How should I keep water out of my new DIY paver storage area?

Building a concrete curb is overkill for a small 20sqft pad and might actualy trap water inside the pavers instead of letting it drain away. If you used **polymeric sand** correctly—meaning you swept it in, vibrated the pavers to settle it, and then misted it—that sand acts like a flexible grout. It's designed to be weather-resistant and keep the base from washing out, even if it gets wet. Since this is at a low point, the main risk isn't rain from above but rather standing water or runoff from the driveway. If the pavers are sitting slightly higher than the surrounding ground, you're fine. If they're flush or lower, you just need to make sure the water has a path to keep moving. Adding a shower curtain is definitely janky and will just trap moisture underneath, which leads to mold and helps the pavers shift faster when the base stays soggy. Don't do it. Instead of a curb, look into **plastic edge restraints**. You can get them at any big box store. They’re L-shaped strips that you spike into the ground right against the edge of the pavers. They're invisible once you backfill with a little soil or mulch, and they do a much better job of keeping the stones from migrating than a DIY concrete curb would. And since you allready spent the time scoring those edge pieces, you want to make sure they stay locked in place.

Since you already have the base and sand down, just keep an eye on it after the first heavy storm. If you see the sand washing out, you might need to re-apply and ensure it's fully activated with water. But for a small bike storage area, you’ve likely done enought. Those 1/8 inch screws for spacers were a clever workaround, but make sure you pulled them all out before the sand went in so they don't leave rust spots on the stone later.

The screw spacers are a clever move, though I’d definitly be the person to leave one in and get rust spots. Since you mentioned it's a low point, I'm curious if the KolorScape base holds onto the water or if it lets it pass through to the dirt underneath? I'm looking at doing a small spot for my mower and I'm worried that if the sand seals everything up, the water will just sit on top like a pond. Does it actually feel solid enough to walk on when it's soaked?

If that spot is a true low point where water collects, the biggest thing you gotta watch for isn't the sand washing out, it's the base getting saturated and turning into mush. I've seen small pads like this sink or tilt after a couple of seasons if they're basially sitting in a puddle. Since it's allready done, just make sure the surrounding soil isn't higher than your pavers. You want that water to keep moving past the pad, not sit against the edges. If it starts pooling, you might just need to dig a tiny shallow trench—like a French drain lite—a few inches away to lead the runoff further down.
