We recommend that you have a license contractor install your game post for your sand court. After all the money and time you have invested, you do not want the poles falling down or breaking from improper installation. Net supports should be made of steel, or wood, or other material that will withstand tension and not bend or break. Supports should be at least 11.5 feet long buried at least two feet deep in cement. Make sure they're free of hazardous protrusions. If you use guy wires, they should be made of bright colors or marked with flags so they're visible. All anchors for guy wires and court lines should be level with the playing surface and free of sharp edges. For areas comfortably above sea level, the court area should be excavated two to three feet deep, depending on the depth of the sand and gravel base you intend to use. For low-lying areas, the court area should be excavated only about six to eight inches; you should end up building an elevated court rather than one that is flush with the ground. To keep dirt or grass from mixing in with the court sand, you may want to build a barrier around the court, either with wooden beams (such as railroad ties) or some type of low, solid fencing. This can be especially important for a court that is built slightly above ground. You should have a drainage system under the court. A drainage ditch should lead away from the lowest point of the court, and perforated drainage pipe should be laid in a zigzag pattern over the base of the area with one end capped and the other open to the drainage ditch. Drainage is very important. You don't want to be playing in a swamp.

Step by step:
1. Excavate the court area to your desired depth using a Bobcat or front-end loader. Our experts all advise against using a bulldozer or backhoe (the bulldozer won't be able to pick up and replace the dirt, and the backhoe won't dig a level surface). If you're in a low sea level area (for example, shoreline areas in Florida), the court should be built slightly above ground. Use the dirt you excavate to create a slight slope up to the court.
2. Arrange your court perimeter (if desired) around the edges of the excavated site. This keeps dirt and grass from leaking into the court and vice-versa. If you're using railroad ties or similar materials, our experts suggest covering the exposed top edges with some sort of padding to minimize injury potential. One expert says he's had great luck buying used rubber escalator handrail material from escalator-or companies and seating it atop his 2 x 6-inch wooden boundaries.
3. Lay out your drainage pipe, perforated side down, with the open end at the low point of the court. You may wish to wrap each section of pipe with some type of filter to keep sand from filling up the pipe: burlap is one choice although eventually it will rot. Our experts suggest using flex wrap or "handicap wrap," which can be bought at plumbing supply houses.
4. If you are using your own standards they should have a length of 11.5 to 13 feet, you will need to sink your poles at least two feet deep in concrete. Prepare your net standards by attaching hooks, pulleys, hook-and-eye hardware and any winch-type hardware. For longevity, if you're using wooden poles you should pre-treat them with a weather-resistant stain. If you're not using guy wires as supports, set your poles in the ground at a slight angle outward from the court to allow for any "bend" caused by eventual net tension. If you are using our #AGP-3 Game Standards you will sink them only 3.0’ feet below top sand level if the sand is 1 foot deep. If your sand base is deeper then you need to bring the concrete support with rebar, up into the sand. You will need to have the concrete in a L shape (key). You will also want the concrete to extend below your gravel base into the ground for support. Use a license contractor when installing your poles, if you do not know what you are doing.
5. Cover the pipe and the remaining court area with a one-foot thickness of small gravel. Various sizes seem to work, but the overall consensus is to use a small, pea-sized gravel known around the country as #56 gravel, #2 or #3 size gravel. Explain to your gravel supplier that it will be used for drainage, and he can recommend the size for your needs.
6. Cover the gravel with a screen-type filter to keep gravel and dirt from working its way up to the sand level. Again, burlap will work, but it will eventually rot, especially if you get a lot of rain. The best material is ground stabilization filter fabric, which is a woven poly-blend that won't deteriorate. You can find a supplier by calling a landscaping or excavating company for a referral.
7. Deposit your sand--one to two feet deep--and rake so it's level. With a good gravel base, one foot of sand is usually enough.
8. Attach your net, put down your boundary lines and you're ready to play.
Now for the big question: How much your basic costs will fall into three categories: sand and gravel, excavation equipment rental and court equipment. If you’re lucky enough to live on a coast, sand will probably be readily available at a reasonable cost. But unless you want to spend a lot of time with a shovel and a pickup truck at the beach, you'll need to purchase sand from a local sand pit or milling company (check your yellow pages). Sand comes in several grades, but our volleyball experts say this isn't the place to cut corners. Washed plaster sand, washed masonry sand, washed river sand or, if possible, washed beach or dune sand are recommended. Sand is sold either by the ton or by the yard, depending on where you live. You can calculate how much sand you'll need using the following formula: (Length x Width x Depth in feet divided by 27) x 1.6 gives you tonnage; (L x W x D) divided by 27 gives you yardage. Using this formula, a court approximately 40 x 70 feet with one foot of sand needs about 166 tons of sand. Gravel can be slightly cheaper, ranging from $5 to $14 per ton, although in some areas it can cost more than the sand. The formula for calculating the tonnage needed is the same as for sand.
