What is the maximum slope allowable for concrete flatwork based on its use?

The maximum slope allowable for concrete flatwork is primarily determined to ensure the safety and functionality of the surface. A slope of 2% is generally considered to be the maximum for concrete flatwork, especially in applications such as sidewalks and driveways where water drainage is a concern. This percentage helps to facilitate proper drainage while minimizing the risk of slips and falls, making it essential for maintaining not only usability but also adherence to various accessibility standards.

In contrast, slopes greater than 2% may lead to issues such as pooling water or potentially creating hazardous conditions for pedestrians. Therefore, adhering to the 2% maximum slope guideline is crucial for both safety and compliance with regulations that govern concrete flatwork installation. Understanding these measurements ensures that the flatwork will function effectively for its intended use while also providing a safe environment for users.
