MDF vs Plywood vs Cleanstone: Which Material Will Survive Flooding?

MDF vs Plywood vs Cleanstone: Which Material Will Survive Flooding?

When the Auckland floods hit 2 years back, my whole bottom floor went underwater.

Watch video

Walls of Gib. Floors of laminate. Cabinets of MDF.

They swelled. They went moldy. They broke.


We were displaced for 8 months. Everything was ripped out and dumped in landfill—only to be replaced with the same materials...!


That’s why we started this test.

Three jars of water.

One with MDF.

One with plywood.

One with Cleanstone.


At week 2: MDF sunk to the bottom. At week 3: MDF and ply turned moldy, water turned brown. At 3.5 months: they’re rotting. But Cleanstone ... check the results out for yourself!


And it's not really a surprise... because Cleanstone is made from 100% recycled plastic. It’s waterproof. It’s durable. It’s designed to last.


Fit-outs typically get ripped out every 5–7 years.

Every replacement = more carbon emissions and waste.

Longevity is sustainability.


Climate change means more extreme weather events . Rebuilding the same way over and over isn’t working.


If you’re an architect, designer, or brand—your choice of material could be the difference between a fit-out that fails and one that survives.


So, your call: Would you trust a material proven to last in water—or keep using ones that collapse after weeks?
