AridDek®: Resources

Yes. AridDek 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. Building Code Requirements – International Building Code – 2015.

No. The AridDek Waterproof Deck System is made up of interlocking deck boards that create the surface for your deck. And since it is a deck board, it cannot be cantilevered. A two-inch overhang beyond the fascia on the drainage side is suggested to shield deck joists from backsplash during heavy rain. Creating this small overhang also makes gutter installation easier.

No. Gutters or downspout installation is optional. Some people choose to use gutters to prevent water run-off interference with landscape features.

No: the AridDek Waterproof Deck System can be installed with a minimum number of readily available tools. No special tools are necessary.

No: although the AridDek system does have a built-in drainage channel, it cannot be used to replace joists, rafters, or support beams.

The AridDek Waterproof Deck System weighs 1lb per linear foot or 2lbs per square foot. (Approximately ½ the weight of traditional wood deck boards.)

Yes: we suggest a minimum 1/8” pitch per linear foot. This is a minimum pitch that will not be visible to the naked eye but provides a generous slope for water to drain away from the structure.

Yes: the AridDek system is manufactured from 45% recycled industrial and post-consumer aluminum scrap. As such, this product also assists builders in achieving points toward LEED credits 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.

No: the AridDek Waterproof Deck System is not slippery. AridDek has a powder-coated finish that provides steady footing in wet or dry conditions. Additionally, the ribbed surface provides additional traction and conceals the hidden fastener system for a gapless, skid-free surface.

Yes: the AridDek Waterproof Deck System was designed to be compatible with ACQ treated lumber. It is produced with a special powder-coated paint barrier to prevent ACQ contact with bare aluminum.

The maximum allowable joist spacing is 24 inches on-center when installing the aluminum deck boards on pre-existing or new joist structures.

Ariddek is a waterproof aluminum deck system that creates a low-maintenance deck surface while providing an integrated gutter system with dry, usable space underneath. Fortis is an eight-inch aluminum pre-grooved deck board that creates a low-maintenance deck surface similar to traditional deck boards in appearance. Fortis is not watertight because of the gap between the boards.

Yes, the AridDek Waterproof Deck System gets hot during the summer months, but the thermal conductivity of AridDek’s aluminum deck boards dissipates heat and provides a cooler deck surface than most wood or composite surfaces.

No. The AridDek Waterproof Deck System is extruded from an aluminum alloy (6005-T5 aluminum) that will not rust. However, as with other decking materials including wood, composite, or even concrete, steel products that come in contact with AridDek can rust and even stain your aluminum deck surface. Do not store metal objects that could rust and stain your AridDek system. Avoid metal working on AridDek, as well. When installing iron railings, protect AridDek with a non-plastic drop cloth to prevent grinding dust and weld splatter from settling on the surface of AridDek.
