Functional advantage of Duradek membranes over Wood Decks


When wood is wet or coated with mildew, it is a very hazardous surface to walk on. Once moisture has seeped into the wood, it can warp, shrink or split the deck. Through natural process, any time a wood structure is left to the elements it will begin to rot. To avoid the inevitable, wood decks must be stained or painted at least every other year and failure to do so can result in costly repairs.


  • No ongoing maintenance – once Duradek is installed, there is never any reapplication required for it to continue its waterproofing performance so no risk of structural compromise from wood rot.
  • No chance of cracks or splinters to compromise waterproof protection or cause discomfort to bare feet.
  • With only a light scrub and rinse seasonally, Duradek will stay looking great – potentially for decades.


Duradek vs Composite Decking


As one of the newest deck building product innovations available, composite decking has experienced (and possibly still is experiencing) some pretty significant growing pains. With dozens of examples of product failures (cracking, shrinking, crumbling, excessive discoloration) and companies changing hands, many homeowners were left with no warranty protection. This led to some class action lawsuits that awarded only partial compensation. It was the homeowners that were left with the added cost to cover the difference to repair failed decks.


Functional advantage of Duradek membranes over Composite Decks

  • Duradek has a proven performance history and has been consistently manufactured in North America for nearly half a century, so there is no guesswork about its actual performance vs promises.
  • Duradek will never chip, crack or deteriorate, compromising structural safety.
  • Duradek has been around for over 4 full warranty cycles with the same ownership, so you can be confident that its warranty holds value and that the homeowner is protected.
