Honestly, I think you did the right thing going a little overboard with the stakes and twine. I mean, it’s way cheaper to spend a few extra bucks on string than to deal with a soggy patio or have to redo concrete. Did you find it tricky to get the slope just right? I always worry about over-correcting and ending up with water running the wrong way... but at least you’re not chasing puddles like your neighbor.

Getting the slope right is honestly one of the most overlooked details, but it makes or breaks a patio. I’ve seen folks try to “eyeball” it and end up with water pooling right at the foundation. Using stakes and twine is smart, but I’d argue a long level or even a laser level is worth borrowing if you can. You only need about a 2% slope—anything more and you risk runoff issues, but less and you’re back to puddles. It’s a balancing act, but precision here saves a ton of headaches later.

I get why people focus on that 2% slope, but I’ve found it doesn’t always have to be that exact—especially if you’re dealing with really well-draining soil or using permeable pavers. Sometimes, going by the book can make things look a bit off in a small space. I actually did a patio last year where we went closer to 1% because the area was tiny and it drained perfectly fine.
One thing I think gets missed is how the surface materials play a role. If you’re using something like porcelain tiles or smooth concrete, water moves differently than on rough stone or brick. I’d say, before worrying too much about the math, check what’s happening after a rainstorm—sometimes you’ll catch little dips or high spots you’d never notice with a level.
And honestly, I’m a fan of dry-laying materials first, just to see how things settle. It’s not the most scientific method, but it’s saved me from a few headaches with surprise puddles...
I get where you’re coming from, but I’ve seen a few projects where cutting the slope too close ended up causing issues down the line—especially with freeze-thaw cycles or heavy storms. Even with good drainage, water can surprise you. I usually stick closer to the 2% just for peace of mind, especially if clients want low maintenance. Dry-laying is smart though, totally agree there... nothing like seeing how things actually settle before committing.

That’s a good point about water being unpredictable. I learned that the hard way on a project a few years back—client wanted everything as flat as possible for accessibility, and we thought we had drainage totally dialed in. First big storm, though, and there was pooling right where we didn’t expect it. Ended up having to retrofit a swale and some extra gravel. Since then, I always do a quick site walk after a heavy rain before finalizing grading plans. It’s amazing what you notice once water’s actually moving.
Dry-laying is a game changer, too. I’ve found that leaving things loose for a week or two lets you see where the natural low spots are, especially if you get a bit of rain in the meantime. Sometimes it means tweaking the plan, but it’s way easier than tearing up finished work. I get wanting to keep things as close to level as possible, but a tiny bit of slope—just enough to keep water moving—has saved me a lot of headaches.
