What Fall Should You Have on a Patio?

When it comes to designing a patio, the aspect of fall is crucial to ensure proper drainage and prevent water pooling. The appropriate fall on a patio is determined by the industry standard ratio of 1:80, suggesting that the patio should slope down 1 unit for every 80 units of distance. However, it’s important to note that this ratio may vary depending on the specifics of your project.

What Is the Maximum Fall for a Patio?

When planning the construction of a patio, it’s essential to consider the appropriate fall or slope for optimal drainage. The ideal slope for a patio is typically recommended to be ΒΌ inch for every foot. This translates to roughly a two percent drop, which ensures that water will flow away from the structure and prevent any potential water pooling or damage. However, it’s important to note that specific regulations may vary depending on your state or local building codes. Therefore, before undertaking any patio construction project, it’s advisable to thoroughly check the appropriate regulations to ensure compliance and avoid any potential legal issues.

When determining the fall for your patio, it’s also important to consider factors such as climate and surrounding landscaping. Areas that receive heavy rainfall or are prone to flooding may require a steeper slope to ensure proper drainage, whereas drier regions may tolerate a gentler slope.

The Potential Consequences of Inadequate Fall on a Patio, Such as Water Pooling or Damage

  • Increased risk of accidents
  • Potential for injury from slips and falls
  • Possible damage to the patio surface
  • Water pooling leading to deterioration
  • Formation of cracks or uneven surfaces
  • Reduced aesthetics of the patio
  • Difficulty in maintaining cleanliness
  • Potential for mold or mildew growth
  • Long-term structural damage
  • Inconvenience and costly repair or replacement

Having the right slope for a paver patio is crucial to ensure proper drainage and prevent water pooling. Building the patio with a gradient of at least 1 inch for every 8 feet is recommended to divert rainwater away from the foundation and avoid potential flooding issues.

What Is the Best Fall for Pavers?

When it comes to building a patio with pavers, one crucial factor to consider is the appropriate slope or fall. The right slope ensures effective water drainage and prevents issues such as water pooling, flooding, or damage to the foundation. A suitable gradient for a paver patio is to build it with a slope of at least 1 inch for every 8 feet.

The primary purpose of the slope is to allow rainwater to easily drain away from the patios foundation. Without proper drainage, accumulated water can seep into the ground, potentially causing flooding in basements or lower levels. By incorporating the recommended slope, you can ensure that excess water flows away and doesn’t cause any damage.

How to Properly Calculate and Measure the Slope for a Paver Patio

When it comes to creating a patio with paver stones, it’s important to ensure proper drainage by calculating and measuring the slope for the patio. The slope determines the angle at which water will flow off the patio surface, preventing any potential pooling or water damage.

To determine the ideal slope for your patio, you’ll need a few tools including a level, string, stakes, and a measuring tape. Here’s a basic step-by-step guide:

  1. First, decide on the direction where you want the water to drain. Typically, it’s best to slope the patio away from your house or any existing structures.
  2. Next, use stakes and string to mark the boundaries of your patio area.
  3. Measure the distance between the highest point and lowest point of your patio area.
  4. Based on this measurement, you can calculate the slope. As a general rule, a slope of 1/4 inch per foot is recommended for proper water drainage.
  5. Start from the higher end of the patio and dig a trench that gradually slopes downwards.
  6. Use a level and string to ensure that the slope is consistent across the entire patio area.
  7. Once you’re satisfied with the slope, you can begin laying the paver stones.

Remember, the proper slope ensures that water doesn’t accumulate on your patio, which can lead to issues such as standing water or erosion. By taking the time to calculate and measure the slope correctly, you can create a patio that’s both functional and aesthetically pleasing.


In conclusion, determining the appropriate fall for a patio depends on various factors and the specific requirements of the project. While the industry standard ratio for fall is typically 1:80, it’s important to consider any unique circumstances or site conditions that may necessitate adjustments to this ratio. Ultimately, the goal is to ensure effective water drainage and prevent pooling or potential damage on the patio surface. Consulting with a professional or expert in patio construction can provide invaluable guidance in determining the most suitable fall for your patio, ensuring both functionality and aesthetic appeal for years to come.
