Carpet pad is the cushion layer under wall-to-wall carpet that makes it feel soft and helps it last. It soaks up and holds water easily, so it’s usually the first thing that has to go after a leak.
What Happens to Carpet Pad After a Basement Flood
Carpet pad works like a sponge under your carpet. That’s great for comfort and terrible in a flood. Water soaks into the pad, gets trapped between the carpet and the slab, and has almost no way to dry out.
Wet areas need to be dried within 24 to 48 hours to prevent mold growth, and mold can grow on the underside of carpets and pads where you can’t see it. Porous materials like these may have to be thrown away once they’re moldy. After a basement flood, wet pad is usually pulled and replaced even when the carpet on top might be saved.
Federal flood guidance also rates carpeting as unacceptable below flood level. Carpet pad is the floor-covering cousin of underlayment, the foam or felt layer under click-together floors, and it has the same problem.
Our guide to basement flooring after a flood covers floors with no pad at all, like coated or polished concrete with an area rug on top.
Carpet Pad FAQ
What does a carpet pad do?
Carpet pad cushions your steps, makes the carpet feel thicker, and helps it wear more slowly. It also adds a bit of warmth and quiet. In a basement, it’s also the layer that soaks up and holds water.
Can you just replace a carpet pad?
Sometimes. After a leak, the pad is often swapped out while the carpet is cleaned and dried and put back. If the carpet was soaked and couldn’t be dried quickly, it usually goes too.
