How much fall should be allowed for proper drainage of a flagstone patio?

For proper drainage of a flagstone patio, a fall of 1 to 2 percent is generally recommended, which translates to a slope of about 1/8 to 1/4 inch per foot. This slight slope ensures that water drains away from the patio and prevents pooling. It's important to direct the drainage toward landscaped areas or away from any structures to avoid water damage. Proper installation and grading are key to maintaining the integrity of the patio and its drainage.
