1. Steps to build a clay tennis court:

1. Start by building a cross-shaped drainage system at the bottom of the tennis court.

2. Use large gravel to build the first layer of foundation. The base thickness of this layer is 25 cm. After the gravel paving is completed, it needs to be surface compacted.

3. Use medium-sized gravel to construct the second layer of foundation. The thickness of this layer of foundation is 15 cm. After the gravel paving is completed, it needs to be compacted and crushed three times. Ensure that the surface gravel diameter is less than 0.5 cm, and the smoothing error does not exceed plus or minus 3 mm.

4. Pave the tennis court ground layer evenly mixed with special tennis red clay, fine gravel and anti-slip agent on the foundation surface. It is required to pave evenly, the diameter of granular objects on the surface of the site should not exceed 0.3 mm, and the color of the entire site must be uniform.

5. Use professional field line drawing paint to draw the lines.
