Yeah, sand alone can be tricky. I remember a build we did a few years back on heavy clay—thought we'd nailed it with a thick sand layer underneath. First big rainstorm, though, and the water just sat there like a pond. Ended up retrofitting a perimeter drain after the fact...not fun. Ever since then, I've been pretty cautious about drainage. Definitely worth the extra effort upfront to avoid that headache later.
"Ended up retrofitting a perimeter drain after the fact...not fun."
I can certainly relate—drainage issues can quickly turn a dream project into a nightmare. One thing I've found helpful, especially when dealing with clay-heavy soils, is incorporating layers of gravel and geotextile fabric beneath the sand. It provides a stable drainage path and prevents the sand from clogging up over time. A bit more effort upfront, but it pays off in peace of mind and longevity.
Been there myself—retrofitting drainage after the fact is a royal pain. Clay soil is brutal, it just doesn't let water through easily. Gravel and fabric definitely help, but honestly, sometimes you just can't predict every issue upfront. Learned that the hard way on my patio project...but hey, at least next time we'll know better, right? Live and learn.

Couldn't agree more on this point. Clay soil has been the bane of my existence on more than one project. A few years back, I tackled a foundation for a small workshop in my backyard. Thought I'd planned everything meticulously—graded the site, laid down gravel, installed drainage fabric, the whole nine yards. But after the first heavy rain, I realized I'd underestimated just how stubborn clay can be.
One thing that helped me immensely afterward was installing a French drain system around the perimeter. It wasn't exactly fun digging everything back up again (talk about frustrating...), but it made a huge difference in managing runoff and preventing pooling water. If you're still dealing with drainage headaches, I'd highly recommend looking into that option—it's a bit labor-intensive upfront but pays off in the long run.
Also, something I've learned over time is to always factor in extra drainage capacity from the start. Even if you think you've covered your bases, clay soil tends to surprise you. Now I always budget extra time and materials for drainage when working with heavy clay areas.
But you're right—sometimes experience is the best teacher. Every DIY project seems to come with its own set of unexpected challenges, no matter how prepared we think we are. At least each one makes us a little wiser for the next round...
Couldn't agree more on this point.
Good call on the French drain—wish I'd considered that earlier myself. Did you add any slope to your drain, or was it mostly level? I had a similar issue with clay soil pooling water around my shed, and found adding even a slight grade to the drainage trench made it way more effective. Clay really has a way of teaching us lessons the hard way...
