ᐅ How to create a slope for a concrete patio?

Hello everyone

We have a concrete patio. However, it seems to have been poured rather carelessly and has very little slope. Far from the 2 to 3 degrees I have in mind as a standard.

I plan to request improvements but would like to know in advance what common methods are used to achieve this... Applying waterproofing membranes? Grinding with a concrete grinder? Adding an additional screed layer? Etc.

Thank you very much

I’m also interested in this. We bought an existing property where the previous owner built a huge concrete block in front of the house many years ago. Unfortunately, they never continued with the terrace construction, so only the bare concrete foundation remains. The frustrating part is that while they did include a slope, it’s in the wrong direction 😉

As a result, water drains toward the house wall, which has already caused damp walls in the basement.

What would be the easiest and most cost-effective way to fix this?

Either build an additional story at the front of the house or remove some material from the back. If it’s only a small amount, a grinding cup with a diamond blade is suitable for this. Just ask a tool rental company about it.
If it’s several centimeters (inches), I would probably go for an angle grinder and a proper demolition hammer.

That depends on the local situation. Is there enough space for an additional layer at all? Or does something need to be added on top?

What have you ordered?

2 degrees, and of course, the recognized rules of engineering standards apply...
