Is Durock or cement board a better flood option than EnduraFlood?

Cement board resists surface water better than gypsum drywall, but it is usually finished with taped seams and paint similar to traditional drywall. Once installed, it functions as a fixed assembly. It is not engineered as a removable recovery system and typically still requires demolition to access wet wall cavities after a water intrusion event.

Choosing a Wall System After a Flood

Q: Can I use generic PVC panels instead of EnduraFlood?

Generic PVC panels can provide a water-tolerant surface, but they are not engineered as a complete wall recovery system. They do not integrate with a removable base detail, they are not designed for cavity inspection and controlled drying, and they may lack published testing documentation.

Q: How is EnduraFlood different from gypsum drywall?

Gypsum drywall absorbs water and usually requires disposal after flooding. Even minor water intrusion often leads to cutting out and replacing the lower wall section. EnduraFlood is designed so the lower section can be removed and reinstalled without discarding the entire wall assembly.

If you’ve already done a flood cut, the wall you put back decides what happens next time. Gypsum drywall soaks up water again. Even a waterproof wall still has to come off so the wall behind it can dry.

The best wall to put back after a flood is one that doesn’t absorb water and can be opened so the wall cavity can dry. Gypsum drywall fails the first test. Cement board and taped PVC boards fail the second. EnduraFlood waterproof drywall was designed to pass both.

What others may offer you instead

After a flood, many contractors will offer one of three ways to replace the sheetrock they cut out. Each has the same problem in a different form: the wall either gets ruined again next time, or it’s sealed shut so you can’t reach the wet insulation and studs behind it where mold grows. Some also have no published fire testing, which matters in a room people live in.

Option 1: Put new gypsum drywall back and hope it doesn’t flood again

Next flood, the sheetrock has to be cut out again, then hung, taped, and painted all over.
Weeks of dust and waiting on contractors.
A lot of people leave their walls open all season because they don’t want to do it twice.

Sheetrock soaks up water, so you’ll be cutting it out again.

Option 2: Cement board or PVC board, taped and painted like sheetrock

Cement boards handle water better, but once it’s taped and painted, it’s a fixed wall.
Water still gets behind it, and the only way in is to cut it open.
A wet wall you can’t see into is where mold grows.

Better board, same problem: you can’t open it.

Option 3: PVC panels from the home center

They are panels, not a wall system. Nothing is designed to come apart and go back together.
Most don’t publish fire testing, which matters in a bedroom or living room.
They look like a garage wall.

Fine for a garage. Not made to be a finished interior wall.

EnduraFlood: the waterproof drywall replacement that comes off

EnduraFlood started in our own flooded basement. The lower panels are waterproof and look like a finished wall. When water gets in, you take them off, dry the wall, and put the same panels back.

Frequently Asked Questions

Question: What should I put back after a flood cut?

Answer: Anything that can’t get wet will need to be cut out again next time. EnduraFlood replaces the lower, flood-cut section with waterproof panels that come off, so next time you dry the wall and reinstall the same panels instead of rebuilding.

Question: Does this work after hurricanes and in basements?

Answer: Yes. EnduraFlood is designed for coastal homes and basements. Customers who installed it after Hurricane Ian have since been through Helene and Milton.

Can I use generic PVC panels instead of EnduraFlood?

You can, and they’ll handle getting wet. But they aren’t designed to come off and go back on, so getting to the wall behind them to dry it is hard. Most also don’t publish fire testing. With EnduraFlood, the panels, trim, and base are all made to come off and go back on.

How is EnduraFlood different from gypsum drywall?

Question: How is EnduraFlood different from regular gypsum drywall?
Answer: Gypsum drywall, or sheetrock, soaks up water and has to be cut out and thrown away. EnduraFlood is waterproof drywall made without gypsum or paper. You take the panels off, let the wall dry, and put them back.

Isn’t cement board, like Durock, good enough?

Answer: Cement board handles water better than gypsum drywall. But it gets taped and painted like sheetrock, so once it’s up, it stays up. To dry the wall behind it, you still have to cut it open.
