I went the DIY route with French drains at my place after a similar storm surprise... Honestly, it's doable if you're comfortable digging trenches and hauling gravel. Just make sure you've got a solid slope away from the foundation—otherwise you're back to square one.
Did a similar project at my brother's place last summer—thought we nailed the slope, but after the first heavy rain, we had a mini lake forming near the shed. Turns out, even a slight miscalculation can really mess things up. Makes me wonder, did you use any specific tools or tricks to measure your slope accurately? We eyeballed ours at first...lesson learned, haha.
"Turns out, even a slight miscalculation can really mess things up."
Haha, been there myself—water pooling is no joke. Eyeballing slopes is tempting, but yeah...it rarely ends well. When I tackled a similar project, I ended up using a laser level. Sounds fancy, but honestly, you can rent one pretty cheaply from most hardware stores. It projects a straight line onto stakes or markers you set up, making it way easier to measure the slope accurately.
Another trick I learned (the hard way, of course) was double-checking with a simple string line and bubble level. It's old-school but surprisingly effective if you're careful. Just stretch the string tight between stakes at your desired slope and use the bubble level to confirm you're on track. Saved me from another backyard pond situation.
Still, even with tools, it's amazing how easily things can go sideways—literally. Glad I'm not the only one who's had to learn this lesson firsthand...
Laser levels definitely make things easier, but I wouldn't totally dismiss eyeballing just yet...hear me out. If you're dealing with smaller projects or rough grading, sometimes a quick visual check combined with a water hose test can save you the hassle of renting equipment. I've done this on a small patio extension, and it turned out surprisingly well. Maybe not perfect-perfect, but definitely no ponding. Guess it depends on the scale and how precise you really need it to be?
Totally get where you're coming from with the eyeballing thing. I've done a few small concrete pads myself, and honestly, sometimes simpler really is better. A laser level is awesome, no doubt, but for something like a patio or walkway, a hose test can be surprisingly effective. I remember doing a small shed foundation last summer—just eyeballed it and used a long straight board to check levelness. Turned out pretty decent...no pooling water, at least.
Guess my only hesitation would be if you're planning something structural or bigger-scale like a garage or workshop. At that point, I'd probably lean toward renting or borrowing a laser just for peace of mind. But for smaller DIY projects? Your method sounds perfectly reasonable to me. Did you have any issues with slopes or runoff afterward, or did the water hose trick pretty much nail it?
