A patio fall or slope is the degree of decline or incline of the patio structure. The fall is required for adequate drainage of water from the patio surface, which would otherwise accumulate and damage the integrity of your patio. The fall is measured as an angle or as a percentage of elevation.
The patio slope or fall ensures that any water from rain or spillage is not accumulated on the patio’s surface. If the angle of the fall is not enough or too steep, water can accumulate and damage the structure over time. Water pools will also make your patio look unpleasant and prevent you from using it during wet weather.
If the patio fall is not adequate and water is allowed to accumulate over the patio surface, it can damage your patio in several ways.
The right patio slope has to be determined with as much accuracy as possible if you want the patio to last long. This includes determining the degree of decline/incline relative to the structure, which will allow effective drainage. The typical steps involved in this process are mentioned below.
2 inches ÷ 20 feet = 0.1 inches per foot
To convert this to a percentage, multiply by 100:
0.1 inches per foot x 100 = 1% slope
Patios are supposed to provide you with utility and add to your home’s aesthetic value. However, when building patios, one should ensure that the best practices are followed, including ensuring the proper patio slope. An adequate slope will provide the following:
Patios may lose shape and integrity over time, demanding specific alterations or an entirely new build. In cases where alterations can be made, a few steps can help you recreate your patio slope.
