"Curious if you noticed any improvement after adding gravel beds and pipes—worth the hassle in the end?"
Funny you mention that...I had a similar battle with clay soil when we built our patio extension. Thought I'd nailed the slope, but after one heavy rain, boom—instant duck pond. Ended up biting the bullet and installing gravel trenches and drainage pipes. Honestly, it felt like overkill at first, but now even during downpours, everything stays dry. So yeah, for me it was definitely worth the hassle in hindsight.

Haha, been there myself...nothing like watching your carefully planned patio turn into a kiddie pool overnight. Gravel trenches definitely made a difference for me too, but I'm still tweaking things here and there. Did you find spacing or depth of the drainage pipes mattered much? Seems like everyone has their own theory on that one.

Honestly, depth made a bigger difference for me. I went about 18 inches deep with a slight slope away from the patio, and it handled heavy rains way better. Spacing seemed less critical, just keep it consistent.
Interesting you mention depth being more critical—I found spacing mattered quite a bit in my case. Maybe it depends on soil type or rainfall intensity? My soil is pretty clay-heavy, so drainage was a nightmare at first. I initially went about 20 inches deep, thinking deeper would always be better, but still had pooling issues after heavy storms. Then I adjusted the spacing, bringing the pipes closer together, and that seemed to help a lot more than going deeper.
Makes me wonder if there's a sweet spot between depth and spacing depending on your local conditions. Did you notice any difference based on the type of pipe you used? I started with the standard perforated black corrugated stuff, but switched to PVC later on. Honestly, the PVC seemed to handle the water flow better, but maybe that's just my imagination...
Also, did you wrap your pipes in fabric or gravel? I've heard mixed opinions on that too—some swear by landscape fabric, others say gravel alone is enough. I went with fabric-wrapped pipes surrounded by gravel, figuring it couldn't hurt, but now I'm curious if it was overkill. Would love to hear if anyone else experimented with different setups and noticed a real difference.
"Honestly, the PVC seemed to handle the water flow better, but maybe that's just my imagination..."
Funny you mention that—I had the opposite experience. When I first tackled drainage around my foundation, I went straight for PVC, thinking it'd be sturdier and more effective. But after a couple of seasons, I noticed sediment buildup inside the pipes, even though I'd wrapped them in fabric and gravel. Eventually, I switched to the black corrugated stuff, and weirdly enough, it seemed to resist clogging better. Maybe the flexibility helps shake loose debris or something?
Also, regarding fabric wrapping, I initially thought it was essential too, but after seeing how quickly mine clogged up, I ditched it altogether. Now I just use gravel alone, and it's been working fine for years. Could be a soil-type thing though—mine's sandy loam, so drainage is naturally decent. Clay-heavy soil might behave differently, I suppose.
