trees and growth, including root systems should be removed. Remove the topsoil and other
unsuitable soils down to the clay or hardpan base. When grading the area, allow at least three feet beyond the fence lines and grade in one
plane with a slope of one inch in twenty-four feet, the slope to be in the direction of the most advantageous drainage.
Rough Sub Grade
A watering system should be installed which will provide adequate coverage of the court area. Conventional turf sprinklers can be installed with
piping under the court and controlled either manually or automatically. Next, a brick curb is placed around the perimeter of the court or court
battery. The finished curb elevation should be one half inch below the finished surface elevation, and the surface should be tapered out to meet it.
Court Construction Completed
The base of a Har-Tru tennis court must be stable as well as porous. A material that shifts or crawls when rolled should be avoided. The base should
not be compacted too much, because it is designed to absorb moisture that is later fed back to the surface in order to keep it moist for the best
possible play. While a crushed stone is preferred, other base materials may be substituted. The average thickness of the base is four inches with the
top one-half inch consisting of stone screenings.
Court Finished & landscaped
On the finished stone base a compacted one inch layer of Har-Tru surfacing is placed using laser grading techniques. The surface is applied eleven pounds per square foot.
Finally, the net posts, line tapes and net are installed in accordance with guidelines established by the United States Tennis Court and Track Builders
Association and the United States Tennis Association.
