You need to measure the calculated slope from the string tied at the drainage end of the patio.
What is the minimum fall for a patio?
All of the paving slabs will need to be laid with a slight slope, around a 1 in 80 fall. This is so that pools of water don’t form on the surface of your patio. That means that for every 80cm your patio should fall by 1cm. The fall may vary dependent on the size of your patio but this is the optimum level.
How do you find the slope of a patio?
How to Measure the Slope for a Paver Patio Insert a stake at both the top and bottom of the patio. Tie a string around each stake. Slip a line level on the string and adjust the string so it is level between the stakes. Determine the amount of slope needed for the size of the paver patio.
How deep should type 1 be for a patio?

Should a patio be level?
The patio must be perfectly level, and it shouldn’t have any irregularities, dips or bumps. Making the patio flat isn’t the same as making it level. If the patio is perfectly level then pools of water will remain on it after rain or spraying it clean. The patio should therefore always have a slight slope.
How much pitch should a concrete patio have?

Should a patio Fall 2 ways?
Typically, you can use the industry standard ratio for fall of 1:80. However, this could differ depending on your project. In this example, that means that the patio should fall 1 unit for every 80 units of distance. This will provide you with the fall of the patio.
Should I slope my paver patio?
Patios must have a slight slope (1″ for every 4′ to 8′) for proper drainage. If you don’t provide enough slope, rainwater will settle into low spots, eventually softening and washing out the sand and subbase materials beneath. A flat or poorly sloped patio could even direct water into your basement.

Can a patio be built on a slope?
Keep in mind, a slope in the patio surface is needed to allow water and runoff to drain away from the house foundation. While a typical slope of 2% is recommended for driveways, patios can be set at a 1% slope. This will provide the balance and comfort for patio users, while still allowing for proper drainage.

Do I need a membrane under my patio?
In the vast majority of light-use constructions (patios, driveways, footpaths, etc) there is absolutely no need for a membrane to be placed between sub-base and the bedding layer: it achieves almost nothing, as a well-selected sub-base material will have what we call a ‘tight’ or ‘close’ finish, that is, there will be.
