I've owned my house for three years now, and during this summer, we experienced some heavy rainfall. After 48 hours of continuous rain, I discovered a small leak (less than 2L) in my basement. My drywall, insulation, and wood appear to be dry, but I've been told that I might have a leak in the concrete wall. I do have a sump, but it doesn't have a pump. I'm looking for any advice on how to fix this issue. Thanks in advance!

Here are a couple of things to check: First, see if there's water pooling outside near your foundation, especially if a gutter is blocked. That could create pressure and push water through cracks. Second, consider checking your sewer pipe for any root issues that could cause backflow during heavy rainfall. It can be tricky!
Check if the outdoor water flow is directed away from your house. It's crucial—did the sump fill with water or just stay dry?
Good luck! I recently installed a battery backup sump system and had French drains put in after years of water issues. It’s made a huge difference—maybe consider that option if you're continually dealing with seepage!
Start by finding out where the water is coming from. Make sure the downspouts are directing water away from the foundation. I faced a similar problem; the previous homeowner had poor drainage solutions, and I had to dig trenches and install downspout extenders to solve it. It worked wonders!

Looks like I need to adjust my landscaping. What I thought was a sump is actually just a drain hole, and it didn't fill during the rain.
