We're often asked how these vents mitigate or prevent severe foundational damage from floodwaters. The answer is that they do it by equalizing hydrostatic pressure. These vents permit floodwaters to freely enter and exit the basement or crawl space. It's an exercise in futility to try to keep floodwaters out. Hydrostatic water pressure from floodwaters around your home can easily reach tens of thousands of pounds. It's more than enough pressure to collapse large dams and retaining walls, so your comparatively weak home foundation wall doesn't stand a chance.
