The land on which the tennis courts are to be built should be bored to a level of at least 4′. The boring is to examine the sub-base material to ensure that there are no organic materials such as roots, tree stumps, peat, muck, etc. under the court area. The area also should be checked for water intrusion either from underground springs or an elevated water table. All care should be taken to insure that a consistent and stable sub-base exists prior to the construction of the tennis courts.
- Sub-base should be graded with a pitch of 1″ drop for every 20′- 28′ of run. The pitch should fall along the shortest distance from two parallel edges of the tennis court area. The pitch should fall, if possible, along the natural lay of the land.
- The orientation of the tennis courts should be 22 degrees West of true North. This keeps the sun from becoming a burden to the players as they are playing.
- The sub-base should have a compaction of at least 95%. However, most important is that the sub-base have a consistent compaction over the entire area on which the tennis courts are to be located.
- All vegetation should be removed and the ground sterilized to prevent growth. The area should be stripped of all surface and sub-surface vegetation prior to the beginning of construction.
- The area to be graded should have a buffer area of at least 5′ around the perimeter. Ex: If the court area is to be 120′ x 108′ the area to be graded should be 130′ x 118′.
- The lowest elevation of the tennis court surface should have a minimum height clearance from the surrounding landscaped area of 6″.
- If pos sible, no trees should exist within 10′ of the court area. If trees are to be planted, they should be maintained so that root encroachment and debris are kept to a minimum.
Base Stone Preparation:
The base stone acts as a stabilizing agent for the tennis courts. Typically base stone is comprised of large stone sizes up to 1.5″ and down. The base stone should have a minimum thickness of 2.5″ and a maximum thickness of 6″. In some cases (if the ground is very stable) base stone is not required. However, great care should be taken to make that decision. The base stones, function is to keep the court from moving or sinking over its normal life. Because of this, the stone should be compactible in nature and stable in its ability to lock up within itself. There are many different materials that can be used for base stone.
- The base stone should be consistent in depth throughout the court area. This is very important in that it keeps the drainage of the surface consistent.
- The surface of the stone should be level within 1/4″ with use of a 10′ straight edge.
- The base stone should be laid in 12′ to 15′ wide strips with each strip having both sides shot with a surveying level every 7′ to 8′. This is very important and must be carefully monitored. The use of a laser grader as an alternative to hand grading is highly recommended.
- The base stone should be rolled and compacted after installation.
- Any irrigation and sub-base excavation should be done before the installation of the base stone.
Stone Screenings Preparation:
The stone screenings perform a very important function. They provide the surface material with a water reservoir for the purpose of keeping the surface material moist. The screening layer also provides the contractor a means to achieve an almost perfectly graded and level base. It is important that the screening material holds moisture and that it also maintains compaction. Because of this, beach sand and crushed shell do not make a good base and should be avoided. Granite screenings are the perfect screening material, but there are other materials that will also work. The screening layer should be no less than 3/4″ and no more than 1 1/2″ (unless a modified base is used). Note: A modified base is a situation where the existing ground is very stable eliminating the need for use of the larger stone base. In this situation 1 1/2″ to 2″ layer of “screenings only” can be used. This however, is a special case and should only be attempted with consultation of an experienced tennis court contractor.
- The screenings should be consistent in depth throughout the court area. This is very important in that it keeps the drainage of the surface consistent.
- The surface of the screenings should be level within 1/8″ with use of a 10′ straight edge.
- The screening should be layed in 12′ to 15′ wide strips with each strip having both sides shot with a surveying level every 7′ to 8′. This is very important and must be carefully monitored. Again, a laser grader is highly recommended.
- The screenings should be rolled and compacted after installation.
- Any irrigation and sub-base excavation should be done before the installation of the screenings.
The Fast-Dry material is the finished product and needs to be placed with the utmost care and professionalism. The Fast-Dry material provides a smooth and comfortable playing surface for tennis players. It is very important that this material be placed at a very consistent depth in its installation and that the material is kept dry during storage and installation.
- The Fast-Dry Material should be consistent in depth throughout the court area. This is very important in that it keeps the drainage of and watering of the surface consistent.
- The surface of the Fast-Dry material should be level within 1/16″ with use of a 10′ straight edge.
- The Fast-Dry material should be laid in 12′ wide strips using 1 1/4″ straight steel pipe. A laser grader is the recommended method for the application of Fast- Dry material. However, some of the finest clubs in this country were built by hand, and that approach (if done properly) is also an excellent method.
- The Fast-Dry material should be watered, rolled and compacted after installation.
