The playing surface of booce ball courts may consist of sand, decomposed granite, crushed oyster shells or any combination of the three allowing for minimal bounce. A solid base ground — with a layer of gravel or limestone if necessary — under the playing surface with proper drainage prevents water pooling.
One playing surface recommended by iBocce.com experts includes a 1/2-inch layer of crushed oyster shells on top of masonry sand. Once the sand is compacted and level, which a lawnmower can accomplish, a single 50-pound bag of shells adequately treats each 10 feet of the playing surface. This top layer should be raked until smooth; an extra bag of shells handy is helpful in maintaining the court.
Surfaces with softer than ideal playing and walking conditions may be treated with oyster shell flour for a firmer court with faster play.
While the standard court measures 90 feet by 13 feet, courts as short as 60 feet are not uncommon. Ideal perimeters are at least 6 inches in height to keep the ball in play and may consist of rail ties, block or cast concrete curbing or other suitable materials. Driving one-inch stakes along the frame help keep it secure and stable.
