I've been recommended by two companies now to install an interior vapor barrier along my basement walls to prevent the water that is shooting out during heavy rains. The vapor barrier will stop water as soon as it passes through the concrete blocks and fall into the perimeter drain which leads to the sump pump. While I'm comfortable taking this route to prevent flooding in my basement, I can't help but worry about potential issues that may arise if I'm not preventing water from first entering my basement walls.
Am I overthinking this situation? Or should I consider sealing the exterior side of the basement?
