Question 1

What is the AridDek waterproof deck system and how does it work?

Accepted Answer

AridDek is an extruded aluminum decking system that combines a finished walking surface with integrated water management. Its tongue-and-groove boards interlock while concealed drainage channels help capture water reaching the board connections. With the deck installed at the required pitch, water travels toward a planned discharge point instead of simply draining through open board gaps. This approach can help create a drier, more usable area beneath an elevated deck without requiring a separate under-deck ceiling system. AridDek still requires an appropriate supporting structure, including joists, beams, posts, foundations, and connections. The complete assembly must coordinate structure, slope, drainage, edges, outlets, and surrounding building details.

Question 2

What are the benefits of AridDek aluminum decking with integrated drainage?

Accepted Answer

AridDek may benefit homeowners who want an elevated deck while making better use of the space underneath it. The aluminum walking surface and integrated drainage channels work together to route runoff, potentially helping protect a patio, entrance, walkway, seating area, or storage space below. Aluminum also resists rot, splintering, and wood-destroying insects and does not require the recurring painting, staining, or sealing associated with wood decking under normal care. The powder-coated surface is designed for outdoor use, but maintenance is still necessary. Drainage channels, outlets, perimeter details, rail connections, flashings, sealants, and discharge points should remain accessible for cleaning and periodic inspection.

Question 3

What AridDek colors and design options are available?

Accepted Answer

Wahoo Building Products currently presents AridDek in Sandstone, Granite, and Artisan Clay powder-coated finishes. The material has the crisp, uniform appearance of extruded aluminum rather than a simulated wood-grain surface, which can influence how it coordinates with the home and surrounding outdoor space. Board direction, perimeter trims, fascia, railing colors, seams, drainage edges, and the appearance from below should all be considered during design. Product lengths, trim components, availability, and finish batches should be confirmed before ordering. Physical samples can also help because sunlight, shade, siding, masonry, landscaping, and other surroundings may change how a finish appears when viewed at the property.

Question 4

Can AridDek replace the decking on an existing elevated deck?

Accepted Answer

AridDek may be considered for replacement projects, but the existing structure must be exposed and evaluated before the aluminum system is installed. Framing conditions such as rot, corrosion, insufficient slope, irregular joist spacing, inadequate connections, incompatible dimensions, or out-of-plane joists may require correction. The existing structure must also support the planned deck loads, stairs, guards, furniture, and other project requirements. A new aluminum surface should not be used to conceal structural deficiencies. Homeowners considering this type of project can review our deck replacement services for related planning information. The final scope should identify required demolition, framing corrections, drainage planning, and concealed-condition procedures.

Question 5

How does AridDek manage water and help protect the space below?

Accepted Answer

AridDek manages water through interlocking boards and concealed drainage channels incorporated into the walking surface. When the boards are installed at the appropriate pitch, surface water and water reaching the connections move toward the drainage end and an established discharge location. This can help create a more protected area beneath an elevated deck. However, AridDek does not control every possible source of moisture around the structure. Walls, doors, siding, roofs, gutters, plumbing, rail penetrations, perimeter sealants, and wind-driven rain remain separate considerations. Water should also be discharged away from entrances, foundations, neighboring property, and other sensitive areas. Any leak requires evaluation of the complete assembly rather than the boards alone.

Question 6

What pitch and structural planning does an AridDek deck require?

Accepted Answer

Wahoo’s current AridDek guidance recommends a minimum pitch of 1/8 inch per linear foot away from the structure to help move water through the drainage system. Published guidance also identifies maximum joist spacing of 24 inches on center for qualifying configurations, but that maximum should not be treated as a universal framing specification. Actual support spacing depends on current load-and-span information, board layout, project loads, applicable requirements, engineering, and property conditions. The structure must also accommodate stairs, guards, concentrated loads, snow where applicable, and planned furniture or equipment. Existing decks may require blocking, leveling, reframing, or slope correction before AridDek can be properly installed.

Question 7

How do I clean and maintain an AridDek aluminum deck?

Accepted Answer

Routine AridDek maintenance includes cleaning the powder-coated surface with appropriate mild products and keeping board joints, drainage channels, deck edges, and outlets unobstructed. Leaves, dirt, ice, animal nests, and other debris can interfere with water movement if allowed to accumulate. Homeowners should follow current Wahoo Building Products cleaning guidance and avoid unfamiliar chemicals unless their compatibility has been confirmed. Sharp objects, unprotected grinding or welding, and rust-prone steel objects can also damage or stain the finish. Periodic inspection should include perimeter sealants, railing connections, outlets, visible fasteners, and the powder-coated surface. Persistent ponding, leakage, impact damage, scratches, or loose components should be evaluated before conditions worsen.

Question 8

What factors affect the cost of AridDek waterproof decking installation?

Accepted Answer

AridDek installation cost depends on the complete project rather than the aluminum boards alone. Deck area, dimensions, board lengths, selected color, shipping, site access, framing, support spacing, slope corrections, stairs, railing, perimeter trims, fascia, drainage outlets, demolition, disposal, permits, engineering, and other trade coordination can influence the estimate. Irregular deck shapes, numerous penetrations, or complicated water-routing conditions may require additional planning and labor. Replacement projects can also uncover framing damage or unsuitable geometry after the existing surface is removed. Homeowners can request a project estimate so a local provider can evaluate the property, system requirements, drainage endpoint, preparation, and proposed scope.

Question 9

What installation requirements should be considered for an AridDek deck?

Accepted Answer

An AridDek installation should coordinate structural support, deck pitch, joist spacing, board direction, fastening, perimeter conditions, drainage outlets, railings, stairs, penetrations, and connections to the building. Manufacturer-specified fasteners, sealants, cutting methods, and installation sequences should be used because incompatible materials or improper details can affect the aluminum system and its water-routing performance. Permits, engineering, inspections, association requirements, structural loads, and other requirements may vary according to the project and jurisdiction. The local provider should verify applicable requirements with the appropriate authorities and use current manufacturer documentation. An on-site evaluation is particularly important for replacement projects where existing framing, slope, connections, or drainage conditions may need correction.

Question 10

How does AridDek compare with vinyl membranes and other waterproof deck systems?

Accepted Answer

AridDek integrates water management directly into an aluminum walking surface, while other waterproof deck approaches manage runoff differently. A vinyl membrane such as Duradek creates a continuous flexible surface over a prepared substrate, while under-deck systems capture water beneath conventional deck boards. Other systems may integrate drainage into structural components while allowing a separate surface material. These differences affect appearance, framing, drainage, repairs, maintenance, and trade coordination. AridDek also differs from open-joint aluminum decking because its interlocking boards and concealed channels are designed specifically for water routing. The appropriate approach depends on the structure, desired appearance, intended use of the lower area, drainage requirements, maintenance expectations, and project-specific building details.
