FAQ: DryJoistEZ® Deck Drainage System

FAQ: DryJoistEZ® Deck Drainage System

  • image/svg+xmlimage/svg+xml
    How does the DryJoistEZ® Deck Drainage System differ from other deck waterproofing products?
    DryJoistEZ is a structural deck drainage system; this means that along with being 100% waterproof, it can also span up to six feet between supporting beams, which means it can replace some of the joists you would traditionally use to build your deck. The other popular deck waterproofing systems on the market are membrane systems and “under decking” systems that are installed below your deck joists. Both of these waterproofing methods come with labor-intensive installation processes and are effective only for limited amounts of time. The component materials used in the DryJoistEZ system are extruded from marine-grade aluminum, which makes them strong and extremely durable.  When the DryJoistEZ system is installed, it provides a solid waterproof structure that will never leak. Additionally, DryJoistEZ is mounted on top of your deck frame, which extends the life of framing materials.

    What type of deck boards can I use with the DryJoistEZ Deck Drainage System?
    DryJoistEZ provides the ultimate flexibility when it comes to your deck surface options.  Your choices include composite deck boards, hardwoods, softwoods, etc.  In essence, DryJoistEZ has support every four inches to six inches, which allows you to fasten your deck boards every 4”/6”/8”/10”/12”.

    Is the DryJoistEZ Deck Drainage System environmentally friendly?
    Yes: DryJoistEZ is manufactured using 45% recycled content from industrial and post-consumer aluminum scrap metal. It also channels rainwater, which reduces pollution from stormwater runoff. Because of its recycled content and its ability to manage stormwater, DryJoistEZ also allows builders to achieve points toward LEED credit certification based on the standards set forth by the LEED Green Building Rating System, within the categories of Recycled Content of Materials, Construction Waste Management, and Stormwater Design.

    My deck frame was built using ACQ (Alkaline Copper Quaternary) pressure treated wood, is it compatible with the DryJoistEZ Deck Drainage System?
    Yes: DryJoistEZ was designed for compatibility with ACQ treated lumber. It contains a special powder-coated paint barrier to prevent ACQ contact with the bare aluminum.
  • image/svg+xmlimage/svg+xml
    Do I need special tools to install or cut the DryJoistEZ Deck Drainage System?
    No: DryJoistEZ can be installed with a minimum number of readily-available tools. No special tools are necessary for installation.

    How do I cut DryJoistEZ?
    • Carbide-tipped blade for cutting non-ferrous metals
    • 12” blade-96 tooth
    • 10” blade 80 tooth
    • 7 ¼” blade 62 tooth
  • image/svg+xmlimage/svg+xml
    Do I need to pitch DryJoistEZ?
    Yes: we suggest a minimum of 1/8” downward pitch per foot (away from the house). This is a minimal pitch that will not be visible to the naked eye, yet provides a slope for water to drain away from the structure.
  • image/svg+xmlimage/svg+xml
    Can I cantilever DryJoistEZ? Is there a suggested overhang?
    Yes: A two-inch overhang beyond the header joist on the drainage side is suggested to shield the joists from backsplash due to heavy downpour and ease gutter installation. (Gutter installation is not required, but some people do choose to include one when they install DryJoistEZ.)
  • image/svg+xmlimage/svg+xml
    Is the DryJoistEZ deck drainage system compliant with local building codes and the International Building Code?
    Yes: DryJoistEZ meets or exceeds deck building code specifications and guidelines for aluminum structures, as recommended by AA ADM 1 and required by the International Building Code – 2015.
  • image/svg+xmlimage/svg+xml
    Do I have to install gutters or downspouts?
    Installing gutters or downspouts is not required, although they can be installed if you would like to incorporate your deck space with landscape architecture. (To direct the flow of water and prevent sod erosion.)
