ᐅ Kerb stones for terrace construction – slope is incorrect

Good morning,

I am currently looking for a practical solution to the following problem:
I have installed curb stones (4 x 9 m (13 x 30 ft)) and already filled the interior area with lightweight concrete so I can lay terrace slabs on top.
Now I have noticed—no idea how this happened—that the slope of the curb stones is 2% towards the house wall.
The terrace has an area of 36 m² (387 ft²), half of which will be covered.
What could I do to prevent damage later on?
Removing and reinstalling the curb stones would be a very big effort and should be the last option.
I’m considering options like cutting the curb stones with a diamond blade to create the correct slope away from the house wall—which of course would leave an unsightly surface.
Also thinking about installing a channel drain in front of the house wall, among other things.
I would be very grateful if you have any great tips for me? :-)

Best regards
Jochen

Oops, I misread that.
We are standing outside, looking towards the terrace.
The interior is filled and compacted with cellular concrete. From the outside, I should still have good access to the blocks.
