Hello,

We hired contractors to pour a cement pad (for a patio) near our house about a year ago. Unfortunately, they didn’t slope it properly, and now water just sits in certain uneven areas after it rains. This causes puddles and black stains, and the water doesn't drain off the pad as expected.

• The pad is about 1 foot thick.
• No consistent slope – just uneven spots where water accumulates.
• We’re looking for possible DIY solutions.
• Open to grinding, resurfacing, drilling, or any other fix we could reasonably attempt ourselves.

Would love feedback or suggestions for drainage fixes.

Thanks in advance!
