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

That depends on the site conditions. Is there enough space for an additional layer? Or does something need to be added on top first?
I think there is still room for that. The top layer is actually still missing.

What is supposed to go on it in the end?

I’m not sure yet. It was mainly about the slope issue, to make sure no water pools.

A concrete foundation has no slope. The slope is created by the screed applied afterwards, or wedge-shaped boards are placed under the final layer to achieve the slope.

I was referring to the concrete slab itself, not the strip footing beneath it.
